PREPARATION FOR SERVICE
Stop the engine when refueling or servicing the fuelsystem. Do not smoke or allow open flame or sparks neargasoline. Gasoline is extremely flammable and highlyexplosive, which could result in death or serious injury.(00002a)
Good preparation is very important for efficient service work.A clean work area at the start of each job will allow you toperform the repair as easily and quickly as possible, and willreduce the incidence of misplaced tools and parts. A motorcyclethat is excessively dirty should be cleaned before work starts.Cleaning will occasionally uncover sources of trouble. Tools,instruments and any parts needed for the job should begathered before work is started. Interrupting a job to locatetools or parts is a distraction and causes needless delay.
NOTES
• To avoid unnecessary disassembly, carefully read all rel-ative service information before repair work is started.
• In figure legends, the number which follows the name ofa part indicates the quantity necessary for one completeassembly.
• When servicing a vehicle equipped with the Harley-Dav-idson Smart Security System (H-DSSS), you must firstdisarm the security system. Either keep the fob in closeproximity to the vehicle, or use Digital Technician to disablethe security system while the vehicle is being serviced andre-enable the system after service is completed.
SERVICE BULLETINSIn addition to the information presented in this Service Manual,Harley-Davidson Motor Company will periodically issue ServiceBulletins to Harley-Davidson dealers. Service Bulletins coverinterim engineering changes and supplementary information.Consult the Service Bulletins to keep your product knowledgecurrent and complete.

1.3DIAGNOSTICS/TROUBLESHOOTING
VOLTAGE DROPCheck the integrity of all wiring, switches, fuses and connectorsbetween the source and destination.
The voltage drop test measures the difference in potential orthe actual voltage dropped between the source and destination.
1. See ITEM A in Figure 1-4. Attach your red meter lead tothe most positive part of the circuit, which in this casewould be the positive post of the battery (5).
2. See ITEM B in Figure 1-4. Attach the black meter lead tothe final destination or component in the circuit (solenoidterminal from relay).
3. Activate the starter and observe the meter reading. Themeter will read the voltage dropped or the difference inpotential between the source and destination. An idealcircuit's voltage drop would be 0 volt or no voltagedropped, meaning no difference in potential.
4. See ITEM C in Figure 1-4. An open circuit should read 12volts, displaying all the voltage dropped, and the entiredifference in potential displayed on the meter.
NOTEOpen circuits on the ground side will read zero.
5. Typically, a good circuit will drop less than 1.0 volt. If thevoltage drop is greater, back track through the connections
until the source of the potential difference is found. Thebenefits of doing it this way are speed and accuracy.
a. Readings are not as sensitive to real battery voltage.
b. Readings show the actual voltage dropped, not justthe presence of voltage.
c. This tests the system as it is actually being used. Itis more accurate and will display hard to find poorconnections.
d. This approach can be used on lighting circuits, ignitioncircuits, etc. Start from most positive and go to mostnegative (the destination or component).
6. See ITEM D in Figure 1-4. The negative or ground circuitcan be checked as well.
a. Place the negative lead on the most negative part ofthe circuit (or the negative battery post). Remember,there is nothing more negative than the negative postof the battery.
b. Place the positive lead to the ground you wish tocheck.
c. Activate the circuit. This will allow you to read thepotential difference or voltage dropped on the neg-ative or ground circuit.This technique is very effectivefor identifying poor grounds due to powdered paint.Even the slightest connection may cause an ohm-meter to give a good reading. However, when suffi-cient current is passed through, the resistance causedby the powdered paint will cause a voltage drop orpotential difference in the ground circuit.

1.8BATTERY TESTING
GENERALThree different procedures may be performed to provide agood indicator of battery condition: a voltage test, a conduct-ance test, or a load test.
A battery may be tested, whether fully charged or not, viaconductance test. In order to perform a load test, however, thebattery must be fully charged.
VOLTMETER TESTThe voltmeter test provides a general indicator of battery stateof charge or condition. Check the voltage of the battery to verifythat it is in a 100% fully charged condition. Refer to Table 1-5.
If the open circuit (disconnected) voltage reading is below12.6V, charge the battery and then recheck the voltage afterthe battery has set for one to two hours. If the voltage readingis 12.7V or above, perform the LOAD TEST described in thissection.

2.1CHECKING FOR TROUBLE CODES
CHECK ENGINE LAMPTo diagnose Electronic Control Module (ECM) system prob-lems, start by observing the behavior of the check engine lamp.
NOTES
• See Figure 2-1. "Key ON" means that the Ignition Switchis turned to IGN and the Engine Stop Switch is set to RUN(although the engine is not running).
• When the Ignition Switch is turned IGN, the check enginelamp will illuminate for approximately four seconds andthen turn off.
• If the check engine lamp is not illuminated at Key ON orif it fails to turn off after the initial four-second period, thensee 2.2 INSTRUMENT MODULE (IM) SELF DIA-GNOSTICS.
1. See Figure 2-2. After the check engine lamp turns off fol-lowing the first four illumination periods, one of threeevents may occur.
a. The lamp remains off. This indicates there are nocurrent fault conditions or stored DTCs currentlydetected by the ECM.
b. The lamp stays off for only four seconds and thencomes back on for an eight second period. Thisindicates a DTC is stored, but no current DTC exists.
c. If the lamp remains on beyond the eight-secondperiod, a current DTC exists.
2. See 2.1 CHECKING FOR TROUBLE CODES, Code Typesfor a complete description of DTC formats.
NOTE
Some DTCs can only be fully diagnosed during actuation. Forexample, a problem with the ignition coil will be considered acurrent fault even after the problem is corrected, since the ECMwill not know of its resolution until after the coil is exercised bythe vehicle start sequence. In this manner, there may some-times be a false indication of the current DTC.

DIGITAL TECHNICIANHD-44750
There are two types of DTCs: current and historic. If a DTC isstored, it can be read using either a computer-based diagnosticpackage called DIGITAL TECHNICIAN (Part No. HD-44750)or speedometer self diagnostics. See 2.2 INSTRUMENTMODULE (IM) SELF DIAGNOSTICS.
NOTES
• Speedometer self diagnostics will display both current andhistoric DTCs.To differentiate between current and historicDTCs, a computer-based diagnostic package calledDIGITAL TECHNICIAN (Part No. HD-44750) must beemployed.
• All DTCs reside in the memory of the ECM, TSM/TSSM/HFSM, speedometer or tachometer until the DTC iscleared by use of the speedometer self diagnostics.2.2 INSTRUMENT MODULE (IM) SELF DIAGNOSTICS.
• A historic DTC is also cleared after a total of 50 ignitioncycles (start and run cycle) have elapsed. After the 50ignition cycle retention period, the DTC is automaticallyerased from memory providing that no subsequent faultsof the same type are detected in that period.
CurrentCurrent DTCs are those which presently disrupt motorcycleoperation. See the appropriate flow charts for solutions.
HistoricIf a particular problem happens to resolve itself, the activestatus problem is dropped and it becomes a historic DTC ratherthan a current DTC.
Historic DTCs are stored for 50 ignition cycles after any DTCwas last set as current to assist in the diagnosis of intermittentfaults. On the 50th cycle, the DTC will clear itself. The securitylamp will only indicate the existence of historic DTCs for twoignition cycles.
It is important to note that historic DTCs will exist wheneverthe system indicates the existence of a current fault. See2.1 CHECKING FOR TROUBLE CODES, Multiple TroubleCodes if multiple DTCs are found.
Diagnostic charts are designed for use with current DTCs. Asa result, they frequently suggest part replacement. When dia-gnosing a historic DTC, the charts can be helpful but shouldnot lead to part replacement without verification that the partis faulty.
SECURITY LAMPThe security lamp functions in the same manner as the checkengine lamp, except that it is controlled by the TSSM/HFSM.The security lamp will be turned on when codes are presentin the TSSM/HFSM.
RETRIEVING TROUBLE CODES
TOOL NAMEPART NUMBER
DIGITAL TECHNICIANHD-44750
There are two levels of diagnostics.
• The most sophisticated mode uses a computer baseddiagnostic package called the DIGITAL TECHNICIAN (PartNo. HD-44750).
• The second mode requires using the instrument module(IM) self diagnostics. IM, TSM/TSSM/HFSM, and ECMcodes can be accessed and cleared. See 2.2 INSTRU-MENT MODULE (IM) SELF DIAGNOSTICS for moreinformation..
MULTIPLE TROUBLE CODESWhile it is possible for more than one fault to occur and setmore than one trouble code, there are several conditions whichmay result in one fault setting multiple trouble codes:.
Serial data codes (DTC U1300, U1301, U1016, U1064, U1096and U1255) may be accompanied by other codes. Alwayscorrect the serial data codes before resolving the other codes.

SPEEDOMETER THEORY OF OPERATIONThe speedometer consists of a trip odometer reset switch andspeedometer. A speed sensor is mounted on the left side oftransmission case. The sensor circuitry is that of a Hall-Effectsensor that is triggered by the gear teeth of 5th gear on thetransmission mainshaft.
The output from the sensor is a series of pulses that are inter-preted by ECM circuitry, converted into serial data then sentto the IM. The IM converts the data to control the position ofthe speedometer needle. It also provides input to theTSM/TSSM/HFSM for turn signal cancellation.
The odometer mileage is permanently stored and will not belost when electrical power is turned off or disconnected. Thetrip odometer reset switch allows switching between the odo-meter, trip odometer and fuel range displays.
To zero the trip odometer, have the odometer display visible,press and keep the trip odometer reset switch depressed.Thetrip odometer mileage will be displayed for 2-3 seconds andthen the trip mileage will return to zero miles.
The odometer can display six numbers to indicate a maximumof 999999 miles. The trip odometer can display six numberswith a tenth of a mile accuracy for a maximum of 99999.9 miles.
2008 VRSC Diagnostics: Instruments 2-9
CUSTOM CD CREATIONS BY REPAIRMANUALSONCD.COM
TACHOMETER THEORY OF OPERATIONThe tachometer receives serial data from the ECM. The ECMreceives signal from CKP, the ECM converts signal to serialdata and sends it to the tachometer.The tachometer interprets
the serial data and converts it into tachometer needle move-ment.
Tachometer needle will turn from amber to red when RPM limitis reached.

2.9FUEL GAUGE OPERATION
GENERALSee Figure 2-14. With ignition switch ON or ACC, the fuelgauge and Fuel Level Sensor (FLS) are connected to +12 volts.The FLS determines distance to fuel and then outputs a voltagefrom a table lookup for distance versus volume.
Inoperative gauges may be caused by four circumstances.
• Sensor or Instrument Module (IM) not grounded.
• Malfunction in sensor or IM.
• Loss of accessory input, blown accessory fuse.
• Broken or disconnected wire from IM to fuel pump fromharness to sensor.

2.15DTC U1300, U1301 OR BUS ER
DIAGNOSTICSThe typical serial data voltage range is 0 volts (inactive) to 7volts (active). Due to the short pulse, voltages will be muchlower on a DVOM. In analog mode, a DVOM reading serialdata will show continuous voltage when active, typically 0.6-0.8 volts. The range for acceptable operations is 0-7.0 volts.
Diagnostic Tips• If serial data is shorted, these Diagnostic Trouble Codes
(DTCs) will automatically cause the check engine lamp toilluminate. The odometer will read "BUS Er" in this condi-tion.
• DTCs P1009 and P1010 may accompany DTCs U1300and U1301.
Diagnostic NotesIf a U1300, U1301 or "BUS Er" is present, perform diagnosticprocedures listed in 4.11 STARTS, THEN STALLS.

3.1TURN SIGNAL OVERVIEW
GENERALThe Turn Signal Module (TSM) has two major functions:
• Control turn signals.
• Serve as Bank Angle Sensor (BAS).
The optional, factory-installed, Harley-Davidson Smart SecuritySystem (H-DSSS) includes a Hands-Free Security Module(HFSM) which provides the same functions as the TSM, butalso includes security and immobilization functions.
SECURITY SYSTEM: JAPAN/KOREAThe security system on motorcycles sold in Japan and Koreameet the regulatory requirements of those countries. Thesystem incorporates a Turn Signal Security Module (TSSM).Complete details on operation, troubleshooting, and diagnosticsare found in the Appendix. See E.1 TSM/TSSM(JAPAN/KOREA) OVERVIEW.
TURN SIGNAL FUNCTIONS• Manual turn signal control: Manual activation/deactiva-
tion of left and right turn signal flashing sequences.
• Automatic turn signal cancellation: Automatic cancella-tion of left and right turn signal flashing sequences basedon either vehicle speed, vehicle acceleration or turn com-pletion.
• Hazard warning 4-way flashers: Four-way left and rightturn signal flashing capability.
• Turn signal lamp diagnostics: Self-diagnostics for shortcircuit and open lamp conditions on both left and right turnsignal systems. See 3.9 CHECKING FOR DIAGNOSTICTROUBLE CODES.
NOTE
The turn signals cannot be activated or deactivated when theIgnition Switch is in the ACC position. The turn signals canonly be activated or deactivated with the Ignition Switch in theIGNITION position.
MANUAL CANCELLATIONTo stop the turn signals from flashing, briefly depress the turnsignal switch a second time.
To switch turn direction signals, depress the switch for theopposite turn signal. The first signal is cancelled and theopposite side begins flashing.
AUTOMATIC CANCELLATIONPress the left or right turn switch to activate automatic turnsignal cancellation. There is no need to hold the turn switch in
when approaching the turn. The TSM/HFSM will not cancelthe signal before the turn is actually completed.
• When the directional switch is released, the system startsa 20 count. As long as the vehicle is traveling above 11.3km/h (7 MPH) the directional will always cancel after 20flashes if the system does not recognize any other input.
• If the vehicle speed drops to 11.3 km/h (7 MPH) or less,including stopped, the directionals will continue to flash.Counting will resume when vehicle speed reaches 12.9km/h (8 MPH) and will automatically cancel when the counttotal equals 20 as stated above.
• The turn signals will cancel within two seconds upon turncompletion. A sensor inside the TSM/HFSM cancels thesignal after the vehicle has been returned to an uprightposition.
NOTE
The bank angle cancellation function has an automatic calibra-tion feature. Ride the motorcycle for 0.4 km (.25 miles) atsteady speeds (upright) to calibrate the system. Performanceof bank angle function may not be optimal until this calibrationis performed. This self-calibration is performed automaticallyevery time the vehicle is started and ridden.
BANK ANGLE FUNCTIONS• Emergency engine shutdown: Will provide engine
shutdown when vehicle is tipped over.
• Emergency outputs disable: Will disable turn signallamps and starter motor when vehicle is tipped over.
BANK ANGLE RESTARTThe engine will shut off automatically if the vehicle is tippedover.The turn signals, starter motor, Electronic Control Module(ECM), fuel pump and coil will be disabled.
The odometer displays "tIP" when a tip over condition isdetected.
To restart the motorcycle after shutdown has occurred:
1. Return the motorcycle to an upright position.
2. Cycle the Ignition Switch OFF-ON before restarting themotorcycle.
CLUTCH/NEUTRAL INTERLOCK• Disables starter: Disables starter until either the clutch
lever is pulled in or transmission neutral is selected.

3.2HARLEY-DAVIDSON SMART SECURITY SYSTEM
COMPONENTSThe Harley-Davidson Smart Security System (H-DSSS) con-sists of three components:
• Hands-Free Security Module: See Figure 3-1. A elec-tronic module that functions both as the Turn SignalModule (TSM) and as the Hands-Free Security Module(HFSM).
• Hands-Free Antenna: See Figure 3-1. Mounted underthe seat of the motorcycle.
• Hands-Free Fob: See Figure 3-2. A remote control device,intended to be carried by the rider whenever the vehicleis being operated.
NOTE
Do not relocate any of the Security System components.

SECURITY IMMOBILIZATIONThe Hands-Free Security Module (HFSM) provides securityand immobilization functions not found on the Turn SignalModule (TSM). The HFSM will disable the starter and ignitionsystem. Additional functions include the ability to alternatelyflash the left and right turn signals and sound a siren (ifequipped) if a theft attempt is detected.
NOTE
The siren must be in the Chirp Mode for the siren to chirp onarming or disarming. See 3.6 WARNINGS AND ALARMS,Siren Chirp Mode (Confirmation).
Conditions that activate the security system when system isarmed include:
• Detecting tampering of the ignition circuit: Turn signalsflash three times, optional siren chirps once and then turnsoff. If the tampering continues, a second warning willactivate after four seconds. Continued tampering will causethe alarm to activate for 30 seconds and then turn off.Thetwo warnings/alarm cycle is repeated for each tamperingincident.
• Detecting vehicle movement: Turn signals flash threetimes, optional siren chirps once and then turns off. If thevehicle is not returned to its original position, a secondwarning will activate after four seconds. If the vehicle isnot returned to its original position, the alarm activates for30 seconds then turns off. The two warnings/alarm cyclemay repeat a maximum of 10 times with a 10 secondpause between cycles.
• Detecting that a battery or ground disconnect hasoccurred while armed: Siren, if installed, activates itsself-alarm mode. Turn signals will not flash.

CUSTOM CD CREATIONS BY REPAIRMANUALSONCD.COM
See 3.5 ARMING/DISARMING SECURITY SYSTEM for moreinformation.
NOTE
Disconnect the battery to prevent the siren (if installed) fromactivating within 5 seconds of turning the Ignition Switch toOFF/FORK LOCK. If the HFSM is armed, you must turn theIgnition Switch to IGNITION with a fob within range, again turnthe Ignition Switch to OFF/FORK LOCK and remove theMAXIFUSE before the 5-second arming period expires. Withthe MAXIFUSE removed, the battery can be disconnected.
HFSM FEATURESThe following information applies only to motorcycles equippedwith the Hands Free Security System (HFSM).
• Security lamp: See Figure 3-3. A lamp (key icon) withinthe speedometer face tells the rider if the system is armedor disarmed.
• Personal code disarming: If the fob is not available, theHFSM allows the rider to disable the security alarm andimmobilization functions with a five-digit personal code.
• Arming confirmation: When the HFSM is armed, thesystem provides visual feedback (confirmation) to the riderby flashing the turn signals and an audible "chirp" ifequipped with the optional smart siren and chirp mode isenabled.
• Disarming confirmation: When the HFSM is disarmed,the system provides an audible "chirp" (confirmation) ifequipped with the optional smart siren and chirp mode isenabled.
• Transport mode: It is possible to arm the security systemwithout enabling the motion detector for one ignition cycle.This allows the vehicle to be moved in an immobilizedstate.
• Starter/ignition disable: When armed the starter andignition system are disabled.
• Security system alarm: See Figure 3-4. The system willalternately flash the left and right turn signals and soundan optional Smart Siren if a vehicle security condition isdetected while the system is armed.
• Dealer service mode: This mode allows the dealer todisable security system via DIGITAL TECHNICIAN. Dealerservice mode is exited when module detects an assignedfob in range.

3.3H-DSSS ACTUATION
GENERALSetting up a vehicle TSM/HFSM depends on whether thevehicle has a Turn Signal Module (TSM) or the optional HandsFree Security Module (HFSM) security system installed.
SIDECAR CONFIGURATION
Only Touring Harley-Davidson Motorcycles are suitablefor sidecar use. Consult a Harley-Davidson dealer. Use ofmotorcycles other than Touring models with sidecarscould result in death or serious injury. (00040a)
All motorcycles ship with the H-DSSS set for use without asidecar installed. If a motorcycle is equipped with a TSM, nofurther actuation is required.
ACTUATIONActuation consists of assigning two FOBs to the system, andentering an initial PIN (Personal Identification Number). ThePIN can be changed by the rider at any time.
1. Configure HFSM motorcycles by assigning both fobs tothe vehicle.
2. Configure HFSM motorcycles by entering a PersonalIdentification Number (PIN) picked by the owner. Thepersonal code allows the owner to operate the system ifthe fob is lost or inoperable. Record the PIN in the Owner'sManual and instruct the customer to carry a copy (use thewallet card found in the Owner's Manual). See 3.4 PER-SONAL IDENTIFICATION NUMBER (PIN).
Once the system has been activated, it will always "arm" within5 seconds of turning the Ignition Switch to OFF and no motor-cycle motion.
FOB ASSIGNMENT
TOOL NAMEPART NUMBER
DIGITAL TECHNICIANHD-44750
Use DIGITAL TECHNICIAN (Part No. HD-44750) to assignboth fobs to the H-DSSS. Follow the menu prompts in theDigital Technician display and scan the fob serial number withthe bar code reader, or key-in the number from the keyboard.See a Harley-Davidson dealer.
NOTE
Each fob has a unique serial number. The label should beremoved from the fob and attached to a blank NOTES pagein the Owner's Manual for reference.

3.6WARNINGS AND ALARMS
WARNINGSA warning consists of three alternate flashes of the turn signalsand chirp from the optional Smart Siren. Warnings are issuedfrom an armed HFSM in the following order:
1. First Warning: A warning is issued whenever a personwithout a fob present attempts to move the motorcycle orturns the Ignition Switch to IGNITION.
2. Second Warning: If the motion continues or the IgnitionSwitch is not turned back to OFF, a second warning isissued within four seconds of the first.
3. Alarm: If the motion continues or the Ignition Switch isnot turned to OFF past the second warning, the SmartSecurity System will go into full alarm.
ALARM
ActivationIn the full alarm state, the turn signals flash alternately, and ifequipped with the Smart Siren, the siren will sound.
After 30 seconds of alarm, if no further motorcycle motion isdetected, the alarm will stop.
NOTE
Motorcycle must be returned to original parked position withIgnition Switch turned to OFF.
If motorcycle motion continues, the alarm will start again con-tinue for another 30 seconds.
The HFSM will repeat the alarm cycles 10 times for a total offive minutes, with a 10-second pause between alarm cycles.
NOTES
• During warnings and alarms, the starter motor and theignition remain disabled.
• The alarm will also activate the LED and vibration or aud-ible modes of a Harley-Davidson Security Pager. A pager
can operate either in silent or in combination with anoptional Smart Siren. The range of the pager can be upto 0.89 km (1/2 mile).
DeactivationThe alarm cycles can be discontinued at any time by movingan assigned fob to the motorcycle. The presence of the fobwill terminate the alarm.
SIREN CHIRP MODE (CONFIRMATION)
Chirpless ModeIn the chirpless mode, the siren does not chirp on arming ordisarming.
NOTE
Even when armed in the chirpless mode, the siren still chirpswarnings on movement and will activate the alarm throughcycles.
Chirp ModeOn arming in the chirp mode, the siren responds with twochirps.When disarming, the siren responds with a single chirp.
Switching ModesCycling quickly through two armings and disarmings will switchthe system from either the chirpless mode or the chirp modeto its opposite.
1. With the fob present, the Ignition Switch ON and thesystem disarmed, turn the Ignition Switch OFF.
2. When the system arms (2 flashes of turn signals), imme-diately turn the Ignition Switch back ON.
3. Wait until the security lamp goes out, then immediatelyturn the Ignition Switch OFF.
4. When the system arms (2 flashes of turn signals), imme-diately turn the Ignition Switch ON and wait for system todisarm.

3.8TROUBLESHOOTING
TURN SIGNALS (TSM/HFSM)Verify the operation of the turn signals and the integrity of thefuse protecting the turn signals before further troubleshooting.
SECURITY SYSTEM (HFSM)If the fob is present, and the security system is issuing "warn-ings" or "Alarm" when the motorcycle is moved, the reasonmay be one of the following:
1. Strong electromagnetic interference in the area you haveparked.
a. Verify you have not placed your fob in metalenclosure, or within 80.0 mm (3.0 in.) of other elec-tronic devices.
b. Place fob next to motorcycle and turn the IgnitionSwitch ON. After the system disarms, the fob can beplaced back in its carrying location.
c. Try moving the motorcycle approximately 4.57 m (15feet) away from the current parking spot.
2. The fob battery is dead. Use PIN to disarm the vehicle.Replace fob battery.
3. Fob is damaged. Use PIN to disarm the vehicle. Replacethe fob.
NOTES
• If your Security Icon is staying solid ON while you areriding the vehicle, take your vehicle to your dealer as soonas practical.
• Always lock the fork and take the ignition key with you foradded protection.
DIAGNOSTICS MODEThe TSM/HFSM measures the current when the turn signalsare used. If there is a burned out light bulb on one side, the
remaining light and the corresponding turn signal indicator flashat double the normal rate starting with the fifth flash.
Other diagnostic conditions monitored include:
• Short circuit in the turn signal wiring.
• Open circuit in the turn signal wiring.
• Stuck turn signal switch.
NOTES
• A stuck turn signal switch will disable the automatic turnsignal cancellation feature.
• If a stuck switch is detected, you must hold the left andright turn signal switches in for more than one second toactivate the four-way flashers.
See 3.9 CHECKING FOR DIAGNOSTIC TROUBLE CODESfor more information.
TROUBLESHOOTINGTo resolve TSM/HFSM faults, follow four basic steps:
1. Retrieve Diagnostic Trouble Codes (DTCs) usingspeedometer self diagnostics. See 3.11 INSTRUMENTMODULE (IM) SELF DIAGNOSTICS.
2. Diagnose system problems. This involves using specialtools and the diagnostic flow charts in this section.
3. Correct problems through the replacement and/or repairof the affected components.
4. After repairs are performed, the work must be validated.This involves clearing the diagnostic trouble codes andconfirming proper vehicle operation as indicated by thebehavior of the turn signals.

3.9CHECKING FOR DIAGNOSTIC TROUBLE CODES
GENERALProblems fall into at least one of five categories:
• Turn signal malfunction.
• Bank angle (engine disable).
• Clutch/neutral interlock (starter enable).
• Security lamp problem.
• Security system malfunction.
SECURITY LAMP DIAGNOSTICSTo diagnose system problems, start by observing the behaviorof the security lamp.
NOTES
• See Figure 3-8. "Key ON" means that the Ignition Switchis turned to IGNITION and the Engine Stop Switch is setto RUN (although the engine is not running).
• See Figure 3-9. When the Ignition Switch is turned toIGNITION, the security lamp will illuminate for approxim-ately four seconds and then turn off.
• If the security lamp is not illuminated at IGNITION ON orif it fails to turn OFF after the initial four-second period,the speedometer may need to be replaced. See3.11 INSTRUMENT MODULE (IM) SELF DIAGNOSTICS.If "BUS Er" is displayed on the odometer, it may take upto twenty seconds for the security lamp to illuminate.
• The security lamp will also light for eight seconds after thebulb check if historic Diagnostic Trouble Codes (DTCs)are present.The security lamp will stay on if current DTCsare set. If a historic DTC is present, the security lamp willlight for 2 ignition cycles or until the DTC is clearedmanually.
1. See Figure 3-10. After the lamp turns off after being illu-minated for the first four-second period, one of threeevents may occur:
a. The lamp remains off. This indicates there are nocurrent fault conditions or stored historic DTCs cur-rently detected by the HFSM.
b. The lamp stays off for only four seconds and thencomes back on for an eight-second period. Thisindicates a historic DTC is stored, but no current DTCexists.
c. If the lamp remains on beyond the eight-secondperiod. This indicates a current DTC exists.

DIGITAL TECHNICIANHD-44750
There are two types of DTCs:
• Current
• Historic
If a DTC is stored, it can be read using either a computer-baseddiagnostic package called DIGITAL TECHNICIAN (Part No. HD-44750) or speedometer self diagnostics. See 3.11 INSTRU-MENT MODULE (IM) SELF DIAGNOSTICS.
NOTES
• Speedometer self diagnostics will display both current andhistoric DTCs.To differentiate between current and historicDTCs, a computer-based diagnostic package calledDIGITAL TECHNICIAN (Part No. HD-44750) must beemployed.
• All DTCs reside in the memory of the Electronic ControlModule (ECM), TSM/HFSM, speedometer or tachometeruntil the DTC is cleared by use of the speedometer selfdiagnostics. See 3.11 INSTRUMENT MODULE (IM) SELFDIAGNOSTICS.
• A historic DTC is also cleared after a total of 50 ignitioncycles has elapsed. After the 50 ignition cycle retentionperiod, the DTC is automatically erased from memoryproviding that no subsequent faults of the same type aredetected in that period.
CurrentCurrent DTCs are those which are present during the currentignition cycle. See the appropriate flow charts for solutions.
HistoricIf a particular problem happens to resolve itself, the activestatus problem is dropped and it becomes a historic DTC ratherthan a current DTC. For example, intermittent output shortscan become typical historic DTCs.
Historic DTCs can only be retrieved using a computer-baseddiagnostic package called DIGITAL TECHNICIAN (Part No.HD-44750).
Historic DTCs are stored for 50 ignition cycles after any DTCwas last set as current to assist in the diagnosis of intermittentfaults. On the 50th cycle, the DTC will clear itself. The securitylamp will only indicate the existence of historic DTCs for twoignition cycles.
It is important to note that historic DTCs will exist wheneverthe system indicates the existence of a current fault. See3.9 CHECKING FOR DIAGNOSTIC TROUBLE CODES, Mul-tiple DTCs/Priority Order if multiple DTCs are found.
Diagnostic charts are designed for use with current DTCs andas a result they frequently suggest part replacement. Whendiagnosing a historic DTC the charts can be helpful but shouldnot lead to part replacement without verification the part isfaulty.

GENERAL
TOOL NAMEPART NUMBER
DIGITAL TECHNICIANHD-44750
To locate faulty circuits or other system problems, follow thediagnostic flow charts in this section. For a systematicapproach, always begin with 3.10 INITIAL DIAGNOSTICCHECK, Initial Diagnostics which follows. Read the generalinformation and then work your way through the flow chart boxby box.
Diagnostic NotesIf a numbered circle appears adjacent to a flow chart box, thenmore information is offered in the diagnostic notes. Many dia-gnostic notes contain supplemental information, descriptionsof various diagnostic tools or references to other parts of themanual where information on the location and removal ofcomponents may be obtained.
Circuit Diagram/Wire Harness ConnectorTableWhen working through a flow chart, refer to the illustrations,the associated circuit diagram and the wire harness connectortable as necessary.The wire harness connector table for eachcircuit diagram identifies the connector number, description,type and general location.
In order to perform most diagnostic routines, a Breakout Boxand a digital volt/ohmmeter (DVOM) are required. See3.12 BREAKOUT BOX: TSM/HFSM.
To perform the circuit checks with any degree of efficiency, afamiliarity with the various wire connectors is also necessary.
Job/Time CodesSome charts may contain warranty job/time codes. Dealershiptechnicians filing warranty claims should use the job/time codevalues printed in bold text underneath the appropriate repair.
Reprogramming ECMDiagnostic charts frequently suggest Electronic Control Module(ECM) replacement. In the event an ECM needs to be replaced,it must be reprogrammed using a computer-based diagnosticpackage called DIGITAL TECHNICIAN (Part No. HD-44750).See your dealer. Password learn procedure must also be per-formed. See 3.25 TSM/HFSM: PASSWORD LEARN.
INITIAL DIAGNOSTICS
Diagnostic Tips• If odometer reads "BUS Er" with the Ignition Switch turned
to IGNITION (Engine Stop Switch at RUN with the engineoff), check data bus for an open or short to groundbetween data link connector [91A] terminal "3" and ECMconnector [78B] terminal "5", HFSM connector [30B] ter-minal "3", speedometer connector [39B] terminal "2" ortachometer (if equipped) connector [108B] terminal "2".
• Check for an open diagnostic test terminal between datalink connector [91A] terminal "3" and TSM/HFSM con-nector [30B] terminal "3". With Ignition Switch turned toIGNITION, serial data bus voltage should be typically 0.6-0.8 volts. The range of acceptable voltage is 0-7.0 volts.
• To identify intermittents, wiggle wire harness while per-forming steps in the diagnostic check charts.
Diagnostic NotesEach reference number below correlates to a circled numberon the flow chart(s).

HARNESS CONNECTOR TEST KITHD-41404-B
Diagnostic Tips• If the siren is armed and the internal siren battery is dead,
shorted, disconnected, or has been charging for a period
longer than 24 hours, the siren will respond with threechirps on arming instead of two.
• The internal siren battery may not charge if the vehicle'sbattery is less than 12.5 volts.
• If the siren does not chirp two or three times on a validarming command from the HFSM, the chirp function hasbeen disabled, the siren is either not connected, notworking, or the siren wiring was opened or shorted whilethe siren was disarmed.
• If the siren enters the self-driven mode where it is poweredfrom the siren internal nine-volt battery, the turn-signallamps will not alternately flash. If the HFSM activates thesiren, the turn-signal lamps will flash. If the siren has beenarmed and a security event occurs, and the siren is in self-driven mode, the siren will alarm for 20 to 30 seconds andthen turn off for 5 to 10 seconds. This alarm cycle will berepeated ten times if the siren is in the self-driven mode.
• If the siren does not stop alarming after it has been armed,then either the HFSM output or siren input may be shortedto ground, or the siren vehicle battery connection is openor shorted to ground, or the siren vehicle ground connec-tion is open, or a security event has occurred. See3.6 WARNINGS AND ALARMSfor a description of alarmfunctions.
Diagnostic NotesEach reference number below correlates to a circled numberon the flow chart(s).
1. Use BREAKOUT BOX (Part No. HD-42682) and HAR-NESS CONNECTOR TEST KIT (Part No. HD-41404-B),gray pin probe and patch cord. See 3.12 BREAKOUTBOX: TSM/HFSM.
2. Use HARNESS CONNECTOR TEST KIT (Part No. HD-41404-B), gray socket probe and patch cord.
3. Having the correct multimeter ohm scale is important forthis test. Some meters may read infinity for high ohmvalues. If this is the case, check your ohm scale and retest.

3.23DTC U1016, U1255
GENERALThe serial data connector provides a means for the ElectronicControl Module (ECM), TSM/HFSM and the speedometer tocommunicate their current status. When all operating para-meters on the serial data bus are within specifications, a stateof health message is sent between the components.
A Diagnostic Trouble Code (DTC) U1016 indicates that theECM is not capable of sending this state of health message.A DTC U1255 indicates that no messages were present duringpower up of the current key cycle. A DTC U1016 also indicatesthat there was communication on the data bus since powerup, but communication was lost or interrupted during that keycycle.

3.24DTC U1300, U1301 OR BUS ER
DIAGNOSTICSThe typical serial data voltage range is 0 volts (inactive) to 7volts (active). Due to the short pulse, voltages will be muchlower on a DVOM. In analog mode, a DVOM reading serialdata will show continuous voltage when active, typically 0.6-0.8 volts. The range for acceptable operations is 0-7.0 volts.
Diagnostic Tips• If serial data is shorted, these Diagnostic Trouble Codes
(DTCs) will automatically cause the check engine lamp toilluminate. The odometer will read "BUS Er" in this condi-tion.
• DTCs P1009 and P1010 may accompany DTCs U1300and U1301.
Diagnostic NotesIf a U1300, U1301 or "BUS Er" is present, perform diagnosticprocedures listed in 4.11 STARTS, THEN STALLS.

4.2EFI SYSTEM
GENERALSee Figure 4-1. The engine management system consists ofthe following components:
• Electronic Control Module (ECM).
• Crankshaft Position (CKP) Sensor.
• Manifold Absolute Pressure (MAP) Sensor.
• Intake Air Temperature (IAT) Sensor.
• Engine Coolant Temperature (ECT) Sensor.
• Idle Air Control (IAC).
• Throttle Position (TP) Sensor.
• Vehicle Speed Sensor (VSS).
• Oxygen (O2) Sensor
• Turn Signal Module (TSM) or optional, factory-installedTurn Signal Security Module (TSSM Japan/Korea only)or Hands-Free Security Module (HFSM).This includes anintegrated Bank Angle Sensor (BAS).
• Fan relay.
• Jiffy Stand Sensor (HDI).
• System relay.
• Ignition (plug top) coils.
• Purge solenoid (California models only).
The ECM is mounted ahead of the battery behind the left sidecover. It computes the spark advance for proper ignition timingand fuel control based on sensor inputs (from CKP, MAP, IATand TP sensor) and controls the low-voltage circuits for theignition coils and injectors.
The ECM contains all of the solid state components used inthe ignition system. The dwell time for the ignition coil is alsocalculated in the microprocessor and is dependent upon batteryvoltage. The programmed dwell is an added feature to giveadequate spark at all speeds. (The ECM has added protectionagainst transient voltages, continuous reverse voltage protec-tion, and damage due to jump starts.) The ECM is fullyenclosed to protect it from vibration, dust, water or oil.This unitis a non-repairable item. If it fails, it must be replaced.
The CKP is located on the left front of the lower crankcase half.The CKP generates an AC signal which is sent to the ECMwhere it is used to reference engine position (TDC) and speed.It functions by taking readings off the 22 teeth on the alternatorrotor (two teeth are missing to establish a reference point).
The MAP sensor is located at the rear intake port. The MAPsensor monitors the intake manifold pressure (vacuum) andsends the information to the ECM where the module adjuststhe spark and fuel timing advance curves for optimum perform-ance.
The BAS is within the TSM/TSSM/HFSM. TheTSM/TSSM/HFSM will shut the engine down if the vehicle istipped over. Once the sensor is tripped, the motorcycle mustbe uprighted, turned off and then on again before the enginecan be restarted. This is communicated across the data bus.
Front and rear coils fire each spark plug independently (onecylinder at a time - no wasted spark).The coil also has an extraterminal to monitor current on the coil secondary circuit. Thisis used for knock detection and combustion diagnostics.
The ignition system gives a spark near top dead center forstarting. At RPM and loads above this, the system gives aspark advance that varies between 0 and 50 degreesadvanced.
The IAT, ECT, O2, and TP sensors are used to provideinformation to the ECM to fine tune spark and fuel delivery.The ECT sensor also controls the cooling fan relay to provide12VDC to the fans. The VSS is used as an input for idle speedcontrol.
The O2 sensor Diagnostic Trouble Codes (DTCs) may be seenduring the vehicle break-in period. The O2 sensor DTCs willnot illuminate the check engine lamp for current or historiccodes and will only be indicated by Digital Technician orspeedometer self diagnostics. If the DTCs are reported duringthe break-in period, clear or ignore the codes until the break-in period is completed.
The purge solenoid (California models only) allows vapors fromthe charcoal canister to flow to the throttle body. The timingand amount of solenoid opening depends on engine speed,vehicle speed, engine temperature and throttle position.

4.3DIAGNOSTIC INTRODUCTION
SYSTEM PROBLEMSAll system problems fall into at least one of three general cat-egories.
No StartThe engine cranks over freely, but will not start. This does notinclude situations where the engine will not crank, such as asecurity disabled starter, dead battery, etc. This conditionassumes that all obvious checks (fuel in tank, etc.) have beenmade.
Poor PerformanceThe engine starts but there are performance problems. Theseproblems may include poor fuel economy, rough idle, enginemisfire, engine hesitation, severe spark knock, etc.
Check Engine LampSee Figure 4-2.The check engine lamp indicates the ElectronicControl Module (ECM) has determined a fault condition exists.There may also be starting or performance problems.

RESOLVING PROBLEMSTo resolve system problems, four basic steps are involved. Inorder of occurrence, they are:
1. Check for Diagnostic Trouble Codes (DTCs) by observingcheck engine lamp. See 4.4 CHECKING FOR TROUBLECODES.
2. Diagnose system problems. This involves using specialtools and the diagnostic flow charts.
3. Correct problems through the replacement and/or repairof the affected components.
4. After repairs are performed, the work must be validated.This involves clearing the trouble codes and confirmingproper vehicle operation as indicated by the behavior ofthe check engine lamp.

CUSTOM CD CREATIONS BY REPAIRMANUALSONCD.COM
4.4CHECKING FOR TROUBLE CODES
CHECK ENGINE LAMPTo diagnose system problems, start by observing the behaviorof the check engine lamp.
NOTES
• See Figure 4-3. "Key ON" means that the Ignition Switchis turned to IGN and the Engine Stop Switch is set to RUN(although the engine is not running).
• When the Ignition Switch is turned ON, the check enginelamp will illuminate for approximately four seconds andthen turn off.
• If the check engine lamp is not illuminated at Key ON orif it fails to turn off after the initial four-second period, thenthe instrument module may need to be replaced. See4.5 INSTRUMENT MODULE (IM) SELF DIAGNOSTICS.
1. See Figure 4-4. After lamp turns off after being illuminatedfor the first four-second period, one of three situations mayoccur.
a. The lamp remains off. This indicates there are nocurrent fault conditions or stored DTCs currentlydetected by the Electronic Control Module (ECM).
b. The lamp stays off for only four seconds and thencomes back on for an eight-second period. Thisindicates a code is stored, but no current DTC exists.
c. The lamp remains on beyond the eight-second period.This indicates a current DTC exists.
2. See 4.4 CHECKING FOR TROUBLE CODES, Code Typesfor a complete description of DTC formats.
NOTE
Some DTCs can only be fully diagnosed during actuation. Forexample, a problem with the ignition coil will be considered acurrent fault even after the problem is corrected, since the ECMwill not know of its resolution until after the coil is exercised byvehicle start sequence. In this manner, there may sometimesbe a false indication of the current DTC.

CODE TYPES
TOOL NAMEPART NUMBER
DIGITAL TECHNICIANHD-44750
There are two types of Diagnostic Trouble Codes (DTCs):current and historic. If a DTC is stored, it can be read usingeither a computer-based diagnostic package called DIGITALTECHNICIAN (Part No. HD-44750) or speedometer self dia-gnostics. See 4.5 INSTRUMENT MODULE (IM) SELF DIA-GNOSTICS.
NOTES
• To differentiate between current and historic DTCs, acomputer-based diagnostic package called DIGITALTECHNICIAN (Part No. HD-44750) must be employed.
• All DTCs reside in the memory of the ECM, TSM/TSSM/HFSM, speedometer or tachometer until the DTC iscleared by use of the speedometer self diagnostics. See4.5 INSTRUMENT MODULE (IM) SELF DIAGNOSTICS.
• A historic DTC is also cleared after a total of 50 trips haselapsed. A trip consists of a start and run cycle. After the50 trip retention period, the DTC is automatically erasedfrom memory providing that no subsequent faults of thesame type are detected in that period.
CurrentCurrent DTCs are those which are present during the currentignition cycle. See the appropriate flow charts for solutions.
HistoricIf a particular problem happens to resolve itself, the activestatus problem is dropped and it becomes a historic DTC ratherthan a current DTC.
Historic DTCs can only be retrieved using a computer-baseddiagnostic package called DIGITAL TECHNICIAN (Part No. HD-44750).
Historic DTCs are stored for 50 ignition cycles after any DTCwas last set as current to assist in the diagnosis of intermittentfaults. On the 50th cycle, the DTC will clear itself. The checkengine lamp will not indicate the existence of only historicDTCs.
It is important to note that historic DTCs will exist wheneverthe system indicates the existence of a current fault. See4.4 CHECKING FOR TROUBLE CODES, Multiple DiagnosticTrouble Codes if multiple DTCs are found.
Diagnostic charts are designed for use with current DTCs andas a result they frequently suggest part replacement. Whendiagnosing a historic DTC the charts can be helpful but shouldnot lead to part replacement without verification the part isfaulty.
RETRIEVING DIAGNOSTIC TROUBLECODES
TOOL NAMEPART NUMBER
DIGITAL TECHNICIANHD-44750
The engine management system provides two levels of dia-gnostics.
• The most sophisticated mode employs a computer-baseddiagnostic package called DIGITAL TECHNICIAN (PartNo. HD-44750).
• The second mode requires using the instrument module(IM) self-diagnostics. IM, TSM/TSSM/HFSM and ECMDTCs can be accessed and cleared. See 4.5 INSTRU-MENT MODULE (IM) SELF DIAGNOSTICS for moreinformation.
MULTIPLE DIAGNOSTIC TROUBLE CODESWhile it is possible for more than one fault to occur and setmore than one DTC, there are several conditions which mayresult in one fault setting multiple DTCs:
• The MAP and TP sensors are connected to the same ref-erence line (+5V Vref). If the reference line goes to groundor open, multiple codes will be set (DTC P0107, P0122and P0501).
• Serial data DTCs (U1300, U1301, U1016, U1064, U1096and U1255, ) may be accompanied by other DTCs.Always correct the serial data DTCs before resolving theother DTCs.
Refer to Table 4-8. This table gives most ECM DTCs a priorityranking.

DIAGNOSTICS
Diagnostic Tips• For a quick check of IM function, a "WOW" test can be
performed. See Figure 4-6. Turn Ignition Switch to ACC.Background lighting should illuminate, gauge needlesshould sweep their full range of motion, and indicatorlamps controlled by the serial bus (battery, security,coolant temperature, ABS and check engine) should illu-minate.
• If IM fails "WOW" test, check for battery, ground andaccessory to IM. If any feature in the IM is non-functional,see 2.6 NO IM POWER.
Diagnostic NotesEach reference number below correlates to a circled numberon the flow chart(s).
1. To exit diagnostic mode, turn Ignition Switch OFF.

4.8INITIAL DIAGNOSTIC CHECK
GENERALTo locate faulty circuits or other system problems, follow thediagnostic flow charts in this section. For a systematicapproach, always begin with 2.4 INITIAL DIAGNOSTICCHECK: IM, Initial Diagnostics. Read the general informationand then work your way through the flow chart box by box.
Diagnostic NotesIf a numbered circle appears adjacent to a flow chart box, thenmore information is offered in the diagnostic notes. Many dia-gnostic notes contain supplemental information, descriptionsof various diagnostic tools or references to other parts of themanual where information on the location and removal ofcomponents may be obtained.
Circuit Diagram/Wire Harness ConnectorTableWhen working through a flow chart, refer to the illustrations,the associated circuit diagram and the wire harness connectortable as necessary.The wire harness connector table for eachcircuit diagram identifies the connector number, description,type and general location.
In order to perform most diagnostic routines, a Breakout Boxand a digital volt/ohmmeter (DVOM) are required. See4.6 BREAKOUT BOX: ECM.
To perform the circuit checks with any degree of efficiency, afamiliarity with the various wire connectors is also necessary.
Job/Time Code ValuesDealership technicians filing warranty claims should use thejob/time code values printed in bold text beneath the appro-priate repair.
INITIAL DIAGNOSTICS
General InformationThe diagnostic check is an organized approach to identifyinga problem caused by an electronic control system malfunction.
Diagnostic Tips• If Instrument Module (IM) reads "No Response" with the
Ignition Switch turned ON (Engine Stop Switch at RUNwith the engine off), check data link for an open or shortto ground between data link connector [91A] terminal "3"and ECM, IM or TSM/TSSM/HFSM. See 4.5 INSTRU-MENT MODULE (IM) SELF DIAGNOSTICS.
• Check for an open diagnostic test terminal between dataterminal "3" and ECM. With Ignition Switch turned ON,transmit data should be typically 0.6-0.8 volts. The rangeof acceptable operation is 0-7.0 volts.
• If IM reads "BUS ER" (serial date bus error), refer to flowcharts in 4.11 STARTS, THEN STALLS.
Diagnostic NotesEach reference number below correlates to a circled numberon the flow chart(s).
1. Compare engine behavior to symptoms tables.
a. Starts hard. Refer to Table 4-5.
b. Hesitates, stumbles, surges, misfires and/or sluggishperformance. Refer to Table 4-6.
c. Engine exhaust emits black smoke or fouls plugs.Refer to Table 4-7.
All EFI diagnostic codes are listed in Table 4-8.

Diagnostic NotesEach reference number below correlates to a circled numberon the flow chart(s).
1. Check for DTCs. See 4.4 CHECKING FOR TROUBLECODES, Retrieving Diagnostic Trouble Codes.
2. Check the condition of the battery. Perform a voltage testand recharge if below 12.60V. Check battery connectionsand perform either a conductance test (using ELEC-TRICAL SYSTEM ANALYZER (Part No. MCR-101 HD) )or load test. Replace the battery if necessary. See Batteryin the Service Manual.
3. Typically, when IAC is not functioning, the engine will notstart unless throttle is opened and the engine will stallwhen throttle is closed.
4. See Figure 4-12. Plug IGNITION COIL CIRCUIT TESTADAPTER (Part No. HD-44687) and FUEL INJECTORTEST LAMP (Part No. HD-34730-2C) into Breakout Boxterminals "13" and "11". Start engine. If lamp flashes, noproblem is found. Repeat for Breakout Box terminals "13"and "29".
5. Use HARNESS CONNECTOR TEST KIT (Part No. HD-41404-B), gray terminal probe and patch cord.
6. Connect BREAKOUT BOX (Part No. HD-43876). See4.6 BREAKOUT BOX: ECM.
7. Use HARNESS CONNECTOR TEST KIT (Part No. HD-41404-B), gray terminal probes and patch cords.
Wipe up spilled fuel and dispose of rags in a suitablemanner. An open spark around gasoline could cause afire or explosion, resulting in death or serious injury.(00518b)

4.10NO ECM POWER
GENERAL
No Spark/No Check Engine Lamp at Key OnConstant power is supplied to the ECM through terminal "31".The ECM turns on when power is applied to terminal "13" ofconnector [78]. The ECM goes through an initializationsequence every time power is removed and re-applied to ter-minal "13". The only visible part of this sequence is the checkengine lamp. Upon starting, the check engine lamp will illu-minate for 4 seconds and then (if parameters are normal) goout.
If battery power is absent at ECM terminal "31":
• DTCs cannot be cleared. Tool will show them as clearedbut will be present next time ignition key is cycled.
• ECM cannot be re-flashed.
• Vehicle will start but IAC pintle will not reset at key OFF.Eventually pintle will be out of position causing perform-ance problems.
NOTE
The key ON sequence also activates the idle air control motor.If power from terminal "31" is disrupted (blown fuse, etc.)always turn the key OFF wait 10 seconds then turn the keyON to reset the motor to the default position.

4.12FUEL SYSTEM ELECTRICAL TEST
GENERALWith the Ignition Switch turned to ON and the Engine StopSwitch at RUN, the ECM will energize the system relay tocomplete the circuit to the in-tank fuel pump. It will remain onas long as the engine is cranking or running, and the ECM isreceiving ignition reference pulses from the CKP sensor. Ifthere are no reference pulses, the ECM will de-energize thesystem relay within 2 seconds after ignition is turned on or theengine has stalled, or immediately after the ignition is shut off.
The fuel pump delivers fuel to the injectors then to the pressureregulator.The regulator controls system pressure. Excess fuelflow is returned to the fuel tank through the pressure regulator.
See Figure 4-22. When the engine is stopped, the pump canbe turned on by applying battery voltage to terminal "1" andground to terminal "3" of the fuel pump connector [141A]. Thefuel pump connector is located on top of the fuel tank.
Improper fuel system pressure may contribute to one or all ofthe following symptoms:
• Engine cranks, but will not run.
• Engine cuts out (may feel like ignition problems).
• Hesitation, loss of power and poor fuel economy.
NOTE
After turning ignition off, you must wait 10 seconds beforeturning the ignition back on to get the fuel pump to reprime.This time-out period is necessary for the fuel pump and IACto reset.

4.15FUEL PRESSURE TEST
GENERALThe fuel pump is located in the fuel tank. It delivers fuel to thefuel metering assembly. The fuel metering assembly containsthe fuel injectors and the pressure regulator, where the systempressure is controlled. Excess fuel pressure is returned to thefuel tank by a return line. The ECM controls the system relaysupplying 12V to the fuel pump.
When the engine is stopped, the pump can be turned on byapplying battery voltage to terminal "B" and ground to terminal"D" of the fuel pump connector [86A].
Improper fuel system pressure may contribute to one of thefollowing conditions:
• Cranks, but won't run.
• Cuts out (may feel like ignition problem).
• Hesitation, loss of power, or poor fuel economy.

5. See Figure 4-31. Remove protective cap from Schradervalve in fuel metering assembly.
6. Verify that the fuel valve and air bleed petcock on theFUEL PRESSURE GAUGE (Part No. HD-41182) areclosed.
7. Connect fuel pressure gauge to Schrader valve. Reconnectconnector [86].
8. Start and idle engine to pressurize the fuel system. Openthe fuel valve to allow the flow of fuel down the hose ofthe pressure gauge.
9. Position the clear air bleed tube in a suitable containerand open and close the air bleed petcock to purge thegauge and hose of air. Repeat this step several times untilonly solid fuel (without bubbles) flows from the air bleedtube. Close the petcock.
10. Open and close throttle to change engine speed. Note thereading of the pressure gauge. Fuel pressure shouldremain steady at 55-62 psi (380-425 kPa).
11. Turn the engine off. Open the air bleed petcock to relievethe fuel system pressure and purge the pressure gaugeof gasoline.
Gasoline can drain from quick-connect fitting whenremoving fuel line. Gasoline is extremely flammable andhighly explosive, which could result in death or seriousinjury. Wipe up spilled fuel immediately and dispose ofrags in a suitable manner. (00267a)

4.16IDLE AIR CONTROL
GENERAL
TOOL NAMEPART NUMBER
DIGITAL TECHNICIANHD-44750
IAC OperationThe ECM controls engine idle speed by moving the IACto openor close a passage around the throttle plates. It does this bysending voltage pulses to the proper motor winding of the IAC.This causes the pintle to move in or out of the IAC a givendistance for each pulse received.
• To increase idle speed, the ECM retracts the pintle,allowing more air to flow through the throttle body.
• To decrease idle speed, the ECM extends the pintle,allowing less air to flow through the throttle body.
The IAC position can be measured in steps. This can only bedone by using DIGITAL TECHNICIAN (Part No. HD-44750).
• A high number of steps represents a fully retracted pintleand open passage around throttle plate. This correlateswith an increase in the amount of air flowing through thethrottle body.
• Zero steps represents a fully extended pintle. A zeroreading indicates an abnormal condition in which the pintlehas been fully extended and has consequently closed thepassage around throttle plate.
Each time the ignition is turned off, the ECM resets the IAC bysending enough pulses to extend the pintle and effectivelyclose the throttle body. The fully extended value is the ECMreference point. A given number of steps are then calculatedby the ECM for use in setting the proper idle speed and IACposition.
NOTE
Idle speed is controlled by the ECM and cannot be adjusted.
Diagnostic Trouble Code P0505: Loss ofIdle Speed ControlLoss of idle speed control will result if the idle RPM is ±200from preset idle speed and IAC motor is at zero or maximumfor greater than 5 seconds. This DTC may occur with others
for a multiple code situation. Resolve the other codes first tocorrect.

DIAGNOSTICS
TOOL NAMEPART NUMBER
HARNESS CONNECTOR TEST KITHD-41404-B
BREAKOUT BOXHD-43876
Diagnostic TipsEngine idle speed can be adversely affected by the following:
• A loss of idle speed control does not necessarily imply theIAC actuator or wiring has failed. It can be caused by anumber of conditions such as an intake air leak, improperlyadjusted throttle linkage or a misfiring cylinder.
• Leaking injectors will cause fuel imbalance and poor idlequality due to different air/fuel ratios in each cylinder. Tocheck for leaky injectors, first remove the airbox and airfilter. See Airbox and Filter in the Service Manual. Then,with the throttle wide open, turn key ON for 2 seconds andthen OFF for 2 seconds five consecutive times. Replacethe fuel injector if there is any evidence of raw fuel in thebores. See Fuel Injectors in the Service Manual.
• Vacuum leaks. To check for vacuum leaks, spray wateraround the throttle body seals while idling the engine. IfRPM changes, replace seals.
• Contaminated fuel.
• TPS reading of greater than 1% (possible throttle cablemisadjustment) or battery voltage reading of less than 9volts or a Vehicle Speed Sensor (VSS) greater than 0 willdisable idle speed control.
• If there is a loss of battery power at ECM terminal "31",vehicle will start but IAC pintle will not reset at key OFF.Eventually pintle will be out of position causing perform-ance problems.
Diagnostic NotesEach reference number below correlates to a circled numberon the flow chart(s).
1. When the engine is stopped, the IAC pintle extends andthen retracts to a fixed "Park" position for increased airflowand idle speed during the next engine start sequence.Thiskey OFF reset procedure takes 10 seconds to perform.
2. Test lamp behavior may follow two patterns. The color ofthe lights is not relevant to IAC operation.
a. Normal behavior: At key ON, test lights will alternatelyflash and then remain steady on to confirm ECM sig-nals. At key OFF lights alternately flash and go outafter 10 second reset procedure.
b. Problem indicated: One or more lights fail to illuminateduring key ON/key OFF cycle.

CUSTOM CD CREATIONS BY REPAIRMANUALSONCD.COM
NOTEThere is a remote possibility that one of the circuits is shortedto voltage which would have been indicated by a steady light.Disconnect ECM and turn the ignition ON. Probe terminals tocheck for this condition.
3. Connect BREAKOUT BOX (Part No. HD-43876) to EFIwire harness only, leaving ECM disconnected. See4.6 BREAKOUT BOX: ECM.
4. Use HARNESS CONNECTOR TEST KIT (Part No. HD-41404-B) , purple terminal probe and patch cord.
5. Repair faulty ECM connection or replace ECM. If ECMrequires replacement, see ECM in the Service Manual.

GENERAL
IAT SensorThe ECM supplies and monitors a voltage signal terminal "7"to one side of the Intake Air Temperature (IAT) sensor. Theother side of the IAT sensor is connected to a common sensorground, which is also connected to the ECM terminal "26".
The IAT sensor is a thermistor device, meaning that at a spe-cific temperature, it will have a specific resistance across itsterminals. As this resistance varies, so does the voltage atterminal "7".
• At high temperatures, the resistance of the sensor is verylow, which effectively lowers the signal voltage on terminal"7".
• At low temperatures, the resistance is very high, allowingthe voltage to rise close to 5 volts.
The ECM monitors this voltage to compensate for variousoperating conditions.

Diagnostic TipsAn intermittent may be caused by a poor connection, rubbedthrough wire insulation or a wire broken inside the insulation.
Check the following conditions:
• Poor connection: Inspect ECM and harness connector[78] for backed out terminals, improper mating, brokenlocks, improperly formed or damaged terminals, poor ter-minal- to-wire connection and damaged harness.
• Perform 4.7 WIGGLE TEST to locate intermittents: Ifconnections and harness check out OK, use a DVOM tocheck the intake air temperature sensor voltage whilemoving related connectors and wiring harness. If the failureis induced, the intake air temperature display will change.
• Shifted sensor: Refer to Table 4-29. This table may beused to test the intake air temperature sensor at varioustemperature levels in order to evaluate the possibility of ashifted (out-of-calibration) sensor which may result indriveability problems.
NOTE
All voltage and resistance values are approximate (±20%).Measure IAT sensor resistance between ECM terminal "7" andsystem ground (ECM terminal "26").
Diagnostic NotesEach reference number below correlates to a circled numberon the flow chart(s).

GENERAL
ECT SensorThe ECM supplies and monitors a voltage signal terminal "6"to one side of the Engine Coolant Temperature (ECT) sensor.The other side of the ECT sensor is connected to a commonsensor ground, which is also connected to the ECM terminal"26".
The ECT sensor is a thermistor device, which means that at aspecific temperature it will have a specific resistance acrossits terminals. As this resistance varies, so does the voltage onterminal "6".
• At high temperatures, the resistance of the sensor is verylow, which effectively lowers the signal voltage on terminal"6".
• At low temperatures, the resistance is very high, allowingthe voltage to rise close to 5 volts.
The ECM monitors this voltage to compensate for variousoperating conditions. The ECM also uses the sensor input asa reference for determining IAC pintle position.

Diagnostic TipsOnce the engine is started, the temperature should rise steadily.
An intermittent may be caused by a poor connection, rubbedthrough wire insulation or a wire broken inside the insulation.
Check the following conditions:
• Poor connection: Inspect ECM harness connector [78]for backed out terminals, improper mating, broken locks,improperly formed or damaged terminals, poor terminal-to-wire connection and damaged harness.
• Perform 4.7 WIGGLE TEST to locate intermittents: Ifconnections and harness check out OK, use a DVOM tocheck the engine temperature reading while moving relatedconnectors and wiring harness. If the failure is induced,the engine coolant temperature display will change.
• Shifted sensor: Refer to Table 4-32. This table may beused to test the Engine Temperature (ET) sensor at
various temperature levels in order to evaluate the possib-ility of a shifted (out-of-calibration) sensor which may resultin driveability problems.
NOTE
All voltage and resistance values are approximate (±20%).Measure ECT sensor resistance between ECM terminal "6"and system ground ECM terminal "26".
Diagnostic NotesEach reference number below correlates to a circled numberon the flow chart(s).
1. Connect BREAKOUT BOX (Part No. HD-43876) to EFIwire harness only (leave ECM disconnected). See4.6 BREAKOUT BOX: ECM.
2. If engine has not been operated for 1 hour, the measuredresistance should be very close to the measured resist-ance across the IAT sensor which is terminals "7" and"26" on the Breakout Box.
3. Use HARNESS CONNECTOR TEST KIT (Part No. HD-41404-B), purple terminal probes and patch cords.
4. Use HARNESS CONNECTOR TEST KIT (Part No. HD-41404-B), gray socket probes and patch cords.
5. Replace ECT sensor. See the Service Manual.

GENERAL
TP SensorThe ECM supplies a 5 volt signal terminal "14" to the ThrottlePosition (TP) sensor. The TP sensor sends a signal back tothe ECM terminal "24". The returned signal varies in voltageaccording to throttle position.
• At idle (closed throttle), the signal is typically in the rangeof 0.20-0.80 volts.
• At wide open throttle, the signal is normally 4.0-4.9 volts.
DTC P0122 or P0123 will set if the TP sensor voltage signaldoes not fall within the acceptable range.

DIAGNOSTICS
TOOL NAMEPART NUMBER
HARNESS CONNECTOR TEST KITHD-41404-B
BREAKOUT BOXHD-43876
Diagnostic TipsThe DVOM reads throttle position in volts. Voltage shouldincrease at a steady rate as the throttle is moved from idle towide open. A short to ground or open on the (GY/V) or (R/W)wires also will result in a DTC P0122. A short to ground or openon the (R/W) wire (+5V REF) sets multiple codes as describedbelow.
NOTE
The MAP and TP sensors are both connected to the samereference line (+5V Vref). If the line goes to ground or open,
multiple trouble codes will be set (DTCs P0107, P0108 andP0122, P0123, P1501, or P1502.) Start with the DTC havingthe lowest ranking value.
Check for the following conditions:
• Poor Connection: Inspect ECM harness connector [78B]for backed out terminals, improper mating, broken locks,improperly formed or damaged terminals, poor terminal-to-wire connection and damaged harness.
• Perform 4.7 WIGGLE TEST to locate intermittents: Ifconnections and harness check out OK, monitor TP sensorvoltage using a DVOM while moving related connectorsand wiring harness. If the failure is induced, the TP sensorvoltage will change.
• TP sensor scaling: Observe the TP sensor voltage dis-play while opening the throttle with engine stopped andignition switch ON. Display should vary from closed throttleTP sensor voltage (when throttle is closed) to greater than4.0 volts (when throttle is held wide open). As the throttleis slowly moved, the voltage should change graduallywithout spikes or low voltages being observed.
Diagnostic NotesEach reference number below correlates to a circled numberon the flow chart(s).
1. Connect a BREAKOUT BOX (Part No. HD-43876) betweenEFI wire harness and ECM before measuring voltage. See4.6 BREAKOUT BOX: ECM. If using a DVOM to measurevoltage, take reading across terminals "24" (positive lead)and "26" (negative lead) on Breakout Box.
2. Replace TP sensor. See the Service Manual.
3. Use HARNESS CONNECTOR TEST KIT (Part No. HD-41404-B), purple terminal probes and patch cords.

Diagnostic TipsO2 Sensor diagnostic codes may be seen during the vehiclebreak-in period. The O2 Sensor DTCs will not illuminate thecheck engine lamp for current or historic codes and will onlybe indicated by DIGITAL TECHNICIAN (Part No. HD-44750)or IM self-diagnostics. If the DTCs are reported during thebreak-in period, clear or ignore the codes until the break-inperiod is completed. All historic O2 Sensor DTCs are to beignored and cleared.
The DVOM displays the signal from the O2 Sensor in volts.This voltage will have an average value tending towards lean,rich or ideal value depending on operating temperature of theengine, engine speed and throttle position. An open/short tovoltage or short to ground in the (PK/O) wire (front) and(PK/GN) wire (rear) will cause the engine to run rich (short toground) or lean (short to voltage) until fault is detected. Oncefault is detected, vehicle will run in open loop.
Check for the following conditions:
• Poor Connection: Inspect the ECM [78], fuel injector [84,85] and O2 Sensor connectors for backed out terminals,improper mating, broken locks, improperly formed ordamaged terminals, poor terminal-to-wire connection anddamaged harnesses.
• Dirty/stuck open injectors: The vehicle may run lean(dirty/clogged injectors) or rich (stuck open injectors) ifthere are injector problems. This could also cause poorfuel economy and performance.
• Loose O2Sensor: If an O2 Sensor is loose, engine per-formance may be affected. This could also show up as aslow changing O2 Sensor voltage.
• Loose/leaking exhaust: This can cause a poor groundconnection for the sensor or allow fresh air into the exhaustsystem. If fresh air enters exhaust system, the O2 Sensorwill read a lean condition, causing the system to go rich.
• Engine misfire: See 4.6 BREAKOUT BOX: ECM
Diagnostic NotesEach reference number below correlates to a circled numberon the flow chart(s).
1. Connect a BREAKOUT BOX (Part No. HD-48637) betweenwire harness and ECM before measuring voltage. See4.6 BREAKOUT BOX: ECM
2. 5 volts is typical for a cold engine. Once the O2 Sensorsare up to operating temperature, typical voltage is 0.45volt.

Fuel InjectorsThe fuel injectors are solenoids that allow pressurized fuel intothe intake tract.The injectors are timed to the engine cycle andtriggered sequentially. The power for the injectors comes fromthe system relay. The system relay also provides power forthe fuel pump and the ignition coil.The ECM provides the pathto ground to trigger the injectors.
NOTE
ECM fuse and system relay failures or wiring harness problemswill cause 12 volt power to be lost to both injectors, ignitioncoils and fuel pump.

GENERAL
Ignition CoilIgnition coil DTCs will set if the ignition coil primary voltage isout of range. This could occur if there is an open coil or lossof power to the coil. If front and rear DTCs are set simultan-eously, it is likely a coil power failure or a coil failure.
The coil receives power from the system relay at the sametime that the fuel pump and injectors are activated.The systemrelay is active for the first 2 seconds after the ignition switch isturned ON and then shuts off until RPM is detected from theCKP sensor, at which time it is reactivated. The ECM isresponsible for turning on the system relay by providing theground to activate the relay, which in turn powers the coil.

GENERAL
Jiffy Stand Sensor (HDI)The Jiffy Stand Sensor utilizes a Hall-effect sensor to monitorJiffy Stand position. When the Jiffy Stand is fully retracted thesensor picks up the presence of the metal tab mounted to theJiffy Stand. The metal tab is moved away from the sensor asthe Jiffy Stand is extended. When the Jiffy Stand is extendedthe engine will only start and run if the TSM/TSSM/HFSMdetermines the transmission is in neutral. Otherwise the enginewill start and stall.This is done by monitoring the neutral switchinput to the TSM/TSSM/HFSM and communicating that inputover the serial data circuit to the Electronic Control Module(ECM).
See Figure 4-69. The Jiffy Stand Sensor is powered andmonitored by the ECM. The ECM terminal "14" supplies the5V reference to the Jiffy Stand Sensor connector [133] terminal"1". The Jiffy Stand Sensor terminal "2" sends a signal backto the ECM terminal "9". This signal is used by the ECM todetermine when the Jiffy Stand is retracted or extended. TheJiffy Stand Sensor terminal "3" is grounded through the ECMterminal "28".
The Jiffy Stand Sensor also has a Fail Enable Mode.This modeallows the engine to start and run if the system recognizes aproblem with the Jiffy Stand Sensor circuit. When a problemexists or if the transmission is put in gear with the Jiffy Standextended the odometer will display "SIdE Stand." DTC P1501or P1502 will set if the Jiffy Stand Sensor circuits are out ofrange.

5.1ANTILOCK BRAKE SYSTEM (ABS) GENERALINFORMATION
ANTILOCK BRAKE SYSTEM (ABS)DESCRIPTION
Antilock Brake System (ABS)The Antilock Brake System (ABS) module controls brakeapplication under extreme stopping conditions in order to keepthe wheels from slipping. When wheel slip is detected duringa brake application, an ABS event occurs. The hydraulicpressure to the individual wheel is controlled to prevent slippingon that wheel. Specific valves and individual hydraulic linesare provided for each wheel. The ABS can decrease, hold, orincrease fluid pressure to each brake. However, the ABScannot increase hydraulic pressure above the pressure beingtransmitted by the master cylinder.
During an ABS event, a series of rapid pulsations may be feltin either the front brake lever or rear brake pedal. Thesepulsations are caused by the rapid changes in position of theindividual solenoid valves as the ABS responds to wheel speedsensor inputs and attempts to prevent wheel slip. Thesepulsations are present only during initialization and antilockbraking. The pulsations stop when normal braking is resumedor when the vehicle comes to a stop. A ticking or popping noisemay also be heard as the solenoid valves cycle rapidly. Duringantilock braking on dry pavement intermittent chirping noisesmay be heard as the tires approach slipping.These noises andpulsations are considered normal during antilock operation.
Vehicles equipped with ABS may be stopped by applyingnormal force to the brake pedal or lever. Brake operation duringnormal braking is no different then that of previous non-ABSsystems. Maintaining a constant force on the brake pedal orlever provides the shortest stopping distance while maintainingvehicle stability.
In addition to the normal brake system, the Antilock BrakeSystem consists of the following components.
• See Figure 5-1. Electronic Control Unit (ECU): The ECUcontains the motor relay, valve relay, system enable relay,and the solenoids.
• See Figure 5-1. Hydraulic Control Unit (HCU): The HCUcontains the four valves (an apply valve and release valvefor each wheel), two pumps, pump motor, and accumu-lators.
• See Figure 5-2. Front Wheel Speed Sensor.
• See Figure 5-3. Rear Wheel Speed Sensor.
• See Figure 5-4. ABS Diode Pack.
When referencing the ECU and the HCU as a unit they arereferred to as the Antilock Brake System (ABS) module.

Figure 5-4. ABS Diode Pack
Pressure HoldThe ECU closes the apply valve and keeps the release valveclosed in order to isolate the slipping wheel when wheel slipoccurs. This holds the pressure steady on the brake so thatthe hydraulic pressure does not increase or decrease.
Pressure DecreaseIf a pressure hold does not correct the wheel slip condition, apressure decrease occurs. The apply valve is closed and therelease valve is opened. The excess fluid is stored in the
accumulator until the pump can return the fluid to the mastercylinder or fluid reservoir.
Pressure IncreaseAfter the wheel slip is corrected, a pressure increase occurs.The ECU increases the pressure to individual wheels duringdeceleration in order to reduce the speed of the wheel. Theapply valve is opened and the release valve is closed. Theincreased pressure is delivered from the master cylinder andwill not exceed the pressure from the master cylinder.
Initialization Self-TestThe ABS module performs one initialization test each ignitioncycle.The ABS module verifies internal circuitry and the wheelspeed sensor circuits.
As part of the initialization self test the ABS module also doesa modular test. This test consists of energizing the actuators,and commanding the motor and solenoids on and off.The ABSmodule will run this test the first time the vehicle speed exceeds16 km/h (10 MPH) in an ignition cycle or when all the followingconditions are met for the first time in an ignition cycle:
• Brake switch is not applied.
• Engine is above 500 RPM.
• No ABS event present.
• The system ECU is enabled.
• The ABS system is not communicating with Digital Tech-nician.
ABS IndicatorSee Figure 5-5. The Instrument Module (IM) illuminates theABS indicator when the following occurs.
• The ECU detects an ABS disabling malfunction.The ECUsends a serial data message to the instrument requestingillumination.
• The IM performs a bulb check.
• The IM detects a loss of communication with the ECU.
The ECU sends a message to the instrument when a malfunc-tion that disables ABS operation is detected. Depending onthe fault the ABS Indicator may stay on even after the malfunc-tion is corrected. The indicator will not go off until the vehicleis operated at speeds greater than 16 km/h (10 MPH). It isimportant to verify that this is not the cause of an ABS indicatorwhich is illuminated when no DTCs are set, before attemptingto diagnose other possible causes.

CODE TYPES
TOOL NAMEPART NUMBER
DIGITAL TECHNICIANHD-44750
There are two types of DTCs: current and historic. If a DTC isstored, it can be read using either a computer based diagnosticpackage called DIGITAL TECHNICIAN (Part No. HD-44750)or IM Self Diagnostics. See 5.2 INSTRUMENT MODULE (IM)SELF DIAGNOSTICS.
Trouble codes reside in the memory of the IM, ECM,TSM/TSSM/HFSM, or ABS (if equipped) until the code iscleared by use of the Instrument Module or a total of 50 tripshas elapsed. A trip consists of a start and run cycle, the runcycle lasting at least 5 seconds. After the 50 trip retentionperiod, the trouble code is automatically erased from memoryproviding that no subsequent faults of the same type aredetected in that period.
CurrentCurrent DTCs are those which are present during the currentignition cycle. See the appropriate flow charts for solutions.
HistoricIf a particular problem happens to resolve itself, the activestatus problem is dropped and it becomes a historic DTC ratherthan a current DTC.
Historic DTCs are stored for 50 ignition cycles after any DTCwas last set as current to assist in the diagnosis of intermittentfaults. On TSM models, the check engine lamp will also indicatethe existence of historic codes for one ignition cycle.
It is important to note that historic DTCs may also be presentwhenever the system indicates the existence of a current fault.See 5.1 ANTILOCK BRAKE SYSTEM (ABS) GENERALINFORMATION, Multiple Trouble Codes if multiple DTCs arefound.
Diagnostic charts are designed for use with current DTCs andas a result they frequently suggest wire repair or part replace-ment.When diagnosing a historic DTC the charts can be helpfulbut should not lead to part replacement without verification thepart is faulty.
RETRIEVING DIAGNOSTIC TROUBLECODES
TOOL NAMEPART NUMBER
DIGITAL TECHNICIANHD-44750
There are two levels of diagnostics.
• The most sophisticated mode uses a computer-baseddiagnostic package called the DIGITAL TECHNICIAN (PartNo. HD-44750)
• The second mode requires using Instrument Module (IM)Self Diagnostics. IM, TSM/TSSM/HFSM, ABS, and ECMcodes can be accessed and cleared. See 5.2 INSTRU-MENT MODULE (IM) SELF DIAGNOSTICS for moreinformation.
MULTIPLE TROUBLE CODESWhile it is possible for more than one fault to occur and setmore than one DTC, there are several conditions which mayresult in one fault setting multipleDTCs:
Serial data codes (DTC U1300, U1301, U1016, U1097 andU1098) may be accompanied by other codes. Always correctthe serial data codes before resolving the other codes.

5.4INITIAL DIAGNOSTIC CHECK: ABS
GENERALTo locate faulty circuits or other system problems, follow thediagnostic flow charts and tests in this section. For a systematicapproach, always begin with 5.4 INITIAL DIAGNOSTICCHECK: ABS, Initial Diagnostics. Read the general informationand then work your way through the flow chart box by box.
Diagnostic NotesIf a numbered circle appears adjacent to a flow chart box, thenmore information is offered in the diagnostic notes. Many dia-gnostic notes contain supplemental information, descriptionsof various diagnostic tools or references to other parts of themanual where information on the location and removal ofcomponents may be obtained.
Circuit Diagram/Wire Harness ConnectorTableWhen working through a flow chart, refer to the illustrations,the associated circuit diagram and the wire harness connectortable as necessary.The wire harness connector table for eachcircuit diagram identifies the connector number, description,type and general location.
In order to perform most diagnostic routines, a Breakout Boxand a DVOM are required. See 5.3 BREAKOUT BOX: ABS.
To perform the circuit checks with any degree of efficiency, afamiliarity with the various wire connectors is also necessary.
Job/Time Code ValuesDealership technicians filing warranty claims should use thejob/time code values printed in bold text underneath theappropriate repair.
INITIAL DIAGNOSTICS
Diagnostic Tips• If Instrument Module (IM) reads "No Response" with the
Ignition Switch turned to ACC (Engine Stop Switch at RUNwith the engine off), check data link for an open or shortto ground between data link connector [91A] terminal "3"and ECM, TSM/TSSM/HFSM, IM, tachometer, or ABSModule (if equipped) connector. See 3.10 INITIAL DIA-GNOSTIC CHECK.
• Check for an open data test terminal between data linkconnector [91A] terminal "3" and ECM.With Ignition Switchturned to ACC, serial data bus voltage should be typically0.6-0.8 volts. The range of acceptable operation is 0-7.0volts.
• If IM reads "BUS Er" (serial data bus error), refer to flowcharts in 4.2 EFI SYSTEM.

DTC C1025, C1027, C1206, C1208: WHEELSPEED SIGNAL INTERMITTENT ORFREQUENCY OUT OF RANGE
TOOL NAMEPART NUMBER
BREAKOUT BOXHD-48642
Circuit DescriptionThe active wheel speed sensor is supplied system voltage fromthe ABS module. The sensor then returns a 7 milliamp or 14milliamp signal back to the ABS module.
Conditions for Running the DTC• Ignition voltage is greater than 6.5V.
• The brake is not depressed.
• There are no front or rear wheel speed sensor circuitmalfunctions.
Conditions for Setting the DTCThe DTC will set if the following conditions exist.
• The ABS module detects a rapid variation in the wheelspeed. The wheel speed changes by 20 km/h (12 MPH)or more in 0.01 second. The change must occur 3 timeswith no more than 0.2 seconds between occurrences.
• The frequency of the wheel speed input goes above2.5kHz for 20 milliseconds.
Action Taken When the DTC Sets• The ABS module disables the ABS.
• The ABS indicator is illuminated.
Conditions for Clearing the DTCThe condition for the DTC is no longer present and the DTChas been cleared with either a "WOW" test or Digital Techni-cian.
The ABS module automatically clears the historic DTC whena current DTC is not detected in 50 consecutive drive cycles.
Diagnostic TipsThe following conditions are possible causes for this fault:
• External or internal wheel speed circuit intermittent open.
• Mismatched or improperly sized tires.
• Electrical noise on the wheel speed wires.
• Worn suspension components.
• Rough terrain.
If the fault only occurs in moist conditions (rain, snow, vehiclewash, etc.) inspect the wheel speed sensor and wiring for signsof water intrusion.
Diagnostic NotesEach reference number below correlates to a circled numberon the flow chart(s).
1. A possible cause of the DTC is electrical noise on thewheel speed sensor harness wiring. Electrical noise couldresult from the wheel speed sensor wires being routed toclose to high energy ignition system components, suchas spark plug wires.
2. Connect BREAKOUT BOX (Part No. HD-48642) betweenwire harness connector [166B] and ABS connector [166A].

DIAGNOSTICSThe typical serial data voltage range is 0 volts (inactive) to 7volts (active). Due to the short pulse, voltages will be muchlower on a DVOM. In analog mode, a DVOM reading serialdata will show continuous voltage when active, typically 0.6-0.8 volts. The range for acceptable operations is 0-7.0 volts.

5. Release locking bar to lock position of contact. Whencorrectly positioned, the locking bar fits snugly in the spaceat the front of the core crimp tails and the closed side ofthe terminal rests on the outer nest of the crimp tool.
6. Insert wires between crimp tails until ends make contactwith locking bar. Verify that wire is positioned so that widepair of crimp tails squeeze bare wire strands, while thenarrow pair folds over the insulation material.
7. Squeeze handle of crimp tool until tightly closed (4). Toolautomatically opens when the crimping sequence is com-plete.
8. Raise locking bar and barrel holder to remove contact.
Inspecting CrimpsInspect the quality of the core and insulation crimps. Distortionshould be minimal.

GeneralSplice connectors and several OE ring terminal connectorsuse heat shrink covering to seal the connection.
Preparing Wire LeadsNOTE
If adjacent wires are to be spliced, stagger the splices so thatthe sealed splice connectors will not touch each other but arelocated at different positions along the length of the wires.
1. Using a shop gauge, identify the gauge of the wire.
2. Match the wire gauge to a sealed splice connector by colorand part number. Refer to Table A-4.
3. Using a wire stripper, cut and strip a length of insulationoff the wire ends. Refer to Table A-4 for the strip length.

NOTE
If any copper wire strands are cut off of the wire core, trim theend and strip the wire again in a larger gauge stripper.
Splicing Wire LeadsNOTE
See Figure A-49. The connector is crimped twice - one sideand then the other.
1. See Figure A-48. Open the PACKARD CRIMPINGTOOL (Part No. HD-38125-8) ratchet by squeezing thehandles closed.
2. Match the connector color to the wire gauge crimp die inthe jaws and insert one end of the sealed connector.
3. Gently squeeze the handles until the connector is held inthe jaws.
4. See Figure A-49. Feed the stripped end of a wire into theconnector until the wire stops inside the metal insert (1).
5. Squeeze the handles tightly closed to crimp the lead inthe insert (2). The tool automatically opens when thecrimping is complete.
6. Slide the connector to the other half of the metal insert.Insert the stripped wire lead (1) until it stops, and crimpthe lead in the insert (2).
Be sure to follow manufacturer's instructions when usingthe UltraTorch UT-100 or any other radiant heating device.Failure to follow manufacturer's instructions can cause afire, which could result in death or serious injury. (00335a)
• Avoid directing heat toward any fuel system component.Extreme heat can cause fuel ignition/explosion resultingin death or serious injury.
• Avoid directing heat toward any electrical system com-ponent other than the connectors on which heat shrinkwork is being performed.
• Always keep hands away from tool tip area and heat shrinkattachment.
7. Use an ULTRA-TORCH UT-100 (Part No. HD-39969), ora ROBINAIR HEAT GUN (Part No. HD-25070) with aHEAT SHIELD ATTACHMENT (Part No. HD-41183), toheat the connector from the center of the crimp (3) out toeach end.
NOTE
It is acceptable for the splice to rest against the heat shrinktool attachment.
Inspecting SealsSee Figure A-49. Allow the splice to cool and inspect the seal.The insulation should appear smooth and cylindrical. Meltedsealant will have extruded out the ends (4) of the insulation.

C.2FLUID CONVERSIONS
UNITED STATES SYSTEMUnless otherwise specified, all fluid volume measurements inthis Service Manual are expressed in United States (U.S.)units-of-measure. See below:
• 1 pint (U.S.) = 16 fluid ounces (U.S.)
• 1 quart (U.S.) = 2 pints (U.S.) = 32 fl. oz. (U.S.)
• 1 gallon (U.S.) = 4 quarts (U.S.) = 128 fl. oz. (U.S.)
METRIC SYSTEMFluid volume measurements in this Service Manual includethe metric system equivalents. In the metric system, 1 liter (L)= 1,000 milliliters (mL). Should you need to convert from U.S.units-of-measure to metric units-of-measure (or vice versa),refer to the following:
• fluid ounces (U.S.) x 29.574 = milliliters
• pints (U.S.) x 0.473 = liters
• quarts (U.S.) x 0.946 = liters
• gallons (U.S.) x 3.785 = liters
• milliliters x 0.0338 = fluid ounces (U.S.)
• liters x 2.114 = pints (U.S.)
• liters x 1.057 = quarts (U.S.)
• liters x 0.264 = gallons (U.S.)
BRITISH IMPERIAL SYSTEMFluid volume measurements in this Service Manual do notinclude the British Imperial (Imp.) system equivalents. The fol-lowing conversions exist in the British Imperial system:
• 1 pint (Imp.) = 20 fluid ounces (Imp.)
• 1 quart (Imp.) = 2 pints (Imp.)
• 1 gallon (Imp.) = 4 quarts (Imp.)
Although the same unit-of-measure terminology as the U.S.system is used in the British Imperial (Imp.) system, the actualvolume of each British Imperial unit-of-measure differs from itsU.S. counterpart.The U.S. fluid ounce is larger than the BritishImperial fluid ounce. However, the U.S. pint, quart, and gallonare smaller than the British Imperial pint, quart, and gallon,respectively. Should you need to convert from U.S. units toBritish Imperial units (or vice versa), refer to the following:
• fluid ounces (U.S.) x 1.042 = fluid ounces (Imp.)
• pints (U.S.) x 0.833 = pints (Imp.)
• quarts (U.S.) x 0.833 = quarts (Imp.)
• gallons (U.S.) x 0.833 = gallons (Imp.)
• fluid ounces (Imp.) x 0.960 = fluid ounces (U.S.)
• pints (Imp.) x 1.201 = pints (U.S.)
• quarts (Imp.) x 1.201 = quarts (U.S.)
• gallons (Imp.) x 1.201 = gallons (U.S.)

C.3TORQUE CONVERSIONS
UNITED STATES SYSTEMThe U.S. units of torque, foot pounds and inch pounds, areused in this service manual.To convert units, use the followingequations:
• foot pounds (ft-lbs) X 12.00000 = inch pounds (in-lbs).
• inch pounds (in-lbs) X 0.08333 = foot pounds (ft-lbs).
METRIC SYSTEMAll metric torque specifications are written in Newton-meters(Nm). To convert metric to United States units and UnitedStates to metric, use the following equations:
• Newton meters (Nm) X 0.737563 = foot pounds (ft-lbs).
• Newton meters (Nm) X 8.85085 = inch pounds (in-lbs).
• foot pounds (ft-lbs) X 1.35582 = Newton meters (Nm).
• inch pounds (in-lbs) X 0.112985 = Newton meters (Nm).

E.1TSM/TSSM (JAPAN/KOREA) OVERVIEW
GENERAL
TSMThe Turn Signal Module (TSM) has two major functions:
• Control turn signals.
• Serve as Bank Angle Sensor (BAS).
TSSMSee Figure E-1.The optional, factory-installed, Harley-DavidsonFactory Security System (H-DFSS) includes a Turn SignalSecurity Module (TSSM) which provides the same functionsas the TSM, but also includes security and immobilizationfunctions.

ed03023
Figure E-2.TSM/TSSM Location
TROUBLESHOOTINGProblems fall into at least one of five categories:
• Turn signal malfunction.
• Bank angle (engine disable).
• Clutch/neutral interlock (starter enable).
• Security lamp problem.
• Security system malfunction.
To resolve TSM/TSSM problems, four basic steps are involved.In order of occurrence, they are:
1. Retrieve Diagnostic Trouble Codes (DTCs) using instru-ment module self-diagnostics. See E.10 INSTRUMENTMODULE (IM) SELF DIAGNOSTICS.
2. Diagnose system problems. This involves using specialtools and the diagnostic flow charts in this section.
3. Correct problems through the replacement and/or repairof the affected components.
4. After repairs are performed, the work must be validated.This involves clearing the DTCs and confirming propervehicle operation as indicated by the behavior of the turnsignals.

E.2TSM/TSSM FEATURES
GENERALThe Turn Signal Module (TSM) and the Turn Signal SecurityModule (TSSM) provide the following capabilities.
TURN SIGNAL FUNCTIONS
TSSM/TSSM FeaturesSee E.4 TSM/TSSM TURN SIGNAL FUNCTIONS for completedetails.
• Manual turn signal control: Manual activation/deactiva-tion of left and right turn signal flashing sequences.
• Automatic turn signal cancellation: Automatic cancella-tion of left and right turn signal flashing sequences basedon either vehicle speed, vehicle acceleration or turn com-pletion.
• Emergency flashers: Four-way left and right turn signalflashing capability.
• Turn signal lamp diagnostics: Self-diagnostics for shortcircuit and open lamp conditions on both left and right turnsignal systems.
BANK ANGLE FUNCTIONSee E.5 TSM/TSSM BANK ANGLE FUNCTION for completedetails.
• Emergency engine shutdown: Will provide engineshutdown when vehicle is tipped over.
• Emergency outputs disable: Will disable turn signallamps and starter motor when vehicle is tipped over.
CLUTCH/NEUTRAL INTERLOCKFUNCTIONS
TSM/TSSM Features• Disables starter: Disables starter until either the clutch
lever is pulled in or transmission neutral is selected.
• Diagnostics: Provides diagnostics for clutch and neutralswitch faults.
SECURITY ALARM AND IMMOBILIZATIONFUNCTIONS
TSSM FeatureThe following information applies only to motorcycles with thesecurity option (TSSM). See E.6 SECURITY SYSTEMFUNCTIONS: TSSM for more information.
• Remote arming/disarming: See Figure E-4. Owners mayenable and disable security alarm and immobilizationfunctions with a personally carried transmitter. This trans-mitter is referred to as a key fob. Remote arming/dis-arming is a function of the TSSM (Japan/Korea) only.
• Security lamp (key icon): See Figure E-5. A lamp withinthe speedometer face tells the rider if the system is armedor disarmed.
• PIN disarming: If a key fob is not available, the TSSMallows the rider to disable the security alarm and immobil-
ization functions if the rider knows the previously enteredpersonal identification number (PIN).
• Arming/disarming confirmation: When the TSSM isarmed, the system provides visual feedback to the riderby flashing the turn signals and sounding the optionalSmart Siren.
• Auto-arming: Automatically enables the security alarmand immobilization functions within 30 seconds after theIgnition Switch is switched OFF.
NOTE
Motorcycles sold with a TSSM have auto-arming disabled, butit can be activated. See E.3 TSM/TSSM VEHICLE DELIVERY.
• Transport mode: It is possible to arm the security systemwithout enabling the motion detector for one ignition cycle.This allows the vehicle to be moved in an immobilizedstate.
• Starter/ignition disable: If the security alarm andimmobilization functions be triggered by a vehicle securitycondition, the starter and ignition system will be disabled.
• Security system alarm: See Figure E-6. The system willalternately flash the left and right turn signals and soundan optional Security Siren if a vehicle security conditionis detected while the system is armed.

E.3TSM/TSSM VEHICLE DELIVERY
GENERALSetting up a vehicle TSM/TSSM depends on whether thevehicle has a Turn Signal Module (TSM) or the optional securitysystem (TSSM) installed. If a motorcycle is equipped with aTSM, no further configuration is required.
However, if a motorcycle has an optional security system(TSSM) installed, perform the following steps as necessary.
1. Configure TSSM motorcycles by assigning both key fobsto the vehicle. See E.3 TSM/TSSM VEHICLE DELIVERY,Key FOB Assignment: TSSM
2. Configure TSSM motorcycles by entering a PersonalIdentification Number (PIN) picked by the customer. ThePIN allows the customer to operate the system if the keyfob is lost or inoperable. Record this PIN in the Owner'sManual and instruct the customer to carry a copy.
CONFIGURING A TSSMNOTE
Do not forget to enter a Personal Identification Number (PIN)for TSSM motorcycles. If a PIN is not assigned and both keyfobs are lost or damaged while the motorcycle is armed, theTSSM must be replaced.
Changes to TSSM settings are made by a series of program-ming operations involving the ignition key, left/right turn signalswitches and key fob (security systems).
At certain steps in the programming sequence, the motorcyclemay provide confirmation of settings by flashing the turn sig-nals, turn signal indicators and/or security lamp. In addition,when programming a PIN into a TSSM system, the odometerdisplays the PIN to the user and dynamically updates it as thecode is entered or changed.
All programming operations are listed in table format. Followthe numbered steps to configure the system. If a confirmation
response is listed, wait for the confirmation before continuingto the next step. Important information pertaining to certainactions will be found in the NOTES column.
POWER DISRUPTION AND CONFIGURINGThe TSM/TSSM will not enter configuration mode on the firstattempt after battery voltage has been removed from terminal"1". This will occur after any of the following situations:
• Battery disconnect or power drain.
• Battery fuse removal.
• Connecting Breakout Box to TSM/TSSM connector.
Therefore, after all battery reconnects, the configurationsequence must be modified as follows.
1. Set run switch to OFF, cycle ignition/headlamp switchON-OFF-ON-OFF-ON and press left turn signal switchtwice.
2. Repeat step listed above.
3. Continue with configuration sequence listed.
KEY FOB ASSIGNMENT:TSSMRefer to Table E-1 to assign a key fob to a motorcycle equippedwith a TSSM.
The key fob on TSSM motorcycles must be set so it will operatethe alarm system on the vehicle. This assignment must becompleted with no pauses between steps greater than 10seconds. Turn the ignition OFF after all key fobs have beenassigned. The programming mode will also exit after 60seconds has elapsed without detecting any fob sign-up mes-sages or turn signal switch activity.
Two key fobs may be assigned to the TSSM. The first suc-cessful attempt to program a fob will disable all previouslyassigned fobs. If a second fob is to be programmed, it mustbe done in the same programming sequence as the initial fob.

PIN ENTRY:TSSMNOTE
Do not forget to enter a Personal Identification Number (PIN)for TSSM vehicles. If a PIN is not assigned and the key fob islost or damaged while the vehicle is armed, the TSSM mustbe replaced.
The TSSM PIN consists of five digits. Each digit can be anynumber from 1-9. There can be no zeros (0) in the PIN. ThePIN must be used to disarm the security system in case thekey fob becomes unavailable.
Refer to Table E-2 to enter an initial PIN with no PIN previouslyinstalled. The procedure listed uses 3-1-3-1-3 as the desiredPIN.
NOTE
For better security, do not use 3-1-3-1-3 as a PIN. It is shownas an example only.
Decide what five-digit PIN the owner would like to use. Thecode will be programmed using the turn signal switches and
key fob. Keep a record of the PIN in a secure place such asyour wallet or the Owner's Manual.
• When programming the PIN, the security lamp flashes toprovide feedback when entering each digit.The odometeralso displays the PIN and the change dynamically.
• The number of security lamp flashes corresponds to thenumber currently selected for a given digit. Therefore, thelamp may flash 1-9 times depending on the numberentered. The five-digit PIN will change in the odometerwindow and the active digit will blink.
• Press the left turn switch one time to increment each digit.
• Quickly press the key fob button twice to advance to thenext digit.
NOTE
The programming mode exits upon turning the ignition switchto OFF, or if no turn signal switch/key fob button activity occursfor 60 seconds. No data is saved for partial configurationattempts if entering a PIN for the first time. If a PIN has previ-ously been entered, the user can change any digit or group ofdigits.

E.4TSM/TSSM TURN SIGNAL FUNCTIONS
GENERALThe TSM/TSSM turn signal feature has several modes:
• Automatic cancellation.
• Manual cancellation.
• Four-way flashing.
• Diagnostics mode.
The turn signals cannot be activated or deactivated when theIgnition Switch is in the ACC position. The turn signals canonly be activated or deactivated with the Ignition Switch in theIGNITION position.
AUTOMATIC CANCELLATIONPress the left or right turn switch to activate automatic turnsignal cancellation. There is no need to hold the turn switch inwhen approaching the turn. The TSM/TSSM will not cancelthe signal before the turn is actually completed.
• When the directional switch is released, the system startsa 20 count. As long as the vehicle is traveling above 11km/h (7 MPH) he directional will always cancel after 20flashes if the system does not recognize any other input.
• If the vehicle speed drops to 11 km/h (7 MPH) or less,including stopped, the directionals will continue to flash.Counting will resume when vehicle speed reaches 12.9km/h (8 MPH) and will automatically cancel when the counttotal equals 20 as stated above.
• The turn signals will cancel within two seconds upon turncompletion. A sensor inside the TSM/TSSM cancels thesignal after the vehicle has been returned to an uprightposition.
NOTE
The bank angle cancellation function has an automatic calibra-tion feature. Ride the motorcycle for 0.4 km (0.25 mile) atsteady speeds (upright) to calibrate the system. Performanceof bank angle function may not be optimal until this calibrationis performed. This self-calibration is performed automaticallyevery time the vehicle is started and ridden.
MANUAL CANCELLATIONIf you want to stop the turn signals from flashing, briefly depressthe turn signal switch a second time.
If you are signalling to turn in one direction and you depressthe switch for the opposite turn signal, the first signal is can-celled and the opposite side begins flashing.
FOUR-WAY FLASHINGUse the following method to activate the four-way flashers:
1. With the Ignition Switch ON and the security system dis-armed (models with security only), press the left and rightturn signal switches at the same time.
2. Turn the Ignition Switch OFF and arm the security systemif present and desired.The four-way flashers will continuefor two hours.
3. To cancel four-way flashing, disarm the security systemif necessary, turn the Ignition Switch ON and press theleft and right turn signal switches at the same time.
This system allows a stranded vehicle to be left in the four-wayflashing mode and secured until help is found.
If the security system is disarmed while the four-way flashersare active, the lights will flash as follows:
1. TSSM stops four-way flashing mode. Motorcycle sits for1 second with turn signals off.
2. TSSM performs disarming confirmation (1 flash).
3. Motorcycle sits for 1 second with turn signals off.
4. Motorcycle restarts four-way flashing mode.
DIAGNOSTICS MODEThe TSM/TSSM measures the current when the turn signalsare used. If there is a burned out light bulb on one side, theremaining light and the corresponding turn signal indicator flashat double the normal rate starting with the fifth flash.
Other diagnostic conditions monitored include:
• Short circuit in the turn signal wiring.
• Open circuit in the turn signal wiring.
• Stuck turn signal switch.
NOTES
• A stuck turn signal switch will disable the automatic turnsignal cancellation feature.
• If a stuck switch is detected, you must hold the left andright turn signal switches in for more than one second toactivate the four-way flashers.
See E.8 DIAGNOSTIC TROUBLE CODES (DTC) for moreinformation.

E.6SECURITY SYSTEM FUNCTIONS:TSSM
GENERAL
Security System OperationThe TSSM provides security and immobilization functions notfound on the TSM. The TSSM will disable the starter and igni-tion system. Additional functions include the ability to alternatelyflash the left and right turn signals and sound a siren (ifequipped) if a theft attempt is detected.
Conditions that activate the security system when system isarmed include:
• Detecting tampering of the ignition circuit: Turn signalsflash three times, optional siren chirps once and then turnsoff. If the tampering continues, a second warning willactivate after four seconds. Continued tampering will causethe alarm to activate for 30 seconds and then turn off.Thetwo warnings/alarm cycle is repeated for each tamperingincident.
• Detecting vehicle movement: Turn signals flash threetimes, optional siren chirps once and then turns off. If thevehicle is not returned to its original position, a secondwarning will activate after four seconds. If the vehicle isnot returned to its original position, the alarm activates for30 seconds then turns off. The two warnings/alarm cyclemay repeat a maximum of 10 times with a 10 secondpause between alarm cycles.
• Detecting that a battery or ground disconnect hasoccurred while armed: Siren, if installed, activates itsself-alarm mode. Turn signals will not flash.
See E.7 ARMING/DISARMING: TSSM for more information.
NOTE
Always disarm the TSSM before removing or disconnectingthe battery to prevent the siren (if installed) from activating. Ifthe TSSM is in auto-arming mode, you must disarm the systemand disconnect the battery or remove the battery fuse beforethe 30 second arming period expires.
Security System Options:TSSMThe following options are only available on the TSSM unit:alarm sensitivity, auto-arming feature, and storage mode.
Default settings for the TSSM include:
• Solo vehicle configuration.
• Medium motion sensitivity on alarm sensitivity.
• All vehicles are shipped with auto-arming disabled.
• Storage mode set to 10 days.
ALARM SENSITIVITY:TSSM
SensitivityThe TSSM has four sensitivity settings: extremely low, low,medium or high. The selection chosen controls the sensitivityof the security system regarding motion detection.
To set alarm sensitivity, refer to Table E-3.
Transport ModeIt is possible to arm the security system without enabling themotion detector for one ignition cycle. This allows the vehicleto be picked up and moved in an armed state. In this mode,any attempt to hot-wire the vehicle will trigger the securitysystem.
• To enter the transport mode, refer to Table E-4.
• To exit from transport mode and return the system tonormal operation/functions, disarm the system using eitherthe key fob or Personal Identification Number (PIN).
NOTE
Transport mode is especially useful when working on themotorcycle. If it is not used, the alarm will activate under manytypical service activities.

AUTO-ARMING FUNCTION:TSSMAuto-arming causes the system to automatically arm itself (nokey fob needed) within 30 seconds after the Ignition Switch isturned OFF. During this period, the security lamp stays illumin-ated to indicate auto-arming is starting up.
The vehicle may be moved during these 30 seconds withouttriggering the alarm. However, any motion after that period willtrigger the security alarm. Upon expiration of the auto-armingperiod, the turn signals flash twice, the security lamp beginsto flash and the siren (if equipped) chirps twice.
The TSSM allows remote arming via the key fob at any time.However, if the system is remotely disarmed (with the key fob)but the Ignition Switch is not turned ON within 30 seconds, thesystem will rearm itself when auto-arming is enabled.
Japan and Korea motorcycles have auto-arming disabled bydefault. However, the feature may be enabled if the customerdesires.
When auto-arming is disabled, the key fob must be used toarm the security system.To set the auto-arming function, referto Table E-5.

STORAGE MODE:TSSMThe TSSM has a special mode for long term storage. Thismode prevents the security system from draining the batteryafter a period of days (10, 20, 60 or infinite) without any IgnitionSwitch activity.
• If the TSSM is set to infinite, the system will not go intostorage mode.
• Vehicles will enter storage mode whether the securitysystem is armed or disarmed.
• If set to 20 days or greater, the customer must use anapproved trickle charger to keep the battery from dischar-ging.
In storage mode, all alarm functions remain active but thereceiver is shut down and will not respond to the key fob. Thevehicle is immobilized because the starter motor and ElectronicControl Module (ECM) are disabled. When the storage modeis entered, the security lamp stops flashing to conserve power.
To wake up the TSSM from storage mode, the Ignition Switchmust be turned ON. This will trigger a warning/alarm if thesystem was previously armed. You must use the key fob orPIN to disarm the system and stop the alarm.
To set the storage mode preferences, refer to Table E-6.

E.7ARMING/DISARMING:TSSM
GENERALThere are two methods to arm the security system:
• Using the key fob.
• Using auto-arming. See E.6 SECURITY SYSTEMFUNCTIONS: TSSM.
NOTE
The vehicle cannot be armed with the ignition ON.
There are two ways to disarm the system:
• Using the key fob. This method works in all situationsexcept before turning Ignition Switch ON when TSSMstorage mode is activated.
• Using a Personal Identification Number (PIN).
SECURITY LAMPRefer to Table E-7. The security lamp within the speedometerprovides feedback to the rider confirming armed or disarmedstatus.

USING KEY FOB:TSSM
GeneralThe TSSM reception range for the key fob signal depends ona specific receiver pattern.
NOTE
Environmental and geographic conditions may affect signalrange.
Arming the System1. Hold key fob horizontal at waist level.
2. Point key fob at the front of the vehicle.
3. Hold down the key fob button until the system respondswith two turn signal flashes.
Disarming the System1. Hold key fob horizontal at waist level.
2. Point key fob at the front of the vehicle.
3. Quickly press the key fob button twice. The system willrespond with one turn signal flash.
NOTE
Disarming function may require practice. The key fob buttonmust be pressed twice within 1.5 seconds to send the disarmcommand. The action is very similar to double-clicking a com-puter mouse. Light quick taps work best; very hard or very slowtaps are less likely to work.
TroubleshootingIf the key fob button has been pressed numerous times whileaway from the vehicle, the fob may fall out of synchronizationwith the TSSM. If this happens, the TSSM might fail to recog-nize the key fob's commands.
To solve this problem, press and hold the key fob button for10-15 seconds until the security system responds with two turnsignal flashes. After confirmation, you may resume normal foboperation.
USING THE PIN
GeneralThe Personal Identification Number (PIN) consists of five digitsentered using the left and right turn signal switches. Each digitcan be any number from 1-9. The PIN is intended to be usedto disarm the motorcycle in case the key fob becomesunavailable or inoperable.
See E.3 TSM/TSSM VEHICLE DELIVERY to set a PIN.
Disarming the SystemRefer to Table E-8. If you make an error while disarming theTSSM using a PIN, the alarm will activate for 30 seconds afterthe last digit is entered. After a failed attempt, the security lampwill flash once every second for 10 minutes. During this time,the vehicle will not accept any attempt to enter a PIN.

E.8DIAGNOSTIC TROUBLE CODES (DTC)
TSM/TSSMTo diagnose system problems, start by observing the behaviorof the security lamp.
NOTES
• See Figure E-7. "Key ON" means that the Ignition Switchis turned to IGNITION and the Engine Stop Switch is setto RUN (although the engine is not running).
• See Figure E-8. When the Ignition Switch is turned ON,the security lamp will illuminate for approximately fourseconds and then turn off.
• If the security lamp is not illuminated at Key ON or if it failsto turn OFF after the initial four second period, thespeedometer may need to be replaced. SeeE.10 INSTRUMENT MODULE (IM) SELF DIAGNOSTICS.If "BUS Er" is displayed on the odometer, it may take upto twenty seconds for the security lamp to illuminate.
• The security lamp will also light for eight seconds after thebulb check if historic diagnostic trouble codes (DTCs) arepresent. The security lamp will stay illuminated if currentDTCs are set. If a historic DTC is present, the securitylamp will light for 2 ignition cycles or until the DTC iscleared manually.

a. The lamp remains off. This indicates there are nocurrent fault conditions or stored historic DTCs cur-rently detected by the TSSM.
b. The lamp stays off for only four seconds and thenilluminates for an eight-second period. This indicatesa historic DTC is stored, but no current DTC exists.
c. If the lamp remains illuminated beyond the eight-second period, a current DTC exists.

DIGITAL TECHNICIANHD-44750
There are two types of Diagnostic Trouble Codes (DTCs):current and historic. If a DTC is stored, it can be read usingeither a computer based diagnostic package called DIGITALTECHNICIAN (Part No. HD-44750) or instrument module self-diagnostics. See E.10 INSTRUMENT MODULE (IM) SELFDIAGNOSTICS.
NOTES
• To differentiate between current and historic diagnostictrouble codes a computer based diagnostic package calledDIGITAL TECHNICIAN (Part No. HD-44750) must beused.
• All DTCs reside in the memory of the ECM, TSM/TSSM,speedometer or tachometer until the DTC is cleared byuse of the instrument module self-diagnostics. SeeE.10 INSTRUMENT MODULE (IM) SELF DIAGNOSTICS.
• A historic DTC is also cleared after a total of 50 ignitioncycles has elapsed. After the 50 ignition cycles retentionperiod, the DTC is automatically erased from memoryproviding no subsequent faults of the same type aredetected in that period.
CurrentCurrent DTCs are those present during the current ignitioncycle. See the appropriate flow charts for solutions.
HistoricIf a particular problem happens to resolve itself, the activestatus problem is dropped and it becomes a historic DTC ratherthan a current DTC. For example, intermittent output shortscan become typical historic DTCs.
Historic DTCs can only be retrieved using a computer baseddiagnostic package called DIGITAL TECHNICIAN (Part No. HD-44750).
Historic DTCs are stored for 50 ignition cycles after any DTCwas last set as current to assist in diagnosing intermittent faults.On the 50th cycle, the DTC will clear itself. The security lampwill indicate the existence of only historic DTCs for just twoignition cycles.
It is important to note that historic DTCs will exist wheneverthe system indicates the existence of a current fault. SeeE.8 DIAGNOSTIC TROUBLE CODES (DTC), Multiple Dia-gnostic Trouble Codes if multiple DTCs are found.
Diagnostic charts are designed for use with current DTCs andas a result they frequently suggest part replacement. Whendiagnosing a historic DTC the charts can be helpful but shouldnot lead to part replacement without verifying the part is faulty.

TOOL NAMEPART NUMBER
DIGITAL TECHNICIANHD-44750
To locate faulty circuits or other system problems, follow thediagnostic flow charts. For a systematic approach, always beginwith E.9 INITIAL DIAGNOSTIC CHECK: TSM/TSSM, InitialDiagnostics. Read the general information and then work yourway through the flow chart box by box.
Diagnostic NotesIf a numbered circle appears adjacent to a flow chart box, thenmore information is offered in the diagnostic notes. Many dia-gnostic notes contain supplemental information, descriptionsof various diagnostic tools or references to other parts of themanual where information on the location and removal ofcomponents may be obtained.
Circuit Diagram/Wire Harness ConnectorTableWhen working through a flow chart, refer to the illustrations,the associated circuit diagram and the wire harness connectortable as necessary.The wire harness connector table for eachcircuit diagram identifies the connector number, description,type and general location.
In order to perform most diagnostic routines, a Breakout Boxand a digital volt/ohmmeter (DVOM) are required. SeeE.11 BREAKOUT BOX: TSM/TSSM.
To perform the circuit checks with any degree of efficiency, afamiliarity with the various wire connectors is also necessary.
Job/Time Code ValuesSome charts may contain warranty job/time codes. Dealershiptechnicians filing warranty claims should use the job/time codevalues printed in bold text underneath the appropriate repair.
Reprogramming ECMDiagnostic charts frequently suggest Electronic Control Module(ECM) replacement. In the event an ECM needs to be replaced,it must be reprogrammed using a computer-based diagnosticpackage called DIGITAL TECHNICIAN (Part No. HD-44750).See your dealer. Password learn procedure must also be per-formed. See 3.25 TSM/HFSM: PASSWORD LEARN.
INITIAL DIAGNOSTICS
Diagnostic Tips• If odometer reads "BUS Er" with the Ignition Switch turned
ON (Engine Stop Switch at RUN with the engine off), checkdata bus for an open or short to ground between data linkconnector [91A] terminal "3" and ECM connector [78B]terminal "5", TSSM connector [30B] terminal "3", speedo-meter connector [39B] terminal "2" or tachometer (ifequipped) connector [108B] terminal "2".
• Check for an open diagnostic test terminal between datalink connector [91A] terminal "3" and TSM/TSSM connector[30B] terminal "3". With Ignition Switch turned ON, serialdata bus voltage should be typically 0.6-0.8 volt.The rangeof acceptable voltage is 0-7.0 volts.
• To identify intermittents, wiggle vehicle harness whileperforming steps in the Diagnostic Check charts.
Diagnostic NotesEach reference number below correlates to a circled numberon the flow chart(s).
1. Compare TSM/TSSM system behavior to symptoms inTable E-10.
All TSM/TSSM diagnostic trouble codes (DTCs) are listed inTable E-9.

E.12FAILS TO DISARM
GENERAL
Security Equipped Vehicles OnlyThis section applies only to those vehicles equipped with theoptional security system (TSSM).
NOTE
Disarming function may require practice. The key fob buttonmust be pressed twice within 1.5 seconds to send the disarmcommand. The action is very similar to double-clicking a com-puter mouse. Light quick taps work best; very hard or very slowtaps are less likely to work.
The key fob sends a RF signal to activate all remote TSSMfunctions. The left front turn signal switch wire serves as thevehicle's antenna. If the TSSM does not respond (no confirm-ation at arming/disarming system) or responds weakly (limitedrange, won't consistently arm/disarm or synchronize), followthe flow chart.
Job/Time Code ValuesDealership technicians filing warranty claims should use thejob/time code values printed in bold text underneath theappropriate repair.

DIAGNOSTICS
Diagnostic Tips• Verify key fob battery voltage is at least 2.9 volts. See
E.22 TSSM MAINTENANCE.
• Interference from physical surroundings may affect RFtransmission. Place fob next to left handgrip and disarmwith two clicks or move motorcycle to a new location andretest.
• Check for damage to antenna wire. Does left turn signalwork?
NOTE
See E.7 ARMING/DISARMING: TSSM. Use only the properkey fob for your market and TSSM package.
Diagnostic NotesEach reference number below correlates to a circled numberon the flow chart(s).
After a battery disconnect, the TSSM will not enter the config-uration mode on the first attempt. All attempts to assign a fobor enter the configuration mode will require at least twoattempts.

Diagnostic Tips: All• Diagnostic Trouble Codes (DTCs) B1121 and B1122 will
illuminate the security lamp.
• DTC B1141 will not illuminate the security lamp.
• When the TSM/TSSM is in 4-way flasher mode, a fault oneither the left or right turn lamp output will not cause eitherDTC B1121 and DTC B1122 to be set. If fault occurs on
both left and right outputs, then both DTC B1121 and DTCB1122 will be set.
• When the TSM/TSSM detects an over-current or short toground condition, it will turn off the turn lamp outputs.Theoutputs will be automatically reactivated once the fault isremoved.
Diagnostic Notes: All Turn Signal FlowChartsEach reference number below correlates to a circled numberon the flow chart(s).
1. Gain access to vehicle's TSM/TSSM. Perform the followingprocedure:
a. See Figure E-18. Position TSM/TSSM in the sameorientation it is mounted on vehicle. Turn on ignitionswitch. Turn on 4-way flashers by depressing bothleft and right turn signal switches simultaneously.Turnignition off; 4-way flashers should continue to flash.
b. Tilt module greater than 45 degrees to the left.
c. Repeat step a.
d. Tilt module greater than 45 degrees to the right.
2. To enable diagnostic mode, see E.8 DIAGNOSTICTROUBLE CODES (DTC).

GENERAL
Battery Voltage HighThe TSM/TSSM continually checks the battery voltage duringIGN/OFF and IGN/RUN power modes. If the voltage exceeds16.0 volts for more than 5.0 ± 0.5 seconds, the TSM/TSSMsets diagnostic trouble code (DTC) B0563.
DIAGNOSTICS
Diagnostic Tips• This DTC may set when the vehicle is placed on a battery
charger, on fast charge, for a long period of time.
• The TSSM does not illuminate the security lamp when thisDTC is set.
Diagnostic NotesSee 1.7 CHARGING SYSTEM tests to correct. Problem maybe faulty voltage regulator.

Alarm Output Low (DTC B1131) or AlarmOutput High (DTC B1132)See Figure E-20. An alarm cycle is activated when the TSSMis connected, the siren has been armed by the TSSM and asecurity event occurs. See E.6 SECURITY SYSTEM FUNC-TIONS: TSSM. Under normal armed operation, the siren input(terminal "2") is driven low by the TSSM to trigger the audiblealarm. When the siren input is driven high by the TSSM theaudible alarm stops.

Diagnostic Tips• If the siren is armed and the internal siren battery is dead,
shorted, disconnected, or has been charging for a period
longer than 24 hours, the siren will respond with threechirps on arming instead of two.
• The internal siren battery may not charge if the vehicle'sbattery is less than 12.5 volts.
• If the siren does not chirp two or three times on a validarming command from the TSSM, the siren is either notconnected, not working, or the siren wiring was openedor shorted while the siren was disarmed.
• If the siren enters the self-driven mode where it is poweredfrom the siren internal nine-volt battery, the turn-signallamps will not alternately flash. If the TSSM activates thesiren, the turn-signal lamps will flash. If the siren has beenarmed and a security event occurs, and the siren is in self-driven mode, the siren will alarm for 20 to 30 seconds andthen turn off for 5 to 10 seconds. This alarm cycle will berepeated ten times if the siren is in the self-driven mode.
• If the siren does not stop alarming after it has been armed,then either the TSSM output or siren input may be shortedto ground, or the siren vehicle battery connection is openor shorted to ground, or the siren vehicle ground connec-tion is open, or a security event has occurred. SeeE.6 SECURITY SYSTEM FUNCTIONS: TSSM for adescription of alarm functions.
Diagnostic NotesEach reference number below correlates to a circled numberon the flow chart(s).
1. Use BREAKOUT BOX (Part No. HD-42682) and HAR-NESS CONNECTOR TEST KIT (Part No. HD-41404-B),gray pin probe and patch cord. See E.11 BREAKOUTBOX: TSM/TSSM.
2. Use HARNESS CONNECTOR TEST KIT (Part No. HD-41404-B), gray socket probe and patch cord.
3. Having the correct multimeter ohm scale is important forthis test. Some meters may read infinity for high ohmvalues. If this is the case, check your ohm scale and retest.

Loss of ECM Serial DataThe serial data connector provides a means for the ElectronicControl Module (ECM), TSM/TSSM, and speedometer tocommunicate their current status. When all operating para-meters on the serial data bus are within specifications, a stateof health message is sent between the components. A dia-gnostic trouble code DTC U1016 indicates that the ECM is notcapable of sending this state of health message. A DTC U1016indicates there was communication on the data bus since powerup, but was lost or interrupted during that key cycle.
