HOW TO USE THIS MANUAL B
This manual provides information on the electrical circuits installed on vehicles bydividing them into a circuit for each system.
The actual wiring of each system circuit is shown from the point where the powersource is received from the battery as far as each ground point. (All circuitdiagrams are shown with the switches in the OFF position.)
When troubleshooting any problem, first understand the operation of the circuitwhere the problem was detected (see System Circuit section), the power sourcesupplying power to that circuit (see Power Source section), and the ground points(see Ground Point section). See the System Outline to understand the circuitoperation.
When the circuit operation is understood, begin troubleshooting of the problemcircuit to isolate the cause. Use Relay Location and Electrical Wiring Routingsections to find each part, junction block and wiring harness connectors, wiringharness and wiring harness connectors, splice points, and ground points of eachsystem circuit. Internal wiring for each junction block is also provided for betterunderstanding of connection within a junction block.Wiring related to each system is indicated in each system circuit by arrows(from__, to__). When overall connections are required, see the Overall ElectricalWiring Diagram at the end of this manual.

B HOW TO USE THIS MANUAL
Current is applied at all times through the STOP fuse to TERMINAL 2 of the stop light SW.When the ignition SW is turned on, current flows from the GAUGE fuse to TERMINAL 8 of the light failure sensor, and also flowsthrough the rear lights warning light to TERMINAL 4 of the light failure sensor.
Stop Light Disconnection WarningWhen the ignition SW is turned on and the brake pedal is pressed (Stop light SW on), if the stop light circuit is open, the currentflowing from TERMINAL 7 of the light failure sensor to TERMINALS 1, 2 changes, so the light failure sensor detects thedisconnection and the warning circuit of the light failure sensor is activated.As a result, the current flows from TERMINAL 4 of the light failure sensor to TERMINAL 11 to GROUND and turns the rear lightswarning light on. By pressing the brake pedal, the current flowing to TERMINAL 8 of the light failure sensor keeps the warningcircuit on and holds the warning light on until the ignition SW is turned off.

(a) Establish conditions in which voltage is present at the checkpoint.
Example:[A] – Ignition SW on[B] – Ignition SW and SW 1 on[C] – Ignition SW, SW 1 and Relay on (SW 2 off)
(b) Using a voltmeter, connect the negative lead to a good groundpoint or negative battery terminal, and the positive lead to theconnector or component terminal.This check can be done with a test light instead of a voltmeter.
CONTINUITY AND RESISTANCE CHECK
(a) Disconnect the battery terminal or wire so there is no voltagebetween the check points.
(b) Contact the two leads of an ohmmeter to each of the checkpoints.
If the circuit has diodes, reverse the two leads and checkagain.When contacting the negative lead to the diode positive sideand the positive lead to the negative side, there should becontinuity.When contacting the two leads in reverse, there should be nocontinuity.
(c) Use a volt/ohmmeter with high impedance (10 kΩ/Vminimum) for troubleshooting of the electrical circuit.

E GLOSSARY OF TERMS AND SYMBOLS
BATTERYStores chemical energy andconverts it into electrical energy.Provides DC current for the auto’svarious electrical circuits.
GROUNDThe point at which wiring attaches tothe Body, thereby providing a returnpath for an electrical circuit; without aground, current cannot flow.
CAPACITOR (Condenser)A small holding unit for temporarystorage of electrical voltage.
HEADLIGHTSCurrent flow causes a headlightfilament to heat up and emit light. Aheadlight may have either a single(1) filament or a double (2) filament
1. SINGLE FILAMENT
CIGARETTE LIGHTERAn electric resistance heatingelement.
2. DOUBLE FILAMENT
CIRCUIT BREAKERBasically a reusable fuse, a circuitbreaker will heat and open if toomuch current flows through it.Some units automatically reset whencool, others must be manually reset.
HORNAn electric device which sounds aloud audible signal.
DIODEA semiconductor which allowscurrent flow in only one direction.
IGNITION COILConverts low–voltage DC currentinto high–voltage ignition current forfiring the spark plugs.
DIODE, ZENERA diode which allows current flow in onedirection but blocks reverse flow only upto a specific voltage. Above that potential,it passes the excess voltage. This acts asa simple voltage regulator.
LIGHTCurrent flow through a filamentcauses the filament to heat up andemit light.
PHOTODIODEThe photodiode is a semiconductorwhich controls the current flowaccording to the amount of light.
LED (LIGHT EMITTING DIODE)Upon current flow, these diodes emitlight without producing the heat of acomparable light.
DISTRIBUTOR, IIAChannels high–voltage current fromthe ignition coil to the individualspark plugs.
METER, ANALOGCurrent flow activates a magneticcoil which causes a needle to move,thereby providing a relative displayagainst a background calibration.
FUSEA thin metal strip which burns throughwhen too much current flows through it,thereby stopping current flow andprotecting a circuit from damage.
FUSIBLE LINK
METER, DIGITALCurrent flow activates one or manyLED’s, LCD’s, or fluorescentdisplays, which provide a relative ordigital display.
FUEL
FUSIBLE LINKA heavy–gauge wire placed in highamperage circuits which burns through onoverloads, thereby protecting the circuit.The numbers indicate the crosssectionsurface area of the wires.
(for Medium Current Fuse)
(for High Current Fuse or Fusible Link)
MOTORA power unit which convertselectrical energy into mechanicalenergy, especially rotary motion.

operational.
SENSOR (Thermistor)A resistor which varies its resistancewith temperature.
SWITCH, WIPER PARKAutomatically returns wipers to thestop position when the wiper switchis turned off.
(Reed Switch Type)
SENSOR, SPEEDUses magnetic impulses to openand close a switch to create a signalfor activation of other components.
TRANSISTORA solidstate device typically used asan electronic relay; stops or passescurrent depending on the voltageapplied at ”base”.
SHORT PINUsed to provide an unbrokenconnection within a junction block.
WIRESWires are always drawn asstraight lines on wiringdiagrams.Crossed wires (1) without ablack dot at the junction are
(1) NOT CONNECTED
SOLENOIDAn electromagnetic coil which formsa magnetic field when current flows,to move a plunger, etc.

This system utilizes an engine ECU and maintains overall control of the engine, transmission and so on. An outline of theengine control is explained here.
1. Input Signals(1) Water temp. signal circuit
The water temp. sensor detects the engine coolant temp. and has a built–in thermistor with a resistance variesaccording to the engine coolant temp. Thus the engine coolant temp. is input in the form of a control signal toTERMINAL THW of the engine ECU.
(2) Intake air temp. signal circuitThe intake air temp. sensor is detects the intake air temp. of air cleaner, which is input as a control signal to TERMINALTHA of the engine ECU.The intake air temp. sensor is detects the intake air temp. of inter cooler, which is input as a control signal to TERMINALTHIA of the engine ECU.
(3) RPM signal circuitCamshaft position and crankshaft position are detected by the camshaft position sensor and crankshaft position sensor.Camshaft position is input as a control signal to TERMINAL G+ of the engine ECU, and engine RPM is input intoTERMINAL NE+.
(4) Throttle signal circuitThe accelerator position sensor detects the accelerator pedal opening angle, which is input as a control signal toTERMINALS VPA and VPA2 of the engine ECU.
(5) Vehicle speed signal circuitThe speed sensor detects the vehicle speed and inputs a control signal to TERMINAL SPD of the engine ECU via thecombination meter.
(6) Battery signal circuitVoltage is constantly applied to TERMINAL BATT of the engine ECU. When the ignition SW is turned to on, voltage forengine ECU operation is applied via the MAIN relay to TERMINAL +B of the engine ECU.
(7) Started signal circuitTo confirm that the engine is cranking, the voltage applied to the starter motor during cranking is detected and is input asa control signal to TERMINAL STA of the engine ECU.
(8) Fuel temp. signal circuitThe fuel temp. sensor is detects the fuel temp., which is input as a control signal to TERMINAL THF of the engine ECU.
(9) Intake air vacuum pressure signal systemIntake air vacuum pressure is detected by the turbo pressure sensor and is input as a control signal to TERMINAL PIMof the engine ECU.

Engine Control
2. Control System∗ EGR control
The EGR control system detects the signals from each sensor, then the current is output to the TERMINAL EGR to controlthe VRV (EGR).
∗ Common rail pressure controlThe target rail pressure is calculated according to the engine status (Accelerator opening, engine speed) andenvironmental change detected by sensors. The fuel amount to be pressure–fed from the supply pump is calculated so asto match the indicated value of rail pressure sensor with the target value and the signal is sent to the intake amountadjusting valve of the supply pump in order to control the rail pressure.
∗ Fuel injection timing controlThe fuel injection timing is controlled by calculating the basic fuel injection timing based on the engine status (Acceleratoropening, engine speed), making corrections according to environmental change detected by sensors, then sending asignal to the solenoid control valve of the injector via the injector driver (EDU).
∗ Fuel injection volume controlThe fuel injection volume is controlled by calculating the basic fuel injection volume based on the engine status(Accelerator opening, engine speed), making corrections according to environmental change detected by sensors and theinside pressure conditions in the rail, then sending a signal to the solenoid control valve of the injector via the injectordriver (EDU).
∗ Pilot injection controlThe fuel injection volume and timing are controlled by calculating the pilot injection volume/timing based on the enginestatus (Accelerator opening, engine speed), making corrections according to environmental change detected by sensors,then sending a signal to the solenoid control valve of the injector via the injector driver (EDU).
3. Diagnosis SystemWith the diagnosis system, when there is a malfunctioning in the engine ECU signal system, the malfunction system isrecorded in the memory. The malfunctioning system can be found by reading the display (Code) of the check engine warninglight.
4. Fail–Safe SystemWhen a malfunction occurs in any system, if there is a possibility of engine trouble being caused by continued control basedon the signals from that system, the fail–safe system either controls the system by using data (Standard values) recorded inthe engine ECU memory or else stops the engine.

The current is applied at all times to TERMINAL 1 of the combination meter through the DOME fuse.When the ignition SW is turned to ON position, the current flows to TERMINAL 21 of the combination meter through the METfuse. When the light control SW is turned to TAIL or HEAD position, current is applied to TERMINAL 8 of the combinationmeter through the TAIL fuse.
1. Key Reminder SystemWhen the driver door is opened with the ignition SW off and ignition key remaining in the key cylinder (Unlock warning SWon), a signal is input from the unlock warning SW to TERMINAL 10 of the combination meter, and from the door courtesy SW(Driver’s side) to TERMINAL 16 of the combination meter. As a result, the buzzer in the combination meter goes on andwarns the driver that the key is remaining in the key cylinder.
2. Light Reminder SystemWhen the light control SW is in TAIL or HEAD position, the ignition SW turned to OFF from ON position, ignition key is not inthe key cylinder and the driver’s door opened (Door courtesy SW on), the current flows to TERMINAL 21 of the combinationmeter stops. As a result, the combination meter is activated and current flows from TERMINAL 1 of the combination meter,the buzzer in the combination meter goes on to remind the light is lighting up.

Previous automatic transmissions have selected each gear shift using mechanically controlled throttle hydraulic pressure,governor hydraulic pressure and lock–up hydraulic pressure. The electronically controlled transmission, however, electricallycontrols the line pressure, throttle pressure, lock–up pressure and accumulator pressure etc. through the solenoid valve. Theelectronically controlled transmission is a system which precisely controls gear shift timing and lock–up timing in response tothe vehicle’s driving conditions and the engine condition detected by various sensors. It makes smooth driving possible byshift selection for each gear which is the most appropriate to the driving conditions at that time, and by preventing downing,squat and gear shift shock when starting off.
1. Lock–Up OperationWhen the transmission control ECU decides based on each signal that the lock–up condition has been met, the currentflows through TERMINAL SL of the transmission control ECU to TERMINAL 7 of the ECT solenoid to GROUND, causinglock–up operation.
2. Stop Lamp SW CircuitIf the brake pedal is depressed (Stop lamp SW on) when driving in lock–up condition, a signal is input to TERMINAL STP ofthe transmission control ECU. The transmission control ECU operates and cuts the current to the solenoid to releaselock–up.

This system controls the respective brake fluid pressures acting on the brake cylinders of the right front wheel, left frontwheel, and rear wheels when the brakes are applied in a panic stop so that the wheels do not lock.This results in improved directional stability and steerability during panic braking.
1. Input Signal(1) Speed sensor signal
The speed of the wheels is detected and input to TERMINALS FL+, FR+, RL+ and RR+ of the skid control ECU withactuator.
(2) Stop lamp SW signalA signal is input to TERMINAL STP of the skid control ECU with actuator when the brake pedal is depressed.
2. System OperationDuring sudden braking, the skid control ECU with actuator which has signals input from each sensor lets the hydraulicpressure acting on each wheel cylinder escape to the reservoir.The pump inside the skid control ECU with actuator is also operating at this time and it returns the brake fluid from thereservoir to the master cylinder, thus preventing locking of vehicle wheels.If the skid control ECU with actuator judges that the hydraulic pressure acting on the wheel cylinder is insufficient, the currentacting on the solenoid is controlled and the hydraulic pressure is increased.Holding of the hydraulic pressure is also controlled by the ECU, by the same method as above, by repeated pressurereduction. Holding and increase are repeated to maintain vehicle stability and to improve steerability during sudden braking.

SRS
NOTICE: When inspecting or repairing the SRS, perform service in accordance with the following precautionary instructionsand the procedure, and precautions in the Repair Manual applicable for the model year.
Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most important source of informationwhen troubleshooting. When troubleshooting the SRS, always inspect the DTCs before disconnecting the battery.
Work must be started more than 90 seconds after the ignition SW is turned to the ”LOCK” position and thenegative (–) terminal cable is disconnected from the battery.(The SRS is equipped with a back–up power source so that if work is started within 90 seconds fromdisconnecting the negative (–) terminal cable of the battery, the SRS may deploy.)
When the negative (–) terminal cable is disconnected from the battery, the memory of the clock and audio system will becleared. So before starting work, make a record of the contents in the audio memory system. When work is finished,reset the audio systems as they were before and adjust the clock. Some vehicles have power tilt steering, powertelescopic steering, power seat and power outside rear view mirror which are all equipped with memory function.However, it is not possible to make a record of these memory contents. So when the work is finished, it will benecessary to explain it to your customer, and ask the customer to adjust the features and reset the memory. To avoiderasing the memory in each system, never use a back–up power supply from outside the vehicle.
Before repair, remove the airbag sensor if shocks are likely to be applied to the sensor during repair.
Do not expose the following parts directly to hot air or flame;
Even in cases of a minor collision where the SRS does not deploy, the following parts should be inspected;
Never use SRS parts from another vehicle. When replacing parts, replace with new parts.
For the purpose of reuse, never disassemble and repair the following parts.
If the following parts have been dropped, or have cracks, dents and other defects in their case, bracket, and connector,replace with new one.

The SRS is a driver protection device which has a supplemental role to the seat belts.When the ignition SW is turned to ON, the current from the ignition SW flows to TERMINAL 21 of the airbag sensor assemblycenter.If an accident occurs while driving, when the frontal impact exceeds a set level, the current from the ignition SW flows toTERMINAL 5 of the airbag sensor assembly center to the airbag squibs TERMINAL 6 of the airbag sensor assembly centerto TERMINAL 25, 26 or BODY GROUND to GROUND, so that current flows to the airbag squibs and causes them tooperate.The airbag stored inside the steering wheel pad is instantaneously expanded to soften the shock to the driver.

Driving mode is switched to H2 or H4 or L4 when the driver operates the transfer shift lever. Transfer indicator SW (4WDposition) is turned on when the transfer shift lever is shifted in 4WD (H4 or L4).
1. 2-4 Select System(1) Shifting from H4 to H2
When the transfer shift lever is changed from H4 to H2 position, transfer indicator SW (4WD position) detects OFF signalto activate the ADD motor, which results in changing the transfer to 2WD (H2 position).At this time, the transfer indicator SW (4WD position) are off.
(2) Shifting from H2 to H4When the transfer shift lever is changed from H2 to H4 position, transfer indicator SW (4WD position) detects ON signalto activate the ADD motor, which results in changing the transfer to 4WD (H4 position) to light up 4WD indicator.
(3) Shifting from H4 to L4When the transfer shift lever is changed from H4 to L4 position, the shift fork shaft moves to change the transfer to 4WD(L4 position), which results in turning ON transfer indicator SW (L4 position). ADD motor does not operate since it is onlythe lever operation.
(4) Shifting from L4 to H4When the transfer shift lever is changed from L4 to H4 position, the shift fork shaft moves. When transfer indicator SW(L4 position) is turned OFF, the transfer changes to 4WD (H4 position). ADD motor does not operate since it is only thelever operation.
2. Other ControlWhen abnormality is found in the 4WD system, the driver is warned by 4WD indicator light’s flashing.

When the ignition SW is turned to ACC position the current from the ACC fuse flows to TERMINAL 6 of the shift lock controlECU. When the ignition SW is turned to ON position, the current from the ECU–IG&GAUGE fuse flows to TERMINAL 1 ofthe shift lock control ECU.
1. Shift Lock MechanismIf the brake pedal is depressed with the ignition SW set at ON (The stop lamp SW is on), the shift lock control ECU isactivated, allowing the driver to change the shift lever to a position other than the P position.
2. Key Interlock MechanismWith the ignition SW at ON or ACC position, when the shift lever is put in P position, the current flowing from TERMINAL 12of the shift lock control ECU to key interlock solenoid is cut off. This causes the key interlock solenoid to turn off (Lock leverdisengages from LOCK position) and the ignition key can be turned from ACC to LOCK position.

Door lock control (Lock and unlock) and panic control (Theft alarm and flash) is performed by remote control, without theignition key inserted in the door key cylinder, using low–power electrical waves emitted by a transmitter.
1. Normal Operation∗ Lock operation
When the lock button on the transmitter is pressed, all the doors are locked.∗ Unlock operation
When the unlock button on the transmitter is pressed, all the doors are locked.
2. Visual Confirmation of Lock or UnlockIf all doors indicate that they are locked after the lock command, security horn sound and hazard lights will sound and flashonce. If any door indicates that it is open after the unlock command, theft deterrent horn sound and hazard lights will soundand flash twice.
3. Automatic Lock OperationAll the doors are automatically relocked unless any door is opened within 15 seconds after pushing the button (Transmitter)to unlock all the doors under conditions that the ignition key is not inserted into the ignition key cylinder (Unlock warning SWoff), ignition SW is at OFF and all the doors are completely closed.
4. Illuminated Entry FunctionWhen pushing the unlock button (Transmitter), it turns on the lights, such as the ignition key cylinder lamp for approx. 30seconds. If the doors are locked with lock button (Transmitter) during this operation and ignition key is in the ignition keycylinder (Unlock warning SW ON) to turn ON the ignition SW, lighting is cancelled and the lights immediately fade out.
5. Panic Alarm OperationWhen the panic button on the transmitter is pushed, alarm sound and flash starts. The panic alarm operation is canceledwhen one of the lock button, unlock button and panic alarm button is pressed.
6. Door Ajar Warning (By Pushing Wireless Lock Button)Half–shut door is warned with security horn sound (For 1 second) by pushing the lock button (Transmitter) when one of thedoors is not completely shut.

Power Window
1. Manual Down or Up OperationWhen the power window master SW is pushed one step, the motor rotates to open the window.When the power window master SW is pulled up one step, the motor rotates in the opposite direction, to close the window.All the other windows can be opened/closed as well, by the operation of the power window master SW or respective powerwindow SW.When the window lock SW is pushed to the lock side, the ground circuit to the passenger’s window becomes open. As aresult, even if Open/Close operation of the passenger’s window is attempted, the current from TERMINAL E of the powerwindow master SW is not grounded and the motor does not rotate, so the passenger’s window can not be operated andwindow lock occurs.
2. Auto Down Operation (Driver’s Window)When the power window master SW is pushed two steps, the motor rotates to open the window automatically.
3. Stopping of Auto Down Operation (Driver’s Window)Auto operation can be stopped in mid–course with switching power window master SW one step upward during the downoperation.

With the ignition SW turned on, the current flows to TERMINAL (B) 3 of the front wiper and washer SW, TERMINAL 1 of thewindshield washer motor and TERMINAL 2 of the windshield wiper motor through the WIP fuse.
1. Low Speed PositionWith the front wiper SW turned to LO position, the current flows from TERMINAL (B) 3 of the front wiper and washer SW toTERMINAL (B) 2 to TERMINAL 5 of the windshield wiper motor to TERMINAL 4 to GROUND and causes the windshieldwiper motor to run at low speed.
2. High Speed PositionWith the front wiper SW turned to HI position, the current flows from TERMINAL (B) 3 of the front wiper and washer SW toTERMINAL (B) 1 to TERMINAL 3 of the windshield wiper motor to TERMINAL 4 to GROUND and causes the windshieldwiper motor to run at high speed.
3. INT PositionWith the front wiper SW turned to INT position, the wiper relay operates and current flows from TERMINAL (B) 3 of the frontwiper and washer SW to TERMINAL (A) 2 to GROUND. This activates the intermittent circuit and the current flows fromTERMINAL (B) 3 of the front wiper and washer SW to TERMINAL (B) 2 to TERMINAL 5 of the windshield wiper motor toTERMINAL 4 to GROUND and the wiper operates.The intermittent operation is controlled by the charge/discharge function of the condenser installed in the relay, and theintermittent time is controlled by a time control SW to change the charging time of the condenser (w/ INT time SW).Intermittent operation is controlled by a condenser charge and discharge function in the relay (w/o INT time SW).
4. Mist PositionWith the front wiper SW turned to MIST position, the current flows from TERMINAL (B) 3 of the front wiper and washer SW toTERMINAL (B) 2 to TERMINAL 5 of the windshield wiper motor to TERMINAL 4 to GROUND and causes the windshieldwiper motor to run at low speed.
5. Washer Interlocking OperationWith the washer SW pulled to ON position, the current flows from the WIP fuse to TERMINAL 1 of the windshield washermotor to TERMINAL 2 to TERMINAL (A) 1 of the front wiper and washer SW to TERMINAL (A) 2 to GROUND and causesthe windshield washer motor to run and the window washer to spray. Simultaneously, current flows from the WIP fuse toTERMINAL (B) 3 of the front wiper and washer SW to TERMINAL (B) 2 to TERMINAL 5 of the windshield wiper motor toTERMINAL 4 to GROUND, causing the wiper to function.

Current is applied at all times through the FR HTR fuse to TERMINAL 5 of the HTR relay.When the ignition SW is turned on, the current flows through the ECU–IG&GAUGE fuse to TERMINAL 1 of the HTR relay toTERMINAL 2 to TERMINAL 6 of the blower SW.
Blower Motor Operation∗ Low speed operation
When the blower SW is moved to LO position, the current flows to TERMINAL 6 of the blower SW to TERMINAL 5 toGROUND, causing the HTR relay to turn on. This causes the current flows from the FR HTR fuse to TERMINAL 5 of theHTR relay to TERMINAL 3 to TERMINAL 2 of the blower motor to TERMINAL 1 to TERMINAL 4 of the blower resistor toTERMINAL 1 to GROUND, rotating the blower motor at low speed.
∗ Medium speed operation (Operation at M1, M2)When the blower SW is moved to M1 position, the current flows to TERMINAL 6 of the blower SW to TERMINAL 5 toGROUND, causing the HTR relay to turn on. This causes the current flows from the FR HTR fuse to TERMINAL 5 of theHTR relay to TERMINAL 3 to TERMINAL 2 of the blower motor to TERMINAL 1 to TERMINAL 4 of the blower resistor toTERMINAL 3 to TERMINAL 2 of the blower SW to TERMINAL 5 to GROUND. At this time, the blower resistance of theblower resistor is smaller than at low speed, so the blower motor rotates at medium low speed.When the blower SW is moved to M2 position, the current flows through the HTR relay to TERMINAL 2 of the blowermotor to TERMINAL 1 to TERMINAL 4 of the blower resistor to TERMINAL 2 to TERMINAL 1 of the blower SW toTERMINAL 5 to GROUND. At this time, resistance of the blower resistor is smaller than at M1 position, so the blowermotor rotates at medium high speed.
∗ High speed operationWhen the blower SW is moved to HI position, the current flows to TERMINAL 6 of the blower SW to TERMINAL 5 toGROUND, causing the HTR relay to turn on.This causes the current flows from the FR HTR fuse to TERMINAL 5 of the HTR relay to TERMINAL 3 to TERMINAL 2of the blower motor to TERMINAL 1 to TERMINAL 4 of the blower SW to TERMINAL 5 to GROUND, rotating the blowermotor at high speed.
