Wheels and Tires - Tire Pressure Monitoring System (TPMS) Diagnosis and Testing

Principles of Operation

For a detailed description of the Tire Pressure Monitoring System, refer to the relevant Description and Operation section inthe workshop manual.REFER to: (204-04 Wheels and Tires, Description and Operation).Wheels and Tires

Inspection and Verification

CAUTION: Diagnosis by substitution from a donor vehicle is acceptable. Substitution of control modules does not NOTguarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.

NOTES:

If a control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty Policy and Procedures manual, or determine if any prior approval programme is in operation, prior to the installationof a new module/component.

When performing voltage or resistance tests, always use a digital multimeter accurate to three decimal places, and with an up-to-date calibration certificate. When testing resistance always take the resistance of the digital multimeter leads intoaccount.

Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.

NOTE: Tire pressure adjustments are part of routine owner maintenance. Tire pressure adjustments that are required due to a lack of owner maintenance are not to be claimed under vehicle warranty.

The tire pressures should be checked using a calibrated tire pressure gauge and when the tires are cold (vehicle parked in theambient temperature for at least one hour, not in a garage with an artificial ambient temperature).

If the tire pressure warning indicator/message does not clear within two minutes of adjusting the tire pressures, it is likelythat the gauge is not correctly calibrated or the tires are warm. Perform the following steps until the warning has cleared:

Rotate the wheels by 180°

Increase the tire pressures by 3psi

Wait a further two minutes

Reset the tire pressures to the correct pressure

Wheels and Tires - Wheels and Tires Description and Operation

TIRES

NOTE: The TPMS valve should be serviced using the suitable service kit, each time the tyre is dismounted, to ensure an air tight seal. Attention should be made to the detail of fitting this kit.

Care must be taken when removing and refitting tires to ensure that the tire pressure sensor is not damaged.

Item Description

Tire valve and pressure sensor

Tire fitting/removal tool initial start position

High tire and bead tension area

Low tire and bead tension area

When removing the tire, the bead breaker must not be used within 90 degrees of the tire valve in each direction.

When using the tire removal machine, the fitting arm start position must be positioned as shown in the tire changingillustration. The wheel can then be rotated through 180 degrees in a counterclockwise direction. This will relieve the hightension from the tire bead allowing the remaining 180 degrees of the tire to be manually pulled from the rim.

When refitting the tire, position the fitting arm as shown. Rotate the tire and take care that the bead on the low tension sideof the tire does not damage the sensor.

Tread Act - NAS Only

Vehicles supplied to the North American markets must comply with the legislation of the Transport Recall Enhancement,Accountability and Documentation (TREAD) act. Part of the requirement of the TREAD act is for the vehicle to display a label,positioned on the driver's side B-pillar, which defines the recommended tire inflation pressure, load limits and maximum loadof passengers and luggage weight the vehicle can safely carry. This label will be specific to each individual vehicle and will beinstalled on the production line.

This label must not be removed from the vehicle. The label information will only define the specification of the vehicle as itcame off the production line. It will not include dealer or owner fitted accessory wheels and tires of differing size from theoriginal fitment.

NOTE: If tires and wheels of a non-standard size are fitted to the vehicle, the car configuration file must be updated using a Land Rover approved diagnostic system.

If the label is damaged or removed for body repair, it must be replaced with a new label specific to that vehicle. A new label isrequested from Land Rover parts and will be printed specifically for the supplied VIN of the vehicle.

The purpose of the Tire Pressure Monitoring System (TPMS) is to assist the driver in maintaining the vehicle’s tire pressures atthe optimum level in order to:

improve fuel consumptionmaintain ride and handling characteristicsreduce the risk of rapid tire deflation – which may be caused by under inflated tires

comply with legislation in relevant markets.

The TPMS measures the pressure in each of the tires on the vehicle (including the spare, if required) and issues warnings tothe driver if any of the pressures deviate from defined tolerances.

NOTES:

During a ‘blow out’ a very rapid reduction in pressure is experienced. The system is not intended to warn the driver of a ‘blow out’, since it is not possible to give the driver sufficient warning that such an event is occurring, due to its shortduration. The design of the TPMS is to assist the driver in keeping the tires at the correct pressure, which will tend to reducethe likelihood of a tire ‘blow out’ occurring.

TPMS is inhibited when the vehicle is in Delivery mode. For more details on Delivery mode refer to the PDI manual.

A single TPMS hardware configuration is used. TPMS status information is relayed to the driver with a message displayed inthe instrument cluster message center and a amber warning indicator.

Tire Location

Because of the requirement for different pressure targets and thresholds for the front and rear tires, the CJB (central junction can identify the location of the tires on the vehicle, and assign a received tire pressure sensor identification to a specificbox)

position on the vehicle (i.e. FL (front left), FR (front right), RL (rear left) or RR (rear right)).

Tire location is performed automatically by the using an auto-location function. This function requires no manualCJBintervention by the driver. The can automatically learn the position of tires on the vehicle if the tire pressure sensors orCJBtheir positions are changed on the vehicle.

The tire learn and location process is ready to commence when the vehicle has been stationary or is traveling at less than12.5 mph (20 km/h) for 15 minutes. This is known as 'parking mode'. The learn/locate process requires the vehicle to bedriven at speeds of more than 12 mph (20 km/h) for 15 minutes. If the vehicle speed reduces to below 12 mph (20 km/h),the learn process timer is suspended until the vehicle speed increases to more than 12 mph (20 km/h), after which time thetimer is resumed. If the vehicle speed remains below 12.5 mph (20 km/h) for more than 15 minutes, the timer is set to zeroand process starts again.

The can automatically detect, under all operating conditions, the following:CJB

one or more tire pressure sensors have been replacedone or more tire pressure sensor identifications are missingone or more ‘alien’ identifications are being received, i.e. the can reject identifications from tire pressure sensorsCJBthat do not belong to the vehiclethe spare tire and one of the tires in use on the vehicle have exchanged position on the vehicle.

If the tire pressure sensors fitted to the running wheels (not the spare) are changed, the can learn the new sensorCJBidentifications automatically. The learn function requires no manual intervention by the driver.

If a new sensor is fitted to the spare tire it must have its identification code programmed into the using a Land RoverCJBapproved diagnostic system, or used on the vehicle as a 'running' wheel and the vehicle driven for 15 minutes at more than12.5 mph (20 km/h).

Spare Tire Identification

Depending on the vehicle specification, the spare tire may or may not be fitted with a tire pressure sensor.

NOTE: Tire pressure sensors cannot be fitted to steel space saver spare wheels.

If the spare tire is fitted with a tire pressure sensor, the can detect it, determine that it is the spare tire and monitor itsCJBpressure and issue warnings to the driver accordingly. If the expects the spare tire to be fitted with a tire pressure sensorCJBand it does not, the will not show a fault to the driver, however a fault code will be stored in the .CJB CJB

If the spare tire is being monitored and the driver replaces a flat ‘running’ tire with the spare tire, the will not continuallyCJBwarn the driver that the original flat tire (now in the spare position) is flat. This prevents distraction of the driver by constantpressure warnings being issued. The driver is reminded by a message displayed for 20 seconds at each ignition on cycle thatthe spare tire is flat.

System Operation

Each time the vehicle is driven, the transmits a Low Frequency (LF) (125 KHz) signal to each initiator in turn. This isCJBreceived by the tire pressure sensor which transmits a Radio Frequency (RF) (315 or 433 MHz depending on market) signal tothe RF receiver. This signal contains coded data which corresponds to sensor identification, air pressure, air temperature andacceleration data. This signal is communicated to the via a K-bus line.CJB

The system enters 'parking mode' after the vehicle speed has been less than 12.5 mph (20 km/h) for 12 minutes. In parkingmode the tire pressure sensors transmit a coded signal to the once every 13 hours. If the tire pressure decreases byCJBmore than 1 lbf/in (0.6 bar) the sensor will transmit more often if pressure is being lost.2

The spare tire sensor transmits a signal every 13 hours in the same manner as the road wheels when in parking mode. If thetire pressure decreases by more than 1 lbf/in (0.6 bar) the sensor will transmit more often if pressure is being lost.2

As each wheel responds to the LF signal from the , it is assigned a position on the vehicle and is monitored for theCJBremainder of that drive cycle in that position.

When the vehicle has been parked for more than 15 minutes and then driven at a speed of more than 12.5 mph (20 km/h),the initiators fire in turn for 18 seconds in the following order:

Front left6 second pause (for the to detect a response from the tire pressure sensor)Front right6 second pauseRear right6 second pauseRear left6 second pause.

Each tire pressure sensor responds in turn so the can establish the sensor positions at the start of the drive cycle. ThisCJBprocess is repeated up to three times but less if the sensor positions are already known in the . The process is known asCJB'Auto Location' and takes 7 to 8 minutes to complete. During this period the tire sensors transmit at regular intervals, onceevery 15 seconds. For the remainder of the drive cycle the tire sensors transmit once every 60 seconds or if a change in tirepressure is sensed until the vehicle stops and the system returns to parking mode.

Once the wheel position is established, the initiators stop firing a signal and do not fire again until the vehicle has been parkedfor more than 15 minutes. The signal transmissions from each wheel sensor continue at 1 minute intervals whilst the vehicleis being driven. This transmission is to monitor the tire pressure.

At 25% deflation the amber warning indicator in the instrument cluster is illuminated and an appropriate message displayed inthe message center.

RF Receiver

The RF receiver is mounted behind the overhead console and connects to the vehicle harness via a fly lead.

The RF receiver receives transmissions from each of the tire pressure sensors via an internal antenna. This information is thencommunicated to the via a dedicated Local Interconnect Network (K-bus).CJB

Initiator

The initiators are located at the front of the front wheel arches and at the rear of the rear wheel arches and are secured withtwo scrivets. The TPMS has four initiators and each has a connector which connects with the body harness.

The initiator is a passive, Low Frequency (LF) transmitter. Each initiator provides an auto-location feature to identify tirepositions on the vehicle and transmit that data to the .CJB

The energizes each initiator in turn using LF drivers. The corresponding tire pressure sensor detects the resulting LFCJBtransmission and responds by initiating an RF transmission of its data. This data is received by the RF receiver andcommunicated to the via a K-bus. The can then determine which sensor is transmitting and its location on theCJB CJBvehicle.

Tire Pressure Sensor

The TPMS system uses ‘active’ tire pressure sensors which are mounted on each wheel, inside the tire cavity. The sensor isretained in position by the valve attachment to the wheel structure. The sensors transmit their RF signals at either 315 MHz or433 MHz dependent on market requirements.

The sensors periodically measure the pressure and temperature of the air inside the tire plus the centripetal accelerationacting on the sensor. These measurements are transmitted periodically to the RF receiver located behind the overheadconsole.

The tire pressure sensors are self-contained units which have no electrical connections into or out of the sensor.

The care points detailed in the 'Tires' section of this chapter must be followed to avoid damage to the sensor. If the sensor isreplaced, the nut, seal and washer must also be replaced and the sensor tightened to the correct torque value as given in theService Repair manual.

The RF transmission from the sensor contains a unique identification code in its transmission data, so that the can identifyCJBthe tire on the vehicle. If the sensor is replaced on a 'running' wheel, the new sensor identification will be learnt when the

Item

vehicle is first driven at a speed of more than 12.5 mph (20 km/h) for 15 minutes. If a new sensor is fitted to the sparewheel, the identification for that sensor must be programmed into the using a Land Rover approved diagnostic system orCJBthat wheel will not be monitored. The code is provided on a label with the complete wheel and tire assembly when new and isalso printed on the casing of each sensor.

The replacement spare wheel may also be programmed to the vehicle by using it as a 'running' wheel for 15 minutes at morethan 12.5 mph (20 km/h), then replacing it to the spare wheel position.

In order to conserve battery power, the tire sensor module uses different transmission rates when the wheel is stationary ormoving. The wheel speed required to change between the stationary and moving transmission rates is very low to allow forthe requirement for slow off-road driving.

Instrument Cluster Indications

Description

Amber warning indicator

Message center

The warning indications to the driver are common on all vehicles fitted with TPMS. Warnings are conveyed by an amber lightemitting diode (LED) warning indicator and a text message displayed in the message center.

The warning indicator and message center are driven by CAN messages from the . The warning indicator is illuminated byCJBthe cluster software for 3 seconds when the vehicle is in power mode 6 for a bulb check.

For additional information, refer to: (413-08 Information and Message Center, DescriptionInformation and Message Centerand Operation).

Controller Area Network (CAN)

The sends and receives a number of digital messages via the medium speed controller area network (CAN). The receivedCJBmessages are used for the operation of the TPMS. The transmitted messages comprise of TPMS status and requests to theinstrument cluster to illuminate warnings indicators and/or display messages in the message center.

Transmitted Messages

The transmits the messages shown in the following table.CJB

Message Received ByTPMS diagnostic response A Land Rover approved diagnostic system.TPMS amber warning indicator request at 25% tire deflation Instrument clusterTPMS message display request Instrument cluster

Diagnostics

The has a diagnostic connection via the medium speed CAN to enable system status and faults to be retrieved using aCJBLand Rover approved diagnostic system.

Additionally, an on-board diagnostic routine within the constantly monitors the system and alerts the driver to systemCJBfaults by illuminating the amber warning indicator and/or displaying a message in the instrument cluster message center.

Fault Detection

If a sensor fails, the amber warning indicator in the instrument cluster will be illuminated. A message 'XX Tyre Not Monitored'will be displayed in the message center in addition to the amber warning indicator.

NOTE: 'XX' is the tire position on the vehicle, e.g. FL (front left), FR (front right), RL (rear left) or RR (rear right).

If more than one sensor fails or the develops a fault, the amber warning indicator will be illuminated. A message 'TyreCJBMonitoring System Fault' will be displayed in the message center in addition to the amber warning indicator. This fault couldalso be caused if RF interference near the vehicle affects the system signal reception. When the interference has ceased, thefault will be automatically cancelled and the TPMS will operate normally.

If a tire pressure sensor battery voltage becomes low, the sensor transmits a message to the . The stores the lowCJB CJBbattery condition as a fault flag in its memory with no other visual warnings displayed. If the battery fails, the sensor will stoptransmitting and the will transmit a message to display 'FL Tyre Not Monitored' for example in the message center. TheCJBdealer should interrogate the for the fault flag using a Land Rover approved diagnostic system to determine the cause ofCJBthe message. If the battery has failed, the sensor must be replaced and the stored fault flags removed using a Land Roverapproved diagnostic system. The will learn the identification of the new sensor when the vehicle is driven. If the replacedCJBsensor is fitted to the spare wheel (if fitted), its identification must be manually programmed into the using a Land RoverCJBapproved diagnostic system or by using it as a 'running' wheel for 15 minutes at more than 12.5 mph (20 km/h), thenreplacing it to the spare wheel position.

CAUTION: Diagnosis by substitution from a donor vehicle is acceptable. Substitution of control modules does not NOTguarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.

NOTES:

If a control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty Policy and Procedures manual, or determine if any prior approval programme is in operation, prior to the installationof a new module/component.

Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by themanufacturer-approved diagnostic system).

When performing voltage or resistance tests, always use a digital multimeter accurate to three decimal places, and with an up-to-date calibration certificate. When testing resistance always take the resistance of the digital multimeter leads intoaccount.

Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.

Inspect connectors for signs of water ingress, and pins for damage and/or corrosion.

If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the cause. Always check for loose connections and corroded terminals.
