2.1  Wheel cannot be detected.

Check the wheel(s) to see if a rubber valve has been fitted. If it has replace with a TPMS wheel sensor. Jaguar Land Rover will not pay for the warranty.

If the wheel has a TPMS valve go to section 2.2  .

2.2  TPMS fault messages.

Connect the approved Jaguar Land Rover diagnostic tool and read the Diagnostic Trouble Code(s) (DTC) from the TPMS wheel unit.

2.2.1  NAS markets only.

For NAS markets, please note the TPMS frequency has been set to 433 MHz from 16MY for all vehicles.

2.2.1  EU markets.

EU markets the TPMS system is always 433 MHz.

2.2.2  Wheel unit signals not received from start of a drive cycle.

Possible Causes:

  1. Rubber valve fitted go to section 2.1  .
  2. 315 MHz TPMS wheel unit fitted on a 433 MHz vehicle. (NAS markets Inspect the wheel unit). If a 315 MHz wheel unit is fitted, Jaguar Land Rover will not pay for a replacement.
  3. TPMS wheel unit in ship mode, turned off or customer purchased part. Using a handheld LF tool, turn the TPMS wheel unit on. Jaguar Land Rover will not pay for this as customer purchased.
    • If no TPMS LF hand tool available, then change the TPMS wheel unit to a new one. Jaguar Land Rover will not pay for a replacement, as part not purchased through approved process.
  4. Non Compatible TPMS wheel unit fitted. Inspect wheel unit and check Jaguar Land Rover part number. LocSync systems will only work with FW93 1A159 AA/AB or GX63 1A159 AA.
  5. The TPMS wheel unit battery has failed or the wheel unit has been damaged when tire was replaced.

Replace the identified wheel unit.

NOTE: Please note that Jaguar Land Rover does not cover these cost under warranty, this is not a manufacturing defect.

2.2.3  Wheel units not recognized during a drive cycle.

Possible Causes:

  1. One or more wheels swapped over in less than 15 minutes (winter wheel warehouse replacement).
  2. RF  interference of the TPMS signal from the wheel units to the receiver.
  3. TPMS wheel unit damaged.
  4. Battery failing, (wheel unit over 6 years old).

Go to section 3.0  .

2.2.4  Wheel unit localization.

Check the ABS system for DTC  set. The TPMS system uses the ABS wheel sensor signals to localize the wheel units to the correct wheel location.

The TPMS system needs to receive the RF  transmissions from all four wheel units, to enable the location of the TPMS wheel unit and the TPMS wheel unit ID to be matched. If a rubber valve has been fitted to a wheel, or the TPMS sensor is not transmitting, on the fifth journey and greater than 10 minutes, a localization DTC  will be set.

Make sure all four TPMS wheel units are working using the approved Jaguar Land Rover diagnostic tool deflation test.

If there is RF  interference, this can cause the localization to fail.

Go to section 3.0  .

2.2.5  Incorrect TPMS wheel unit installed.

The vehicle has been fitted with TPMS TG1B wheel sensors that are not compatible with the TPMS system fitted on the vehicle.

New TPMS TG1C wheel sensors are required to be fitted. Jaguar Land Rover will not pay for this warranty.

2.2.6  Low pressure sensor fitted on a high pressure system. Incorrect wheel sensor fitted.

If any of these DTC  are noted, then the tire pressure sensor needs to be changed to a High Pressure wheel unit LR070840.

2.2.7  ECU internal failure.

2.2.8  Controller Area Network (CAN) communication bus missing message.

One or more CAN  frames have not been received from the PCM, ABS, BCM, IPC or GWM. Check the CAN  network, and other ECUs DTC  to work out which ECU has got the fault.

2.2.9  Invalid CAN  signal received.

The signals received are vehicle speed from ABS, ambient temperature from PCM and ambient air pressure from the PCM. Read local snap shot data 0xD020 and the 4 byte code will identify the ECU at fault.

2.2.10  Implausible CAN  signal received.

Read local snap shot data 0xD020 and the 4 byte code will identify the ECU at fault.

2.2.11 CAN  Bus off.

Check the CAN  bus Voltages.

2.2.12 CAN  configuration errors.

No CAN  master configuration ID received.

Flash latest software in to TPMS Module.

2.2.13  Missing local configuration file.

Perform a software update on the TPMS module selecting the correct LCF file.

2.3  Car configuration problems.

Perform a software update on the GWM, and check the configuration for the vehicle is correct.

These DTC  can occur when the wheel or tire size is not compatible with the vehicle.
