Wheel Unit Investigation

Ask the customer if they have used additional accessories in the vehicle such as: USB chargers, insurance cameras, DC-DC converters, cool boxes, satellite navigation and radar detectors when the TPMS fault light came on. If yes, ask the customer to remove the items, and see if the TPMS fault light does not come on.

Break the bead and inspect the TPMS wheel unit and compare the wheel unit ID, with the wheel ID as read by the approved Jaguar Land Rover diagnostic tool. If the TPMS wheel IDs are different, program the new wheel ID into the approved Jaguar Land Rover diagnostic tool, and run the deflation test. Make sure the TPMS wheel unit is working.

If the TPMS wheel unit is not detected with the new wheel unit, then ask the customer where the TPMS wheel unit was purchased. The wheel unit is in ship mode, and needs to be put into park mode with a LF tool. Jaguar Land Rover will not pay the warranty for this claim, this is not a manufacturing defect.
