Fault Detection

If a sensor fails, the amber warning indicator in the Instrument Cluster (IC) flashes and then stays on and a message 'XX Tire Pressure Not Monitored' appears in the IC message center.

NOTE: 'XX' means the wheel position on the vehicle as follows:

Front left
Front right
Rear left
Rear right

If more than one sensor fails or the TPMS develops a system fault, the amber warning indicator flashes for 75 seconds and then stays on and a message 'Tire Pressure Monitoring System Fault' appears in the message center. This fault could also happen if RF interference near the vehicle affects the signal reception of the system. When the interference stops, the fault is automatically cancelled and the TPMS operates normally.

If a tire pressure sensor battery fails, the sensor stops transmitting and, after the missing sensor timer expires, the TPMS transmits a message to display 'FL Tire Pressure Not Monitored' for example in the message center. You must interrogate the TPMS using a Land Rover approved diagnostic system to determine the cause of the message. If the sensor has failed, you must replace it and remove the stored fault flags using a Jaguar-approved diagnostic system.
