Fault Detection

WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

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

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

Front left
Font right
Rear left
Rear right.

If more than 1 TPMS sensor fails or the TPMS develops a system fault, the amber warning indicator flashes for 75 seconds. The warning indicator then stays on and a message 'Tire Pressure Monitoring System Fault' appears in the message center. A fault could also happen if Radio Frequency (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 TPMS sensor battery fails, the TPMS sensor stops transmitting. After the missing TPMS sensor timer expires, the TPMS transmits a message to the message center to display for example, 'FL Tire Pressure Not Monitored'. The TPMS must be interrogated using the Jaguar Land Rover (JLR) approved diagnostic equipment to determine the cause of the message. If the TPMS sensor has failed, it must be replaced and the warning indicator must be turned off using the JLR approved diagnostic equipment.
