Fault Detection

If a sensor fails, the amber warning indicator in the Instrument Cluster (IC) will be illuminated. A message 'XX Tire Not Monitored' will be displayed in the message center in addition to the amber warning indicator.

NOTE: 'XX' denotes the tire position on the vehicle:

FL (front left)
FR (front right)
RL (rear left)
RR (rear right).

If more than one sensor fails or the TPMS develops a fault, the amber warning indicator will be illuminated and a message 'Tire Monitoring System Fault' will be displayed in the message center. This fault could also be caused if Radio Fre interference near the vehicle affects the system signal reception. When the interference has ceased, the fault will be automatically cancelled and the TPMS will operate normally.

If a tire pressure sensor battery fails, the sensor will stop transmitting and the TPMS will transmit a message to display 'FL Tire Not Monitored' for example in the message center. The dealer should interrogate the TPMS using a Jaguar Land Rover approved diagnostic system to determine the cause of the message. The TPMS wheel unit maybe in 'Ship' mode and a handheld Low Frequency Tool can be used to turn the TPMS wheel unit on into 'Park' mode. If the sensor has failed, the sensor must be replaced and the stored fault flags removed using a Jaguar Land Rover approved diagnostic system.
