Diagnostics
The TPMS module has a diagnostic connection via the medium speed CAN to enable system status and faults to be
retrieved using T4.
Additionally, an on-board diagnostic routine within the TPMS module constantly monitors the system and alerts the driver to
system faults by illuminating the amber warning indicator, emitting a tone from the instrument cluster sounder and/or
displaying a message in the instrument cluster message center.
Fault Detection
If a sensor fails, the amber warning indicator in the instrument cluster will be illuminated. A message 'XX Tyre Pressure Not
Monitored' will be displayed in the message center in addition to the amber warning indicator.
If more than one sensor fails or the TPMS module develops a fault, the amber warning indicator will be illuminated. A
message 'Tyre Pressure Monitoring System Fault' will be displayed in the message center in addition to the amber warning
indicator. This fault could also be caused if RF 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 voltage becomes low, the sensor transmits a message to the TPMS module. The module
stores the low battery condition as a fault flag in its memory with no other visual warnings displayed. If the battery fails, the
sensor will stop transmitting and the TPMS module will transmit a message to display 'FL Tyre Not Being Monitored' for
example in the message center. The dealer should interrogate the TPMS module using T4 for the fault flag to determine the
cause of the message. If the battery has failed the sensor must be replaced and the stored fault flags removed using T4.
