Description And Operation: Description: Diagnostics
WARNING: This page is about a different car, the 2018 Jaguar XE and 2017 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
The TPM module has a diagnostic connection through the CAN Bus which allows a Jaguar-approved diagnostic system to retrieve the system status and faults.
Additionally, an on-board diagnostic routine within the TPM module constantly monitors the system and alerts the driver to system faults by turning on the amber warning indicator and/or displaying a message in the IC message center.
