Description And Operation: Description: Diagnostics

The Tire Pressure Monitoring Control Module (TPMCM) has a diagnostic connection through the Controller Area Network (CAN) Bus which allows a Land Rover approved diagnostic system to retrieve the system status and faults.

Additionally, an on-board diagnostic routine within the TPMCM 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.
