Chassis Control Module
The Chassis Control Module (CHCM) is the main controller of the air suspension system. The CHCM monitors the height of each corner of the vehicle via four height sensors, which are mounted in-board of each road wheel. The CHCM is fixed to a bracket behind the trim on the right side of the luggage compartment with three nuts.
When a new CHCM is fitted, the air suspension software should be loaded and the system calibrated using a Jaguar Land Rover approved diagnostic tool. The air suspension system will not function until the calibration is completed.
