Air Suspension System

The air suspension system provides a fully automatic self leveling function that makes sure the vehicle maintains a constant attitude, irrespective of load. The air suspension system adjusting the rear ride height to match the front ride height.

The air suspension system is electronically controlled by the Chassis Control Module (CHCM).

The air suspension system maintains the vehicle height under all operating conditions by controlling the mass of air in the air springs. The CHCM uses signals from the 4 height sensors to maintain the correct suspension height, irrespective of vehicle load.

The system will temporarily inhibit height adjustments when the vehicle is subject to cornering, heavy acceleration or heavy braking. The inhibit function prevents unsettling of the vehicle.

The CHCM performs 'on board diagnostic' functions to perform 'health checks' on the system. If faults are detected, codes are stored in the control module and can be retrieved using a Jaguar Land Rover approved diagnostic equipment.
