There are 4 height sensors are used in the Adaptive Damping (AD) system, 2 for the front suspension and 2 for the rear suspension. The front suspension height sensor is attached with a bracket to the inside of the suspension top mount on each side. The height sensors are connected by a sensor arm and sensor link to the related upper control arm of the front suspension.

The rear suspension height sensor is attached to each side of the rear subframe. The sensor is connected by a sensor arm and sensor link to the related lower control arm of the rear suspension.

On each suspension height sensor, the sensor arm and sensor link convert linear movement of the suspension into rotary movement of the sensor shaft. The suspension height sensors measure suspension displacement at each corner of the vehicle and output a corresponding analogue signal to the Chassis Control Module (CHCM). The algorithms in the CHCM calculate the position, velocity and frequency content of the signals and use the results for wheel control.

Each suspension height sensor is connected to the CHCM via 3 wires, which supply ground, 5V supply and signal return.
