Height Sensor - Operation

OPERATION

If equipped with an air suspension system, the height sensors are wired directly to the Air Suspension Control Module (ASCM) where information is used to determine and control vehicle height. The ASCM then transmits the information on the CAN bus where it is used by the Auto Headlamp Leveling Module (AHLM). If not equipped with air suspension, but is equipped with headlamp leveling, the sensors are wired directly to the AHLM. The sensors have three wired circuits for height sensor power, signal and return.
