Sensor, Height: Operation
WARNING: This page is about a different car, the 2017 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.
The rear height sensors are wired directly to the Air Suspension Control Module (ASCM). The rear vehicle ride height information is used to determine and adjust the rear vehicle ride height. The ASCM then transmits the information to the Air Supply Unit (ASU). The rear height sensors have three wired circuits: height sensor power, signal and return.
