THEORY OF OPERATION
The Active Damping Control Module (ADCM) detects the Damping Mode button switch information by receiving messages from the CAN communications bus. Specifically the UP button is wired to the cluster, the cluster sends this information via CAN I to the TIPM, and TIPM sends it onto the ADCM via CAN C.

The Active Damping Control Module (ADCM) continuously monitors the vehicle's VIN (from the CAN bus) and compares it to the VIN which is internally stored within the ADCM when the vehicle was first assembled. When they do not match this fault sets.
The Active Damping Control Module (ADCM) continuously monitors internal hardware circuitry for defects. The Service Air Suspension Message will be displayed on the cluster when this fault is first active.
The Steering Angle Sensor (SAS) communicates with other controllers over the CAN C bus. The Active Damping Control Module (ADCM) continuously monitors the bus activity and receives the messages it needs. If the ADCM does not receive messages from the Steering Angle Sensor (SAS), this fault will set.
