Theory Of Operation

WARNING: This page is about a different car, the 2015 RAM 3500 HD and 2015 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

The Air Suspension Control Module (ASCM) communicates with other controllers over the CAN C bus. The ASCM continuously monitors the bus activity and receives the messages it needs. If the ASCM does not receive messages from the SAS, then this fault will set. The Service Air Suspension Message will be displayed on the cluster when this fault is first active.
