Normal Operation and Fault Conditions
With the ignition ON, the RCM sends messages to the VDM over the HS-CAN2. If the VDM does not receive these messages within a certain time frame, the module sets Diagnostic Trouble Codes (DTCs). For information on the messages sent to the VDM by the RCM, refer to Network Message Chart . Refer to: Vehicle Dynamic Suspension - System Operation and Component Description .
