Normal Operation and Fault Conditions
With the ignition ON, the RCM sends messages to the VDM over the HS-CAN2. If the VDMdoes 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, go to the Network Message Chart. REFER to: Vehicle Dynamic Suspension - System Operation and Component Description .
