Normal Operation and Fault Conditions
With the ignition ON, the BCM sends messages to the GWM over the HS-CAN 1. The GWM sends these messages to the VDM over the HS-CAN 2. 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 BCM, go to the Network Message Chart. REFER to: Vehicle Dynamic Suspension - System Operation and Component Description .
