Normal Operation and Fault Conditions
With the ignition ON, the ABS module 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 ABS module, go to the Module Network Input Messages - VDM. REFER to: Vehicle Dynamic Suspension - System Operation and Component Description (204-05 Vehicle Dynamic Suspension, Description and Operation).
