Pinpoint Test BR: Abs Module Communication Concern With VDM
Normal Operation and Fault Conditions
With the ignition ON, the VDM sends messages to the ABS module over the HS-CAN2 through the GWM. If the ABS module does not receive these messages within a certain time frame or if the messages contain invalid data, the ABS module sets Diagnostic Trouble Codes (DTCs). For information on the messages sent to the ABS module by the VDM, refer to Network Message Chart in the service information.

| ABS U0122:00 | Lost Communication With Vehicle Dynamics Control Module: No Sub Type Information | This DTC sets in the ABS module when the dynamic suspension data message from the VDM is missing for at least 5 seconds. |
