With the ignition ON, the IPC sends messages to the ABS module through the GWM over the HS-CAN 3. If the ABS module does not receive these messages within a certain time frame, the module sets DTCs. For information on the messages sent to the ABS module by the IPC, refer to the Network Message Chart in Description and Operation in the Anti-Lock Brake System (ABS) and Stability Control article.
