Normal Operation and Fault Conditions
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 Description and Operation in Anti-Lock Brake System (ABS) And Stability Control .
