Normal Operation and Fault Conditions 

With the ignition ON, the IPC sends messages to the GWM over the HS-CAN3, the GWM relays these messages to the ABS module over the HS-CAN2. If the ABS module does not receive these messages within the specified time frame, the module sets a DTC. This can be due to a GWM failure, an IPC failure, a circuit failure on the network or an excessive load on the network. For information on the messages sent to the ABS module by the IPC, REFER to: Anti-Lock Brake System (ABS) and Stability Control - System Operation and Component Description .

DTC Fault Trigger Conditions
