With the ignition ON, the IPC sends messages to the GWM over the HS-CAN 3, the GWM relays these messages to the ABS module over the HS-CAN 2. 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 the Network Message Chart in Anti-Lock Brake System (ABS) and Stability Control article.
