Normal Operation and Fault Conditions
With the ignition ON, the TCCM sends messages to the GWM over the HS-CAN1, the GWM relays these messages to the ABS module over the HS-CAN 2. If the ABS module does not receive these messages within a certain time frame (usually less than 1 second), the ABS module sets a DTCs. For information on the messages sent to the ABS module by the TCCM, refer to the Description and Operation in the Anti-Lock Brake System (ABS) and Stability Control article.
