Normal Operation and Fault Conditions

With the ignition ON, the GWM sends 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 DTCs. For information on the messages sent to the ABS module by the GWM, refer to the NETWORK MESSAGE CHART in Description and Operation of Anti-Lock Brake System (ABS) and Stability Control article.
