Normal Operation and Fault Conditions
With the ignition ON, the AWD module sends messages to the ABS module through the GWM 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 AWD module, refer to the Description and Operation in Anti-Lock Brake System (ABS) and Stability Control article.
