Normal Operation and Fault Conditions
With the ignition ON, the BCM sends messages to the ABS module through the GWM over the HS-CAN 1. If the ABS module does not receive these messages within a certain time frame, the module sets DTCs. For information on the messages sent to the ABS module by the BCM, refer to the Network Message Chart in DESCRIPTION AND OPERATION .
