Normal Operation and Fault Conditions
With the ignition ON, the BCM sends messages to the ABS module over the HS-CAN. If the ABS module does not receive these messages within the specified time frame, the ABS module sets DTCs. This can be due to a BCM failure, a circuit failure on the HS-CAN or an excessive load on the network. For information on the messages sent to the ABS module by the BCM, Anti-Lock Control .
