With the ignition ON, the CCM sends messages to the ABS module over the FD-CAN. 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 CCM refer to the Network Message Chart in Description and Operation of the Anti-Lock Brake System (ABS) and Stability Control article.
