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 TCCM, refer to the Description and Operation in the Anti-Lock Brake System (ABS) and Stability Control article.
