With the ignition ON the SCCM sends steering angle and windshield wiper status messages to the ABS module over the HS-CAN 2. If the ABS module does not receive these messages within the specified time frame or if the data contains invalid data, the ABS module sets a DTC. This can be due to a SCCM failure, a circuit failure on the network or an excessive load on the network. For information on the messages sent to the ABS module by the SCCM, refer to the Network Message Chart in Description and Operation of the Anti-Lock Brake System (ABS) and Stability Control article.
