Normal Operation and Fault Conditions
With the ignition ON, the SASM sends messages to the SCCM over a private CAN. The SCCM relays these messages to the ABS module over the HS-CAN 2. If the ABS module does not receive these messages within a certain time frame, the ABS module sets a DTC. For information on the messages sent to the ABS module by the SASM, refer to the Description and Operation in Anti-Lock Brake System (ABS) And Stability Control .
