Normal Operation and Fault Conditions

With the ignition ON, the SASM sends adaptive front steering 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. This can be due to a steering angle sensor failure, a circuit failure on the HS-CAN 2 or an excessive load on the network. For information on the messages sent to the ABS module by the SASM, refer to the Description and Operation in the Anti-Lock Brake System (ABS) and Stability Control article.
