Normal Operation and Fault Conditions
With the ignition ON, the SASM sends messages to the ABS module over the HS-CAN. If the ABS module does not receive these messages within a specified 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 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 ANTI-LOCK BRAKE SYSTEM (ABS) AND STABILITY CONTROL .
