Normal Operation and Fault Conditions

With the ignition ON, the BCM sends messages to the SASM over the HS-CAN. If the SASM does not receive these messages within the specified time frame, the module sets a DTC. This can be due to a BCM failure, a circuit failure on the HS-CAN or an excessive load on the network. For information on the cruise control messages sent to the SASM by the BCM, refer the  DESCRIPTION AND OPERATION  .
