Normal Operation and Fault Conditions
With the ignition ON, the SECM sends messages to the SASM over a private CAN. If the SASM does not receive these messages within a certain time frame (usually less than 1 second), the SASM sets DTCs. For information on the messages sent to the SASM by the SECM, refer to the Network Message Chart in DESCRIPTION AND OPERATION .
