Normal Operation And Fault Conditions
With the ignition ON, the SCCM sends messages to the SECM, through the SASM and over the HS-CAN 2. If the SECM does not receive these messages within a certain time frame, the SECM sets a DTC. For information on the messages sent to the SECM by the SCCM, refer to the Network Message Chart in Description and Operation of the Power Steering article.
