With the ignition ON, the RCM sends messages to the SECM over the HS-CAN 2 and through the SASM. 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 RCM, refer to the Network Message Chart in the Description and Operation in  Power Steering System  .
