Diagnostic Instructions

The symptom chart can be used to help locate SRS concerns if no DTCs are retrieved and the listed symptoms are observed. Whether or not the listed symptoms are observed, always carry out the following:

1. Run the Self Test to determine what on-demand and continuous memory DTCs are being sensed by the RCM and OCSM.

2. Retrieve all SRS DTCs and fault PIDs stored in the RCM and OCSM memory.

3. If on-demand DTCs are different than continuous memory DTCs, always diagnose the on-demand DTCs first.

A DTC can indicate several concerns. The DTCs are to assist in system diagnosis and are not to be considered definitive. Always refer to the pinpoint test corresponding to the DTC to determine where the concern lies and to repair the concern correctly.
