NOTE: Make sure all SRS components and the RCM electrical connectors are connected before carrying out the self-test. If not, Diagnostic Trouble Codes (DTCs) will be recorded.
Connect RCM C310A and C310B. Repower the SRS. Do not prove out the SRS at this time. REFER to: Supplemental Restraint System (SRS) Repowering (501-20B Supplemental Restraint System, General Procedures). Ignition ON. Using a diagnostic scan tool, clear all RCM Diagnostic Trouble Codes (DTCs). Using a diagnostic scan tool, perform RCM self-test.
Was the original DTC retrieved on-demand during self-test?
Yes | CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new RCM. REFER to: Restraints Control Module (RCM) (501-20B Supplemental Restraint System, Removal and Installation). GO to A6 |
|---|---|
No | In the process of diagnosing the fault, the fault condition has become intermittent. Do not install any new SRS components at this time. Install SRS components only when directed to do so in the pinpoint test. GO to A5 |
A5 CHECK THE HARNESS AND CONNECTORS
Ignition OFF. Depower the SRS. REFER to: Supplemental Restraint System (SRS) Depowering (501-20B Supplemental Restraint System, General Procedures). Disconnect RCM C310A and C310B. Inspect RCM C310A and C310B Connector Position Assurance (CPA) lever/lock for correct operation. Inspect RCM C310A and C310B for pushed-out, loose or spread terminals and loose or frayed wire connections at terminals. Inspect wire harnesses for any damaged, pinched, cut or pierced wires.
Were any concerns found?
Yes | REPAIR as necessary. Refer to Wiring Diagrams Cell 5 for schematic and connector information. GO to A6 |
|---|---|
No | The fault is not present and cannot be recreated at this time. Do not install any new SRS components at this time. Install SRS components only when directed to do so in the pinpoint test. GO to A6 |
A6 CHECK FOR ADDITIONAL SRS (SUPPLEMENTAL RESTRAINT SYSTEM) DIAGNOSTIC TROUBLE CODES (DTCS)
