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 A9 |
|---|---|
No | In the process of diagnosing the fault, the fault condition has become intermittent. Do not install any new SRS components at this time. SRS components should only be installed when directed to do so in the pinpoint test. GO to A8 |
A8 CHECK FOR AN INTERMITTENT FAULT
Ignition OFF. Depower the SRS. REFER to: Supplemental Restraint System (SRS) Depowering (501-20B Supplemental Restraint System, General Procedures). Disconnect BCM C2280E. Disconnect RCM C310A and C310B.
inspect connector(s) (including any inline connectors) for loose or spread terminals and loose or frayed wire connections at terminals. inspect wire harness for any damage, pinched, cut or pierced wires. repair any concerns found. Refer to Wiring Diagrams Cell 5 for schematic and connector information.
Connect BCM C2280E. 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, perform the RCM self-test to retrieve Diagnostic Trouble Codes (DTCs).
Was DTC B11D8:12 or B11D8:14 retrieved on-demand during self-test?
Yes | The fault condition is now present. This fault cannot be cleared until it is corrected and the DTC is no longer retrieved on-demand during the self-test. For DTC B11D8:14, GO to A2 For DTC B11D8:12, GO to A5 |
|---|---|
No | CHECK for causes of the intermittent fault. ATTEMPT to recreate the hard fault by flexing the wire harness and cycling the ignition frequently. ACTIVATE other systems in the same wire harness. Do not install any new SRS components at this time. Only install SRS components when directed to do so in the pinpoint test. REPAIR any intermittent concerns found. GO to A9 |
A9 CHECK FOR ADDITIONAL SRS (SUPPLEMENTAL RESTRAINT SYSTEM) DIAGNOSTIC TROUBLE CODES (DTCS)
Ignition OFF. Reconnect all connectors (if previously disconnected). If previously directed to depower the SRS, 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.
