A3 CONFIRM THE RCM (RESTRAINTS CONTROL MODULE) FAULT
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.
Prior to reconnecting any previously disconnected SRS component:
Inspect connector(s) (including any inline connectors) for pushed-out, loose or spread terminals and loose or frayed wire connections at terminals. Inspect wire harness for any damage, pinched, cut or pierced wires. Inspect RCM C310A and C310B Connector Position Assurance (CPA) lever/lock for correct operation. Repair any concerns found. Refer to Wiring Diagrams Cell 5 for schematic and connector information.
Connect all previously disconnected restraint system component(s). 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 RCM self-test.
Were any signal cross coupled Diagnostic Trouble Codes (DTCs) 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 A5 | |
|---|---|---|
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 A4 | |
A4 CHECK FOR AN INTERMITTENT FAULT
NOTE: Most cross link faults are due to connector and/or wiring harness damage. Carry out a thorough inspection of connector(s) and/or wiring harness for damage.
Ignition OFF. Depower the SRS. REFER to: Supplemental Restraint System (SRS) Depowering (501-20B Supplemental Restraint System, General Procedures). Disconnect all of the affected SRS devices. Refer to Wiring Diagrams Cell 46 for schematic and connector information. Inspect the wiring harness(es) for any type of damage. If damage is found, repair as necessary. Refer to Wiring Diagrams Cell 5 for schematic and connector information. 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 RCM self-test.
