Install the driver airbag (if previously removed). REFER to: Driver Airbag (501-20B Supplemental Restraint System, Removal and Installation). Connect Clockspring C218A (if previously disconnected). Connect RCM C310A and C310B (if previously disconnected). 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.
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 A23 |
|---|---|
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. For DTC B0002:13 or B0002:1A, GO to A19 For DTC B0002:11, GO to A20 For DTC B0002:12, GO to A21 |
A19 CHECK THE DRIVER FRONTAL STAGE 2 DEPLOYMENT CONTROL RESISTANCE (DEPLOY_01_R) PID (PARAMETER IDENTIFICATION) FOR AN INTERMITTENT LOW RESISTANCE OR OPEN CIRCUIT FAULT
Ignition OFF. Remove the steering column shrouds to access the clockspring connectors. REFER to: Steering Column Shrouds (501-05 Interior Trim and Ornamentation, Removal and Installation). Ignition ON. Using a diagnostic scan tool, view RCM Parameter Identifications (PIDs). While monitoring the DEPLOY_01_R PID, attempt to recreate the fault by wiggling connectors (including any inline connectors) and flexing the wire harness, tilting and rotating the steering wheel frequently. Record the resistance value indicated by the PID.
Does the PID value read between 1.62 and 4.46 ohms?
Yes | 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 A22 |
|---|---|
No | If the driver airbag PID indicates incorrect resistance only when the steering wheel is rotated, INSTALL a new clockspring. REFER to: Clockspring (501-20B Supplemental Restraint System, Removal and Installation). For all other faults, DEPOWER the SRS and REPAIR as necessary. Refer to Wiring Diagrams Cell 5 for schematic and connector information. GO to A23 |
