A5 CHECK THE DRIVER FRONTAL STAGE 1 DEPLOYMENT CONTROL DTC (DIAGNOSTIC TROUBLE CODE) FOR A FAULT STATUS CHANGE (LOW RESISTANCE INDICATED) (CLOCKSPRING DISCONNECTED)
NOTE: This pinpoint test step attempts to change the fault reported by the RCM by inducing a different fault condition. If the reported fault changes, this indicates the RCM is functioning correctly and is not the source of the fault. Ignition OFF. Depower the SRS. REFER to: Supplemental Restraint System (SRS) Depowering (501-20B Supplemental Restraint System, General Procedures). Disconnect Clockspring C218A. 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. DIAGNOSTIC TIP: When viewing Diagnostic Trouble Codes (DTCs) with the clockspring disconnected, open circuit faults are normally retrieved on stages 1 and 2.

No | GO to A7 |
A7 CHECK THE RCM (RESTRAINTS CONTROL MODULE) FOR LOW RESISTANCE
Depower the SRS. REFER to: Supplemental Restraint System (SRS) Depowering (501-20B Supplemental Restraint System, General Procedures). Disconnect RCM C310A and C310B. Measure:
Positive Lead | Measurement / Action | Negative Lead |
|---|---|---|
C310A, pin 29, component side | C310A, pin 30, component side |
Is the resistance greater than 10,000 ohms?
Yes | REPAIR the driver airbag stage 1 circuit(s) for a short together. Refer to Wiring Diagrams Cell 5 for schematic and connector information. GO to A24 |
