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 driver safety belt anchor pretensioner circuits shorted together, a low resistance fault is normally retrieved.

Yes | REMOVE the fused jumper wire and GO to A11 |
|---|---|
No | REMOVE the fused jumper wire and GO to A12 |
