A7 CHECK THE DRIVER SAFETY BELT RETRACTOR PRETENSIONER DEPLOYMENT CONTROL DTC (DIAGNOSTIC TROUBLE CODE) FOR A FAULT STATUS CHANGE (OPEN INDICATED)

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.

Connect RCM C310A and C310B. Connect a fused jumper wire:

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 retractor pretensioner circuits shorted together, a low resistance fault is normally retrieved.
