- NO : CHECK for causes of the intermittent fault. ATTEMPT to recreate the hard fault by flexing the wire harness and cycling the ignition key frequently. ACTIVATE other systems in the same wire harness. Do not install any new SRS components at this time. SRS components should only be installed when directed to do so in the pinpoint test. REPAIR any intermittent wiring, terminals or connector concerns found. Go to K39.
- K39 CHECK FOR ADDITIONAL SRS DTCs
- Key in OFF position.WARNING: Turn the ignition OFF and wait one minute to deplete the backup power supply. Failure to follow this instruction may result in serious personal injury or death in the event of an accidental deployment.
- Reconnect all SRS components (if previously disconnected).
- If previously directed to depower the SRS, repower the SRS. Do not prove out the SRS at this time. Refer to Supplemental Restraint System (SRS) Depowering and Repowering .
- Key in ON position.
- Enter the following diagnostic mode on the diagnostic tool: Self Test - RCM
- Are any on-demand DTCs retrieved?
- YES : Do not clear any DTCs until all DTCs have been resolved. Go to the SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DIAGNOSTIC TROUBLE CODE INDEX for pinpoint test direction.
- NO : CLEAR all RCM continuous memory DTCs. PROVE OUT the SRS. REPAIR is complete. RETURN the vehicle to the customer.
- Key in OFF position.
