- Disconnect left front door lock motor connector. Connect test light between door lock motor connector terminals. Using scan tool, actuate left lock relay. If test light flashes when left lock relay is actuated, replace left door lock motor. If test light does not flash when left lock relay is actuated, go to next step.
- Using scan tool in ohmmeter mode, backprobe terminal No. 6 (Orange/Violet wire) on driver's door module 12-pin connector. See Fig 1 . If resistance is more than 20 ohms, replace driver's door module. If resistance is 20 ohms or less, go to next step.
- Using scan tool in ohmmeter mode, backprobe terminal No. 5 (Pink/Black wire) on driver's door module 12-pin connector. If resistance is more than 20 ohms, replace driver's door module. If resistance is 20 ohms or less, go to next step.
- Using test light, backprobe terminal No. 6 (Orange/Violet wire) on driver's door module 12-pin connector. Using scan tool, actuate left door lock relay. If test light does not flash when left door lock relay is actuated, replace driver's door module. If test light flashes when left door lock relay is actuated, go to next step.
- Using test light, backprobe terminal No. 5 (Pink/Black wire) on driver's door module 12-pin connector. Using scan tool, actuate left door unlock relay. If test light does not flash when left door unlock relay is actuated, replace driver's door module. If test light flashes when left door unlock relay is actuated, go to next step.
- Using test light, probe terminal No. 2 (Orange/Violet wire) on left door lock motor connector. Using scan tool, actuate left door lock relay. If test light does not flash when left door lock relay is actuated, repair open in Orange/Violet wire. If test light flashes when left door lock relay is actuated, repair open in left front door unlock driver circuit (Pink/Black wire).
