- 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 set in ohmmeter mode, backprobe driver's door module 12-pin connector terminal No. 6 (Orange/Violet wire). 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 driver's door module 12-pin connector terminal No. 5 (Pink/Black wire). 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 driver's door module 12-pin connector terminal No. 6 (Orange/Violet wire). Using scan tool, actuate left door lock relay.
