article in ENGINE PERFORMANCE. Perform TEST VER-1 after each repair.
- Gain access to Remote Keyless Entry (RKE) module, located behind rear seat. Ensure front windows are down and left front door is closed. Turn ignition off. Disconnect RKE module Black connector. Go to next step.
- Using scan tool in ohmmeter mode, check resistance of RKE module Black connector terminal "H" (Black wire). If resistance is more than 5 ohms, repair open Black wire. If resistance is less than 5 ohms, go to next step.
- Turn ignition on. Using scan tool in voltmeter mode, check voltage on RKE module Black connector terminal "A" (Pink wire). If voltage is less than 10 volts, repair open Pink wire. if voltage is more than 10 volts, go to next step.
- Check voltage on RKE module Black connector terminal "G" (Dark Blue wire) while depressing door lock switch to LOCK position. If voltage is more than 10 volts when door lock switch is depressed, replace RKE module. If voltage is less than 10 volts, go to next step.
- Connect a jumper wire between RKE module Black connector terminal "G" (Dark Blue wire) and terminal "H" (Black wire). Remove left door panel. Disconnect door lock motor connector. Go to next step.
- Using scan tool in ohmmeter mode, check resistance on door lock motor connector terminal No. 2 (Dark Blue wire on left door; Light Green wire on right door). If resistance is more than 5 ohms, repair open Dark Blue wire or Light Green wire. If resistance is less than 5 ohms, go to next step.
- Using scan tool in voltmeter mode, check voltage on door lock motor connector terminal No. 1 (Orange/Black wire) while depressing right door lock switch to LOCK position. If voltage is less than 10 volts when door lock switch is depressed, repair open Orange/Black wire. If voltage is more than 10 volts, replace left door lock motor.
