- If problem is with unlock function, go to step 4). If problem is not with unlock function, turn ignition off. Gain access to inoperative door lock switch.
- Disconnect Blue body controller connector. Body controller is located under left side of instrument panel. Using an external ohmmeter, measure resistance of switched battery feed circuit between Blue body controller connector terminal No. 8 (Orange/Violet wire) and power lock switch Orange/Violet wire.
- If resistance is more than 5 ohms, repair open Orange/Violet wire. If resistance is less than 5 ohms, replace open door lock switch.
- Turn ignition off and gain access to inoperative door lock switch. Using an external ohmmeter, measure resistance of switched battery feed circuit between door unlock relay connector terminal No. 14 (Pink/Violet wire) and power lock switch Pink/Violet wire.
- If resistance is more than 5 ohms, repair open Pink/Violet wire. If resistance is less than 5 ohms, replace open door lock switch.
