Door Key Lock & Unlock Switch Circuit
- Remove door trim panel and service hole cover to access door key lock cylinder (door key lock and unlock switch is built into door key lock). Disconnect 3-pin door key lock and unlock switch connector. Using an ohmmeter, check continuity between switch connector terminals No. 1 (Green wire on left door; Green/White wire on right door), No. 2 (White/Black wire) and No. 3 (Green/Yellow wire) with switch in specified position. See DOOR KEY LOCK & UNLOCK SWITCH CONTINUITY table. If continuity is as specified, go to next step. If continuity is not as specified, replace door key lock and unlock switch.DOOR KEY LOCK & UNLOCK SWITCH CONTINUITY

See WIRING DIAGRAMS . Repair or replace as necessary. If circuits are okay, check anti-theft/door lock control ECU pin voltages. See ANTI-THEFT/DOOR LOCK CONTROL ECU PIN VOLTAGE TESTS under COMPONENT TESTS. Replace as necessary and retest system operation. Proceed to next test listed in appropriate SYMPTOM DIAGNOSIS table under TROUBLE SHOOTING .
