  1. Check Door Key Lock & Unlock Switch Operation

    Check door key lock and unlock switch operation. See DOOR KEY LOCK & UNLOCK SWITCH  under COMPONENT TESTS. If door key lock and unlock switch operates properly, go to next step. If door key lock and unlock switch is defective, replace door key lock and unlock switch.

See WIRING DIAGRAMS . Anti-theft system ECU is located near passenger's side of instrument panel, behind glove box, just above kick panel and uses a 12-pin electrical connector and a 22-pin electrical connector. See Figure.
