CAUTION:
Always turn ignition off prior to disconnecting or connecting any module connector.

For connector terminal identification, see CONNECTOR IDENTIFICATION in this article. For appropriate wiring diagram, see WIRING DIAGRAMS section at the end of this article. Perform TEST VER-1B after each repair.
- Turn ignition off. Disconnect Body Control Module (BCM) Blue connector. BCM is located behind left side knee panel. If key-in lamp goes out, replace BCM. If key-lamp stays on, go to next step.
- Disconnect key-in lamp switch 4-pin connector. Using scan tool in ohmmeter mode, check resistance of key-in lamp switch connector terminal No. 4 (Yellow/Red wire). If resistance is less than 5 ohms, repair Yellow/Red wire for short to ground. If resistance is more than 5 ohms, replace ignition switch.
