Test E: The Chime Sounds When The Driver Door Is Ajar (No Key In Ignition And Headlamps Off)

PINPOINT TEST E: THE CHIME SOUNDS WHEN THE DRIVER DOOR IS AJAR (NO KEY IN IGNITION AND HEADLAMPS OFF)

Normal Operation
When the key is inserted into the ignition lock cylinder, the key-in-ignition switch (part of the ignition switch) closes circuit 1716 (GY/YE) and circuit 158 (BK/PK) to the lighting control module (LCM), providing a voltage signal. The voltage input signals the LCM that the key is inserted. If the LCM detects that the ignition switch is in the OFF or ACC position, the key is inserted in the ignition lock cylinder, and the driver door is ajar, the key-in-ignition warning chime sounds.

The LCM monitors the headlamp switch input and the driver door ajar switch input, sounding a chime if the driver door is open, the parking lamps are on, and the ignition switch is not in the ON position.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Key-in-ignition switch (part of the ignition switch)
- LCM
