Interior Illumination Control

The BCM turns on the courtesy lamps when the following conditions exist:

The BCM turns OFF the courtesy lamps when all the doors are closed and the IP dimmer switch is OFF.

All the vehicle doors contain a door lock ajar switch. When the drivers door is open, the left front door lock ajar switch closes and sends a ground signal to the BCM through circuit 49. When one of the following doors is open:

the corresponding door lock ajar switch closes and sends a ground signal to the BCM through circuit 727. The BCM grounds circuits 156 and 157 when detecting a ground signal in either circuit 49 or 727.

When the drivers door is closed, the left front door lock ajar switch opens circuit 49. When one of the following doors is closed:

the corresponding door lock ajar switches open circuit 727. The BCM then opens circuits 156 and 157 when either circuit 49 or 727 is open.

The BCM uses the voltage in circuit 240 to power the courtesy lamps through circuit 1732. The BCM controls the power supplied in circuit 1732 for inadvertent load (battery rundown) protection. The BCM opens circuits 156 and 157 when the inadvertent load (battery rundown) protection is active, circuit 1732 is open.

Delayed Illumination

The BCM grounds circuits 156 and 157 for 22-28 seconds turning the courtesy lamps ON when the following conditions exist:

The detailed illumination feature is canceled when the following conditions are met:

Exit Illumination

The BCM grounds circuits 156 and 157 for 22-28 seconds turning on the courtesy lamps when the following conditions are met:

The exit illumination is canceled when the following conditions are met:

Theater Dimming

The BCM dims the courtesy lamps slowly from the full brightness to OFF in 3 seconds. This feature starts anytime the BCM is turning OFF the courtesy lamps.

The theater dimming does not work when the following conditions exist:

Keyless Entry Unlock Illumination

The BCM grounds circuits 156 and 157 for 36-44 seconds turning on the courtesy lamps when the following conditions are met:

Inadvertent Load (Battery Rundown) Protection

The body control module (BCM) has a feature called the inadvertent load (battery rundown) protection. The BCM de-energizes circuit 1732 10-22 minutes after the ignition switch has been turned from the ACC or RUN position to the LOCK or OFF position.

The BCM restores power to circuit 1732 when the following conditions are met:

The inadvertent battery power rundown protection feature is mileage-sensitive. The vehicles with less than 13-16.5 total driven miles have a 3 minute time-out instead of 10 minutes.

The operation of these lamps is described as part of the courtesy lamps operation. The BCM provides power (circuit 1732) and ground (circuit 157) to these lamps controlling their operation.

In addition, these lamps have switches that allow the operator to turn them ON when the courtesy lamps are OFF. The switches provide ground to these lamps turning them ON. The switches obtain ground through circuit 850. Power to these lamps is provided by the BCM through circuit 1732 in order to be protected by the inadvertent load (battery rundown) protection in case they are left in the ON position.

These lamps have switches that allow the operator to turn them ON. The switches provide ground to these lamps turning them ON. The switches obtain ground through circuit 850. The BCM does not turn ON these lamps with the rest of the courtesy lamps. Power to these lamps is provided by the BCM through circuit 1732 in order to be protected by the inadvertent load (battery rundown) protection in case they are left in the ON position.

The operation of these lamps is described as part of the courtesy lamps operation. The BCM provides power (circuit 1732) and ground (circuit 156) to these lamps controlling their operation.

The operation of the dome lamp is described as part of the courtesy lamps operation. The BCM provides power (circuit 1732) and ground (circuit 157) to the dome lamp controlling its operation.

The IP dimmer switch allows the operator to turn ON the courtesy lamps from inside the vehicle. When the IP dimmer switch is in the DOME position the switch sends a voltage signal to the BCM through circuit 1495 causing the BCM to turn ON the courtesy lamps.

When the IP dimmer switch is OFF the BCM turns OFF the courtesy lamps. The IP dimmer switch is protected by the inadvertent load (battery rundown) protection in case the IP dimmer switch is left in the DOME position with the ignition switch in the LOCK or OFF position.

The IP compartment lamp turns ON when the IP compartment is open. The IP compartment lamp has a switch that closes (providing ground to the lamp) when the IP compartment is open and the switch opens when the IP compartment is closed. The IP compartment lamp switch receives voltage through circuit 1732 and ground through circuit 1450. The IP compartment is protected by the inadvertent load (battery rundown) protection in case that the IP compartment is left open.

The console compartment lamp turns ON when the console compartment is open with the ignition switch in the RUN or ACC position. The console compartment lamp has a switch that closes, providing voltage to the lamp, when the console compartment is open. The console compartment lamp receives power through circuit 635 and ground through circuit 1450. circuit 643 is hot when the ignition switch is in the ACC or RUN position. The console compartment lamp does not turn ON when the ignition switch is in the LOCK or OFF position.

The rear compartment courtesy lamp turns ON when the rear compartment lid is open. The rear compartment lamp has a switch that closes, providing ground to the lamp (circuit 350), when the rear compartment lid is open. The rear compartment lamp receives voltage through circuit 1732 and ground through circuit 737. The rear compartment courtesy lamp is protected by the inadvertent load (battery rundown) protection in case the rear compartment lid is left in the open position.
