Courtesy/Illuminated Entry Lamps

These lamps may be manually turned on by placing the interior lamp switch in the ON position, or by opening a door.

• The Dome Lamp
• The Rear Compartment Courtesy Lamp
• The Rear View Mirror Map Lights

The inadvertent power control circuit of the BCM supplies battery positive voltage to the dome lamp and the map lamps. When any door is opened, the door jamb switch contacts close providing a door open input to the BCM. The BCM then provides a ground to the interior lamps. The interior lamps receive a ground at G401 or G403.

If the driver inadvertently leaves any interior lamp on the BCM will turn it off after a 20 minute time-out.

The courtesy lamps will normally turn off using the theater dimming feature. The BCM provides a pulse width modulated ground to the interior lamps for the theater dimming feature. The courtesy lamps will also turn off immediately if a door lock command is received with all the doors closed, or if the ignition switch is turned to the ON position.
