Feature Customization - Windshield Header Courtesy/Reading Lamps

The operation of these lamps is described as part of the interior courtesy lights operation. The BCM provides power (CKT 328) and ground (CKT 690) to these lamps, controlling their operation.

In addition, these lamps have switches that allow the operator to turn them on when the interior courtesy lights are off. The switches, upon activation, provide ground to these lamps turning them to the ON position. The switches obtain ground through CKT 650. Power to these lamps is provided by the BCM through CKT 328, so that they are protected by the inadvertent load (battery rundown) protection in case they are left in the ON position.
