Feature Customization - Roof Rail Reading Lamps

These lamps have switches that allow the operator to activate them. The switches, upon activation, provide ground to these lamps turning them to the ON position. The switches obtain ground through CKT 650. The BCM does not turn on these lamps with the rest of the interior courtesy lights. Power to the roof rail reading 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.
