Power and Ground 

• The primary power feed for switched/convenience lighting is supplied by a 7.5A PWM high side driver located in the BCM.
• The primary feed for the front door puddle lamps is supplied by its dedicated door module. Whereas, the rear puddle lamps are fed directly by BCM.

Switched Convenience Lighting Operation 

• The BCM provides a battery saver (load shedding) feature for the reading lamp circuit as well as the courtesy lamp circuit, which will automatically turn these lamps OFF if they are left ON for more than about 10 minutes after the electronic ignition status  message transitions to OFF. If any reading lamp input is received subsequent to a 10 minute load shed and prior to a new ignition cycle, the courtesy lamps will turn OFF after 90 seconds.
