I/P and Rear Compartment Courtesy Lamps

Courtesy lamp operation is controlled through the CTSY LP MicroRelay #42 by the Body Control Module (BCM). Battery voltage is supplied to the relay coil and switch by circuit 1240 through the C/LADL Mini Fuse(R) #29. When the BCM receives a courtesy lamp on request the CTSY LP MicroRelay #42 control circuit 690 is grounded through the BCM energizing the relay coil. When the relay coil is energized the relay switch is drawn closed and battery voltage is supplied to the courtesy lamps through the courtesy lamp feed circuit 740. Each courtesy lamp is grounded through circuit 150 to splice pack grounds.
