Voltage to the coil of the courtesy lamp relay, dome, reading lamp, courtesy lamps, cargo Lamp, instrument panel (IP) compartment lamp and the underhood lamp is supplied from the Inadvertent power relay on CKT 1732. The inadvertent power relay receives voltage from the CTSY LP fuse which is hot at all times. Ground for the courtesy lamps goes through the courtesy lamp relay. Both relays are controlled by the body control module (BCM) based on inputs from door jamb switch, dome lamp switch or door handle switch. The BCM will supply a ground to the courtesy lamp relay when closing any one of the above switches to ground. Ground for the reading lamp, cargo lamp, IP compartment lamp and the underhood lamp is supplied by its own ground.
