Circuit/System Description
WARNING: This page is about a different car, the 2007 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.
Voltage for the courtesy lamps is supplied from the Interior Lights Fuse in the instrument panel I/P electrical center to the body control module (BCM). When a door is opened, a signal is applied to the door module. The door module then applies a message to the LAN communication circuit to the BCM. The BCM then applies voltage to the courtesy lamps voltage supply circuit. The courtesy lamps are composed of the following components:
- Dome lamps
- Reading lamps
- Cargo Lamps
