Lighting Control Module

This vehicle uses a Lighting Control Module (LCM). This eliminates the electronic interference and heat associated with the thermo-electric devices used previously. The LCM is a microprocessor based module that controls several vehicle subsystems, responds to electrical input signals from various switches, sensors, and external modules and is located on the LH side of the instrument panel. LCM subsystem functions include:
- headlamps with autolamps.
- turn signal lamps/hazard flasher lamps.
- cornering lamps.
- parking lamps.
- Daytime Running Lamps (Canada only).
- courtesy lamps.
- demand lamps.
- battery saver.

The LCM interfaces with the Driver Door Module (DDM) via Standard Corporate Protocol (SCP) for illuminated entry.
