PRINCIPLES OF OPERATION
The lighting control module (LCM) is a microprocessor-based module that controls several vehicle subsystems. The LCM responds to electrical input signals from various switches, sensors, and external modules. The LCM is located under the LH side of the instrument panel. Subsystem functions of the LCM include headlamps with autolamps, turn signal lamps/hazard flasher lamps, cornering lamps, parking lamps, daytime running lamps (DRL), courtesy lamps, demand lamps, battery saver and control backlighting. The LCM interfaces with the driver door module (DDM) through the standard corporate protocol (SCP) communication network for the illuminated entry feature.
