Lighting Control Module (LCM)
WARNING: This page is about a different car, the 2005 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.
The LCM eliminates the electronic interference and heat associated with the thermoelectric devices used previously. The LCM is a microprocessor based module that controls several vehicle subsystems. It responds to electrical input signals from various switches, sensors, and external modules.
LCM exterior lighting subsystem functions include:
- Headlamps with autolamps
- Turn signal lamps/hazard flasher lamps
- Parking lamps
- Battery saver
The LCM also has a feature that turns on the exterior lamps when the windshield wipers are turned on. For additional information, Refer to WIPERS AND WASHERS .
