BCM Basics

BCM Body Control ModuleA General Electric Module (GEM) is a computer component in an Ford automobile that checks, regulates and operates electronic devices throughout the car. Typically in a car the GEM or BCM controls the power windows, power mirrors, air conditioning, immobilizer system, central locking, etc. The GEM or BCM communicates with other on-board computers via the car’s vehicle bus, and its main application is controlling load drivers – actuating relays that in turn perform actions in the vehicle such as locking the doors or dimming the salon overhead lamp.

When electric devices first began being used in cars and trucks, each device was governed by a separate electric component. There was a module for the air-conditioning, a module for the interior lighting, a module for the door locks, and so forth. A body control module gathers all these separate modules under one system so that they function together instead of separately, a format easier to both manufacture and troubleshoot. Since the Body Control Module controls multiple things, when it fails, multiple things will not work or not work correctly.
