Body Control Modules (BCMs) always control numerous vehicle functions. Which functions are bundled together in any given module depends on the respective vehicle architecture and on the partitioning of the various functions.
Tied into the electronics architecture of the vehicle as a whole, the BCMs reduce the number of plug-in connections and cable harnesses required, while at the same time offering maximum reliability and economy.
Installed in the engine compartment, BCMs control, for example, headlights, turn indicators and the windshield washer system. In the trunk they are responsible for the rear lighting system, the rear window wiper and the door lock assist.
Central BCMs bundle together the control of the locking system, the Immobilizer, the Climate Control Module and the Tire Pressure Monitoring System.
