What does the body control module control?
The automotive central body control module (BCM) is a processor-based power distribution center that supervises and controls functions related to the car body such as lights, windows, security, door locks and access control, and various comfort controls. The BCM does not control any engine-related functions.
What problems can a bad BCM cause?
A malfunctioning BCM will activate dashboard instrumentation cluster error and warning lights. These lights may flash off and on if the BCM is not able to read the sensors correctly. Your vehicle performance may also be affected as the BCM communicates with other control modules in the vehicle.
How do I know if my BCM is bad?
Common Trouble Signs
Examples include flashing dash lights, a stereo system switching from AM to CD in the middle of a broadcast, the horn honking when you put down a specific window or hazard lights activating themselves in the middle of a drive.
Will disconnecting battery reset BCM?

Can BCM keep car from starting?
In a short answer: Yes, the BCM can prevent a car from starting, and doubly so when you introduce a security/antitheft system like Passlock. The reason is that the BCM feeds inputs into the Passlock (or other security system) for it to ‘determine’ if it is being stolen or hotwired.
Can a bad BCM drain the battery?
A short circuit or faulty circuit board in the body control unit can drain the vehicle battery. A fault with the body control module can leave electrical components turned on when they should be turned off. This can drain the battery when the engine is turned off or if the vehicle is left parked overnight.
