Is body control module same as ECU?
In the automotive electronics industry, Control Unit ECU is used as a generic term for any built-in system that controls multiple electrical features in a car. It usually includes: Body Control Module (BCM) ... Engine control unit /Engine Control Module (ECM and PCM)
What is a body control module fuse?
The 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, flashing the turn signals (in older cars), or dimming the interior lighting. ...
Can disconnecting battery reset BCM?

Does the BCM control the fuel pump?
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. For example: the status of the doors, interior lights, trunk status, etc. and in some cases can even control the fuel pump.
Does the body control module have to be programmed?
Most BCMs need to be programmed by the remanufacturer or a shop equipped with the proper tools. If the replacement BCM needs programming, it must be programmed with the latest operating software and vehicle calibrations.
What does a body control module control?
