This means the module is ready to communicate with your vehicle’s other systems, like the Engine Control Module and Airbag System, the moment you plug it in.

Frequently Asked Questions
What does a Body Control Module do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, door locks, the security system, interior and exterior lighting, wipers, and the HVAC (heating and air conditioning) system.
Is this part truly plug-and-play?
Yes, because we program it to your vehicle’s VIN before shipping, it is ready for installation without requiring any additional programming from a dealership for most functions. In some cases, a post-installation procedure like an ‘SDM Key Update’ may be needed with a high-level scan tool if the airbag light persists.
Will this fix my airbag light with code B1001?
A faulty BCM is a very common cause of an airbag light with DTC B1001. Replacing it with our programmed GM 25844480 Body Control Module often resolves this issue. If the light remains on after installation, you will need to perform the ‘Setup SDM Primary Key in BCM’ procedure using a compatible diagnostic tool.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your old module, which saves you the time and expense of return shipping.
How can I be sure this fits my 2013 Sierra Denali 3500?
This module fits a wide range of 2007-2013 GM trucks and SUVs. You can confirm fitment by matching your original part number to the extensive list of interchangeable numbers on this page, including 25835966. Providing your VIN during checkout ensures we program it correctly for your specific vehicle.
What tools are needed for installation?
Installation is typically straightforward, requiring only basic hand tools like a socket set or nut driver to remove the lower dash panel. The BCM is usually located under the driver’s side dashboard near the steering column and is held in by simple clips or small bolts.
