Tired of Unpredictable Electrical Problems in Your GM Truck or SUV?
Is your Silverado, Sierra, or Tahoe suffering from strange electrical issues? One moment the air conditioning works, the next it doesn’t. Your power windows have a mind of their own, and a persistent airbag light is staring you down. These aren’t just annoyances; they’re signs of a failing Body Control Module (BCM).

Expert Insight: The Power of Pre-Programming
As a technician, I’ve seen countless vehicle owners spend hundreds of dollars at a dealership just for programming after installing a new module. Our process eliminates that entire step. By flashing the programmed 25844480 BCM with your VIN before it ships, we ensure it’s ready to communicate with your vehicle’s Powertrain Control Module (PCM) and other systems right out of the box. This not only saves you money but also significant time and hassle, turning a potentially complex repair into a simple, straightforward job you can do in your own driveway.
Frequently Asked Questions
What exactly does a Body Control Module do?
The BCM acts as the central computer for your vehicle’s non-engine related functions. It manages power windows, door locks, the security system, interior and exterior lights, climate controls, and wipers. When it fails, these systems can become erratic.
Why is VIN programming so important?
VIN programming loads your vehicle’s specific software and security information onto the BCM. Without it, the module won’t be able to communicate correctly with other computers in your vehicle, leading to system malfunctions or the vehicle not starting at all. Our pre-programming makes it a true plug-and-play part.
What if my airbag light is on after installation?
If the airbag warning light persists (often with code B1001), it means the BCM needs to be synced with the Sensing and Diagnostic Module (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a simple sync, not a full reprogramming.
How difficult is the installation process?
The BCM is typically located under the steering column or dashboard and is held in by a few clips or bolts. For most DIYers with basic tools, the physical replacement takes less than 15 minutes. Our pre-programming handles the complicated part for you.
Is there a core charge for my old part?
No, there is no core charge required for this module. You can keep your old part without any hassle or need to return it, simplifying the repair process.
How do I know if this programmed 25844480 BCM will fit my vehicle?
This module fits a wide range of 2007-2013 GM trucks and SUVs, including the Silverado, Sierra, Tahoe, Yukon, Suburban, and Escalade. Please refer to the detailed fitment list on this page or provide us with your VIN to confirm perfect compatibility.
