Tired of Your Truck’s Mind of Its Own?
Are you dealing with flickering lights, a climate control system that won’t cooperate, or power windows and locks that work only when they feel like it? These frustrating and unpredictable electrical gremlins in your Chevrolet, GMC, or Cadillac truck or SUV often point to one culprit: a failing Body Control Module (BCM). Instead of costly diagnostic guesswork and an expensive trip to the dealership, take control with this direct-fit, professionally programmed BCM and restore your vehicle’s reliability and function.
Common Symptoms & Your Solution

- Power windows, door locks, or exterior/interior lights acting erratically or not working at all.
- An airbag warning light on the dash, often with Diagnostic Trouble Code (DTC) B1001.
- Security system malfunctions, causing no-start conditions, stalling, or misfires.
- A cluster of seemingly unrelated electrical issues and DTCs that are difficult to diagnose.

An Expert’s Insight: The Power of Pre-Programming
“On these GM GMT900 platform vehicles (like the Silverado, Tahoe, and Yukon), the BCM is the traffic cop for the vehicle’s network. It has to communicate perfectly with the Engine Control Module (ECM), the security system (immobilizer), and even the airbag system (SDM). Simply swapping a BCM from another vehicle won’t work—it will cause a no-start condition or a cascade of warning lights. Our VIN programming service writes your vehicle’s unique identity into the module *before* it gets to you. This ensures all the computers on board recognize each other instantly, making the installation as simple as swapping the part. It’s the key to avoiding a tow to the dealer and getting the job done right in your own driveway.”
By installing a properly configured VIN programmed 25844480 BCM, you’re not just replacing a part; you’re restoring the core stability of your vehicle’s electronics. Get back the dependable truck or SUV you rely on every day.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer in your vehicle that manages and controls a wide variety of electronic accessories not related to the engine. This includes power windows, locks, seats, mirrors, interior and exterior lighting, the security system, wipers, and the HVAC (heating and air conditioning) system.
Why is VIN programming so important for this part?
VIN programming loads your vehicle’s specific software and security information onto the BCM. Without it, the BCM won’t be able to communicate correctly with other modules in your vehicle, which can lead to features not working or even prevent the vehicle from starting. Our service handles this for you, so it’s ready to install out of the box.
Is this installation difficult to do myself?
For most DIYers with basic tools, the physical installation is straightforward. The BCM is typically located under the driver’s side dashboard near the steering column. The process usually takes less than 30 minutes. The key is that our pre-programming eliminates the most difficult part: the computer setup.
What if the airbag light is still on after I install it?
In some cases, especially if DTC B1001 was present, an additional “Setup SDM Primary Key in BCM” procedure is required. This is a simple reset that must be done with a professional-grade scan tool. It re-syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
Do I need to return my old BCM?
No. There is no core charge for this part. You can keep your old module without any hassle or extra fees.
How do I know if this is the right BCM for my truck?
This VIN programmed 25844480 BCM fits a wide range of 2007-2013 GM trucks and SUVs. The best way to confirm is to match your original part number to one of the many interchangeable numbers listed in our compatibility details. When you order, we will use your VIN to ensure perfect compatibility.
