Restore Your Truck’s Electrical System and Drive with Confidence
Are strange electrical problems plaguing your truck or SUV? Flickering interior lights, power windows and locks that have a mind of their own, or a security system that prevents your engine from starting are all classic signs of a failing Body Control Module (BCM). Don’t let these frustrating issues compromise your vehicle’s reliability. This professionally programmed BCM is the definitive, hassle-free solution to get your truck’s essential functions working like new again.
Common Failure Symptoms & Your Direct Solution
A faulty BCM can cause a wide range of confusing and intermittent problems. If you’re experiencing any of the following, a replacement is likely needed:

Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that controls and monitors many of your vehicle’s non-engine-related electronic functions. This includes the power windows, door locks, interior and exterior lighting, alarm system, and instrument panel warnings.
Is it absolutely necessary to provide my VIN?
Yes. To ensure a plug-and-play installation, we must program the BCM with your vehicle’s unique Vehicle Identification Number (VIN). This allows the module to communicate correctly with the other computers in your truck or SUV.
How difficult is the installation process?
For most of the listed vehicles (like the S10, Blazer, and Hombre), the BCM is located behind the center or left-hand side of the dashboard. The physical replacement is straightforward for someone with basic mechanical skills. However, please be aware that post-installation procedures, such as an Airbag System Sync or Brake Pedal Position Relearn, may be necessary and require a professional scan tool.
My original part number is different. Will this still work?
Yes, this module is a direct replacement for several part numbers. Please check the fitment list on this page, which includes part numbers like 19153625, 8191536250, and 09366801. If your part number is on our list, this module will fit and function correctly in your vehicle.
What should I do if my airbag light turns on after installing the new BCM?
If the airbag warning light is on after installation, it means the new BCM needs to be synchronized with the vehicle’s airbag system (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ will need to be performed by a qualified technician using a professional-grade diagnostic tool to resolve this.
Is any other programming needed after I install this?
No, the core programming is complete. The GM BCM 16257125 arrives flashed to your VIN. The only additional steps that might be needed are the specific ‘relearn’ or ‘sync’ procedures mentioned, which are sometimes required after disconnecting the battery or replacing a major electronic module.
