Tired of Chasing Electrical Gremlins in Your GM Truck or Van?
Is your trusty Chevrolet, GMC, or Isuzu suddenly acting possessed? Flickering lights, intermittent power windows and locks, a security light that won’t turn off, or an engine that refuses to start can all point to a single, frustrating culprit: a failing Body Control Module. These random, unpredictable issues can make your vehicle unreliable and unsafe. Instead of spending a fortune at the dealership on diagnostics and programming fees, you can restore your vehicle’s proper function with this direct-fit, VIN-programmed BCM.
Common Symptoms of a Failing BCM & Your Solution
A faulty BCM can disrupt communication between your vehicle’s various electronic systems, leading to a wide range of problems. If you’re experiencing any of the following, our pre-programmed 16257125 BCM is the definitive solution:

An Expert’s Insight: Why Pre-Programming is Non-Negotiable
As a technician with over two decades of experience, I’ve seen countless installations go wrong because of programming issues. On these late 90s and early 2000s GM vehicles, the BCM is the central hub for everything from the power locks to the anti-theft system. Simply installing a blank or used module from another vehicle will not work—it will often create more problems than it solves. Our VIN-programming service isn’t just a convenience; it’s a critical step that ensures the BCM correctly recognizes all of your vehicle’s specific options and systems. This is the difference between a quick, successful repair and a vehicle that’s stuck in your driveway waiting for a tow to the dealer.
After Installation: What to Expect
In most cases, this 16257125 BCM is a simple plug-and-drive repair. However, depending on your specific vehicle, a couple of simple relearn procedures may be necessary. This is normal and ensures all systems are properly synced.
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag module.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician if you are unsure about any post-installation steps.
Frequently Asked Questions
How do I provide my vehicle’s VIN?
After you complete your purchase, you can add your 17-digit VIN to the order notes or send it to us in a message. We cannot program and ship your module without it, so please provide it promptly to avoid delays.
Is this BCM difficult to install?
The physical installation is generally straightforward. The module is typically located under the dashboard. The main benefit of our service is that the complex electronic programming is already done for you, making it a plug-and-play process from a software perspective.
What if my airbag light comes on after installation?
This is a known possibility. It simply means the new BCM needs to be electronically introduced to the vehicle’s airbag module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade scan tool to resolve this.
Will this 16257125 BCM fix all of my vehicle’s electrical issues?
This module will resolve any problem directly caused by a failing BCM. The symptoms we’ve listed are the most common indicators. However, proper vehicle diagnosis is always recommended, as wiring or sensor issues can sometimes mimic BCM failure.
Do I have to send my old part back?
No. We do not require you to return your original module. There is no core charge associated with this purchase, which simplifies the process for you.
Is this the correct part for my truck/van?
Please check the part number on your original BCM to ensure it matches 16257125 or one of the other compatible numbers listed. You can also check our fitment list. If you’re still unsure, feel free to contact us with your VIN, and we’ll be happy to verify compatibility.
