End Your Truck’s Electrical Gremlins for Good
Is your GM truck or SUV acting possessed? Flickering lights, intermittent wipers, power windows and locks with a mind of their own, or a security light that won’t turn off are classic signs of a failing Body Control Module (BCM). These frustrating and unpredictable issues can make your dependable vehicle feel unreliable. This isn’t just an annoyance; it’s a breakdown of your vehicle’s core comfort and security systems. Stop throwing parts at the problem and get the definitive solution with our VIN-programmed BCM.

A Technician’s Perspective
On these early 2000s GM trucks, the BCM is the traffic cop for nearly all the interior electronics. When it starts to fail, it can send confusing signals that mimic other problems, leading owners down a rabbit hole of replacing good switches and motors. The real fix is a properly functioning BCM. The most critical step, however, is the programming. An unprogrammed module is just a plastic box. By programming this 2000 Sierra 2500 BCM to your VIN before it even leaves our facility, we are completing the most crucial part of the repair for you, ensuring all systems are recognized and function as the factory intended.
Important Post-Installation Information
To ensure a smooth process, please be aware of these potential post-installation procedures. While not always required, they are a normal part of replacing a BCM in certain vehicles.
Airbag System Sync: If your 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 system.
Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct brake light and traction control operation.
We always recommend consulting a factory service manual or a qualified technician for your specific vehicle.
Frequently Asked Questions
What information do you need from me to program the BCM?
After you complete your purchase, we will need your vehicle’s 17-digit Vehicle Identification Number (VIN). This allows us to load the exact, correct software for your truck’s specific features and options.
Is this part difficult to install?
The physical installation is typically straightforward for someone with basic mechanical skills. The BCM is usually located under the driver’s side of the dashboard. The most difficult part of the job—the programming—is already done by us before we ship it to you.
Do I have to send my old BCM back?
No. This product comes with no core charge. You can keep your original part, which simplifies the process for you.
What if my airbag light turns on after I install it?
This is a known possibility. It means the new BCM needs to be electronically introduced to the vehicle’s airbag module (SDM). A repair shop with a professional-grade diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Will this 2000 Sierra 2500 BCM fit other models?
Yes, this module is compatible with a wide range of GM trucks and SUVs from that era, including the Silverado, Suburban, Tahoe, and Yukon, as long as the service number matches. Please check the fitment list on this page to confirm compatibility with your vehicle.
Is this a simple plug-and-play installation?
It is as close to plug-and-play as possible because we handle the programming. However, as noted, some vehicles may require additional relearn procedures (like for the airbag or brake sensor) with a scan tool to finalize the installation and clear any warning lights.
