Tired of Unpredictable Electrical Gremlins in Your GM Truck or SUV?
Are you dealing with flickering dashboard lights, power windows with a mind of their own, or a security system that randomly acts up? These frustrating and unpredictable issues often point to a single culprit: a failing Body Control Module (BCM).

This replacement Body Control Module is the definitive solution to restore order and get your vehicle back to 100% functionality.

Expert Insight: The Importance of VIN Programming
From over 20 years of hands-on diagnostics, I can tell you that on these early 2000s GM vehicles, the BCM is not a simple swap. It’s tied into the vehicle’s security system (Passlock/VATS), options packages, and other modules. Simply installing a used or non-programmed BCM will often result in a no-start condition or a cascade of new error codes. Our VIN programming service is what makes this a viable repair for the DIYer or independent shop. We take the complexity and guesswork out of the equation, delivering a component that’s truly ready for your specific 2002 GMC Sierra 2500 BCM 15095334 application, saving you hundreds in dealer fees and diagnostic time.
Post-Installation Requirements
While this module is programmed for your vehicle, some models may require simple relearn procedures after installation to sync with other onboard systems. These are standard procedures that can be performed with a capable diagnostic scan tool.
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the systems.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor may be required to ensure proper brake light and traction control function.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What exactly does a Body Control Module do?
The BCM acts as the brain for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, interior and exterior lighting, wipers, security systems, and more. When it fails, you get the strange electrical issues this part is designed to fix.
Is programming really included in the price?
Yes, it is. After your purchase, you will need to provide us with your vehicle’s 17-digit VIN. We then program the module with the correct software and vehicle-specific options before shipping it to you. This saves you a costly trip to the dealership.
Will I need to do anything after I install it?
In many cases, the module will work immediately. However, depending on your specific model, you may need a qualified technician with a professional scan tool to perform a couple of quick relearn procedures, such as an Airbag System Sync or a Brake Pedal Position Relearn, to ensure all systems communicate correctly.
How can I be sure this fits my vehicle?
The best way is to match the part number from your original BCM to one of the numbers listed (15063578, 15081796, 15095334, 19208537). You can also use the detailed compatibility list on this page. If you’re still unsure, please contact us with your VIN before ordering.
What if my original part number isn’t on the list?
If your part number is not listed, this module may not be the correct one for your vehicle. GM used many different BCMs with specific hardware and software. We recommend finding a module that explicitly lists your original part number to ensure compatibility.
