Are you battling frustrating electrical gremlins in your GM truck or SUV? A faulty Body Control Module, or BCM, is often the culprit behind a host of perplexing issues. The BCM acts as the central command center for your vehicle’s body electronics, controlling everything from your power windows and locks to the interior lights and security system. When it begins to fail, it can make your vehicle feel unreliable and unpredictable. This replacement BCM, part number 15081796, is the definitive solution to restore your vehicle’s proper function.

We flash it with the latest, most stable software updates from GM, ensuring optimal performance and compatibility right out of the box. This is a true plug-and-play solution designed for the DIY mechanic and professional technician alike.

Post-Installation Procedures
While this module is designed for a straightforward installation, some vehicles may require additional steps to ensure all systems communicate correctly. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation 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 does a Body Control Module (BCM) do?
The BCM is a computer that manages and controls the various electronic accessories in your vehicle’s body, such as the lights, windows, locks, wipers, security system, and more. It’s the brain behind your car’s comfort and convenience features.
Is this part difficult to install?
For most compatible models like the 2002 Yukon, the BCM is located under the steering column and is accessible by removing a lower dash panel. It is held in by a few bolts or clips and has several electrical connectors. Because this unit comes pre-programmed, the physical installation is a direct swap.
How do I provide my VIN for programming?
After you complete your purchase, you can add your 17-digit VIN to the order notes or simply reply to your order confirmation email with it. We cannot ship your part until we have your VIN to perform the programming service.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
What if my airbag light is on after I install this BCM?
This is a known possibility. It means the new BCM needs to be electronically introduced to your vehicle’s airbag system (SDM). A mechanic with a bi-directional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve the light.
Will this BCM fit other vehicles besides the 2002 Yukon?
Yes, this module fits a wide range of 2002-2005 GM trucks, vans, and SUVs, including the Silverado, Sierra, Tahoe, Suburban, Astro, Safari, and Blazer/S10. Please refer to the detailed fitment list on this page and match your original part number to ensure compatibility.
