Are you battling frustrating electrical gremlins in your GM truck or van? Issues like flickering lights, malfunctioning power windows, or a security system that has a mind of its own are often signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide array of confusing and intermittent problems. This VIN-programmed BCM is the definitive solution to restore your vehicle’s functionality and peace of mind.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We flash the module with the latest official GM software updates, specifically programmed to your vehicle’s unique VIN. This critical step ensures seamless communication between the BCM and your vehicle’s other electronic systems, eliminating the need for an expensive trip to the dealership for programming. Simply provide your VIN after purchase, and we’ll handle the rest, shipping you a part that’s ready for installation right out of the box.

Installation and Post-Install Notes
Physical installation is straightforward, typically involving removing a few trim panels under or in the center of the dashboard to access the old module. However, please be aware of potential post-installation procedures:
- 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 system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be required to ensure correct brake light and traction control operation.
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 the BCM do?
The Body Control Module (BCM) acts as the brain for your vehicle’s electronic accessories. It controls functions not related to the engine, such as power windows, locks, lights, wipers, the security system, and the instrument cluster.
Do I need to send my old part back?
No. This purchase comes with no core charge. You can keep your original module.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information.
Is this part difficult to install?
The physical replacement is typically simple for someone with basic mechanical skills, as the BCM is usually located under the dash. However, be prepared for potential post-installation electronic procedures, which may require a professional-grade scan tool.
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 synced with your vehicle’s airbag module (SDM). A repair shop with a capable diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Will this fix my specific electrical problem?
This BCM will fix problems directly caused by a faulty module. While the symptoms listed are very common indicators of BCM failure, we always recommend a proper diagnosis by a qualified technician to rule out other potential causes like wiring or switch issues.
