Are you experiencing strange and frustrating electrical issues with your GM truck or van? A faulty Body Control Module (BCM) is often the culprit. The BCM acts as the central nervous system for your vehicle’s body electronics, managing everything from your power windows and locks to your interior lights and security system. When it fails, it can cause a cascade of problems that are difficult to diagnose. This replacement BCM, part number 15116065, is the definitive solution for restoring your vehicle’s full functionality.
This isn’t just a part; it’s a complete, ready-to-install solution. We pre-program each module to your vehicle’s specific VIN before shipping. This critical step ensures seamless integration with your existing 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, sending you a BCM with the latest GM software updates already installed.

Post-Installation Information
While our programming makes this a plug-and-play part for most vehicles, some models may require minor post-installation procedures. If your airbag warning light illuminates after installation, a technician will need to perform an ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool. Additionally, some vehicles may require a ‘Brake Pedal Position Relearn’ to ensure proper brake light and traction control operation. These procedures are not always necessary but are important to be aware of. Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors various electronic accessories not related to the engine, such as power windows, locks, lights, wipers, and the security system.
Is this BCM difficult to install?
Installation is generally straightforward. In most trucks, it’s located under the steering column, and in vans, it’s in the center of the dash. Since we pre-program it to your VIN, no dealer programming is required, making it a plug-and-play process. Basic hand tools are typically all that’s needed.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module without any additional cost or hassle.
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, as it is essential for programming the module correctly.
What happens if my airbag light is on after installation?
In some cases, the new BCM needs to be synced with the airbag system (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by a repair shop with a professional-grade diagnostic tool.
