Is Your GM Truck Plagued by Electrical Gremlins?
If you’re dealing with flickering lights, unresponsive power windows, a malfunctioning security system, or strange HVAC behavior, the root cause is often a failing Body Control Module (BCM). The BCM is the central nervous system for your truck’s body electronics, and when it starts to fail, it can create a cascade of frustrating and seemingly unrelated issues. This VIN-programmed Body Control Module, compatible with part number 15943678, is the definitive solution for restoring full electrical functionality to your 2007-2013 GM truck or SUV, including the Chevrolet Silverado, GMC Sierra, Tahoe, and Yukon.

The Plug-and-Play Solution: Your Silverado 2500 Body Control Module
Don’t waste time and money at the dealership. We take the hassle out of the repair by programming this module to your vehicle’s specific VIN before it ships. This ensures that all factory-installed options and security protocols are correctly configured, making installation a simple plug-and-play process. Located under the driver’s side dash near the steering column, the physical swap typically takes less than 15 minutes. Once installed, it will seamlessly integrate with your truck’s existing electronic systems.
While the module is designed for immediate operation, some vehicles may require a simple relearn procedure. If an airbag warning light appears after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function. This re-establishes communication between the new BCM and the airbag system. In some cases, a Brake Pedal Position Relearn may also be necessary to ensure proper brake light and traction control function. This direct-fit Silverado 2500 Body Control Module is the most effective way to restore your truck’s performance and reliability.
Frequently Asked Questions
What does a Body Control Module do on a Silverado?
The BCM acts as the main computer for your truck’s comfort and convenience features. It controls power windows, locks, interior/exterior lights, wipers, the security system, and HVAC functions.
Is this BCM truly plug-and-play?
Yes, it is. We program the module to your vehicle’s VIN before shipping, so it’s ready for installation right out of the box without needing a trip to the dealer for programming.
Why is VIN programming so important?
VIN programming loads your vehicle’s specific software and security information onto the module. This ensures all features work correctly and allows the BCM to communicate properly with other computers in your truck, like the ECU and airbag module.
Where is the BCM located on a 2013 Silverado 2500?
The Body Control Module is typically located under the driver’s side dashboard, to the left of the steering column. It’s an accessible component that can be replaced with basic hand tools.
What happens if the airbag light comes on after I install it?
If the airbag light is on, it means the new BCM needs to be electronically ‘introduced’ to the airbag system (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure, which syncs the modules.
Do I need to return my old BCM?
No. There is no core charge for this part. You can keep your original module without any additional fees or hassle.
