Expert Insight: The Power of Proper Programming
From our 20+ years of experience, we know that improper programming is the number one reason for a failed BCM replacement. A generic, non-programmed module simply won’t communicate correctly with your vehicle’s other computers, like the Engine Control Module (ECM) or Supplemental Deployment Module (SDM).

Our VIN-specific programming service ensures this 2013 GMC Sierra 3500 Body Control Module is loaded with the latest GM software updates for your exact vehicle, guaranteeing seamless integration and performance right out of the box. You’re not just buying a part; you’re buying a complete, ready-to-install solution.

Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We pre-program this module to your vehicle’s VIN before it ships. This allows for a simple plug-and-play installation without the need for any additional dealership programming, saving you time and money.
Where is the Body Control Module located on my truck?
On most 2007-2013 GM trucks and SUVs, the BCM is located under the driver’s side dashboard, typically to the left of the steering column. Installation usually takes less than 15 minutes with basic hand tools.
My airbag light is on. Will this fix it?
This module can resolve airbag light issues caused by BCM failure (like DTC B1001). However, after installation, some vehicles may require an ‘SDM Key Update’ or ‘Brake Pedal Position Relearn’ procedure using a professional scan tool to sync the systems and turn off the light. This is a simple procedure for any qualified technician.
Is this the correct part for my vehicle?
This BCM fits a wide range of 2007-2013 GM vehicles, including the Silverado, Sierra, Tahoe, and Suburban. It is a direct replacement for numerous part numbers, including 25844480, 15943678, and 25835966. Please verify the part number from your original module or use our vehicle fitment tool to ensure compatibility.
What is a core charge?
A core charge is a deposit that is returned to you when you send back your old part. We do not require a core charge for this BCM, so you can keep your original module without any extra hassle.
