Your Plug-and-Play Sierra 2500 Body Control Module Solution
The BCM is the central command center for your truck’s body electronics. It manages everything from the dome light when you open the door to the complex logic of the anti-theft system. When it fails, it can cause a cascade of confusing and seemingly unrelated symptoms. Our module is meticulously prepared with the latest GM software updates based on your VIN, guaranteeing seamless integration with your truck’s existing systems, including the Powertrain Control Module (PCM) and Sensing and Diagnostic Module (SDM).
Symptoms of a Failing BCM
- ✔ Unresponsive or malfunctioning power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ HVAC and climate control systems operating erratically or not at all.
- ✔ An active security system light or a vehicle that won’t start.
- ✔ An illuminated airbag warning light, often with DTC B1001.
- ✔ False warnings on the driver information center (DIC).
Replacing your failing part with our reliable Sierra 2500 Body Control Module is the most effective way to resolve these issues permanently. Installation is simple for any DIYer or professional technician. The module is located under the driver’s side dashboard and can be swapped in minutes. While the unit is plug-and-play, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure using a professional scan tool if the airbag light persists after installation. This syncs the new BCM with the airbag system. Additionally, a Brake Pedal Position Relearn may be needed on certain models. Best of all, there is no core charge, so you can keep your old part without any hassle.

Frequently Asked Questions
What does a Body Control Module do on my GMC Sierra?
The BCM acts as the central computer for your truck’s non-engine related electronics. It controls features like power windows, locks, interior/exterior lighting, the security system, wipers, and HVAC functions.
Is this BCM ready to install out of the box?
Yes! We pre-program the module to your vehicle’s VIN before shipping. This ensures it works with your truck’s specific features and avoids the need for a trip to the dealership for programming.
What if my airbag light is on after installation?
If the airbag light is on, it means the new BCM needs to be electronically introduced to the airbag system (SDM). This is done with a ‘Setup SDM Primary Key in BCM’ procedure, which requires a professional-grade diagnostic scan tool.
Do I need to return my old BCM?
No, there is no core charge or need to return your original part. You can keep it or dispose of it at your convenience.
How do I know this part will fit my truck?
This module fits a wide range of 2007-2013 GM trucks and SUVs. Please verify your vehicle in the fitment list and ensure your original part number is listed in our interchange list, or provide your VIN at checkout for guaranteed compatibility.
