Plug-and-Play Solution for Your 2008-2012 Express 2500 BCM
Don’t waste time and money at the dealership. We simplify the repair process. When you purchase this module, simply provide us with your vehicle’s 17-digit VIN. Our technicians will program the BCM with the latest GM-certified software specific to your vehicle’s configuration. This ensures that when the part arrives, it’s ready for installation without the need for an expensive trip to the dealer for programming. This service is included with your purchase.
While the core programming is done, some simple, on-vehicle relearn procedures may be necessary after installation to ensure all systems communicate correctly. This can include:
- Airbag System Sync: If the airbag light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure may be needed with a pro-level scan tool.
- Brake Pedal Position Relearn: This may be required to ensure proper brake light and traction control operation.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that manages and controls your vehicle’s non-engine related functions, such as power windows, locks, lights, security system, wipers, and instrument panel warnings.
Do I need to get this BCM programmed?
No. We handle the programming for you before shipment. Just provide your vehicle’s VIN during or after checkout, and it will arrive ready to be installed with the latest software for your specific vehicle.
Is this a simple plug-and-play installation?
For the most part, yes. The main programming is done. However, depending on your exact model, you may need to perform a simple ‘relearn’ procedure for the brake pedal position sensor or airbag system, which sometimes requires a diagnostic tool.
How do I find my original BCM part number?
The part number is printed on a sticker on the case of your original BCM. The location varies, but it’s often under the dash on the driver’s side or behind the center console.
