Is your vehicle’s electrical system acting possessed?
If you’re dealing with flickering lights, malfunctioning power windows, a haywire security system, or other bizarre electronic issues, the culprit is often a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can create a cascade of frustrating and unpredictable problems. Don’t let electrical gremlins take over your car, truck, or SUV. This direct-replacement GM Body Control Module is the reliable, straightforward solution to restore full functionality and peace of mind.
From the Diagnostic Bay
We had a 2011 Chevy Impala come into the shop with a classic ‘haunted car’ scenario. The dome lights wouldn’t turn off, draining the battery overnight, and the key fob was completely unresponsive. The owner had already replaced the battery and checked fuses with no luck. After a quick diagnostic scan pointed towards a communication breakdown, we identified a faulty BCM. A replacement module, programmed to the VIN before installation, resolved all the electrical gremlins in one go. This is a common failure, and a pre-programmed module is the most efficient fix.
Common Symptoms of a Failing BCM:
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights staying on, flickering, or not turning on.
- ✔ Security system issues, including random alarm activation or key fob malfunction.
- ✔ Inaccurate gauge readings or persistent warning lights on the dash (like the airbag light).
- ✔ “Service Stability System” or similar messages appearing on the driver information center.
- ✔ A complete no-start condition due to the anti-theft system not recognizing the key.
Why Choose Our Programmed GM Body Control Module?
Getting back on the road shouldn’t be complicated. That’s why we offer a simple, effective solution. This isn’t just a part in a box; it’s a complete service. We take your vehicle’s unique Vehicle Identification Number (VIN) and program the module with the latest GM software and calibrations specific to your vehicle’s options. This critical step ensures the BCM communicates correctly with all other modules, saving you a trip to the dealership and avoiding their expensive programming fees. It arrives at your door ready for installation.
Important Post-Installation Information
While this module is programmed for a plug-and-play installation, some vehicle systems may require a recalibration or ‘relearn’ procedure after the BCM is installed. This is normal and ensures all safety and convenience features work as intended.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure correct brake light operation and to clear any traction control warnings.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.

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, such as power windows, door locks, interior/exterior lighting, security systems, and more.
How does the programming process work?
After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. We use this to load the latest GM-certified software directly onto the module, making it specific to your car’s features and options.
Is this a plug-and-play part?
Yes, because we program it to your VIN, it is designed to be as close to plug-and-play as possible. However, some vehicles may require a simple relearn procedure for systems like the airbags or brake pedal position sensor, which may require a professional scan tool.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
How do I know this fits my vehicle?
You can match the part number from your original BCM to the extensive list of compatible numbers on this page. Providing your VIN during checkout is the best way to guarantee we send you a correctly programmed and compatible part.
What happens if my airbag light comes on after installation?
This is a known possibility. It means the new BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ will need to be performed by a technician with a capable diagnostic tool.
