Restore Your Vehicle’s Electrical System with a VIN-Programmed BCM
Are you battling bizarre electrical gremlins in your 2006-2013 Chevrolet Impala or other compatible GM vehicle? Issues like flickering lights, unresponsive power windows and locks, or a persistent “Service Theft System” message are classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your car’s body electronics, and when it fails, it can cause a cascade of frustrating and confusing problems. This replacement Body Control Module, part number 25934762, is the definitive solution to get your vehicle operating correctly again.
From the Diagnostic Bay
We had a 2011 Impala come in that was driving its owner crazy. The radio would turn on and off by itself, the dome light would stay on, and occasionally, the car wouldn’t start, flashing a security light on the dash. The owner had already replaced the battery and checked the alternator. After connecting our diagnostic tool, we saw multiple communication loss codes with various modules. This pointed us directly to the central hub: the BCM. Once we installed a VIN-programmed BCM like this one, all the strange electrical issues vanished instantly. It’s a common failure point that can mimic many other problems.
Why Choose Our Programmed 2006-2013 Impala BCM?
Forget expensive dealership visits and the hassle of finding a shop with the right tools. We simplify the repair process. When you purchase this BCM, we program it with the latest GM software updates using the specific Vehicle Identification Number (VIN) you provide. This means it arrives at your door ready for installation, tailored specifically to your vehicle’s factory options. This critical programming step ensures all systems communicate correctly, saving you hundreds in programming fees and diagnostic time.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that won’t turn on or off.
- ✔ The security or anti-theft system acting up, preventing the car from starting.
- ✔ False warnings appearing on the instrument cluster (e.g., door ajar, low tire pressure).
- ✔ Intermittent failure of the radio or climate controls.
- ✔ Poor communication between onboard diagnostic tools and the vehicle.
Installation and Post-Install Procedures
While this module is designed for a straightforward installation, some vehicles may require additional steps after the BCM is connected. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light illuminates 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 recalibration may be necessary to ensure proper brake light operation and to satisfy the traction control system.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that manages many of your vehicle’s non-engine related functions. This includes power windows, locks, lights, wipers, the security system, and interior convenience features.
Is this BCM truly plug-and-play?
Because we program it to your VIN, it is as close to plug-and-play as possible. However, as noted, some vehicles may require a simple relearn procedure for the airbag or brake pedal position sensor, which may require a professional scan tool.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit VIN. We cannot ship the module until we receive this information, as the programming is essential for the part to function in your vehicle.
What happens if my airbag light is on after installation?
This indicates the BCM needs to be synced with the airbag’s Supplemental Deployment Module (SDM). A qualified technician with a high-level scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old BCM back?
No. This purchase does not require a core return. You can keep your original module.
