Is Your GM Vehicle Plagued by Electrical Gremlins?
If you’re dealing with flickering lights, malfunctioning power windows, or strange warning messages, a failing Body Control Module (BCM) is likely the culprit. The BCM acts as the central command center for your vehicle’s body electronics, managing everything from the interior lights and power locks to the security system. When it fails, it can cause a wide range of confusing and frustrating issues that can be difficult to diagnose.
This replacement Body Control Module is the definitive solution for your 2006-2013 Chevrolet Impala and a vast array of other GM vehicles. Forget the hassle and expense of a dealership visit. We provide a fully programmed module, flashed with the latest GM software updates specific to your vehicle’s VIN. This ensures a seamless installation process, getting you back on the road with confidence.
From the Diagnostic Bay
We had a 2011 Impala in the shop with a classic “mystery battery drain.” The owner had already replaced the battery and alternator, but the car would still be dead every few mornings. After hours of tracing circuits, we found the BCM was intermittently failing to put the interior lighting circuit to sleep after the car was shut off. It was a tiny, invisible power draw that was enough to drain the battery over 8-10 hours. Swapping in a VIN-programmed BCM like this one solved the problem instantly. It’s often these hidden electronic faults that cause the biggest headaches.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ The security or anti-theft system light is illuminated, or the car won’t start.
- ✔ Unexplained battery drain that leaves you with a dead battery.
- ✔ Wipers or horn activating randomly or not responding to input.
- ✔ Inaccurate gauge readings or warning lights on the instrument cluster.

Post-Installation Procedures
While this module is designed for straightforward installation, some vehicles may require additional steps to sync with other onboard systems. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.
Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors various electronic accessories, such as power windows, locks, lights, wipers, and the security system. It’s the brain for your car’s body electronics.
Is this BCM difficult to install?
The physical installation is typically straightforward, involving unplugging the old module and plugging in the new one. However, some vehicles may require additional relearn procedures for systems like the airbags or brakes, which may need a professional scan tool.
How do I provide my VIN for programming?
After you complete your purchase, we will contact you for your vehicle’s 17-digit VIN. Our technicians use this to program the BCM with the correct software and settings for your exact vehicle before we ship it.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
What if my airbag light is on after installation?
This indicates that the new BCM needs to be synchronized with the airbag’s Supplemental Inflatable Restraint (SIR) system. A procedure called ‘Setup SDM Primary Key in BCM’ will need to be performed by a qualified mechanic with a compatible diagnostic tool.
Will this fit vehicles other than the Chevy Impala?
Yes. This BCM is compatible with a very wide range of GM vehicles, including models from Chevrolet, GMC, Cadillac, Buick, Saturn, and Pontiac. Please review the detailed fitment list on this page to confirm compatibility with your specific make, model, and year.
