Is Your Chevrolet Impala Experiencing Strange Electrical Problems?
If your 2006-2013 Impala is plagued by flickering lights, malfunctioning power windows or locks, a faulty security system, or other bizarre electrical issues, a failing Body Control Module (BCM) is the likely culprit. The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a wide range of frustrating and seemingly unrelated problems. This can make your vehicle unreliable and difficult to operate. Don’t let electrical gremlins take over your car. Restore its functionality and your peace of mind with our reliable, VIN-programmed replacement BCM.
From the Diagnostic Bay
We had a 2011 Impala come into the shop with a list of complaints that seemed endless. The dome lights wouldn’t turn off, the driver’s side power window worked intermittently, and the remote key fob was useless. The owner had already replaced the battery and checked fuses with no luck. After connecting our diagnostic tool, we saw multiple communication errors pointing towards the BCM. Instead of a dozen small problems, it was one big one. We installed a VIN-programmed Impala Body Control Module, and like magic, every single issue was resolved. It’s a perfect example of how this single component can be the root cause of widespread electrical chaos.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, and mirrors.
- ✔ Erratic behavior from interior or exterior lights (staying on or not turning on).
- ✔ Malfunctioning dashboard gauges or warning lights (like the security light).
- ✔ Remote keyless entry (fob) not working correctly.
- ✔ The vehicle’s anti-theft system preventing the car from starting.
- ✔ Unresponsive climate control functions.
Why Choose Our Programmed Impala Body Control Module?
Getting your vehicle back to normal shouldn’t be a hassle. We make the process simple. This isn’t just a part in a box; it’s a complete solution. We pre-program the module to your vehicle’s specific VIN, loading it with the latest software updates from GM. This ensures compatibility and proper function right out of the box, saving you a trip to the dealership and expensive programming fees. Simply provide your VIN after purchase, and we’ll handle the rest.
Installation and Post-Install Steps
While this module is designed for a straightforward installation, some vehicles may require additional steps to ensure all systems communicate correctly after the new BCM is installed. These are known as ‘relearn’ or ‘synchronization’ procedures.
- 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 recalibration may be necessary to ensure brake lights and traction control operate as intended.
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 do?
The BCM acts as the brain for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, the security system, and more.
Is this BCM truly plug-and-play?
Because we program it to your VIN, it is as close to plug-and-play as possible. In most cases, it will work immediately. However, as noted, some vehicles may require simple relearn procedures for systems like the airbags or brake pedal sensor.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information for programming.
What if my original part number isn’t on your list?
Please contact us with your vehicle’s VIN and original part number before ordering. We can verify compatibility to ensure you receive the correct part for your vehicle.
Is there a core charge for my old part?
No, there is no core charge. You can keep your original module.
