Is Your Chevrolet Impala Experiencing Strange Electrical Issues?
If you’re dealing with a frustrating array of electrical gremlins in your 2006-2013 Chevrolet Impala—such as power windows that won’t cooperate, door locks with a mind of their own, intermittent security system alerts, or interior lights that stay on—the culprit is often a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it malfunctions, it can cause widespread and confusing problems. Don’t let a faulty module compromise your car’s functionality and your peace of mind. This is your direct, reliable solution.
From the Diagnostic Bay
We had a 2011 Impala come into the shop with a complaint that was driving the owner crazy: the interior dome lights would randomly turn on while driving and sometimes refuse to turn off after parking, draining the battery overnight. We checked all the door jamb switches and wiring, finding nothing obvious. After hooking up the scan tool, we saw erratic data coming from the BCM related to door status signals. We swapped in a new, correctly programmed BCM, and the problem vanished instantly. It’s a classic example of how a single failing module can create bizarre, seemingly unrelated symptoms.
Diagnosing a Failing 2006-2013 Impala BCM
A failing BCM can manifest in numerous ways, often making diagnosis tricky. If your vehicle is exhibiting several of the following symptoms, it’s highly likely that your Body Control Module needs replacement. This module is the key to restoring proper function and eliminating those persistent electrical headaches.
Common Symptoms of a Faulty BCM
- ✔ Power windows or door locks operating intermittently or not at all.
- ✔ The security system or anti-theft light flashing, potentially causing a no-start condition.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) staying on or not turning on.
- ✔ The dashboard displaying incorrect information or warning lights appearing without cause.
- ✔ Key fob functions becoming unreliable or ceasing to work.
- ✔ Wipers, horn, or radio behaving erratically.
- ✔ False ‘Door Ajar’ warnings on the instrument cluster.
The Plug-and-Play Solution Your Vehicle Needs
Forget the hassle and expense of a dealership visit. We provide a straightforward solution by programming this Body Control Module specifically for your vehicle before it ships. Simply provide us with your vehicle’s VIN (Vehicle Identification Number) after purchase, and our technicians will flash the module with the latest, most stable software updates directly from GM. This ensures that the BCM integrates seamlessly with your car’s existing systems, making installation as simple as possible. This is not a generic, one-size-fits-all part; it is prepared for your exact vehicle configuration.
Installation and Post-Installation Requirements
Physical installation is typically straightforward. First, disconnect the vehicle’s battery. The BCM on a 2006-2013 Impala is located on the driver’s side, to the left of the dash. Carefully unplug the electrical connectors, remove the old module, and install the new one in its place. Reconnect the connectors and the battery.
While our programming handles the majority of the setup, some vehicles may require additional steps after installation to ensure all systems communicate correctly:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool to synchronize the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn may be needed to ensure the brake lights and traction control system function correctly. This procedure also typically requires a diagnostic tool.
Disclaimer: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We handle all the programming for you before we ship the part. Just provide your vehicle’s VIN during or after checkout, and it will arrive ready for installation, flashed with the latest GM software for your specific vehicle.
Where is the BCM located on a 2006-2013 Impala?
The Body Control Module on these Impala models is typically found on the driver’s side of the vehicle, located under the dashboard to the left of the steering column.
Is there a core charge for this part?
No, there is no core charge. You can keep your old, original module without needing to send it back to us.
What should I do if my airbag light turns on after installing the new BCM?
An illuminated airbag light after installation indicates that the new BCM needs to be electronically synchronized with your vehicle’s airbag system (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which must be performed by a repair shop with a professional-grade diagnostic tool.
Will this fix my key fob not working?
In many cases, yes. The BCM is responsible for receiving signals from your key fob to operate the remote keyless entry system. If the BCM has failed, replacing it with this programmed unit should restore key fob functionality. You may need to perform a simple key fob relearn procedure, which can often be done without special tools.
