Restore Your Impala’s Brain and End Electrical Frustration
Are you chasing electrical gremlins in your 2006-2013 Chevy Impala? Flickering lights, a security system that has a mind of its own, power windows that won’t cooperate, or random warning lights on the dash are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your car’s body electronics, and when it starts to fail, it can cause a cascade of confusing and frustrating problems. Stop throwing parts at the issue and get the definitive solution.
This is a direct-fit replacement Body Control Module, arriving at your door fully programmed to your vehicle’s specific VIN. We load it with the latest GM-approved software, ensuring optimal performance and compatibility right out of the box. This means you can bypass the expensive trip to the dealership for programming, saving you time, money, and the headache of a tow bill. This is the same quality and reliability you’d expect from the factory, made simple for at-home or professional installation.
From the Diagnostic Bay: The Case of the Haunted Impala
I once had a 2011 Impala in my shop that was driving its owner crazy. The radio would change stations on its own, the dome light would stay on, and worst of all, the anti-theft system would randomly engage, leaving him stranded. He’d already replaced the battery and checked the alternator. After hooking up my scan tool, I saw multiple communication error codes (U-codes) pointing to a network problem. From over 20 years of experience, I knew these symptoms almost always traced back to one culprit: a failing BCM. The internal circuits and relays fail over time from heat and vibration, causing these bizarre issues. We installed a VIN-programmed BCM just like this one, and the car was back to normal in under an hour. It’s a common failure, but thankfully, it’s a straightforward fix.
Is Your Impala Showing These Telltale Signs?
A failing BCM can manifest in many ways. If you’re experiencing any of the following, it’s highly likely your BCM is the root cause:
- ✔ Erratic power windows, door locks, or interior/exterior lights.
- ✔ The security or anti-theft system activates randomly, preventing the car from starting.
- ✔ Warning lights for the ABS, Traction Control, or StabiliTrak system are illuminated.
- ✔ The radio or instrument cluster behaves strangely or shuts off intermittently.
- ✔ Communication error codes stored, such as U0100, U0140, or other U-series codes.
- ✔ False warnings like ‘Door Ajar’ or ‘Trunk Open’ when they are securely closed.
A Straightforward Guide to Your Impala BCM Installation
Replacing the BCM in your 2006-2013 Impala is a job most DIYers with basic tools can handle. For the Impala, the BCM is typically located on the left-hand (driver’s) side of the dashboard, often near the steering column or behind the lower dash panel.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait about 10 minutes to allow the systems to fully power down.
- Access the BCM: You will likely need to remove the lower dash panel beneath the steering wheel. This is usually held in by a few screws and clips.
- Locate the Module: Identify the old BCM. It’s a plastic box with several large multi-pin electrical connectors plugged into it.
- Swap the Modules: Carefully unplug all the electrical connectors. They have locking tabs that must be depressed to release them. Unbolt or unclip the old BCM from its mounting bracket and remove it.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location. Securely plug in all the electrical connectors until they click into place.
- Reconnect and Test: Reinstall the dash panel, reconnect the negative battery terminal, and start the vehicle. Test all functions like lights, locks, and windows to confirm the repair.
Post-Installation Notes
Because this module is pre-programmed, most vehicles will not require any further steps. However, in some cases, additional synchronization may be needed:
- Airbag System Sync: If the airbag light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be done with a professional scan tool to sync the systems.
- Brake Pedal Position Relearn: On some models, a brake pedal position relearn may be required to ensure proper brake light and traction control operation.
Disclaimer: Procedures can vary slightly by year and model. Always consult a factory service manual for your specific vehicle if you are unsure.

Frequently Asked Questions
Frequently Asked Questions
Do I need to program this BCM?
No. We program the module to your car’s VIN before shipping. It arrives ready for installation, saving you a trip to the dealer.
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer that manages your vehicle’s non-engine related electronic systems, such as power windows, lights, door locks, security system, and the instrument cluster.
Will this fix my ‘Service StabiliTrak’ or ‘Service Traction Control’ message?
In many cases, yes. The BCM is a key part of the traction control system. If the BCM is failing and causing communication errors, replacing it can resolve these warnings.
Is there a core charge for my old part?
No, there is no core charge. You can keep your old module, so there’s no need to worry about return shipping.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive your VIN to program the module correctly.
What tools do I need for the installation?
For most Impala models, you’ll only need basic hand tools like a socket set and a trim removal tool or a flathead screwdriver to remove the lower dash panel.
