Restore Your Impala’s Electrical Systems with a Reliable BCM
If you’re dealing with a 2006-2013 Chevrolet Impala that seems to have a mind of its own, the Body Control Module (BCM) is often the culprit. As the central command for your car’s body electronics, a failing BCM can cause a cascade of frustrating and seemingly unrelated issues. From flickering lights and malfunctioning power windows to security system errors and no-start conditions, the symptoms can be baffling. This isn’t just an inconvenience; it can be a serious safety concern.
This replacement Body Control Module is the definitive solution. We take the guesswork and hassle out of the repair by programming the unit specifically for your vehicle using your VIN. This means it arrives at your door ready for installation, loaded with the latest GM software updates to ensure optimal performance and reliability. You get a direct-fit part that restores function without the exorbitant cost and scheduling headaches of a dealership visit.
A Technician’s Notebook: The Ghost in the Machine
I’ll never forget a 2011 Impala that was towed to my shop. The owner was at his wit’s end. The radio would turn on by itself, the interior lights would stay on, and sometimes the car just wouldn’t start. He’d already replaced the battery and checked all the fuses. After connecting my scan tool, I saw a storm of communication error codes (U-codes) pointing to the BCM. These modules are notorious for internal circuit board failures, leading to precisely this kind of electrical chaos. Swapping in a VIN-programmed 2006-2013 Impala BCM had the car behaving perfectly in under an hour. It’s a common failure, but one with a straightforward fix.
Is Your Impala Showing These Symptoms?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your Body Control Module needs attention:
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ The security system acting up, causing alarm issues or preventing the car from starting (often showing a security light on the dash).
- ✔ Dashboard warning lights appearing randomly (e.g., ABS, Traction Control, Airbag).
- ✔ Intermittent no-start or no-crank conditions.
- ✔ Communication error codes stored, such as U0100, U0140, or other U-series codes.
- ✔ Radio or climate control systems behaving unpredictably.
A Straightforward Guide to Your BCM Installation
For the confident DIYer or professional mechanic, replacing the BCM in a 2006-2013 Impala is a manageable job. The module is typically located on the left (driver’s) side of the dashboard.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Access the BCM: You will likely need to remove the lower dash panel beneath the steering column to gain access. It’s usually held in by a few screws or clips.
- Locate the Module: Identify the old BCM. It’s a black plastic box with several large electrical connectors plugged into it.
- Disconnect and Remove: Carefully unplug all electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location. Securely plug in all the electrical connectors, ensuring they click into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—windows, locks, lights, radio, etc.—to confirm the repair.
Important Post-Installation Notes
While our programming handles the majority of the setup, some vehicles may require a couple of quick relearn procedures. This is normal. Specifically, a Brake Pedal Position Relearn might be needed for proper brake light and traction control operation. In some cases, if the airbag light is on, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. As always, consulting a factory service manual for your specific model is the best practice.

Frequently Asked Questions
Frequently Asked Questions
Do I need to do any programming myself?
No. We program the BCM to your vehicle’s VIN before shipping. It arrives ready to be installed. Some minor relearn procedures, like for the brake pedal position sensor, may be required after installation, which is a normal part of the process for many vehicles.
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship the module until we have this information to program it correctly.
Is there a core charge for my old BCM?
No, there is no core charge. You can keep your original module, so there’s no need to worry about the cost or hassle of sending a part back.
What tools are needed for installation?
Basic hand tools are usually sufficient, such as a socket set and a trim removal tool to safely take off the dash panel. No special programming tools are required on your end.
What happens if my airbag light comes on after installation?
This is uncommon but can happen. It means the new BCM needs to be synced with the airbag’s Sensing and Diagnostic Module (SDM). This requires a professional-grade scan tool to perform the ‘Setup SDM Primary Key in BCM’ function. A local repair shop can typically perform this service.
