Restore Order to Your Vehicle’s Electronics
Are you battling bizarre electrical issues in your 2006-2013 Chevrolet Impala? Flickering interior lights, a security system that randomly immobilizes the car, or power windows with a mind of their own are classic signs of a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can cause widespread, frustrating problems. This isn’t just an inconvenience; it can affect vehicle security and safety systems. I’ve seen it countless times in my 20+ years of diagnostics—what seems like multiple unrelated failures often points directly to this single component.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and dealership hassle out of the equation. By providing us with your vehicle’s VIN at checkout, you will receive an Impala Body Control Module that is professionally programmed with the latest GM software specific to your car. This VIN-matching service ensures that all the original features and options your car came with will function correctly right out of the box. We also offer a cloning service, where we transfer the vital data from your original module to this new unit, ensuring a seamless transition.
Case Study: The Phantom Battery Drain
A customer brought in their ’09 Impala with a battery that would die overnight. They’d already replaced the battery and alternator, but the problem persisted. After checking for parasitic draws, I noticed the BCM wasn’t letting the vehicle’s accessory circuits go to ‘sleep’ after the key was off. The interior lights would have a faint, almost imperceptible glow. A new, properly programmed BCM solved the issue completely. It’s a perfect example of how a failing Impala Body Control Module can create problems that seem to come from nowhere.
Common Signs of a Failing BCM
If your vehicle is experiencing any of the following, a faulty BCM is the likely culprit. A scan tool may show communication error codes like U0140, U0155, or other ‘U’ codes.
- ✔ Erratic or non-functional power windows, door locks, and interior/exterior lights.
- ✔ The security or anti-theft system activates incorrectly, preventing the car from starting.
- ✔ Dashboard gauges behaving erratically or not working at all.
- ✔ The key fob stops working or functions intermittently.
- ✔ Horn sounding at random or not working when pressed.
- ✔ A persistent parasitic battery drain that kills the battery overnight.
Your Straightforward BCM Installation Guide
For the confident DIYer, replacing the BCM is a manageable job. In the 2006-2013 Impala, it’s typically located behind the driver’s side of the dashboard.
- Safety First: Always disconnect the negative terminal from your car’s battery before working on any electrical components.
- Locate the BCM: On the Impala, you’ll usually find the BCM to the left of the steering column, often behind a lower dash panel. You may need to remove this panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old module. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old BCM from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location. Reconnect all the electrical connectors, ensuring they click securely into place.
- Post-Installation Steps: Reconnect the negative battery terminal. Start the vehicle and test all body functions—lights, locks, windows, etc. Note that some vehicles may require additional relearn procedures as outlined below.
Important Post-Installation Information
While our programming handles the heavy lifting, some GM vehicles require on-vehicle relearn procedures after a new BCM is installed. These are security handshakes between modules.
- Airbag System Sync: If the airbag light is on after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the BCM with the airbag module.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure brake lights and stability control systems function correctly.
Disclaimer: Vehicle systems vary. Always consult a factory service manual or a qualified technician if you are unsure about any step.

Frequently Asked Questions
Frequently Asked Questions
Do I really need to provide my VIN?
Yes, absolutely. Providing your VIN is the only way we can program the module with the correct software and settings for your specific vehicle’s options, ensuring a true plug-and-play installation.
What is the difference between programming and cloning?
Programming involves loading fresh, vehicle-specific factory software using your VIN. Cloning is the process of transferring key data (like security information) from your old module to the new one. We use a combination of these methods to provide the most reliable and seamless replacement possible.
Do I need to send my old BCM back?
No, there is no core charge for this item. For our cloning service, you would send your original module to us. We then perform the service and return your original module along with the newly prepared replacement.
What tools are needed for the post-installation procedures?
The Airbag System Sync and Brake Pedal Position Relearn require a professional-grade bidirectional scan tool, like a GM Tech 2, Snap-on, or Autel scanner. Most basic code readers cannot perform these functions.
Will this fix my ‘Service Theft System’ message?
In many cases, yes. The BCM is a critical part of the Pass-Key/Passlock anti-theft system. A faulty BCM is a very common cause of this warning message and related no-start conditions. Our programming ensures the security data is correctly set for your vehicle.
