Restore Your Impala’s Electrical System with a Hassle-Free Solution
If your 2006-2013 Chevy Impala is suddenly possessed by electrical gremlinsāpower windows with a mind of their own, flickering dash lights, or a security system that prevents it from startingāthe Body Control Module (BCM) is the most likely culprit. As a technician with over two decades of experience, I’ve seen firsthand how a failing BCM can turn a reliable car into a source of daily frustration. It’s the central nervous system for your vehicle’s comfort and security features, and when it goes, chaos ensues.
Don’t get stuck with a massive repair bill from the dealership. Their process often involves installing a new, blank module and charging hundreds for programming. We offer a smarter, more efficient path. This isn’t just a replacement part; it’s a complete Cloning Service. You send us your original BCM, and we professionally transfer all of its critical dataāincluding your VIN, mileage, and key programmingāto this fully tested replacement unit. The result? A true plug-and-play module that is ready for installation right out of the box, saving you time, money, and a trip to the dealer.
A Technician’s Notebook
I remember a 2011 Impala that came into the shop with the owner at his wit’s end. The radio would turn on and off randomly, the driver’s side window wouldn’t go down, and the “Service Theft System” light was on, causing intermittent no-start issues. Another shop had already replaced the battery and alternator to no avail. After a quick scan, I saw multiple U-codes (communication errors) pointing to the BCM. Instead of a costly new module and programming, we used our cloning service. The customer sent us his faulty BCM, we cloned it, and sent the replacement back. He installed it himself in under 30 minutes. It’s a perfect example of how correctly diagnosing and addressing the root cause with the right service saves hundreds of dollars and unnecessary repairs.
Is Your Impala Showing These BCM Failure Signs?
- ā Erratic or non-functional power windows, door locks, or mirrors.
- ā Interior dome lights or exterior lights staying on or not working at all.
- ā The security or anti-theft light is illuminated, often causing a no-start condition.
- ā Horn honking unexpectedly or not working when pressed.
- ā Instrument cluster gauges behaving erratically or going dead.
- ā Diagnostic trouble codes (DTCs) related to communication loss, such as U0140, U0155, or other U-codes.
- ā Wipers turning on by themselves or not responding to the switch.
Your Straightforward BCM Installation Guide
Installing your cloned 2006-2013 Impala Body Control Module is a job most DIYers can handle. For the Impala, the BCM is typically located behind the driver’s side of the dashboard, to the left of the steering column.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait about 10 minutes to ensure all systems are powered down.
- Access the Module: You may need to remove the lower dash panel beneath the steering wheel to gain access to the BCM. It’s usually held in place by a few screws or clips.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, remove the module from its mounting bracket.
- Install the New Module: Seat the replacement BCM into the mounting bracket and securely plug in all the electrical connectors. You should hear a click as they lock into place.
- Reassemble and Reconnect: Reinstall the dash panel. Reconnect the negative battery terminal.
- Test Functionality: Start the car and test all body functions: windows, locks, lights, wipers, and radio to confirm the repair was successful. Note the post-install procedures below.
Important Post-Installation Steps
Because our cloning service handles the main programming, your vehicle should start and run. However, on some GM models, additional system handshakes may be required:
- Airbag System Sync: If the airbag warning light is on 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 certain models, a brake pedal position sensor relearn may be needed to ensure correct brake light and traction control operation.
Disclaimer: We always return your original module with your replacement unit. Procedures can vary slightly by year and model. Always consult a factory service manual for your specific vehicle.

Frequently Asked Questions
Frequently Asked Questions
What exactly is a BCM cloning service?
It’s a process where we transfer the vehicle-specific software and security data from your original, failing BCM directly onto a replacement module. This makes the new part recognize your car’s keys and options, avoiding the need for dealer programming.
So I don’t need to take my car to the dealer for programming?
That’s correct. Our cloning service makes this a plug-and-play repair. You simply install the module we send you, and you’re ready to go, though minor relearn procedures may be needed in some cases as noted above.
Where is the BCM located on my 2009 Chevy Impala?
On the 2006-2013 Impala, the BCM is located on the driver’s side, behind the lower dashboard panel and to the left of the steering column.
What do I do if my airbag light comes on after installation?
This is a known possibility on some GM vehicles. It means the new BCM needs to be electronically ‘introduced’ to the airbag module (SDM). A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Do I get my original module back?
Yes. We always ship your original module back to you along with the programmed replacement unit. We do not keep customer cores.
Will this fix the ‘Service Theft System’ message on my dash?
In the vast majority of cases, yes. The ‘Service Theft System’ message is one of the most common symptoms of a failing BCM, as it controls the Pass-Key/Pass-Lock security system. A cloned BCM restores this function.
