Restore Your Impala’s Electrical System with a Hassle-Free Solution
Is your 2006-2013 Chevy Impala acting possessed? Flickering lights, power windows with a mind of their own, or a security light that won’t turn off are classic signs of a failing Body Control Module (BCM). As the central hub for your car’s body electronics, when the BCM goes down, it creates a cascade of frustrating and unpredictable problems. Instead of facing a costly trip to the dealership for a new module and expensive programming, our professional cloning service offers a direct, reliable, and affordable fix.
We take the essential data from your original BCM—including key information and vehicle-specific settings—and transfer it directly to this replacement unit. The result? A module that is truly plug-and-play for your specific vehicle. No additional programming, no security relearn procedures, and no surprise fees. This is the straightforward solution that gets your Impala back to normal, fast.
A Technician’s Notebook: The Telltale Signs of BCM Failure
I remember a 2011 Impala that came into the shop with a laundry list of bizarre symptoms. The owner complained that the radio would randomly shut off, the dome light would stay on, and occasionally the car wouldn’t start, showing only a ‘Service Theft System’ message. A scan tool showed multiple ‘loss of communication’ codes (U-codes) with various modules. While these symptoms could point to a wiring issue, my experience with this platform led me straight to the BCM, located on the left side of the dash. Sure enough, after a quick inspection, we found evidence of minor water intrusion from a leaky A-pillar seal that had corroded a few pins on the BCM connectors. A cloned BCM restored full functionality instantly, saving the customer hundreds compared to the dealer quote.
Common Symptoms of a Failing BCM
If you’re experiencing any of the following issues, a faulty BCM is the likely culprit. A failing module can often set communication codes like U0140, U0155, or U0100.
- ✔ Power windows, door locks, or mirrors operate intermittently or not at all.
- ✔ Interior or exterior lights flicker, stay on, or won’t turn on.
- ✔ The security or anti-theft system light is illuminated, preventing the car from starting.
- ✔ The horn honks unexpectedly or doesn’t work.
- ✔ Dashboard warning lights appear randomly.
- ✔ Remote keyless entry (RKE) is unresponsive.
A Straightforward Guide to Installation
Installing your cloned BCM is a simple process that most DIYers can handle with basic tools. For the 2006-2013 Impala, the BCM is typically located behind the lower dash panel on the driver’s side.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Access the Module: Carefully remove the lower dash panel beneath the steering column to expose the BCM. It’s a black plastic box with several large electrical connectors.
- Disconnect and Remove: Depress the locking tabs on each electrical connector and gently pull them straight out. Once all connectors are removed, unbolt or unclip the old BCM from its mounting bracket.
- Install the Replacement: Mount your new, cloned BCM onto the bracket and securely plug in all the electrical connectors. You should hear a ‘click’ as they lock into place.
- Final Steps: Reinstall the lower dash panel and reconnect the negative battery terminal. Start the vehicle to confirm that the electrical issues are resolved.
Important Post-Installation Information
While our cloning service makes this a near plug-and-play process, some GM vehicles may require simple relearn procedures after the battery has been disconnected or a new module is installed.
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure may be needed. This requires a professional-grade scan tool to sync the modules and is not a common requirement, but can happen.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure proper brake light and traction control operation. This is also performed with a capable scan tool.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What is a BCM cloning service?
Cloning is a process where we transfer the critical vehicle-specific data (like VIN, key codes, and option configurations) from your original, failing BCM to this replacement unit. This makes the replacement module a perfect electronic match for your car, eliminating the need for expensive dealer programming.
Do I need to send my original BCM to you?
Yes. For the cloning service to work, you must send us your original module after you complete your purchase. We will perform the service and ship both your original module and the ready-to-install replacement back to you.
Is this really plug-and-play?
Yes, in over 95% of cases. Because we clone your original data, the car recognizes the new module as its own. In rare cases, a simple relearn procedure as noted in our description may be required, but the expensive, security-related programming is completely avoided.
Why is my original module returned?
We always return your original part. It contains your vehicle’s unique data and is your property. This policy ensures complete transparency and gives you peace of mind.
How do I know for sure that my BCM is the problem?
While the symptoms listed are strong indicators, a proper diagnosis is always recommended. This can involve checking for specific BCM-related diagnostic trouble codes (DTCs) and verifying power and ground at the module. If you’re unsure, consult a professional mechanic.
