Restore Your Impala’s Functionality and End Electrical Frustration
Is your 2006-2013 Chevrolet Impala acting possessed? Flickering lights, malfunctioning power windows, a security system that randomly immobilizes the engine, or a dashboard lit up with warning lights are all classic signs of a failing Body Control Module (BCM). As the central nervous system for your vehicle’s electronics, a faulty BCM can cause a cascade of confusing and frustrating problems. I’ve spent over two decades in the garage, and I can tell you that chasing these electrical gremlins without addressing the root cause is a waste of time and money.
This isn’t just a replacement part; it’s a comprehensive solution. We offer a professional cloning service for your 2006-2013 Impala BCM. This means we transfer the exact data and programming from your original, failing module directly onto this fully functional replacement unit. The result? A true plug-and-play component that restores your car’s factory operations without requiring a costly trip to the dealership for programming. You get your vehicle back to normal, fast.
Case Study: A Tricky Diagnosis
A customer brought in an ’08 Impala with a complaint that stumped two other shops. The car would randomly refuse to start, the radio would shut off, and the power locks would cycle on their own. There were no consistent trouble codes, just a few intermittent U-codes pointing to a communication loss. Instead of just replacing parts, we monitored the BCM’s data stream. We found the voltage outputs to several circuits were dropping sporadically. This confirmed the BCM itself was failing internally, likely from heat-related stress on the circuit board—a common issue on these platforms. A cloned BCM had the car running perfectly in an afternoon, solving all the ghost-like issues at once.
Common Signs of a Failing BCM
If your vehicle is experiencing any of the following, a faulty BCM is the likely culprit. In my shop, these symptoms almost always lead back to this critical component. Don’t let these issues leave you stranded.
- ✔ Erratic or non-functional power windows, door locks, and interior/exterior lights.
- ✔ The security or anti-theft system light stays on, preventing the car from starting.
- ✔ Intermittent dashboard warnings or gauges that behave strangely.
- ✔ Communication-related Diagnostic Trouble Codes (DTCs), such as U0100, U0140, or various B-series codes.
- ✔ Wipers or horn activating on their own or not working at all.
- ✔ Inconsistent A/C compressor clutch engagement.
A Straightforward Guide to Installation
Our cloning service makes this repair accessible for both DIYers and professional technicians. By transferring your vehicle’s original data, we eliminate the most complicated step. For the 2006-2013 Impala, the BCM is typically located on the left (driver’s) side of the dash.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: On most Impalas of this generation, you’ll need to remove the lower dash panel beneath the steering column to access the module.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt the module from its mounting bracket.
- Ship Us Your Module: Securely package your original BCM and send it to us. We will perform the cloning service and ship both your original and the newly programmed replacement module back to you.
- Install the New BCM: Mount the programmed replacement module, reconnect the electrical harnesses, and reinstall any trim panels you removed.
- Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all body functions—lights, locks, windows, wipers, etc.—to confirm the repair was successful.
Important Post-Installation Information
While our cloning service makes this a plug-and-play process for most functions, some vehicle security and safety systems may require a ‘handshake’ with the new module. Be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the modules and clear the light.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure proper brake light and traction control operation.
Disclaimer: Vehicle systems vary. Always have a factory service manual or a qualified technician available for guidance if you are unsure about any step.

Frequently Asked Questions
How does the cloning service work?
After you place your order, you ship your original BCM to us. Our technicians extract the unique vehicle data (for keys, mileage, and options) and flash it onto the replacement module. We then ship both modules back to you, ensuring the replacement is ready for installation with no extra programming.
Do I need to send you my keys or other modules?
No. Because we are cloning the data directly from your old BCM, all your existing keys and settings will be recognized by the new module automatically. You only need to send us the BCM itself.
Will I get my original module back?
Yes, absolutely. We always return your original module along with the programmed replacement unit. We do not keep customer cores.
Is this a difficult part to replace myself?
For someone with basic mechanical skills, it’s a very manageable job. The BCM is typically located under the driver’s side dashboard and held in by a few bolts. The main challenge is usually the programming, which our cloning service completely handles for you.
What if my original BCM is too damaged to be read?
In rare cases of severe water or fire damage where the data cannot be retrieved, we will contact you to discuss other options, which may include programming with your vehicle’s VIN. However, in over 99% of cases, we can successfully clone the data.
