Restore Your Impala’s Electrical System with a Hassle-Free Solution
Are you dealing with baffling electrical issues in your 2006-2013 Chevrolet Impala? Flickering lights, malfunctioning power windows or door locks, a persistent security light, or even a no-start condition can often be traced back to a failing Body Control Module (BCM). As the central hub for your car’s comfort and convenience features, a faulty BCM can make your daily drive a frustrating experience. This isn’t just an inconvenience; it can affect vehicle security and safety systems. We offer a reliable, straightforward solution: a professionally prepared BCM, delivered to your door ready for installation.
From the Diagnostic Bay: The Case of the Haunted Impala
I remember a 2011 Impala that came into my shop with a list of symptoms that sounded like a poltergeist had taken up residence. The radio would change stations on its own, the dome light would stay on, and the remote key fob worked only intermittently. The owner had already replaced the battery and checked all the fuses. After connecting my scan tool, I found a series of communication error codes (U-codes) pointing to a network issue. Experience has taught me that when multiple, unrelated body systems act up simultaneously, the BCM is the prime suspect. We confirmed the diagnosis and used our cloning service to prepare a replacement module. The result? All the ghostly electrical problems vanished. This is a classic BCM failure scenario I’ve seen hundreds of times on this GM platform.
The Power of Cloning: Why Our BCM Service is Different
A new BCM from the dealership requires expensive and time-consuming programming. Our unique Cloning Service eliminates that step entirely. Here’s how it works: you send us your original BCM. We then transfer its vital, vehicle-specific data—including the VIN, security key codes, and other learned parameters—directly to this replacement module. The BCM you receive back is a true plug-and-play component, programmed specifically for your car. This process ensures seamless integration with your vehicle’s existing systems, saving you from a costly trip to the dealer and complex programming procedures.
Common Signs of a Failing BCM
- âś” Erratic or non-functional power windows, door locks, and interior/exterior lights.
- âś” The security or anti-theft light stays on, potentially causing a no-start condition.
- âś” The instrument cluster displays incorrect information or warning lights are falsely triggered.
- âś” Remote keyless entry (fob) stops working or functions sporadically.
- âś” Communication error codes, such as U0140, U0155, or other U-series codes, are stored.
- âś” The radio or climate control systems behave unpredictably.
A Straightforward Guide to Installation
- âś” Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- âś” Locate the BCM: On the 2006-2013 Impala, the BCM is typically located behind the driver’s side of the dashboard, to the left of the steering column. You may need to remove a lower dash panel for access.
- âś” Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, remove any bolts or clips holding the module in place and take it out.
- âś” Install the New Module: Seat your new, pre-programmed BCM in the mounting bracket and secure it. Reconnect all electrical connectors, ensuring they click firmly into place.
- âś” Reconnect Power: Re-attach the negative battery terminal. The vehicle may need to sit for a few minutes for all modules to initialize.
- âś” Verify Operation: Start the car and test all body functions: lights, locks, windows, radio, etc., to confirm the repair is successful. Note the post-installation procedures below.
Post-Installation Procedures & Notes
While our cloning service makes this a near plug-and-play job, some GM vehicles may require a final handshake between modules. Please be aware of the following:
- Airbag System Sync: If the airbag light is illuminated 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 module.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary for proper brake light and traction control operation.
- Your Original Module: We always return your original BCM along with the programmed replacement. We do not keep customer cores.
Disclaimer: Vehicle systems vary. Always consult a factory service manual or a qualified technician if you are unsure about any step of the process.

Why do you need my original BCM?
We need your original BCM for our cloning service. This allows us to extract the unique programming, security information, and vehicle options data and transfer it to the replacement module. This ensures the part you receive is 100% plug-and-play for your specific vehicle.
What happens if I don’t provide my VIN?
The VIN is a critical part of the ordering process. We use it to verify the correct base software and hardware for your vehicle before programming. An order cannot be processed without a valid VIN to ensure compatibility.
Is this a difficult part for a DIYer to install?
For most models, including the 2006-2013 Impala, replacing the Body Control Module is a manageable job for a DIYer with basic tools. It typically involves removing a dash panel and swapping the modules. Our cloning service removes the most difficult part: the computer programming.
Will I get my old BCM back?
Yes, absolutely. Your original module is always returned to you along with the programmed replacement unit. We do not keep customer core parts.
What if the airbag light comes on after installation?
This is a known possibility on some GM vehicles. It means the BCM and the airbag module (SDM) need to be electronically re-introduced. This requires a ‘Setup SDM Primary Key in BCM’ procedure with a bi-directional scan tool, which a professional mechanic can perform.
