Restore Full Functionality to Your Chevrolet Impala
Are you dealing with baffling electrical issues in your 2006-2013 Chevrolet Impala? Flickering interior lights, power windows with a mind of their own, or a security system that randomly acts up are classic signs of a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can cause a cascade of frustrating and unpredictable problems. This isn’t just an annoyance; it can affect vehicle security and safety. We offer a dependable and straightforward solution: a professionally prepared BCM with a cloning service that gets you back on the road without the dealership hassle.
Our process is designed for simplicity and reliability. When you order, you provide us with your vehicle’s VIN. We then transfer the essential data from your original BCM to this replacement unit. This means the module arrives at your door ready for installation, bypassing the need for expensive and time-consuming programming at a dealership. It’s the most efficient way to solve complex electrical gremlins and restore your Impala’s comfort and convenience features.
A Technician’s Notebook
I remember a 2011 Impala that came into the shop with a complaint of the radio display and interior lights pulsing at night. The owner had already replaced the battery and alternator. A scan showed multiple U-codes, indicating a communication breakdown between modules. After checking the main network connections, we isolated the fault to the BCM. A failing internal voltage regulator inside the original module was causing the network instability. Installing a properly prepared BCM with the original vehicle data resolved all the flickering and communication codes in one go. It’s a common failure point I’ve seen dozens of times on this platform.
Key Symptoms of a Failing BCM
If your vehicle is showing these signs, a faulty BCM is the likely culprit. A proper diagnosis is always recommended, but these are strong indicators:
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ The security system or keyless entry system malfunctioning.
- ✔ The horn sounding unexpectedly or not working.
- ✔ Dashboard warning lights (like the airbag or security light) illuminating without a clear cause.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0140, U0155, or other U-series codes.
A Straightforward Guide to Installation
Replacing the 2006-2013 Impala Body Control Module is a manageable job for a confident DIYer. For the Impala, the BCM is typically located on the left (driver’s) side of the dash.
- Step 1: Safety First. Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Step 2: Access the Module. You may need to remove the lower dash panel or knee bolster below the steering column to gain access to the BCM.
- Step 3: Disconnect and Remove. Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Step 4: Install the New BCM. Mount the new module in the same location and securely plug in all electrical connectors. You should hear a click as they lock into place.
- Step 5: Reconnect and Test. Reconnect the negative battery terminal. Turn the key to the ‘ON’ position and test all body functions: lights, locks, windows, horn, and wipers.
- Step 6: Perform Relearn Procedures. If necessary, perform the post-installation procedures noted below, such as the Airbag System Sync or Brake Pedal Position Relearn, which may require a professional scan tool.

Frequently Asked Questions
Frequently Asked Questions
How does the cloning service work?
After your purchase, you will send us your original Body Control Module. We extract the critical vehicle-specific data and transfer it to the replacement unit. This ensures it works seamlessly with your car’s existing systems, including the keys and security features, without needing a trip to the dealer.
Do I need to send you my VIN?
Yes, providing your VIN is essential. We use it to load the latest GM software updates for your specific vehicle onto the module, ensuring optimal performance and compatibility before we even perform the cloning.
What happens to my old BCM?
We always return your original module to you along with the newly prepared replacement unit. We do not keep your original part.
Will I need a scan tool after installation?
In many cases, the module is plug-and-play. However, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure if the airbag light comes on, or a ‘Brake Pedal Position Relearn’. These procedures require a professional-grade diagnostic tool.
Is this a difficult part to install myself?
For someone with basic mechanical skills, it is a manageable task. The BCM in an Impala is generally accessible under the driver’s side dashboard. The main challenge is accessing it, not the physical replacement itself. Please refer to our installation guide above.
