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 dash lights, windows that won’t cooperate, a security system that acts up, or even a car that refuses to start can all point to one culprit: a failing Body Control Module (BCM). As the central nervous system for your vehicle’s accessories, when the BCM goes bad, it can create a cascade of frustrating and hard-to-diagnose problems. Forget expensive dealership diagnostics and programming fees. This is the straightforward, reliable fix you’ve been looking for.
This isn’t just a replacement part; it’s a complete service. We utilize a professional cloning service to transfer the vital, vehicle-specific data from your original BCM directly to this replacement unit. This means that when you receive it, it’s truly plug-and-play. No need for a trip to the dealer for costly programming. We handle the complex part so you can get back on the road quickly and confidently.
Case Study: A Tricky Diagnosis
Just last month, a 2011 Impala was brought to my shop. The owner was at his wit’s end. The instrument cluster would randomly go dark, the radio would shut off, and sometimes the car wouldn’t crank, just giving a single click. He’d already replaced the battery and checked the alternator. After connecting my scan tool, I found a series of U-codes (U0140, U0155), indicating a loss of communication with the BCM. These communication failures are a classic sign. Instead of a complex and expensive rewiring job, we identified the internal BCM failure. With our cloning service, we transferred his data to a new unit, and the car was running perfectly in under an hour after the part arrived. It’s a common story for these vehicles, and this is the definitive fix.
Is Your Impala Showing These Symptoms?
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security or anti-theft light is flashing, preventing the car from starting.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ Instrument panel gauges behaving erratically or going completely dead.
- ✔ The radio or infotainment system randomly shuts off or won’t turn on.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0140.
- ✔ Key fobs are no longer recognized by the vehicle.
A Straightforward Guide to Your BCM Installation
For a DIYer or a professional technician, replacing the BCM on a 2006-2013 Impala is a manageable job. The module is typically located on the left-hand (driver’s) side of the dashboard, often behind the lower trim panel near the steering column.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Access the Module: Remove the necessary lower dash panels to gain clear access to the BCM. This may involve 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 pressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New BCM: Mount your newly programmed BCM in the same location and securely reconnect all the electrical harnesses. Ensure they click into place.
- Reassemble and Reconnect: Reinstall the dash panels you removed. Once everything is back together, reconnect the negative battery terminal.
- Final Checks: Start the vehicle and test all body functions—windows, locks, lights, radio, etc.—to confirm the repair was successful.
Important Post-Installation Information
Our cloning service eliminates the need for standard programming, but some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is on after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible professional scan tool. This syncs the airbag system with the BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure proper brake light operation and to keep the traction control system happy.
Disclaimer: Specific requirements can vary. Always consult a factory service manual for your exact vehicle if you are unsure.

Frequently Asked Questions
What is a BCM cloning service and why do I need it?
Cloning is a process where we transfer the unique, vehicle-specific information (like VIN, key fob data, and specific options) from your old BCM to the replacement one. This makes the new module a perfect digital match for your car, allowing you to avoid expensive and time-consuming programming at a dealership.
Do I need to send my original BCM to you?
Yes. For the cloning service to work, we need your original module to extract the necessary data. We will perform the service and ship your original module back to you along with the ready-to-install replacement.
Will this fix my specific electrical problem?
This module corrects issues directly caused by a faulty BCM. The symptoms listed above are strong indicators. If you’re experiencing multiple of those issues, it’s highly likely a failing BCM is the root cause. A proper diagnosis from a qualified mechanic is always the best way to be certain.
Where is the BCM located on my 2006-2013 Impala?
On the 2006-2013 Impala, the Body Control Module is located inside the cabin, on the driver’s side. You’ll typically find it behind the lower dashboard panel, to the left of the steering column.
What do I do if my airbag light is on after installation?
An airbag light after BCM replacement is not uncommon. It simply means the BCM and the Sensing and Diagnostic Module (SDM) need to be re-synced. This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be done by any competent repair shop with a professional-grade scan tool.
