Restore Full Electrical Function to Your 2006-2013 Impala
Are you battling frustrating electrical issues in your Chevrolet Impala? Flickering interior lights, malfunctioning power windows, or a security system that acts on its own are classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of confusing problems. This isn’t just an annoyance; it can affect vehicle safety and operation. This replacement 2006-2013 Impala Body Control Module is the definitive solution to get your car back to factory-spec performance without the exorbitant cost and hassle of a dealership visit.
A Technician’s Notebook: The ‘Ghost in the Machine’
I’ve seen hundreds of GM vehicles, especially Impalas and Acadias, come into my bay with what owners describe as a ‘ghost in the machine.’ The radio might change stations, the door locks cycle while driving, or the anti-theft light stays on, preventing the car from starting. In over 90% of these cases, the root cause is a failing BCM. Often, this is due to internal circuit board corrosion from moisture exposure or simple electronic fatigue after years of service. Don’t waste time and money replacing individual switches or sensors; a faulty BCM is the most common culprit for these widespread electrical gremlins.
The Power of Our Cloning Service
What makes this part special is our complimentary cloning service. A new BCM from the dealer requires expensive and time-consuming programming to sync with your vehicle’s unique systems. Our process eliminates that step entirely. We transfer the critical data—including your Vehicle Identification Number (VIN), key codes, and other vehicle-specific settings—from your original module directly onto this replacement unit. The result? A BCM that arrives at your door ready for a simple, plug-and-play installation. No special tools, no trip to the mechanic for programming. We simply require your VIN after purchase to perform this service before we ship the part to you.
Common Signs of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ The security or anti-theft light stays illuminated, potentially causing a no-start condition.
- ✔ Inaccurate readings on the instrument cluster gauges.
- ✔ Intermittent operation of the radio or climate control system.
- ✔ Diagnostic Trouble Codes (DTCs) related to communication errors, such as U0140, U0155, or other ‘U’ codes.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- ✔ Locate the BCM: On a 2006-2013 Impala, the Body Control Module is typically located on the left-hand (driver’s) side of the dashboard, often behind the lower dash panel near the steering column.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have release tabs that need to be pressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Mount the new, pre-programmed BCM in the same location and securely reconnect all the electrical connectors. You should hear a ‘click’ as they lock into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the ignition to the ‘On’ position and test all body functions—lights, windows, locks, radio, etc.—to confirm the repair.
- ✔ Post-Installation Checks: As noted in our procedures, a brake pedal position relearn or airbag system sync may be required in some cases. Please see the FAQ section for more details.

Frequently Asked Questions
Frequently Asked Questions
What is a ‘cloning service’ and why do I need it?
Cloning is a service where we transfer your vehicle’s specific data (like VIN, mileage, and key information) from your old BCM to the replacement one. This makes the module plug-and-play, saving you from needing expensive programming at a dealership.
Do I need to send my original BCM to you?
Yes. For our 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 and the newly programmed replacement back to you promptly.
Where is the BCM located on my 2011 Impala?
On the 2006-2013 Impala, the BCM is typically found behind the lower dash panel on the driver’s side, near the steering column and fuse box area.
What if my airbag light comes on after installation?
This is uncommon, but if it happens, it means the BCM and the airbag module (SDM) need to be re-synced. A professional mechanic with a capable scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve it.
Is any other programming required after I install it?
In most cases, no other programming is needed. However, some vehicles may require a ‘Brake Pedal Position Sensor Relearn’ procedure, which can often be done without special tools or by a local shop if needed. This ensures your brake lights and traction control work correctly.
Will this fix my car’s no-start problem?
If your no-start issue is caused by the anti-theft system being triggered by a faulty BCM (a very common issue), then yes, this part will resolve the problem once the correct key data is cloned over.
What is your core policy?
We do not keep your original module. The cloning service requires your original part, which is always returned to you along with the programmed replacement unit. There is no separate core charge.
