Restore Full Functionality to Your 2006-2013 Chevrolet Impala
If you’re dealing with baffling electrical issues in your 2006-2013 Chevy Impala—like power windows with a mind of their own, flickering dash lights, or a security system that prevents your car from starting—you’ve likely met the culprit: a failing Body Control Module (BCM). As a technician with over two decades of experience, I’ve seen how a faulty BCM can turn a reliable car into a source of daily frustration. It’s the central hub for your vehicle’s body electronics, and when it fails, chaos ensues. This isn’t just an inconvenience; it can be a serious safety issue.
Forget expensive dealership visits and the hassle of programming a new module from scratch. We offer a straightforward, reliable solution. This is a replacement Body Control Module, compatible with part number 15880684, that comes with our expert cloning service. You send us your original BCM, and we transfer all its critical data—including VIN, mileage, and key information—to this replacement unit. The result? A true plug-and-play module that restores your Impala’s electrical systems to factory condition without any additional programming required on your end.
Case Study: A Tricky Diagnosis
A customer brought in a 2011 Impala with a classic BCM failure symptom: the radio and interior lights would randomly shut off while driving. They had already replaced the battery and checked the alternator, but the problem persisted. After hooking up my diagnostic scanner, I pulled a U0140 code (Lost Communication With Body Control Module). While this pointed to the BCM, the intermittent nature of the fault made it tricky. By monitoring the data stream, I saw the BCM was dropping offline due to internal voltage regulation failure, a common issue on these units caused by heat cycling over many years. Replacing it with a cloned module solved the problem instantly, saving the customer hundreds compared to the dealership’s quote for a new module and programming.
Common Signs of a Failing BCM
A failing 2006-2013 Impala BCM can cause a wide range of symptoms. If you’re experiencing any of the following, it’s time to consider a replacement:
- ✔ Erratic power windows, door locks, or interior lighting
- ✔ Horn honking unexpectedly or not working at all
- ✔ The security or anti-theft light is on, causing a no-start condition
- ✔ Dashboard warning lights appearing for no reason
- ✔ Communication error codes, such as U0140, U0155, or other U-series codes
- ✔ Wipers or turn signals functioning intermittently
A Straightforward Guide to Installation
Installing your cloned BCM is a manageable job for a DIYer with basic tools. For the 2006-2013 Impala, the BCM is typically located on the left (driver’s) side of the dash, often near the steering column.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts. Wait at least 10 minutes for the system capacitors to discharge.
- Locate the BCM: On most Impalas of this generation, you’ll need to remove the lower dash panel beneath the steering wheel to gain access. It’s a black box with several large electrical connectors.
- Disconnect and Remove: Carefully unplug all wiring harnesses from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Mount your new, cloned BCM in the same location and securely reconnect all the wiring harnesses. You should hear a ‘click’ as they lock into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions: windows, locks, lights, wipers, and radio. Start the vehicle to ensure it runs correctly.
Important Post-Installation Information
Our cloning service makes this a nearly seamless process. However, in some vehicles, a few additional steps may be required. Please be aware of the following:
- Airbag System Sync: If the airbag (SRS) light is on after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade scan tool. This syncs the BCM with the airbag module.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn might be needed to ensure correct brake light operation and to prevent issues with the traction control system.

Frequently Asked Questions
Frequently Asked Questions
How does the cloning service work?
After you place your order, you’ll ship your original BCM to us. We use specialized equipment to extract the unique data from your module and flash it onto the replacement unit. We then ship both your original module and the ready-to-install replacement back to you.
Do I need to get this programmed by a dealer?
No. Our cloning service completely eliminates the need for dealership programming. Because we transfer your vehicle’s original data, the replacement BCM is plug-and-play.
What is your core policy?
We require your original BCM to perform the cloning service. However, we do not keep it. Your original module will always be returned to you along with the newly programmed replacement unit.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is failing, we can still extract the necessary data. If your module is severely damaged (e.g., by fire or water), please contact us before ordering to discuss options. In some cases, we can program a unit using your VIN.
Will this fix my ‘Service Theft System’ message?
Yes, a faulty BCM is a very common cause of anti-theft system errors on the 2006-2013 Impala. By cloning your original key data, this replacement BCM will resolve security-related no-start issues caused by the module itself.
