Restore Your Vehicle’s Electrical System with a Plug-and-Play Solution
Are you battling frustrating electrical gremlins in your 2015-2016 Chevrolet Impala? Issues like flickering lights, malfunctioning power windows and locks, or a security system that acts up on its own are often signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your car’s comfort and convenience features. When it fails, it can make your vehicle feel unreliable and unpredictable. Dealerships often charge a fortune for a replacement and the necessary programming. We offer a simpler, more affordable path forward.
This is a fully tested replacement BCM that comes ready for installation, thanks to our professional cloning service. The process is straightforward: after your purchase, you’ll ship your original BCM to us. We will then transfer all the specific software, key data, and vehicle-specific settings from your module to this replacement unit. This ensures a seamless match for your car’s options and security system. We ship the programmed module back to you, ready to be installed without any need for a trip to the dealer for expensive programming.
Case Study: A Tricky Diagnosis
A customer brought in a 2015 Impala with a complaint that was driving them crazy: the interior dome lights would randomly turn on while driving, and the driver’s side power window would only work intermittently. They had already replaced the window switch and checked fuses with no luck. In the shop, my first step was to scan for codes. I found a slew of U-codes (Communication Errors) pointing to the BCM. After verifying the power and ground connections to the BCM were solid—a critical first step I’ve seen many technicians skip—it was clear the module itself was the culprit. Internal circuit board failures can cause these bizarre, unrelated symptoms. We replaced it with one of our programmed modules, and all the ghost-like electrical issues were resolved instantly. This is a classic BCM failure scenario.
Common Signs of a Failing BCM
- ✔ Power windows, door locks, or mirrors operate erratically or not at all.
- ✔ Interior or exterior lights flicker, stay on, or won’t turn on.
- ✔ The vehicle’s security system or horn activates randomly.
- ✔ The instrument cluster displays incorrect information or warning lights (like the airbag light).
- ✔ Your key fob stops working reliably.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors (U-codes) are stored in the system.
- ✔ Intermittent no-start condition where the starter doesn’t engage.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes for the system to fully discharge.
- ✔ Locate the BCM: On the 2015-2016 Impala, the BCM is typically located behind the lower left side of the dashboard, near the steering column. Access may require removing a lower dash panel.
- ✔ 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.
- ✔ Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely reconnect all the electrical connectors. Ensure they click into place.
- ✔ Reconnect Power: Reinstall any trim panels you removed and reconnect the negative battery terminal.
- ✔ Test and Verify: Start the vehicle and test all body functions—windows, locks, lights, wipers, etc.—to confirm the repair.
Important Post-Installation Notes
While our cloning service makes this a near plug-and-play repair, some vehicle systems may require a ‘handshake’ with the new BCM. If your airbag light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Similarly, some models may require a Brake Pedal Position Relearn for proper brake light and traction control operation. Always consult a factory service manual for your specific vehicle if you are unsure.

Frequently Asked Questions
How does the cloning service work?
After you place your order, we will contact you with instructions to ship your original BCM to our facility. Once we receive it, our technicians will extract the vehicle-specific data and transfer it to the replacement module. This makes the new module a perfect electronic match for your car.
How long does the entire process take?
We typically program and ship your replacement BCM within 1-2 business days of receiving your original module. The total time will depend on shipping times to and from our facility.
Is this a guaranteed fix for my vehicle’s problems?
This BCM will fix problems directly caused by a faulty module. It’s crucial to ensure your vehicle has been properly diagnosed. This part will not fix issues caused by bad wiring, faulty sensors, or other components.
Do I need to send my keys with the BCM?
No, you do not need to send your keys. Our cloning process transfers all the necessary security information from your old BCM, so your existing keys will work perfectly upon installation.
What if the airbag light comes on after I install it?
In some cases, the new BCM needs to be electronically introduced to the airbag system (SDM). This is a simple procedure called ‘Setup SDM Primary Key in BCM’ that can be performed by any professional mechanic with a capable diagnostic scan tool.
