Tired of Chasing Electrical Gremlins in Your Impala?
As a technician with over two decades of experience, I’ve seen it all. A customer comes in with a 2017 Impala, and the story is always the same: the radio cuts out, the power windows have a mind of their own, the security light is flashing, and sometimes, the car won’t even start. These aren’t separate problems; they’re symptoms of a single failing component: the Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s comfort and convenience features. When it fails, it can create a cascade of frustrating and seemingly unrelated issues.
This isn’t just a replacement part; it’s a complete, hassle-free solution. We offer a professional cloning service for the 2015-2020 Impala BCM. You simply send us your original module, and we transfer all the critical vehicle-specific data—like key programming and option configurations—to this fully tested replacement unit. The result? A module that is plug-and-play, saving you hundreds of dollars in dealership programming fees and diagnostic headaches.
Case Study: A Tricky Diagnosis
I remember a 2018 Impala that came into the shop with the instrument cluster lights flickering wildly and an intermittent no-crank condition. The owner had already replaced the battery and checked the alternator. Diagnostic codes were all over the place, mostly communication errors (U-codes). This kind of chaos often points directly to the BCM. Instead of a costly new module and hours of programming at the dealer, we used this exact cloning service. Once the programmed BCM arrived, it was a 30-minute swap. The car started right up, all the lights worked perfectly, and every electronic feature was back online. It’s a reliable fix that gets the job done right the first time.
Common Signs of a Failing BCM
- ✔ Intermittent or non-functional power windows, locks, or mirrors.
- ✔ Erratic instrument cluster behavior (flickering lights, dead gauges).
- ✔ Radio or infotainment system randomly shutting off.
- ✔ Security system faults or anti-theft light staying on, preventing the car from starting.
- ✔ Communication error codes, such as U0140, on a diagnostic scan.
- ✔ Interior or exterior lights not working correctly.
A Straightforward Guide to Installation
Our cloning service makes the physical replacement simple. After you receive the programmed module from us, follow these general steps:
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: On the 2015-2020 Impala, the BCM is typically located on the left-hand (driver’s side) of the dashboard, often near the steering column or A-pillar.
- Remove Trim Panels: You may need to remove lower dash panels or kick plates to gain access. Take your time and use a trim removal tool to avoid breaking any clips.
- 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 newly programmed BCM in the same location, reconnect all the electrical harnesses securely, and reinstall any trim panels.
- Reconnect Battery: Reattach the negative battery terminal. Your vehicle’s essential functions should now be restored.
Important Post-Installation Notes
While our cloning service handles the primary programming, some vehicle systems may require a simple relearn procedure to fully sync with the new BCM. This is normal for modern vehicles.
- Airbag System Sync: If you see an airbag warning light after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure proper brake light and traction control operation.
Disclaimer: Procedures can vary. Always consult a factory service manual or a qualified technician if you are unsure about any step.

What is a “cloning” service?
Cloning is a process where we read the unique, vehicle-specific software and security data from your original BCM and write it directly onto the replacement module. This ensures the new part is a perfect digital match for your car, avoiding the need for expensive dealership programming.
Do I need to program this module after I receive it?
No. Because we clone your original data, this BCM will arrive ready for installation. In most cases, it is a true plug-and-play solution. Some vehicles may require minor relearn procedures for systems like the airbag or brake pedal sensor, as noted above.
How does the mail-in process work?
After you place your order, we will contact you with detailed instructions on how to ship your original BCM to our facility. Once we receive it, we perform the cloning service and ship your new, programmed module back to you, typically within 1-2 business days. We’ll provide tracking information for the return shipment.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM has failed, the core data on the memory chip is still readable. We have specialized tools to extract this data. Please contact us if your module is severely damaged (e.g., by water or fire) to discuss options.
Is there a core charge for this part?
No, there is absolutely no core charge. You can keep your original module after you send it to us for the data transfer.
