Are you tired of chasing down bizarre electrical gremlins in your Buick Verano or other GM vehicle? One minute the power windows work, the next they don’t. The security light flashes for no reason, or worse, the car refuses to start. As a technician with over two decades of experience, I’ve seen these exact frustrations countless times. The culprit is often a failing Body Control Module (BCM)—the central command center for your car’s body electronics.
This isn’t just a replacement part; it’s a complete, hassle-free solution. We offer a professional cloning service for this BCM, part number 13586273. This means we transfer all the critical vehicle-specific data from your original, faulty module to this fully functional replacement. The result? A true plug-and-play module that requires no expensive trip to the dealership for programming. It restores function and communication just like the original did when it was new.
Common Signs of a Failing GM BCM
A bad BCM can cause a cascade of confusing issues because it controls so many different systems. If you’re noticing any of the following, a faulty BCM is a likely cause:
- ✔ Erratic or non-functional power windows, door locks, and interior/exterior lights.
- ✔ The security system engaging randomly, preventing the car from starting (anti-theft light on).
- ✔ Intermittent starting problems or a complete no-start condition.
- ✔ Dashboard warning lights (like Airbag, ABS, or Traction Control) illuminating without a clear cause.
- ✔ Diagnostic trouble codes (DTCs) related to lost communication, such as U0140, U0155, or other U-codes.
- ✔ The horn honking or wipers activating unexpectedly.
A Technician’s Notebook
I remember a 2015 Chevy Cruze that came into the shop with a laundry list of complaints from the owner. The radio would cut out, the driver’s side window was stuck, and the key fob worked only intermittently. The owner had already replaced the battery and checked fuses with no luck. After connecting my scan tool, I saw a dozen ‘Lost Communication with BCM’ codes. Instead of a dozen separate problems, it was one root cause. By swapping in a cloned 2013-2017 Verano BCM (which shares this platform), we had all systems back online in under an hour. It’s a classic case of the BCM failing and taking the whole network down with it.
A Straightforward Guide to Your BCM Swap
Our cloning service makes the physical replacement simple. Once you receive the programmed module from us, follow these general steps. The BCM location varies by model (see fitment list), but the process is similar.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate Your BCM: On a Verano, it’s typically below the center of the dash. For other models like the Cruze or Malibu, it’s often behind the driver’s side kick panel.
- Remove Connectors: Carefully unplug all electrical connectors from the old BCM. They have locking tabs, so don’t force them. A small flathead screwdriver can help depress the tabs.
- Swap the Module: Unbolt or unclip the old BCM from its mounting bracket and install the new, programmed module in its place.
- Reconnect Everything: Plug all the electrical connectors firmly into the new BCM. You should hear a click. Reconnect the negative battery terminal.
- Test Functionality: Start the vehicle and test all the systems that were previously malfunctioning—windows, locks, lights, etc.
Important Post-Installation Steps
In most cases, this module is a direct plug-and-play fix. However, in some vehicles, a couple of quick relearn procedures may be needed:
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system to the new BCM.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration may be necessary on certain models.
Disclaimer: Always consult a factory service manual for procedures specific to your vehicle’s make and model.
How Our Simple Cloning Service Works
Getting your vehicle fixed is easy. After you purchase, we will contact you with instructions to ship your original BCM to our facility. Once we receive it, our experts will clone its data onto the replacement module and ship it right back to you, typically within 24-48 hours. This process ensures all your vehicle’s options and security information are perfectly matched. And with no core charge, you can keep your original module.

Frequently Asked Questions
How does the mail-in cloning service work?
After you place your order, we’ll email you a shipping label and instructions. You securely pack and send us your original BCM. Once we receive it, we transfer the data to the new module and ship it back to you, ready for installation.
Is this truly plug-and-play?
Yes, because we clone your vehicle’s original data, the replacement module is recognized by your car’s other computers. This eliminates the need for expensive dealership programming. Some models may require a simple relearn procedure as noted above.
What if my original BCM is completely dead or unreadable?
In most cases, even with significant internal damage, we can still extract the necessary data. If for some reason your module’s data is completely corrupted, we will contact you to discuss options, which may include a full refund.
Do I need special tools for the installation?
For most models, basic hand tools like a socket set and screwdrivers are all you need to access and swap the BCM. The most important part is being able to locate the module in your specific vehicle.
Why is my airbag light on after installing the new BCM?
This can happen because the airbag system (SDM) needs to re-establish its security handshake with the new BCM. A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
