Restore Your Vehicle’s Electrical System with a Hassle-Free Solution
Are you battling bizarre electrical issues in your 2012 Buick Verano? Flickering lights, unresponsive power windows, or a security system that randomly prevents your car from starting are classic signs of a failing Body Control Module (BCM). As an automotive technician with over two decades of experience, I’ve seen how a faulty BCM can turn a reliable vehicle into a source of constant frustration. It’s the central command center for your car’s body electronics, and when it goes, it creates chaos.
Forget the expensive dealership visit and the long wait for programming appointments. This is a complete, ready-to-install solution. We provide a fully compatible replacement BCM, part number 13588446, that is professionally programmed using the data from your original module. This cloning process ensures that the replacement BCM is a perfect match for your vehicle’s specific configuration, including the VIN and security information. The result is a seamless repair that gets you back on the road quickly and affordably.
A Technician’s Notebook: The Verano with a Mind of Its Own
A customer brought in a 2012 Verano that was driving them crazy. The radio would switch off, the dome light would stay on, and occasionally the turn signals wouldn’t work. They had already replaced the battery and checked fuses with no luck. A scan showed a handful of U-codes (communication errors) pointing to a network issue. Instead of chasing electrical ghosts for hours, we went straight to the source: the BCM. A failing module was corrupting the data bus. A pre-programmed 2012 Verano BCM like this one would have been the perfect fix, saving the customer hundreds in diagnostic labor and dealer programming fees.
How Our Simple Cloning Service Works
Our process is designed for your convenience. After you place your order, we will contact you with clear, simple instructions for shipping your original BCM to our facility. Once we receive it, our expert technicians will transfer all the critical data to the replacement module. We then ship the newly programmed BCM back to you, typically within one business day. You’ll receive tracking information so you know exactly when it’s arriving. It’s the most straightforward way to get a properly configured part without leaving your home.
Is Your Verano Exhibiting These Electrical Gremlins?
- ✔ Power windows, door locks, or interior lights operate erratically or not at all.
- ✔ The anti-theft or security light is illuminated, and the engine won’t start.
- ✔ Dashboard warning lights (like ABS or Airbag) appear for no reason.
- ✔ The horn honks unexpectedly or the remote keyless entry fails.
- ✔ Diagnostic scans show communication error codes (U-codes) with other modules.
- ✔ Wipers or radio turn on and off by themselves.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- ✔ Locate the BCM: In the 2012 Buick Verano, the Body Control Module is located below the center of the dashboard, often requiring the removal of a lower trim panel for access.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. Note their orientation. Then, unfasten any bolts or clips holding the module in place and remove it from the vehicle.
- ✔ Install the New Module: Mount your new, pre-programmed BCM in the same location and securely fasten it. Reconnect the electrical connectors to their corresponding ports.
- ✔ Reconnect Power: Reattach the negative battery terminal. The vehicle will now recognize the cloned BCM, and most functions should be immediately restored.
Important Post-Installation Information
While our cloning service handles the primary programming, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If the 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 with the new module.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light and traction control operation.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any step.

Frequently Asked Questions
What exactly is a BCM cloning service?
It’s a process where we transfer the essential vehicle-specific software from your original, failing BCM to this replacement unit. This makes the new module plug-and-play, as it already contains your car’s VIN, security keys, and option configuration, eliminating the need for expensive dealership programming.
Do I need special tools to install this 2012 Verano BCM?
Basic hand tools are typically all that’s needed for the physical installation. However, as noted, in some cases a professional diagnostic scan tool may be required for post-installation procedures like syncing the airbag system or relearning the brake pedal position sensor.
Will this fix my car’s no-start problem?
If the no-start is caused by the BCM’s role in the anti-theft system (a very common failure), then yes, this programmed module is the correct solution. It will restore communication and allow the engine to start.
Where is the BCM located on my 2012 Buick Verano?
The Body Control Module on a 2012 Verano is situated in the cabin, underneath the center of the dashboard. You may need to remove the lower dash trim panel on the driver’s or passenger’s side for access.
Is there a core charge or do I need to send my old part back?
There is no core charge. You only need to send us your original module for the data cloning service. After the service is complete, you can keep your original module.
What happens if my airbag light comes on after I install it?
This can happen because the airbag system (SDM) needs to be electronically introduced to the new BCM. A technician with a compatible scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
