Restore Your Vehicle’s Electrical System with a Plug-and-Play BCM
Are you dealing with baffling electrical issues in your Buick Verano or other GM vehicle? Flickering lights, malfunctioning power windows, a dead instrument cluster, or a car that refuses to start are classic 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 feel like your vehicle has a mind of its own. This isn’t just an annoyance; it can be a significant safety concern. We offer a simple, reliable solution that gets you back on the road without the exorbitant costs and complexities of a dealership visit.
Our service provides a fully programmed BCM, ready for installation. Here’s how it works: after your purchase, we’ll coordinate with you to ship your original BCM to our facility. Our expert technicians will then transfer all the critical vehicle-specific data—including VIN, mileage, and key information—from your old module to this replacement unit. This cloning process makes the replacement truly plug-and-play. You avoid towing fees, dealership programming charges, and the hassle of key relearn procedures. It’s the most efficient way to solve your BCM problems.
I remember a 2015 Verano that came into the shop with a list of symptoms that drove the owner crazy. The radio would turn on and off randomly, the driver’s side window wouldn’t go down, and the remote keyless entry worked only intermittently. The owner had already replaced the battery and checked fuses with no luck. After connecting my scan tool, I found a series of U-codes (U0140, U0155) indicating a loss of communication with the BCM. This confirmed my suspicion. Instead of a costly new module from the dealer, we used a cloned BCM. The installation took less than an hour, and instantly, every single electrical gremlin was gone. The customer saved hundreds and avoided a multi-day stay at the dealership.
Common Signs of a Failing BCM
If your vehicle is exhibiting these symptoms, a faulty BCM is the most likely culprit. A failing module can often set communication trouble codes (U-codes) or specific BCM-related faults.
- ✔ 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 security system acts up, causing false alarms or preventing the car from starting.
- ✔ The instrument cluster is dead or displays incorrect information.
- ✔ Remote keyless entry fails to work consistently.
- ✔ The vehicle won’t start, and you hear a rapid clicking sound, even with a good battery.
A Straightforward Guide to Installation
Once you receive the programmed module from us, installation is straightforward. The BCM in the 2013-2017 Verano is typically located below the center of the dash.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On the Verano, it’s found under the center of the dashboard. For other models, its location may vary (e.g., LH kick panel in the Cruze). Refer to a service manual for your specific vehicle.
- 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 the replacement BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- Reconnect Battery: Reattach the negative battery terminal.
- Test Functionality: Start the vehicle and test all body functions—lights, windows, locks, radio, etc.—to confirm the repair was successful.
Important Post-Installation Notes
In some cases, additional synchronization procedures may be needed. This is normal and depends on your vehicle’s specific configuration.
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration might be necessary to ensure proper brake light and traction control operation.
Disclaimer: Always consult a factory service manual or a qualified professional if you are unsure about any step.

Frequently Asked Questions
How does the cloning service work?
After you place your order, we will provide instructions for you to ship your original BCM to us. We then extract the vehicle-specific data and transfer it to the replacement module. We ship the programmed module back to you, ready for installation.
Will I need to program this BCM at the dealership?
No. Our cloning service makes this a plug-and-play solution. All necessary programming is done by us before we ship the part to you, saving you hundreds in dealership fees.
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer that controls many of your vehicle’s non-engine-related functions, such as power windows, locks, lights, security system, and wipers.
Is there a core charge?
No, there is no core charge for this part. You can keep your original module after sending it to us for the data transfer.
What if my airbag light comes on after installation?
This can happen occasionally. It requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by a mechanic with a professional-grade diagnostic tool to sync the airbag system.
