Restore Full Functionality to Your Vehicle with a Plug-and-Play BCM
Are you dealing with baffling electrical issues in your Cadillac, Buick, or Chevy? Flickering lights, power windows with a mind of their own, or random warning messages on the dash are classic signs of a failing Body Control Module (BCM). As the central computer for your vehicle’s comfort and convenience features, a faulty BCM can make driving a frustrating experience. This isn’t just an inconvenience; it can affect security systems and lighting, creating a safety concern. This is a direct-fit solution for your 2014-2016 ELR Body Control Module and other compatible GM vehicles.
We offer a straightforward and reliable fix. Instead of paying for expensive dealership programming and diagnostics, our service transfers all the critical data from your original BCM to this replacement unit. This cloning process ensures that your vehicle accepts the new module without any complex relearning procedures. It retains your vehicle’s specific settings, key fob information, and mileage, making the installation process as simple as swapping the part.
A Technician’s Notebook: The Case of the Haunted LaCrosse
A few months back, a 2015 Buick LaCrosse came into the shop with a list of problems that sounded like something out of a ghost story. The interior lights would fade in and out while driving, the radio would randomly change stations, and the key fob worked only intermittently. The owner had already been to two other shops that couldn’t find the issue. After hooking up the scan tool, I saw a handful of U-codes (communication errors) pointing to the BCM. Instead of a costly new module and hours of programming, we used this exact cloning service. The customer shipped us their faulty BCM, we transferred the data, and sent the replacement back. They installed it in under 30 minutes, and every single electrical gremlin was gone. It’s a testament to how effective this solution is for complex BCM failures.
Common Signs of a Failing BCM
If you’re experiencing any of the following, a failing BCM is the likely culprit. Replacing it can restore your vehicle’s proper operation and your peace of mind.
- ā Erratic or non-functional power windows, door locks, or mirrors.
- ā Interior dome lights or exterior lamps staying on or not working at all.
- ā The security system or alarm malfunctioning or engaging randomly.
- ā Key fobs that stop working or function intermittently.
- ā False warning lights appearing on the instrument cluster.
- ā Diagnostic Trouble Codes (DTCs) related to communication errors, such as U0140, U0155, or other U-series codes.
A Straightforward Guide to Installation
Our cloning service makes this a simple component swap. After you receive the programmed module from us, follow these general steps. The BCM in the 2014-2016 ELR is located on the right-hand side of the cowl.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: Access the Body Control Module. Its location varies by model (see fitment list), but it’s typically behind a kick panel or under the dash.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. Then, unbolt or unclip the module from its mounting bracket and remove it.
- Install the New Module: Mount the replacement BCM in the same location and securely reconnect all electrical harnesses.
- Reconnect Power: Reattach the negative battery terminal. Start the vehicle and test all functions like lights, windows, and locks to confirm the repair.
Important Post-Installation Information
While our service eliminates the need for programming, some vehicle systems may require a simple sync procedure after the BCM is replaced.
- 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 BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure brake lights and stability control systems function correctly.
Disclaimer: Vehicle systems vary. Always consult a factory service manual or a qualified technician if you are unsure about any step.

Frequently Asked Questions
How does the programming service work?
After you place your order, we will provide you with instructions to ship your original BCM to us. Once we receive it, our technicians will transfer the essential vehicle data to the replacement module. We then ship the ready-to-install part back to you. This service means no extra programming is needed on your end.
Do I need to take my car to the dealer after installation?
No. Our cloning service makes this a plug-and-play solution. Your vehicle’s keys and security information are transferred, so you can avoid a costly trip to the dealership for programming.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM seems dead, we can still extract the necessary data. Please contact us before ordering if your module is severely damaged by water or fire, or if it has no communication whatsoever with a professional scan tool.
How long does the entire process take?
We typically program and ship your replacement module within 24-48 hours of receiving your original BCM. The total time will depend on shipping times to and from our facility.
Do I need to send back my old part after installation?
No, there is no core charge for this item. You can keep your original module.
