Are you battling frustrating electrical problems in your 2014-2015 Chevrolet Volt? When the Body Control Module (BCM) starts to fail, it can feel like your car has a mind of its own. As the central hub for your vehicle’s body electronics, a faulty BCM can cause a cascade of confusing issues. From my 20+ years in automotive diagnostics, I’ve seen these modules cause everything from minor annoyances to complete no-start situations. This isn’t just a part; it’s the solution to getting your Volt’s complex systems communicating correctly again.
We offer a straightforward and reliable fix. Instead of buying a blank module that requires expensive and complicated programming at a dealership, you send us your original BCM. We then transfer—or ‘clone’—all the critical vehicle-specific data, including the VIN and security information, to this fully tested replacement unit. The result? A true plug-and-play module arrives at your door, ready for installation. This service for your 2014-2015 Volt BCM bypasses the need for specialized scan tools for programming, saving you significant time, money, and hassle.
A Technician’s Notebook: The Ghost in the Machine
A customer brought in a 2015 Chevy Malibu (which uses this same family of BCMs) with a truly bizarre problem. The radio would turn on by itself, the driver’s side window would randomly roll down, and the anti-theft light would flash intermittently. They had already replaced the battery and checked all the fuses. After connecting my diagnostic tool, I saw a slew of ‘Lost Communication’ codes (U-codes) pointing to the BCM. Instead of a hard failure, the module was sending corrupt data packets across the CAN bus network, creating these ‘ghost’ commands. By cloning his original BCM data to a solid replacement unit, we resolved every single issue in one shot. It’s a classic case where only a data-matched BCM could provide a permanent fix.
Common Signs of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, or interior lights.
- ✔ The security system light stays on or flashes, potentially causing a no-start condition.
- ✔ Horn, wipers, or turn signals activating on their own or not working at all.
- ✔ Multiple warning lights on the dashboard with no clear cause.
- ✔ Diagnostic trouble codes (DTCs) related to lost communication, such as U0140, U0155, or other U-codes.
- ✔ Inconsistent key fob or remote start operation.
Your Straightforward Mail-In and Installation Guide
- ✔ Place Your Order: After purchasing, we will contact you with detailed instructions and a shipping address. Please ensure your contact information is accurate.
- ✔ Ship Your Original BCM: Carefully package and ship your vehicle’s original Body Control Module to us. For the 2014-2015 Volt, the BCM is typically located in the right-hand (passenger side) of the engine compartment.
- ✔ Cloning Process: Once we receive your module, our technicians will perform a full data transfer to the replacement unit. This process usually takes 1-2 business days.
- ✔ Post-Installation Checks: Start the vehicle and verify that all body functions (lights, windows, locks) are working correctly. Refer to the ‘Important Technical Notes’ section below for potential follow-up steps.
Important Technical Notes After Installation
While our cloning service makes this a plug-and-play solution, some GM vehicles may require minor system recalibrations. These are not programming steps but rather system ‘handshakes’.
- Airbag System Sync: If your airbag warning light is on after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure may be needed. This is a common security handshake between modules and can be performed with a professional-grade diagnostic tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be necessary to ensure perfect brake light and traction control operation.
- No Core Charge: You are not required to return your original module to us after the service. The price you pay is final, with no hidden core fees.
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 cloning service work?
You ship your original BCM to us. We use specialized equipment to read the unique, vehicle-specific software and security data from your module and write it directly onto the replacement unit. This ensures the new module is an exact digital copy of your old one, making it ready to install without any additional programming.
Why is this better than buying a used BCM from a junkyard?
A used BCM from another vehicle is locked to that car’s VIN and options. It will not work correctly in your car and will likely cause a no-start condition or other major faults. Our cloning service ensures the replacement BCM is perfectly matched to your specific vehicle.
How long does the entire process take?
Once we receive your module, the cloning and testing process typically takes 1-2 business days. The total time will depend on shipping times to and from our facility. We will provide you with a return tracking number as soon as it ships.
What if my original BCM is too damaged to be read?
This is a rare occurrence, but if your module has suffered severe water or fire damage, the data may be unrecoverable. In such cases, we will contact you to discuss alternative options or provide a full refund for the service.
Do I need special tools to install the new 2014-2015 Volt BCM?
No. The physical installation typically only requires basic hand tools to access and unbolt the module. Our cloning service eliminates the need for expensive dealer-level diagnostic computers for programming, making it a DIY-friendly solution.
