If you’re dealing with bizarre electrical issues in your 2014-2015 Chevrolet Volt, you’re not alone. As a technician with over two decades of experience, I’ve seen firsthand how a failing Body Control Module (BCM) can turn a reliable vehicle into a source of constant frustration. One minute the radio works, the next it doesn’t. The power windows have a mind of their own, and you’re seeing warning lights that make no sense. This isn’t just an inconvenience; it’s a sign that your car’s central nervous system for body electronics is failing.
The traditional fix involves a costly new module and an even more expensive trip to the dealership for programming. We offer a smarter, more affordable solution. This replacement BCM is prepared specifically for your vehicle using a professional data cloning service. You simply send us your original module, and we transfer all its critical data—including VIN, mileage, and key programming—to this replacement unit. The result? A true plug-and-play module that restores full functionality without any need for dealership intervention. It’s the most reliable way to get your Volt back to normal.
From the Diagnostic Bay: The Case of the Confused Volt
A customer brought in a 2015 Volt that was driving them crazy. The horn would honk randomly, the interior lights would flicker while driving, and the car sometimes refused to recognize the key fob. They had already been to two other shops that couldn’t pinpoint the problem. After running network diagnostics, I noticed communication dropouts pointing directly to the BCM. A failing BCM can send corrupt data across the vehicle’s network, causing other modules to act erratically. By providing a cloned 2014-2015 Volt BCM, we restored stable communication and resolved all the ghost-like electrical issues in a single afternoon, saving the customer from endless diagnostic fees.
Common Signs of BCM Failure in Your GM Vehicle
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, your Body Control Module is the likely culprit:
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ The security system acting up, or the vehicle not recognizing your key fob.
- ✔ Unpredictable behavior from the horn or windshield wipers.
- ✔ False warning lights on the instrument cluster (e.g., “Service Theft System”).
- ✔ Communication-related Diagnostic Trouble Codes (DTCs), such as U-codes (U0140, U0100).
Your Straightforward BCM Installation Guide
Installing your pre-programmed BCM is a manageable job for a confident DIYer. For the 2014-2015 Volt, the BCM is located in the right-hand (passenger side) of the engine compartment. Always consult a service manual for your specific vehicle’s procedure.
- Safety First: Disconnect the negative terminal from your vehicle’s 12V battery and secure it away from the post to prevent accidental reconnection.
- Locate the Module: On the Volt, find the BCM in the RH engine compartment. On other models, it may be under the dash or in a kick panel. Check your vehicle’s specific location from the fitment list below.
- Disconnect Connectors: Carefully release the locking tabs on each electrical connector and pull them straight out from the module. Do not force them.
- Remove the Old BCM: Unbolt the old BCM from its mounting bracket and remove it from the vehicle. This is the module you will ship to us for the cloning service.
- Install the New BCM: Once you receive the programmed module back from us, mount it securely in the original location.
- Reconnect Everything: Plug the electrical connectors firmly into the new BCM, ensuring they click into place. Reconnect the negative battery terminal.
- Perform Final Checks: Start the vehicle and test all body functions—lights, locks, windows, radio, etc.—to confirm the repair was successful.
Important Post-Installation Notes
While our cloning service makes this a plug-and-play repair, some vehicle systems may require a quick sync-up. If the airbag light is on, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. Additionally, some models may require a Brake Pedal Position Relearn for proper traction control and brake light operation. These are standard procedures after a BCM replacement.

Frequently Asked Questions
How does the programming service work?
After you place your order, we will contact you with instructions to ship your original BCM to us. Once we receive it, we perform a full data clone to the replacement unit and ship it back to you, typically within 1-2 business days. This process ensures all your vehicle’s specific settings are retained.
Do I need to take my car to a dealer after installation?
No. Our cloning service completely eliminates the need for dealership programming, saving you time and money. The module you receive will be plug-and-play for your specific vehicle.
What if my original BCM is completely dead or not communicating?
In most cases, even if the BCM has failed, the core data on the memory chip is still readable. We use specialized equipment to extract this data. If for some reason the data is unrecoverable, we will contact you to discuss options.
Is this a guaranteed fix for my car’s electrical problems?
This service corrects issues directly caused by a faulty BCM. While a failing BCM is a very common cause for the symptoms listed, proper vehicle diagnosis is always recommended to rule out other potential issues like wiring or sensor faults.
Do I have to send my old part back?
Yes, you must send us your original BCM for the data cloning service. However, there is no separate core charge, and you can keep your original module after we have completed the service if you wish.
