Restore Your Volt’s Brain and End Electrical Frustrations
If your 2014-2015 Chevrolet Volt is experiencing bizarre electrical issues like flickering lights, malfunctioning power windows or locks, or random warning messages, a failing Body Control Module (BCM) is often the culprit. As the central nervous system for your vehicle’s body electronics, a faulty BCM can cause a cascade of frustrating and seemingly unrelated problems. This isn’t just an inconvenience; it can affect vehicle security and safety systems. We offer a reliable, straightforward solution that gets you back on the road without the exorbitant costs and scheduling headaches of a dealership visit.
Our service provides a replacement BCM that is professionally programmed with the data from your vehicle’s original module. This cloning process ensures that all your car’s specific configurations, security information, and VIN are perfectly matched. The result is a true plug-and-play component. Simply install it, and your Volt’s electronics will function as they should. This is the most efficient way to fix your 2014-2015 Volt BCM and restore peace of mind.
Case Study: A Tricky Diagnosis
A customer brought in a ’15 Volt with a complaint that was driving them crazy: the interior lights would randomly stay on, draining the battery overnight. They’d already replaced the battery twice. A quick scan showed a dozen communication codes (U-codes) pointing to network issues. In my 20+ years of experience, this pattern almost always leads back to the BCM. After confirming power and ground to the module were solid, we identified the internal BCM failure. By cloning his original module to one of our tested replacements, we solved the parasitic draw and all related communication faults in one shot. It’s a classic failure mode for these components.
Common Signs of a Failing BCM
A failing BCM can manifest in numerous ways. If your Volt is exhibiting any of these behaviors, it’s time to consider a replacement. Keep an eye out for Diagnostic Trouble Codes (DTCs) like U0140, U0155, or other communication-related faults.
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or failing to turn on.
- ✔ The security system acting up, or the key fob not being recognized.
- ✔ Horn sounding unexpectedly or not working when pressed.
- ✔ Dashboard warning lights appearing for seemingly no reason.
- ✔ Intermittent no-start conditions where the vehicle appears to be dead.
A Straightforward Guide to Installation
Our cloning service makes the physical replacement of your 2014-2015 Volt BCM a simple process. Since we handle all the programming, you won’t need any special scan tools for the initial setup.
- Safety First: Always disconnect the negative terminal from your vehicle’s 12V battery before starting any electrical work.
- Locate the BCM: On the 2014-2015 Volt, the Body Control Module is located in the right-hand (passenger side) of the engine compartment. Consult your service manual for a precise diagram if needed.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. Press the release tabs firmly to avoid damaging the clips. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Mount the replacement BCM you received from us into the same location. Reconnect all electrical connectors, ensuring they click securely into place.
- Reconnect Power: Reattach the negative battery terminal.
- Verify Functionality: Start the car and test all body functions—windows, locks, lights, horn, etc.—to confirm the repair was successful.
Important Post-Installation Information
In some cases, additional synchronization procedures may be needed after installation. This is normal and depends on your vehicle’s specific configuration.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is required. This must be done with a professional-grade diagnostic tool to sync the airbag system with the new BCM.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct operation of the brake lights and stability control systems.
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
How does the programming service work?
It’s simple. After you place your order, we will contact you with instructions to ship your original BCM to us. Once we receive it, we transfer all the critical data to the replacement module and ship it back to you, typically within 24-48 hours. This makes the new part plug-and-play.
Do I need to take my car to a dealer after installation?
No! Our cloning service completely eliminates the need for dealership programming. The module arrives ready to install and function. The only exception is the potential need for an airbag or brake sensor relearn, which can be done by most independent shops if required.
Is there a core charge for my old BCM?
There is absolutely no core charge. You can keep your original module. Our price includes the replacement BCM and the programming service.
What information do you need from me?
After your purchase, we will contact you to arrange the shipping of your original module. Please ensure your contact information (phone number and email) is correct in your order so we can reach you promptly.
What if my original BCM is completely dead or not communicating?
In most cases, even if the BCM has failed, we can still extract the necessary data for cloning. If you suspect your module is severely damaged (e.g., by water or fire), please contact us before ordering to discuss the situation.
