End the Electrical Gremlins in Your Chevy Volt
If you’re dealing with bizarre electrical issues in your 2014-2015 Chevy Volt—like power windows with a mind of their own, flickering interior lights, a security system that won’t cooperate, or intermittent no-start conditions—you’ve likely met the culprit: a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can cause widespread, frustrating problems. In my 20+ years as a technician, I’ve seen how a single failing module can make a perfectly good car feel unreliable. That’s why we offer a definitive, hassle-free solution.
This isn’t just a replacement part; it’s a complete plug-and-play service. You send us your original BCM, and we transfer all its critical data—including key programming, security settings, and vehicle-specific options—to this fully tested replacement unit. The result? A module that is 100% ready for installation, with no need for an expensive trip to the dealership for programming. This service is the most reliable way to replace your 2014-2015 Volt BCM and restore your car’s proper function.
From the Diagnostic Bay: The Case of the Phantom Drain
A customer brought in a 2015 Volt with a classic complaint: the 12V battery was dead every morning. They’d already replaced the battery twice. We tested the alternator and starter, which were fine. The real work began with a parasitic draw test. We found a significant draw coming from an interior lighting circuit, but all the lights were off. After isolating circuits one by one, we traced the issue to the BCM. Internally, it was keeping the CAN bus network ‘awake’ long after the car was shut off, slowly draining the battery. Swapping in a cloned BCM like this one solved the problem instantly. It’s a perfect example of how BCM faults can be subtle yet deeply problematic.
Is Your Volt Exhibiting These BCM Failure Signs?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, your BCM is the likely cause:
- ✔ Power windows, locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights staying on, flickering, or not turning on.
- ✔ The anti-theft or security system light is on, preventing the car from starting.
- ✔ Inconsistent or non-functional remote keyless entry.
- ✔ Dashboard warning lights appearing randomly (e.g., ABS, Airbag, Traction Control).
- ✔ Communication error codes stored, such as U0140 (Lost Communication With Body Control Module).
Your Straightforward BCM Installation Guide
Installing your pre-programmed BCM is designed to be a direct process. 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 diagrams and torque specs.
- Safety First: Disconnect the negative terminal from your 12V battery and secure it away from the post to prevent accidental reconnection.
- Locate the BCM: Open the hood and find the BCM in the RH engine compartment. You may need to remove a cover or other components for access.
- Disconnect Wiring: Carefully release the locking tabs on each electrical connector and pull them straight out from the module. Never pull on the wires themselves. Take a photo beforehand for easy reference.
- Remove the Old Module: Unbolt the mounting fasteners holding the original BCM in place and remove it from the vehicle.
- Install the New Module: Mount your new, programmed BCM in the same location, securing it with the original fasteners.
- Reconnect Everything: Plug the electrical connectors firmly back into the new BCM, ensuring they click into place. Reconnect the negative battery terminal.
Important Post-Installation Steps
While our cloning service makes this a plug-and-play repair, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated 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 may be required to ensure correct brake light operation and to clear any traction control faults.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a qualified technician for specific procedures.

Frequently Asked Questions
How does the cloning 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 transfer the essential data to the replacement module and ship it back to you, typically within 1-2 business days.
Is this truly plug-and-play?
Yes. Because we clone your original module’s data, the replacement BCM will not require any additional programming from a dealer. It arrives ready to be installed and used.
Do I need to send my keys with the module?
No, you do not need to send your keys. All the necessary security information is stored within the BCM itself, and we transfer that data directly.
What if my original BCM is completely dead or not communicating?
In many cases, we can still extract the necessary data even from a non-communicating module. Please contact us with your specific situation before ordering if your module is severely damaged (e.g., by water or fire).
Do I have to return my old BCM after installation?
No. There is no core charge for this service. You only need to send us your original BCM for the data transfer service. You can keep it afterward.
Will this fix my specific problem?
This service corrects issues caused by a faulty BCM. While the symptoms listed are common indicators, proper vehicle diagnosis is essential. We recommend confirming the BCM is the source of the fault before ordering.
