Is Your Chevy Volt Experiencing Strange Electrical Problems?
If your 2014-2015 Chevrolet Volt is plagued by flickering lights, malfunctioning power windows, a dead battery, or other bizarre electrical gremlins, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central nervous system for your vehicle’s body electronics, managing everything from the interior lights and door locks to the security system and power accessories. When it starts to fail, it can cause a cascade of frustrating and seemingly unrelated issues that can be difficult to diagnose.
From the Diagnostic Bay
We recently had a 2015 Volt towed in with a classic case of BCM failure. The owner reported that the car would randomly refuse to start, the radio would turn on and off by itself, and the interior lights would stay on, draining the battery overnight. After checking the battery and alternator, our diagnostics pointed directly to an internal fault in the BCM. Instead of a costly trip to the dealer for a new module and programming, we provided our cloning service. By transferring the original data to a replacement unit, we had the customer back on the road the next day with all electrical functions restored, saving them hundreds of dollars and significant downtime.
Symptoms of a Failing Body Control Module
A faulty BCM can manifest in numerous ways. If you’re noticing any of the following issues, it’s time to consider a replacement:
- ā Intermittent or non-functional power windows, locks, or mirrors.
- ā Interior or exterior lights that won’t turn on or off, or flicker erratically.
- ā The security system or keyless entry system malfunctioning.
- ā Unexplained battery drain that leaves you with a dead battery.
- ā Dashboard warning lights appearing without a clear cause.
- ā The radio or infotainment system behaving unpredictably.
- ā Horn honking randomly or not working at all.
The Simple, Plug-and-Play Solution: Our BCM Cloning Service
Don’t let a faulty BCM keep your Volt off the road. Dealerships will charge a premium for a new module and then add several hours of labor for programming. Our service is the smart, cost-effective alternative. We provide a fully functional, tested replacement BCM that is programmed with your vehicle’s exact data. This is achieved by cloning the information from your original, failing module.
The process is straightforward:
- Place Your Order: Complete your purchase on our website. Ensure your contact information is accurate.
- We’ll Contact You: Our team will reach out with simple instructions and a shipping address for you to send your original BCM to us.
- Send Us Your Original BCM: Carefully package and ship your module to our facility.
- We Clone & Ship Back: Once we receive your module, our technicians will professionally transfer all critical data to the replacement unit. We then ship the plug-and-play replacement back to you, typically within 24-48 hours, and provide you with tracking information.
This service ensures that the replacement BCM is a perfect match for your vehicle’s specific configuration, retaining all original keys and security settings. There is no need for an expensive trip to the dealership for additional programming.
Post-Installation Procedures for Your 2014-2015 Volt BCM
Our goal is a seamless installation. However, in some GM vehicles, certain systems may need to be re-synced after the BCM is replaced. These are simple procedures for any qualified technician with a professional scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, it means the new BCM needs to be synced with the vehicle’s SDM (Sensing and Diagnostic Module). A technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the light. This is only necessary if the light is on.
- Brake Pedal Position Relearn: To ensure proper brake light operation and stability control function, a brake pedal position sensor recalibration may be required. This is a quick procedure that ensures the BCM is reading the correct input from the brake pedal.
Please note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Is this BCM truly plug-and-play?
Yes. Because we clone the data from your original module, the replacement we send you will be ready to install without any additional dealer programming. It will recognize your existing keys and vehicle options.
Why do I need to send you my original BCM?
Your original BCM contains vital security information and vehicle-specific programming. By transferring this data directly to the replacement unit, we ensure a seamless, plug-and-play installation and avoid the high costs of dealership programming.
How long does the cloning service take?
We typically complete the programming and ship your replacement BCM within 24-48 hours of receiving your original module. Shipping times will vary based on your location.
What if the airbag light comes on after I install it?
This is a known possibility on some GM models. It simply means the BCM and the airbag module (SDM) need to be re-synced. A repair shop with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Do I have to pay a core charge?
No. There is no core charge for this service. You are welcome to keep your original, non-functional module.
