Is Your Chevrolet Volt Experiencing Bizarre Electrical Problems?
The Body Control Module (BCM) is the central command center for your vehicle’s body electronics. It manages everything from your power windows and door locks to the interior lights, security system, and even communicates with other critical modules. When the BCM starts to fail, it can create a cascade of frustrating and seemingly unrelated issues, turning your reliable Volt into a source of constant headaches. If you’re dealing with flickering lights, malfunctioning accessories, or random warning messages, a faulty BCM is the likely culprit.
From the Diagnostic Bay
We had a 2015 Volt come into the shop with a list of complaints that sounded like a poltergeist had taken over. The dome light would stay on, the driver’s side window wouldn’t roll down, and the car would randomly honk its horn when locked. The owner had already replaced the battery and checked all the fuses. After connecting our diagnostic tool, we saw multiple communication errors all pointing back to one source. The BCM was failing internally, sending corrupt data across the vehicle’s network. Instead of a costly trip to the dealer for a new module and programming, we used our cloning service. We transferred the data from his old, faulty BCM to our replacement unit. He was back on the road the next day with all issues resolvedāno expensive dealership programming, no lengthy wait times.
Symptoms of a Failing Body Control Module
A failing BCM can manifest in numerous ways. Pay close attention if your vehicle is exhibiting any of the following symptoms, as they are strong indicators that your module needs attention:
- ā Intermittent or non-functional power windows, door locks, or mirrors.
- ā Interior or exterior lights that flicker, stay on, or don’t work at all.
- ā The anti-theft or security system engaging randomly or preventing the car from starting.
- ā Inaccurate gauge readings on the instrument cluster.
- ā Key fob not working correctly for locking, unlocking, or remote start.
- ā Warning lights appearing on the dash with no apparent cause.
- ā Complete loss of power to various electronic accessories.
The Simple, Plug-and-Play Solution: Our BCM Cloning Service
Don’t let a dealership charge you a fortune for a new module and the hours of labor required to program it. Our professional cloning service is the most efficient and cost-effective way to get your car back to normal. We take all the critical, vehicle-specific informationālike the VIN, key data, and security settingsāfrom your original BCM and flash it directly onto this replacement unit. The result is a true plug-and-play module. Once you receive it, the installation is as simple as swapping the old part for the new one. No additional programming or calibration is required.
How The Process Works:
- ā Place Your Order: Complete your purchase through our secure checkout.
- ā We’ll Contact You: We will reach out to you with clear, simple instructions on how to ship your original BCM to our facility. Please ensure your contact information is up to date.
- ā We Perform the Service: Once we receive your module, our technicians will perform a full data transfer to the replacement 2014-2015 Volt Body Control Module.
- ā Receive Your Ready-to-Install Part: We ship the programmed module back to you, typically within 24-48 hours of receiving your original. We will provide you with tracking information so you know exactly when it will arrive.
Important Post-Installation Information
While our goal is a 100% plug-and-play experience, certain vehicle systems may require a quick sync-up procedure after the new BCM is installed. These are not programming steps but rather relearn procedures that can sometimes be necessary.
- Airbag System Sync: If the airbag warning light is illuminated after installation, it means the new BCM needs to be synchronized with the vehicle’s SDM (Sensing and Diagnostic Module). A professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is only required if the light is on.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be needed to ensure proper operation of the brake lights and stability control systems.
Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.

Frequently Asked Questions
What exactly is a Body Control Module (BCM)?
The BCM is a computer in your car that controls and monitors most of the non-engine related electronic functions. This includes power windows, locks, lights, wipers, the security system, and more. It acts as a central hub for these systems.
How does this programming service work?
After you place your order, you will ship your original BCM to us. We use specialized equipment to extract the unique data from your module and transfer it to the replacement unit. This ‘cloning’ process ensures the replacement BCM is a perfect match for your vehicle’s configuration.
Will I need a mechanic to install this part?
Because the module comes pre-programmed, the installation is a direct swap. It is physically straightforward for someone with basic mechanical skills. However, if you are not comfortable working on your vehicle, we always recommend professional installation.
Why can’t I just buy a used BCM from a junkyard?
A used BCM from another vehicle is programmed with that vehicle’s specific VIN and security information. It will not work in your car without being reprogrammed by a dealership or a specialized service like ours, which can be very expensive and time-consuming. Our service eliminates that step.
What happens if the airbag light comes on after I install it?
This is a rare but possible occurrence. It means the BCM and the airbag module (SDM) need to be re-synchronized. A technician with a professional diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
