Restore Your Vehicle’s Electrical System with a Hassle-Free Solution
Are you dealing with baffling electrical issues in your 2014-2015 Chevrolet Volt? Flickering lights, malfunctioning power windows or locks, or strange warning messages on the dash are classic signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your car’s comfort and convenience features. When it fails, it can make your vehicle frustrating to operate. Dealerships often charge a fortune for a new module plus expensive programming fees. We offer a smarter, more affordable path forward.
This is a fully tested, replacement BCM that comes ready for installation through our convenient mail-in programming service. You simply purchase this module, ship your original BCM to us, and we handle the rest. We’ll professionally transfer all the critical vehicle-specific data from your original module to this replacement unit. The result? A BCM that is truly plug-and-play, saving you from the time, cost, and complexity of dealership intervention. We will contact you with shipping instructions for your original module right after you place your order.
From the Diagnostic Bay
I recently had a 2015 Volt in the shop with a laundry list of complaints from the owner: the radio would randomly turn off, the passenger window wouldn’t work, and the security light was always on. After checking all the fuses and wiring, my diagnostic scanner kept showing communication loss with multiple systems (U-codes). This pointed directly to the BCM. Instead of a costly new unit, we used our cloning service. Once the programmed replacement arrived, it was a 20-minute install. Every single issue was resolved instantly. This service is a game-changer for both DIYers and professional shops.
Common Signs of a Failing BCM
If your vehicle is experiencing any of the following, a faulty Body Control Module could be the culprit:
- ✔ Erratic or non-functional interior/exterior lights
- ✔ Power windows, door locks, or mirrors working intermittently or not at all
- ✔ The security system or keyless entry failing to operate correctly
- ✔ Unexplained battery drain when the vehicle is off
- ✔ Multiple communication error codes (U-codes) stored in the system
- ✔ Inaccurate gauge readings or warning lights on the instrument cluster
Your Straightforward BCM Installation Guide
Installing your pre-programmed BCM is a manageable job for a confident DIYer. For the 2014-2015 Chevrolet Volt, the BCM is located in the right-hand (passenger side) of the engine compartment.
- Safety First: Always disconnect the negative terminal from your vehicle’s 12V battery and wait a few minutes to ensure all systems are powered down.
- Locate the BCM: On your Volt, find the BCM in the passenger-side area of the engine bay. It’s a black box with multiple large electrical connectors.
- Disconnect and Remove: Carefully release the locking tabs on each electrical connector and pull them straight out. Then, unbolt the module from its mounting bracket.
- Install the New Module: Seat the new, programmed BCM onto the mounting bracket and secure it. Firmly reconnect all electrical connectors, ensuring they click into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test all body functions—lights, locks, windows, etc.—to confirm proper operation.
Important Post-Installation Information
While our programming service makes this a plug-and-play part, some vehicle systems may require a quick sync-up after installation:
- 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 might be required to ensure your brake lights and traction control system function as intended.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual or consult a qualified technician if you are unsure about any step.

Frequently Asked Questions
How does the mail-in programming service work?
It’s simple. After you purchase, we will contact you with instructions to ship your original BCM to our facility. Once we receive it, we transfer its unique data to your replacement module and ship it back to you, typically within 1-2 business days. This makes it ready to install right out of the box.
Is this a difficult part to install myself?
For someone with basic mechanical skills, this is a very straightforward installation. The BCM is usually easy to access, and since we’ve pre-programmed it, no special computer tools are needed for the initial setup. Just follow our guide and take your time.
What if my airbag light comes on after I install it?
This can happen occasionally. It means the BCM and the airbag module (SDM) need to be re-synced. This is a simple procedure called ‘Setup SDM Primary Key in BCM’ that can be done by any repair shop with a professional-grade diagnostic tool.
Do I need to send my keys with my old module?
No, we do not need your keys. All the necessary security and vehicle information is contained within the BCM itself, which is what we transfer during our programming process.
Is there a core charge for this part?
No, there is no core charge. You can keep your original, non-working module after you send it to us for the data transfer.
