Restore Your Vehicle’s Electrical System with an Expert-Programmed BCM
If you’re dealing with baffling electrical issues in your 2014-2015 Chevrolet Volt—like flickering lights, malfunctioning power windows, or strange warning messages—a failing Body Control Module (BCM) is often the culprit. The BCM is the central computer for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating problems. Dealerships often charge a fortune for a new module plus expensive programming fees. We offer a smarter, more affordable solution.
This listing is for a fully tested, replacement BCM that comes programmed specifically for your vehicle. How do we do it? Through our professional cloning service. You simply send us your original BCM. Using specialized equipment, I personally transfer all the critical data—including the VIN, security keys, and specific options—from your module to this replacement unit. The result is a true plug-and-play component. Once you receive it back, you can install it without needing a trip to the dealer for programming. This service is the most reliable way to get a replacement 2014-2015 Volt BCM without introducing new software conflicts.
Case Study: A Tricky Diagnosis
A few months back, a 2015 Malibu came into the shop with a classic BCM failure symptom: the radio and interior lights would randomly turn off while driving. The owner had already replaced the battery and checked the main grounds. A scan showed a handful of U-codes, indicating a loss of communication between modules. Instead of just swapping the part, we connected a scope and saw a noisy data line originating from the BCM. By providing a cloned BCM, we not only fixed the immediate issue but also preserved all the vehicle’s original key fob programming and security settings, saving the customer hundreds in dealership fees and reprogramming headaches. This is the level of detail that ensures a lasting repair.
Common Signs of a Failing BCM
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, your BCM is the likely cause. Look out for Diagnostic Trouble Codes (DTCs) like U0140, U0155, or other communication-related faults.
- ✔ Power windows, locks, or mirrors not working or operating erratically.
- ✔ Interior or exterior lights (headlights, taillights) flickering, staying on, or not turning on at all.
- ✔ Vehicle security system acting up, causing no-start conditions or false alarms.
- ✔ Horn, windshield wipers, or other accessories failing to function correctly.
- ✔ Warning lights for ABS, Airbag, or Traction Control appearing on the dash.
- ✔ Inconsistent communication with diagnostic scan tools.
A Straightforward Guide to Installation
Installing your programmed 2014-2015 Volt BCM is a manageable job for a confident DIYer. For the 2014-2015 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 before starting any electrical work.
- Locate the BCM: On the Volt, find the BCM in the RH engine compartment. It’s a black box with several large electrical connectors.
- Disconnect and Remove: Carefully unplug all electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Seat the replacement BCM onto the mounting bracket and secure it. Reconnect all electrical connectors, ensuring they click firmly into place.
- Reconnect Battery: Reattach the negative battery terminal.
- Perform Post-Install Checks: Start the vehicle and test all body functions—lights, locks, windows, etc. Note that some vehicles may require additional relearn procedures as detailed below.
Important Post-Installation Information
While our cloning service makes this a plug-and-play process, some vehicle systems may need to be re-synced after the BCM is replaced. Please be aware of the following potential requirements:
- Airbag System Sync: If your airbag warning light is on 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 necessary for proper brake light and traction control operation.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
How does the programming service work?
After you purchase, we will contact you with instructions to ship your original BCM to us. Once we receive it, we transfer all the essential data to the replacement module and ship it back to you, typically within 1-2 business days.
Do I need to get this programmed by the dealer?
No. Our cloning service makes this a true plug-and-play solution. All the necessary programming from your original module is transferred, so you can avoid expensive dealer visits.
Is there a core charge for my old BCM?
No, there is no core charge. We need your original module to perform the data transfer, but you are welcome to have it shipped back to you with your newly programmed unit if you wish.
What if my airbag light comes on after installation?
This can happen occasionally. It means the airbag module (SDM) needs to be re-synced with the BCM. A procedure called ‘Setup SDM Primary Key in BCM’ will need to be performed with a professional-grade diagnostic tool to resolve it.
Which part number should I match?
This module, part number 13589115, is a direct replacement for a wide range of part numbers listed in the description. As long as your vehicle model and year are listed, this part will work with our programming service.
