Tired of Chasing Electrical Gremlins in Your GM Vehicle?
As a technician with over two decades of experience under the hood, I’ve seen it all. A customer comes in with a 2014 Chevy Volt, and the symptoms are all over the place: the radio cuts out, the power windows have a mind of their own, and a random assortment of warning lights are playing whack-a-mole on the dash. These aren’t separate problems; they’re often symptoms of one failing component: the Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s comfort and convenience features, and when it fails, it can be incredibly frustrating to diagnose. This is especially true for advanced vehicles like the Volt.
This isn’t just a replacement part; it’s a complete, hassle-free solution. We offer a professional programming service for this BCM, part number 13593775. You simply send us your original, faulty module. We then transfer all the critical, vehicle-specific data—including VIN, mileage, and key information—to this fully tested replacement unit. The result? A true plug-and-play module that eliminates the need for an expensive trip to the dealership for programming. You get your car back to normal without the headache.
A Technician’s Notebook
I remember a 2015 Cadillac ELR (which uses this same BCM family) that was a real head-scratcher. The owner complained of intermittent no-start conditions and a security light that would flash randomly. Other shops had replaced the battery and checked the ignition switch, but the problem persisted. When it got to my bay, I hooked up my professional scan tool and saw multiple ‘U’ codes, indicating a loss of communication between modules. Instead of just throwing parts at it, I went straight to the BCM. After confirming power and ground, it was clear the module itself was failing internally. By providing a cloned BCM, we had the car running perfectly in a day, saving the customer hundreds compared to the dealership’s quote for a new module and programming.
Common Signs of a Failing BCM
If your vehicle is experiencing any of the following, a faulty BCM could be the culprit. A failing 2014-2015 Volt BCM can create a wide range of confusing symptoms:
- âś” Power windows, door locks, or interior lights operating erratically or not at all.
- âś” The security system light is on, or the vehicle won’t start.
- âś” Horn, wipers, or radio functions are intermittent.
- âś” Multiple unrelated warning lights illuminated on the instrument cluster.
- âś” Diagnostic trouble codes (DTCs) related to communication errors, such as U0100, U0140, or other U-series codes.
- âś” Inconsistent operation of heating and A/C controls.
A Straightforward Guide to Installation
Our goal is to make this repair as simple as possible. The process is designed to get you a working part without needing special tools for programming.
- Place Your Order: Purchase this BCM programming service. We will then contact you with detailed instructions and the shipping address to send your original module to. Please ensure your contact information is correct.
- Remove Your Original BCM: On the 2014-2015 Volt, the BCM is located in the right-hand (passenger side) of the engine compartment. Carefully disconnect the negative battery terminal first. Then, unplug the electrical connectors and unbolt the module from its bracket.
- Ship Us Your Module: Securely package your original BCM and ship it to us. We recommend using a tracked shipping service.
- We Handle the Programming: Once we receive your module, our expert technicians will clone all the necessary data to the replacement unit within 1-2 business days.
- Install Your Plug-and-Play BCM: We will ship the newly programmed module back to you. Installation is the reverse of removal. Re-mount the BCM, plug in the connectors, and reconnect the battery. Your vehicle’s original settings and keys will work seamlessly.
Important Post-Installation Notes
In some cases, specific vehicle systems may require a recalibration after the BCM is installed. This is normal and ensures all related components communicate correctly with the new module.
- Airbag System Sync: If the airbag light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible professional scan tool. This syncs the airbag system with the BCM.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor relearn might be necessary.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Why is cloning my original BCM better than buying a used one?
Cloning transfers your car’s exact identity—the VIN, security key data, and specific options—to the replacement module. A used BCM from another vehicle will have incorrect data, leading to a no-start condition, warning lights, and features that don’t work. Our service avoids all of that.
Do I need to send my keys with the module?
No. Because we are transferring the data directly from your old module, the replacement unit will recognize your existing keys perfectly. You do not need to send your keys or have them reprogrammed.
Is there a core charge for this 2014-2015 Volt BCM?
No, there is no core charge. We use your original module for data extraction only. You are not required to return it after receiving the programmed replacement, but we do need it for the initial service.
What is the turnaround time for the programming service?
We pride ourselves on a fast and efficient service. Once we receive your original BCM, we typically complete the programming and ship your replacement module back out within 1-2 business days.
What if my original BCM is completely dead or not communicating?
In most cases, even if the BCM has failed, we can still extract the necessary data from the memory chip. If for some reason your module’s data is completely unrecoverable, we will contact you to discuss other options.
