Tired of Electrical Gremlins in Your GM Vehicle?
Is your 2013 Chevrolet Volt or another compatible GM model acting possessed? Flickering lights, unresponsive power windows, random warning chimes, or a car that refuses to start can all point to one culprit: a failing Body Control Module (BCM). As the central nervous system for your vehicle’s electronics, when the BCM goes bad, it can create a cascade of frustrating and unpredictable problems. I’ve seen it hundreds of times in my shop—what seems like a dozen different issues is often just this single, vital component giving up.
This isn’t just a replacement part; it’s a complete, hassle-free solution. We offer a professionally programmed BCM that eliminates the need for expensive dealership visits and complex programming tools. Our unique cloning service makes this a true plug-and-play fix for your vehicle.
A Technician’s Notebook: The Case of the Intermittent Volt
A customer brought in a 2013 Volt with a list of complaints that seemed unrelated. The radio would cut out, the driver’s side window would sometimes not respond, and occasionally the dome light would stay on after the door was closed. They’d been to two other shops that couldn’t find the issue because it was so intermittent. After connecting my scan tool, I noticed several ‘Lost Communication’ codes (U-codes) with various modules. This is a classic sign. Instead of a wiring problem, the BCM itself was failing internally, corrupting the data network. By swapping in a known-good BCM, all the phantom issues vanished. This is why a reliable 2013 Volt BCM is critical for restoring proper function.
Common Signs of a Failing BCM
If you’re experiencing any of the following, a faulty BCM is the likely cause. A scan tool might show communication codes like U0140, U0155, or other B-series (Body) codes.
- ✔ Erratic or non-functional power windows, locks, and mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ The security system acting up, causing no-start conditions.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Inconsistent instrument cluster operation or warning lights.
- ✔ Wipers activating on their own or not responding to the switch.
Our Simple Plug-and-Play Installation Guide
Our cloning service makes replacing your 2013 Volt BCM straightforward. Once you receive the programmed module from us, follow these general steps:
- Step 1: Safety First. Always disconnect the negative terminal from your vehicle’s 12V battery before working on any electronic components.
- Step 2: Locate Your BCM. On the 2013 Volt, the BCM is typically found in the right-hand (passenger side) of the engine compartment. For other models, it may be under the dash or in a kick panel. Consult a service manual for your specific vehicle if unsure.
- Step 3: Remove the Old Module. Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Step 4: Install the New Module. Seat the new, programmed BCM into the mounting bracket and securely plug in all the electrical connectors. You should hear a click as they lock into place.
- Step 5: Reconnect and Test. Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—lights, locks, windows, wipers, etc.—to confirm the repair.
Important Post-Installation Notes
While our programming makes this a direct-fit solution, some vehicle systems may require a quick sync-up. An Airbag System Sync might be needed if the airbag light is on. This ‘Setup SDM Primary Key in BCM’ procedure requires a professional scan tool. Additionally, a Brake Pedal Position Relearn may be necessary on some models to ensure proper brake light and traction control operation. As always, consult a factory service manual for vehicle-specific details.

Frequently Asked Questions
How does the programming service work?
It’s simple! After you place your order, we’ll provide instructions for shipping your original BCM to us. Once we receive it, our technicians will clone all the critical data (like VIN, mileage, and key information) to the replacement unit. We then ship the plug-and-play module back to you.
Do I need to send my keys?
No, you do not need to send us your keys. Our cloning process transfers all the necessary security information from your original module, so your existing keys will work perfectly with the new BCM.
Is this a guaranteed fix for my car’s electrical problems?
This part will fix any issues directly caused by a faulty BCM. If you’ve diagnosed the BCM as the source of the problem, our programmed module is the most reliable and straightforward solution available.
What is the turnaround time?
We pride ourselves on a fast turnaround. We typically program and ship the replacement module within 1-2 business days of receiving your original unit. You will receive a tracking number as soon as it ships.
Do I have to pay a core charge?
No, there is absolutely no core charge for this part. You can keep your original module after you send it to us for the data cloning service.
