Tired of Unpredictable Electrical Problems in Your GM Vehicle?
As a technician with over two decades of experience, I’ve seen firsthand how a failing Body Control Module (BCM) can turn a reliable car into a source of daily frustration. One day the power windows refuse to work, the next the security light is flashing, and sometimes, the car won’t even start. The BCM is the nerve center for your vehicle’s comfort and convenience features, and when it fails, it can cause a cascade of baffling symptoms. If you’re dealing with these issues in your 2013 Chevrolet Volt or another compatible GM model, you’ve found the right solution.
This isn’t just a replacement part; it’s a comprehensive programming service. We eliminate the biggest hurdle of BCM replacement: the expensive and complex programming required at a dealership. By sending us your original module, you allow our experts to perform a direct data transfer to this fully tested replacement unit. We clone all the essential information—including key fob programming, VIN, and vehicle-specific options. The result? You receive a true plug-and-play 2013 Volt BCM that restores function without the dealership headache.
From the Diagnostic Bay: The Phantom No-Start
A customer brought in a 2013 Chevy Cruze that would intermittently fail to start. No crank, no click—just silence. The battery was new, the starter tested fine, and there were no engine codes. After hours of chasing wires, we noticed the security light would sometimes flicker when the no-start occurred. This pointed us toward the BCM. A failing BCM can disrupt the anti-theft system’s communication with the key, preventing it from authorizing the engine to start. We performed our cloning service, the customer installed the new BCM in their driveway, and the phantom no-start problem was solved for good. It’s a classic example of how the BCM’s health is critical for more than just the windows and locks.
Common Signs of a Failing GM Body Control Module
- ✔ Erratic or non-functional power windows, door locks, and interior lights.
- ✔ The security or anti-theft light stays on or flashes, potentially causing a no-start condition.
- ✔ Key fobs or remote entry stop working suddenly.
- ✔ Horn honking randomly or the alarm going off without reason.
- ✔ Communication error codes, often in the U-series (e.g., U0140 – Lost Communication With Body Control Module).
- ✔ Headlights or tail lights staying on and draining the battery, or not turning on at all.
Your Straightforward BCM Installation Guide
Our cloning service handles the complicated software side. Your job is the simple mechanical swap. Here’s a general guide:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on electrical components.
- Locate Your BCM: The location varies by model (see fitment list). Common spots for this 2013 Volt BCM and its sister parts are behind the driver’s side kick panel, under the dash, or in the engine compartment.
- Disconnect and Remove: Carefully unplug the wiring harness connectors. They have locking tabs that need to be pressed. Once disconnected, unbolt or unclip the old module from its mounting bracket.
- Install the New Module: Seat the replacement module in the mounting bracket and securely plug in all wiring harnesses. You should hear a click as they lock into place.
- Reconnect Power: Reattach the negative battery terminal.
- Test Functions: Start the vehicle and test all body functions—windows, locks, lights, wipers, and radio—to confirm the repair.
Post-Installation Notes
In most cases, this module is ready to go. However, on some vehicles, additional steps may be needed:
- 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 is only required if the light appears.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper brake light and traction control operation.
We stand by our work, but always recommend consulting a factory service manual for procedures specific to your exact vehicle.

Frequently Asked Questions
How does this programming service work?
It’s simple. After you purchase, we will contact you with instructions to ship your original BCM to us. Once we receive it, we transfer all of its critical data to the replacement module. We then ship the plug-and-play module back to you.
Do I need to send my keys or any other parts?
No. Because we are cloning the data directly from your original BCM, all of your existing keys and key fobs will work seamlessly with the replacement module. You only need to send us the BCM itself.
Is this a guaranteed fix for my problem?
This service corrects issues caused by a faulty BCM. While the symptoms listed are common indicators, we always recommend a proper diagnosis by a qualified mechanic to confirm the BCM is the root cause of your vehicle’s problems before ordering.
What is the turnaround time?
We perform the cloning service and ship the replacement module back to you promptly upon receiving your original unit. You will receive a tracking number as soon as it ships.
Is there a core charge?
No, there is absolutely no core charge. You can keep your original module once our service is complete.
What tools do I need for the installation?
For most vehicles, only basic hand tools are required, such as a socket set or screwdriver to access and remove the module. No special programming tools are needed thanks to our cloning service.
