Restore Your Vehicle’s Brain without the Dealership Headache
If you’re dealing with bizarre electrical issues in your 2015 Corvette or another compatible GM vehicle—like power windows with a mind of their own, flickering interior lights, or a car that refuses to start—you’ve likely met the frustrating reality of a failing Body Control Module (BCM). As the central nervous system for your vehicle’s comfort and convenience features, a faulty BCM can turn your daily drive into a nightmare. I’ve seen it hundreds of times in my shop: a customer comes in, exasperated after chasing electrical gremlins for weeks, only to find the BCM is the culprit.
The typical solution involves a costly new module from the dealership, followed by several hours of expensive programming. We offer a smarter, more efficient fix. This is a fully tested, replacement BCM that comes ready for installation through our professional cloning service. You simply send us your original BCM, and we transfer all of its vital data—including key programming and vehicle-specific settings—to this replacement unit. The result? A true plug-and-play solution that gets you back on the road fast, saving you time and money.
A Technician’s Notebook: The Case of the Haunted Sierra
A few months back, a 2015 Sierra 1500 was towed to my bay. The owner said the radio would randomly switch stations, the dome light would stay on, and occasionally, the truck wouldn’t recognize the key fob. He’d already replaced the battery and checked all the fuses. After connecting my scan tool, I saw a flurry of U-codes (communication errors) pointing to the BCM. Instead of a new, unprogrammed unit, we used our cloning service. We transferred the data from his failing BCM to a replacement. He plugged it in himself that afternoon, and every single issue was resolved. It’s a powerful fix for what seems like a complex ghost in the machine.
Common Signs of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and interior/exterior lights.
- ✔ The security system acting up, preventing the vehicle from starting (anti-theft light on).
- ✔ Dash warning lights appearing randomly, such as for the airbag or traction control system.
- ✔ Intermittent failure of the radio, climate controls, or instrument cluster gauges.
- ✔ Communication-related Diagnostic Trouble Codes (DTCs) like U0140, U0155, or B1001.
- ✔ Complete no-start condition where the starter doesn’t even click.
Our Simple Plug-and-Play Installation Process
- ✔ Step 2: We Handle the Programming. Once we receive your module, our technicians will perform a full data transfer to the replacement BCM. This cloning process ensures all your vehicle’s original settings are perfectly preserved.
- ✔ Step 3: Install Your Ready-to-Go Module. We ship the programmed BCM back to you. Simply disconnect your negative battery terminal, locate and remove your old BCM, and install the new one. Reconnect the battery, and you’re done. No dealership visit required!
Important Post-Installation Checks
While our cloning service makes this a straightforward swap, some vehicle systems may require a quick handshake with the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the modules.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light and stability control operation.
Disclaimer: We always recommend consulting a factory service manual or a qualified technician for vehicle-specific procedures. No core charge is required; you can keep your original module.

Frequently Asked Questions
Do I need to program this BCM?
No. This BCM is sold as part of a cloning service. We transfer the programming from your original module to this replacement, making it plug-and-play when you receive it.
How does the cloning service work?
After your purchase, we will provide you with an address and instructions to ship your original BCM to us. Once we receive it, we copy the data and ship your new, programmed BCM back to you, typically within 1-2 business days.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is failing, the core data on the memory chip is still readable. Please contact us before ordering if your BCM is unresponsive so we can determine if a successful clone is possible.
Is this a guaranteed fix for my car’s electrical problems?
A failing BCM causes very specific symptoms. While this part will fix issues directly caused by the BCM, it’s essential to properly diagnose your vehicle. This module will not fix problems related to wiring, sensors, or other modules.
What tools do I need for installation?
Typically, you’ll only need basic hand tools like a socket set and trim removal tools to access the BCM. The location varies by model (e.g., under the dash, behind a kick panel), so a service manual can be helpful. No programming tools are required.
