Restore Your Vehicle’s Electronic Functions with a Hassle-Free Solution
If you’re dealing with bizarre electrical problems in your 2015 Corvette or another compatible GM vehicle—like power windows with a mind of their own, flickering lights, a security system that won’t cooperate, or even a no-start condition—a failing Body Control Module (BCM) is often the culprit. As the central command for your car’s body electronics, a faulty BCM can cause widespread chaos. Dealerships will quote you a fortune for a new module plus hours of labor for programming. We offer a smarter, simpler, and more affordable path forward.
This is not just a replacement part; it’s a complete, plug-and-play solution. Our service involves cloning the essential data from your original BCM directly onto this fully tested replacement unit. This means all the specific settings for your vehicle’s VIN, options, and security keys are perfectly preserved. When you receive the module back from us, it’s ready for immediate installation without any need for expensive dealer tools or programming. You get a reliable fix that restores your car’s functionality quickly and efficiently.
From the Diagnostic Bay: The Case of the C7’s Electrical Chaos
A few months back, a 2015 Corvette C7 rolled into my shop with a list of symptoms that sounded like a poltergeist had taken up residence. The radio would randomly shut off, the driver’s side window wouldn’t drop for the door to open properly, and the dash lights would occasionally flicker for no reason. The owner was frustrated, having already replaced the battery with no luck. After connecting my scan tool, I saw a flurry of communication errors, all pointing back to a single source: the BCM. Instead of a costly new module and a full reprogramming from scratch, we opted for a cloned unit. We sent the original BCM out, got the programmed replacement back in a couple of days, and installed it in under 30 minutes. Every single electrical gremlin was gone. The car was back to its perfect, high-performance self, and the owner saved hundreds compared to the dealer’s quote. This is the power of a properly cloned module.
Is Your GM Vehicle Showing These BCM Failure Signs?
A failing BCM can manifest in numerous ways. If you notice any of the following, it’s a strong indicator that your Body Control Module needs attention. A common diagnostic trouble code associated with these issues is U0140 – Lost Communication With Body Control Module.
- ✔ Intermittent or non-functional power windows, door locks, or interior lights.
- ✔ Erratic instrument cluster behavior or warning lights that come on for no reason.
- ✔ Key fob not working correctly or vehicle security system faults.
- ✔ HVAC (heating and air conditioning) controls not responding.
- ✔ The vehicle won’t start, but the battery and starter are confirmed to be good.
- ✔ Communication issues with other modules on the vehicle’s network.
A Straightforward Guide to Your BCM Swap
Installing your newly programmed 2015 Corvette BCM is a manageable task for a confident DIYer. The key is our cloning service, which handles the complex programming for you. Just follow these general steps (always consult your vehicle’s specific service manual for details and torque specs).
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Locate the BCM: The location varies by model. On a 2015 Corvette, it’s typically found in the left-hand side of the dash. For trucks like the Sierra or Silverado, it’s often under the steering column. Check your service manual for the exact location.
- Access and Disconnect: You may need to remove a few trim panels to gain access. Carefully unplug all electrical connectors from the old BCM. They have locking tabs, so be gentle to avoid damage.
- Swap the Modules: Unbolt or unclip the old BCM and remove it. Mount your new, pre-programmed module in its place, ensuring it is secure.
- Reconnect and Reassemble: Plug all the electrical connectors firmly into the new BCM. You’ll hear a click when they are properly seated. Reinstall any trim panels you removed.
- Power Up and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions: windows, locks, lights, radio, etc., to confirm the repair.
Important Post-Installation Steps
In some cases, your vehicle may require a couple of simple relearn procedures after the new BCM is installed. These are standard for many modern vehicles after a module replacement.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure the brake lights and traction control system function correctly.
Disclaimer: Vehicle systems are complex. Always refer to a factory service manual or consult with a qualified technician if you are unsure about any part of the process.

Frequently Asked Questions About Our BCM Cloning Service
Frequently Asked Questions
How does the cloning service work?
After you place your order, we will contact you with instructions to ship your original BCM to us. Once we receive it, our technicians will extract the unique vehicle data and transfer it to the replacement module. We then ship the plug-and-play BCM back to you, typically within 1-2 business days.
Is this really plug-and-play?
Yes. Because we clone your original module’s data, the replacement BCM is ready to be installed and used immediately without any additional programming or trips to the dealership.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM has failed and is causing major issues, the core data on the memory chip is still readable. Please contact us before ordering if your module is water-damaged, fire-damaged, or has been previously opened, as this can affect the cloning process.
Do I need to send my keys?
No, you do not need to send your keys. All the necessary security information is stored within the BCM itself, and our cloning process transfers it perfectly to the new unit.
Is there a core charge for this 2015 Corvette BCM?
No, there is no core charge. You are free to keep your original module after the service is complete.
What is your warranty policy?
We stand by our work with a comprehensive warranty on both the part and the programming service. Please see our full warranty page for specific details and duration.
