Restore Your Truck’s Electrical System with a Hassle-Free Solution
As a technician with over 20 years on the floor, I’ve seen it all when it comes to modern vehicle electronics. If your 2015 Silverado 1500 is acting possessed—with flickering lights, unresponsive power windows, a haywire security system, or intermittent no-start conditions—the Body Control Module (BCM) is often the culprit. The BCM is the central command center for your truck’s body electronics, and when it fails, it creates a cascade of frustrating, seemingly unrelated problems. Dealerships will charge a fortune for a new module plus a separate, mandatory programming fee. We offer a simpler, more affordable path back to reliability.
This is a replacement 2015 Silverado 1500 BCM that comes fully programmed with your vehicle’s specific data. Our professional cloning service transfers all the critical information from your original, failing BCM to this fully tested replacement unit. This means no expensive trips to the dealer for programming. It arrives at your door ready for installation, making it a true plug-and-play fix.
How Our Simple Mail-In Programming Service Works:
Getting your truck fixed is straightforward. After you place your order, we will contact you with clear, step-by-step instructions to ship your original BCM to our facility. Once we receive it, our expert technicians will clone the data to your replacement module within 1-2 business days and ship it right back to you. You’ll receive tracking information the moment it’s on its way. Best of all, there’s no core charge—you can keep your original module.
Is Your GM Vehicle Showing These BCM Failure Signs?
- ✔ Power windows, door locks, or interior lights working erratically or not at all.
- ✔ The security or anti-theft system light is on, preventing the engine from starting.
- ✔ Horn, wipers, or radio functions are intermittent or have stopped completely.
- ✔ False warning messages appearing on the driver information center (DIC).
- ✔ Diagnostic trouble codes (DTCs) related to communication loss, such as U0140, U0155, or other ‘U’ codes.
- ✔ Inconsistent key fob operation.
A Technician’s Notebook: The Ghost in the Machine
A customer brought in a 2015 Sierra 2500, a sister truck to the Silverado, with a truly baffling issue. The radio would randomly shut off, the driver’s side window would stop working for hours, and occasionally the truck wouldn’t recognize the key fob. He’d already replaced the battery and checked fuses. After hooking up my scan tool, I saw multiple communication loss codes pointing to the BCM. Instead of a costly new unit and programming, we used a service just like this. We pulled his old BCM, sent it for cloning, and had the replacement back in a few days. After a 15-minute install, every single ghost in his machine was gone. This service saves time, money, and a ton of diagnostic headaches.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your truck’s battery before working on any electronic components.
- ✔ Locate the BCM: On most 2015 GM trucks like the Silverado and Sierra, the BCM is located under the steering column, behind the lower dash panel. You may need to remove a few plastic trim pieces for access.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs, so be gentle. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New BCM: Mount your pre-programmed replacement BCM in the same location and securely reconnect all the electrical harnesses. Ensure they click into place.
- ✔ Post-Installation Checks: Reconnect the battery terminal. Start the vehicle and test all body functions: lights, windows, locks, radio, etc.
- ✔ Final Relearn Procedures (If Needed): In some cases, you may need to perform a relearn procedure. If the airbag light is on, a professional scan tool is needed for the ‘Setup SDM Primary Key in BCM’ function. A ‘Brake Pedal Position Relearn’ might also be required for proper brake light and traction control operation. Always consult a factory service manual for specifics.

Frequently Asked Questions
How does the cloning service work?
After you purchase, we’ll provide instructions to mail your original BCM to us. We then copy its unique vehicle data onto this replacement module and ship it back to you, ready to install. This avoids any need for dealership programming.
Is this a plug-and-play part?
Yes. Because we program it using your original module’s data, it is plug-and-play. In some rare cases, a minor relearn procedure like for the brake pedal position sensor may be needed, but the core functions will work immediately.
What if my part number is slightly different?
This module replaces several part numbers, including 13592137, 13506935, 13506936, and 13594764. As long as your part number is on this list, it will be compatible.
How long does the entire process take?
Once we receive your original BCM, our cloning service typically takes 1-2 business days. The total time will depend on shipping times to and from our facility. We always ship the programmed module back promptly with tracking.
What if the airbag light comes on after installation?
This can happen occasionally. It means the new BCM needs to be synced with the airbag system’s SDM. This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure, which is a quick task for any competent repair shop.
