Restore Your GM Truck’s Brain Without Dealership Hassles
As a technician with over two decades of experience, I’ve seen firsthand the frustration a failing Body Control Module (BCM) can cause. Your 2015 Sierra or other compatible GM vehicle suddenly develops a mind of its own: the radio won’t turn off, the power windows are dead, the security light flashes for no reason, or worse, it refuses to start. These aren’t random glitches; they’re classic signs that the central command center for your vehicle’s electronics is failing. A trip to the dealership often means a hefty bill for the part, labor, and mandatory programming. Our service is the smart, cost-effective alternative.
We offer a professional cloning service for your 2015 Sierra BCM. This isn’t just a part in a box; it’s a complete, ready-to-install solution. You simply send us your original BCM, and we transfer all of its critical data—including VIN, mileage, and key information—to a fully tested replacement unit. The result? A true plug-and-play module. You get your truck back to normal without expensive diagnostic tools or a trip to the dealer. We handle the complex programming so you can focus on the simple installation.
From the Diagnostic Bay
Just last month, a 2015 Sierra 1500 was towed to our shop. The owner was at his wit’s end. The horn would blare randomly, the interior lights flickered constantly, and the dash was lit up with communication error codes, primarily a U0140 (Lost Communication With Body Control Module). He had already replaced the battery, thinking it was a simple voltage issue. After confirming the BCM was the culprit, we performed this exact cloning service. Within an hour of receiving the cloned module back, he had it installed himself. All the bizarre electrical gremlins were gone. It’s a common story, and this service is the most reliable fix.
Is Your Sierra Showing These BCM Failure Signs?
A failing BCM can manifest in confusing ways. If you’re experiencing any of the following, your BCM is the likely cause:
- ✔ Erratic or non-functional power windows, door locks, and interior/exterior lights.
- ✔ The security or anti-theft system light stays on, preventing the engine from starting.
- ✔ The radio or infotainment system behaves strangely or won’t turn off.
- ✔ Multiple unrelated warning lights appear on the dashboard.
- ✔ Communication-related Diagnostic Trouble Codes (DTCs) like U0140, U0155, or B1001 are present.
- ✔ Complete loss of power to various accessories.
Your Straightforward BCM Installation Guide
Installing your cloned BCM is a manageable job for a DIY enthusiast. While the exact location varies slightly by model (see fitment list), it’s typically found under the driver’s side dash.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On most Sierra and Silverado models, the BCM is located under the steering column, often secured with a few small bolts or clips. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug the multiple wiring harnesses connected to the module. Press the release tabs firmly and pull the connectors straight out. Avoid pulling on the wires themselves. Once disconnected, remove the old BCM.
- Install the Cloned BCM: Mount the new, cloned BCM in the same position and secure it. Reconnect all wiring harnesses, making sure each one clicks firmly into place.
- Reconnect Power: Reattach the negative battery terminal.
- Test and Verify: Start the vehicle and test all body functions—windows, locks, lights, radio, etc.—to confirm the repair was successful.

Frequently Asked Questions
How does this cloning service actually work?
After you place your order, we’ll contact you with instructions to ship your original BCM to us. Once we receive it, our technicians extract the unique programming and transfer it to a replacement module. We then ship both your original module and the ready-to-install replacement back to you.
Do I get my original BCM back?
Yes, absolutely. Your original module is always returned to you along with the newly programmed replacement unit. We do not keep your old part.
Will I need to do any programming after installation?
No, the main purpose of our service is to eliminate the need for any additional programming. However, on some models, a couple of simple relearn procedures may be necessary. For instance, if your airbag light is on, a ‘Setup SDM Primary Key in BCM’ procedure might be needed. Similarly, a ‘Brake Pedal Position Relearn’ may be required for proper brake light and traction control function. These are minor steps compared to a full module programming.
Is this a guaranteed fix for my vehicle’s electrical problems?
This service corrects any issue caused by a faulty BCM. It’s crucial to properly diagnose the BCM as the source of the problem. If you’re experiencing the common symptoms we’ve listed, a failing BCM is the most likely culprit.
How long does the entire process take?
We perform the cloning service the same day we receive your module. The total turnaround time will depend on shipping times to and from our facility. We will send you a tracking number as soon as your modules are on their way back to you.
