Restore Your Truck’s Electrical System with a Plug-and-Play Solution
Is your 2015 GMC Sierra 2500 or another compatible GM vehicle acting possessed? Flickering lights, malfunctioning power windows, a security system that won’t cooperate, or random warning lights on the dash are all classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, managing everything from your interior lights and power locks to your instrument cluster and security features. When it fails, it can cause a cascade of frustrating and unpredictable electrical gremlins.
Instead of facing a costly trip to the dealership for a new module and expensive programming fees, our professional cloning service provides a simple, reliable, and cost-effective solution. We transfer the essential data from your original BCM directly onto this replacement unit, making it a true plug-and-play part. This process ensures that your vehicle’s specific configuration, key programming, and mileage are all retained, eliminating the need for any additional programming after installation.
Common Symptoms of a Failing Body Control Module
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (staying on, not turning on, or flickering).
- ✔ The security system or anti-theft light is always on, preventing the engine from starting.
- ✔ False warnings appearing on the instrument cluster (e.g., ‘Service 4WD’, ‘Service StabiliTrak’).
- ✔ The radio or infotainment system randomly turns on or off.
- ✔ Unresponsive key fobs or remote start features.
- ✔ Complete loss of communication with the module, leading to multiple system failures.
From the Diagnostic Bay
We recently had a customer with a 2015 Silverado 2500—a sister truck to the Sierra—that was driving him crazy. His dome lights would stay on for hours, draining the battery, and his power locks only worked when they felt like it. He had replaced the battery and checked all the fuses, but the problems persisted. The dealership quoted him over $1200 for a new BCM and the labor to program it. He sent us his original module, we performed our cloning service, and shipped the replacement back the next day. He installed it in his garage in under 30 minutes and all the bizarre electrical issues were gone. He saved hundreds of dollars and the headache of a dealership visit.
Why Our Programming Service is the Smartest Fix for Your 2015 Sierra 2500 BCM
When your BCM fails, you typically have three options. The first is the dealership, which involves high-priced parts and labor, plus hours of programming. The second is a used module from a salvage yard, which will have the incorrect Vehicle Identification Number (VIN) and options, requiring a trip to the dealer for programming anyway. Our service is the third, and best, option. By cloning your original module, we create a perfect digital copy. The replacement 2015 Sierra 2500 BCM will think it’s been in your truck its entire life, ensuring seamless integration and functionality from the moment you plug it in.

Installation and Post-Install Notes
The BCM is typically located under the driver’s side of the dashboard, near the steering column. Installation is as simple as disconnecting the battery, unplugging the electrical connectors from the old module, and plugging them into your new one. While our service makes this a plug-and-play repair, some GM vehicles may require a couple of simple relearn procedures after installation.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This syncs the new BCM with the airbag system. This is only needed if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure proper operation of the brake lights and stability control systems.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What exactly is a BCM cloning service?
It’s a process where we extract the unique, vehicle-specific software and data from your original Body Control Module and flash it onto a replacement module. This makes the replacement an identical twin to your original, allowing it to work in your vehicle without any further programming.
Why do I have to send you my original module?
Your original BCM contains the VIN, security information for your keys, and specific option configurations for your truck. This data is essential to create a true plug-and-play replacement. Without it, the new module would not work correctly.
What if my original BCM is badly damaged or unreadable?
In most cases, even if the BCM has failed electronically, we can still retrieve the necessary data. If your module is physically destroyed (e.g., from a fire or major collision) or has severe water damage, please contact us before ordering to discuss options.
Will I need to have my keys reprogrammed?
No. Because we transfer all the security data from your original module, the replacement BCM will recognize your existing keys. You can just plug it in and start the car.
How long does the entire process take?
Our in-house processing time is very fast, typically one business day. The total turnaround time will depend on the shipping speeds you choose to send your module to us and for us to return it to you.
Is this part compatible with other vehicles?
Yes, this BCM fits a wide range of GM trucks and cars from 2014-2019, including the Silverado, Suburban, Tahoe, Corvette, and Impala. Please verify that your original module has part number 13594692 or one of the other compatible numbers listed.
