Restore Full Electrical Function to Your Truck
Is your 2015 GMC Sierra 3500 experiencing bizarre electrical problems? Flickering lights, malfunctioning power windows, a security system that acts up, or warning lights that won’t go away are all classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your truck’s body electronics, and when it fails, it can cause a cascade of frustrating and seemingly unrelated issues. Don’t let these electrical gremlins keep your truck off the road. This is a direct replacement, programmed solution for your vehicle.
From the Diagnostic Bay
We had a 2015 Sierra 2500 in the shop that was driving the owner crazy. The radio would randomly turn off, the dome light would stay on, and the power locks worked intermittently. He had already replaced the battery and checked all the fuses. After connecting our diagnostic scanner, we saw multiple communication errors pointing towards the BCM. Instead of a costly new module and hours of programming at the dealership, we used our cloning service. We transferred the data from his faulty BCM to a replacement unit. Once installed, every single electrical issue was resolved instantly. It’s a powerful fix that saves both time and money.
Common Symptoms of a Failing BCM
- ✔️ Intermittent or non-working power windows, door locks, or mirrors.
- ✔️ Headlights, taillights, or interior lights behaving erratically.
- ✔️ The security system or keyless entry failing to operate correctly.
- ✔️ Unexplained battery drain when the vehicle is off.
- ✔️ False warning lights on the instrument cluster, such as the airbag or brake light.
- ✔️ Wipers or horn activating on their own or not working at all.
- ✔️ Communication errors with other vehicle modules when scanned.
The Simple, Plug-and-Play Solution for Your 2015 Sierra 3500 BCM
Dealerships will often charge a fortune for a new BCM, plus additional fees for programming it to your vehicle’s specific Vehicle Identification Number (VIN) and options. Our service bypasses this complexity entirely. We offer a straightforward cloning service that makes this a simple, plug-and-play repair. By transferring the exact data from your original BCM to this replacement unit, we create a module that is ready for immediate installation with no further programming required.

Post-Installation Information
While our goal is a 100% plug-and-play experience, some GM vehicles may require a simple relearn procedure after the new BCM is installed. These are not programming steps but rather synchronization processes that can sometimes be necessary.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure may be needed. This is a quick sync that can be performed with a professional-grade scan tool.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration might be required to ensure proper brake light and traction control operation.
Always consult a factory service manual or a qualified technician if you are unsure about any post-installation steps.

Frequently Asked Questions
What is a BCM cloning service?
Our cloning service involves transferring the unique programming and vehicle-specific data from your original, faulty BCM to a fully functional replacement unit. This ensures the replacement module is a perfect match for your truck’s VIN and options, making it a true plug-and-play solution.
Why is this better than buying a used BCM from a junkyard?
A used BCM from another vehicle will not work in your truck without being reprogrammed by a dealer or a specialized shop. It contains the VIN and options from the donor vehicle. Our service provides you with a module that is already programmed specifically for your truck, saving you that expensive and time-consuming step.
Do I need any special tools to install this?
For most models, you will only need basic hand tools to access and replace the BCM, which is typically located under the steering column or on the firewall. No programming tools are required. However, as noted, a professional scan tool may be needed for post-install sync procedures if a warning light appears.
How long does the entire process take?
Once we receive your original module, our programming service is typically completed within 24-48 business hours. The total time will depend on shipping times to and from our facility. We always ship the programmed module back to you with tracking.
Is there a core charge or do I get my old module back?
There is no core charge for this service. We only need your original module to perform the data transfer. We do not return the original non-working module.
