Restore Full Functionality to Your Truck’s Electronics
Is your 2015 GMC Sierra 3500 experiencing a host of bizarre and frustrating electrical problems? From flickering lights and malfunctioning power windows to random warning messages on your dash, these issues often point to a single culprit: a failing Body Control Module (BCM). The BCM acts as the central command center for your truck’s body electronics, and when it malfunctions, it can disrupt countless systems. This listing offers a straightforward, cost-effective solution: a replacement BCM, programmed with the data from your original unit, making installation simple and eliminating the need for an expensive trip to the dealership.
The Simple, Plug-and-Play Solution for Your 2015 Sierra 3500 BCM
Instead of dealing with the high costs and scheduling hassles of dealership programming, our service simplifies the entire process. You send us your original BCM, and we transfer all the critical vehicle-specific data—including key programming, security information, and optional feature settings—to a fully functional replacement module. We then ship the ready-to-install BCM back to you. This cloning process ensures that the replacement module is a perfect digital twin of your original, preserving all factory settings and functionality. It’s the most reliable way to get your truck back to normal without any additional programming required.
From the Diagnostic Bay
We recently had a 2015 Silverado come in with the strangest combination of issues. The radio would randomly turn off, the driver’s side window wouldn’t work, and the dome light flickered constantly. The owner had already replaced the battery and checked every fuse imaginable. After hours of chasing wires, we connected our diagnostic tool and found multiple communication fault codes originating from the BCM. A failing processor inside the module was corrupting the low-speed data network, causing chaos across multiple systems. Replacing the faulty module with a pre-programmed unit like this one solved every single issue instantly, saving the customer hundreds in diagnostic and programming fees at the dealer.
Is Your Sierra 3500 Exhibiting These BCM Failure Symptoms?
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) behaving erratically.
- ✔ Instrument cluster displaying incorrect information or random warning lights (e.g., ABS, Airbag, Service StabiliTrak).
- ✔ Vehicle security system acting up, causing alarm to sound randomly or preventing the engine from starting.
- ✔ HVAC (heating and air conditioning) controls not responding correctly.
- ✔ Communication issues with diagnostic scan tools, making it difficult to diagnose other problems.
Installation and Post-Install Procedures
Once you receive your programmed BCM, installation is typically straightforward. The module is located under the steering column on most Sierra and Silverado models. After disconnecting the battery, you can unplug the electrical connectors from the old module and install the new one. While our programming makes this a plug-and-play process, some GM vehicles may require one or two simple relearn procedures after installation:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool must be used to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure proper brake light operation and traction control system performance.
This BCM is a direct replacement for part numbers: 13592137, 13506935, 13506936, 13587704, and 13594764. It fits a wide range of 2015 GM vehicles, including the Chevrolet Silverado, Tahoe, Suburban, and Cadillac Escalade. Please verify your part number and check the fitment list to ensure compatibility.
Frequently Asked Questions
What is this cloning service and how does it work?
This is a programming service. You purchase this listing, we provide shipping instructions for you to send us your original BCM. We then extract the vehicle-specific data and transfer it to a replacement BCM. We ship the programmed replacement module back to you, ready for installation.
Will I need to get this BCM programmed by a dealer after installation?
No. The module arrives fully programmed to your vehicle’s specifications. It is a plug-and-play installation, though some minor relearn procedures may be required as noted in the description.
How long does the programming service take?
Our service is typically completed within 1-2 business days after we receive your original module. We will then ship the replacement module back to you, and you will receive tracking information at that time.
What if my original BCM is completely dead or unreadable?
In many cases, even if the BCM is non-functional, we can still retrieve the necessary data. If we are unable to read your module, we will contact you to discuss alternative programming options, which may involve using your vehicle’s VIN.
Is this a repair service for my original BCM?
No, this is not a repair service. You will not receive your original module back. You will receive a fully tested, replacement BCM that has been loaded with your vehicle’s original programming data.
