Restore Full Electrical Function to Your GM Vehicle
Are you battling a storm of bizarre electrical problems in your 2015 Chevrolet Silverado, GMC Sierra, or other compatible GM vehicle? Flickering lights, malfunctioning power windows, a security system that has a mind of its own, or warning lights that won’t turn off are all classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can make driving frustrating and unpredictable. Dealerships often quote expensive repairs that involve costly new parts and programming fees. We offer a simple, cost-effective, and reliable solution.
This is a replacement BCM that comes fully programmed through our mail-in cloning service. By transferring the data from your original module to this replacement unit, we create a true plug-and-play component. This process ensures that all your vehicle’s specific settings, key fob information, and security data are retained. You get a fully functional BCM without the need for a trip to the dealer for expensive programming.
From the Diagnostic Bay
We had a 2015 Sierra 1500 come in that was driving the owner crazy. The radio would randomly change stations, the interior dome lights would stay on, and the key fob only worked intermittently. He had already replaced the battery and checked all the fuses. After connecting our diagnostic tool, we saw multiple communication errors pointing towards the BCM. Instead of a costly new module and a full system reprogram, we performed a cloning service just like this one. We sent him the programmed replacement, he plugged it in, and every single one of his electrical gremlins vanished. It’s a powerful fix for a complex problem.
Is Your Vehicle Showing These Symptoms?
- ✔ Intermittent or non-working power windows, locks, or mirrors.
- ✔ Erratic interior or exterior lighting behavior.
- ✔ The security system or anti-theft light is always on, preventing the engine from starting.
- ✔ Key fobs are not being recognized by the vehicle.
- ✔ Unexplained battery drain when the vehicle is off.
- ✔ False warnings on the dashboard instrument cluster (e.g., ‘Door Ajar’).
- ✔ Malfunctioning windshield wipers or climate control systems.
How Our Simple Programming Service Works
Our goal is to make this process as straightforward as possible. After you complete your purchase, we will contact you with detailed instructions and a shipping address. You will need to carefully remove your original BCM and ship it to us. Once we receive your module, our technicians will use specialized equipment to extract the essential programming and security data. This data is then flawlessly transferred to the replacement BCM. We then ship both your original module and the ready-to-install replacement back to you. The result is a part that is perfectly matched to your vehicle’s VIN and options, eliminating the need for any additional on-vehicle programming.
Post-Installation Checks for Your 2015 Silverado BCM
While our programming service makes the installation of your 2015 Silverado BCM as simple as possible, some GM vehicles may require a final sync or relearn procedure for specific subsystems. These are typically simple procedures that can be performed with a capable diagnostic scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure correct brake light operation and stability control function, a brake pedal position sensor recalibration may be required on certain models.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
This BCM is a direct replacement for the following part numbers: 13592137, 13506935, 13506936, 13587704, 13594764. Please verify your part number before ordering to ensure compatibility.
Frequently Asked Questions
What exactly does the Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related functions. This includes power windows, door locks, interior and exterior lights, the security system, climate controls, and more. It acts as a central hub for these electronic features.
Why is cloning my original BCM necessary?
Your original BCM contains vital security information, key fob programming, and vehicle-specific option configurations. Cloning this data to the replacement module makes it a true plug-and-play part. Without this service, a new BCM would not work and would require expensive programming from a dealership.
How long does the programming service take?
We pride ourselves on a fast turnaround. Once we receive your original module, the programming and testing process is typically completed within 1-2 business days. We then ship your modules back to you promptly.
Is this really a plug-and-play solution?
Yes, for over 99% of installations. Because we clone your vehicle’s exact data, the replacement BCM is ready to be installed and function immediately. In rare cases, a simple relearn procedure, like for the airbag or brake pedal sensor, may be needed as mentioned above.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is not functioning in the vehicle, we can still extract the necessary data directly from its memory chip. Please contact us before ordering if your module is severely damaged by water or fire.
