Tired of Your Truck’s Unpredictable Electronics?
If you’re dealing with flickering lights, power windows with a mind of their own, or a dashboard that lights up like a Christmas tree for no reason, you’re not alone. These frustrating electrical gremlins in your 2015 Silverado 2500 are often traced back to one component: a failing Body Control Module (BCM). The BCM is the central command center for your truck’s body electronics, and when it starts to fail, it can cause widespread, chaotic issues. Taking it to the dealership often means a hefty bill for diagnostics, the part itself, and expensive programming fees. We offer a smarter, more direct solution.
The Simple, Cost-Effective Repair: A Pre-Programmed BCM
This is a replacement Body Control Module, compatible with part number 13594768 and others, that arrives at your doorstep ready for installation. How? We use a specialized cloning service. After your purchase, you simply ship us your original BCM. Our expert technicians will extract the unique, vehicle-specific data and transfer it directly onto this replacement unit. We then ship the programmed module back to you. This process ensures all your vehicle’s original settings and key information are preserved, eliminating the need for a trip to the dealer for programming. It’s the most efficient way to get your truck back to 100% functionality.
From the Diagnostic Bay
I remember a 2015 Sierra 2500 (which uses the same BCM) that came into my shop last winter. The owner was at his wit’s end. The radio would randomly shut off, the dome lights would stay on, and occasionally, the truck wouldn’t recognize the key fob. He’d already replaced the battery and checked all the fuses. After connecting my scan tool, I noticed several U-codes (communication errors) pointing to a loss of communication with multiple systems. Instead of chasing each individual symptom, experience told me to look at the network’s hub—the BCM. By monitoring the data bus, we saw the BCM was intermittently dropping offline, causing the chaos. A cloned 2015 Silverado 2500 BCM like this one solved every single issue in one go, saving the customer hundreds compared to the dealership’s quote.
Is Your Truck Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, your Body Control Module is the likely culprit:
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system acting up, or the key fob not being recognized.
- ✔ The horn honking randomly or not working when pressed.
- ✔ Multiple, unrelated warning lights on the instrument cluster.
- ✔ Communication error codes stored, such as U0140 (Lost Communication With Body Control Module).
A Straightforward Guide to Installation
Installing your pre-programmed BCM is a manageable job for a DIYer with basic tools. While the exact location can vary slightly, it’s typically found under the steering column on the driver’s side.
- Safety First: Always disconnect the negative terminal from your truck’s battery before working on any electronic components.
- Locate the BCM: On most GM trucks and SUVs from this era, the BCM is mounted to a bracket under the driver’s side of the dashboard, near the steering column. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug all electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all the electrical connectors. Ensure they click into place.
- Reconnect and Test: Reinstall any panels you removed and reconnect the negative battery terminal. Start the vehicle and test all functions: lights, windows, locks, horn, and wipers to confirm the repair.
Important Post-Installation Information
Because this module is cloned from your original, most functions will work immediately. However, in some cases, additional steps may be needed:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a simple “Setup SDM Primary Key in BCM” procedure is required. This syncs the airbag system with the new BCM and must be performed with a professional-grade scan tool.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn might be necessary to ensure the brake lights and traction control system function correctly. This is also performed with a scan tool.
Disclaimer: Always consult a factory service manual for your specific vehicle for detailed instructions and torque specs. If you are not comfortable performing this repair, we recommend seeking a qualified technician.

Frequently Asked Questions
After you place your order, we’ll provide instructions for shipping your original BCM to us. Our technicians will then copy its programming and security data to the replacement module. We ship the newly programmed module back to you, typically within 1-2 business days of receiving your old one.
No. Because we are cloning all the data from your original module, including the key information, your existing keys will work seamlessly with the replacement BCM.
Yes, for the most part. The module arrives programmed for your vehicle. In some instances, as noted above, a post-installation procedure like an airbag sync or brake pedal relearn may be needed, which requires a scan tool. However, the core programming that requires dealer-level access is already done.
If your BCM is non-communicative (e.g., water damaged, burned), we may not be able to retrieve the data. Please contact us before ordering if your module is severely damaged so we can discuss potential options.
No, there is no core charge. We need your original module to perform the cloning service, but you do not need to return it to us afterward for a refund.
