Restore Your Truck’s Functionality and End Electrical Frustration
If you’re dealing with bizarre electrical issues in your 2015 Silverado or other compatible GM vehicle, you know how maddening it can be. Lights flickering for no reason, power windows with a mind of their own, or a security system that won’t cooperate—these are classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s comfort and convenience features. When it fails, it can feel like your truck is haunted. Dealerships will often quote you a hefty price for a new module plus hundreds more for programming. We offer a smarter, more affordable solution.
This is a replacement BCM that comes perfectly programmed for your vehicle through our simple cloning service. You send us your original BCM, and we transfer all the critical vehicle-specific data—including key information and optional features—to this replacement unit. The result? A true plug-and-play module that gets you back on the road without any need for dealer intervention or expensive scan tools. This service for the 2015 Silverado BCM is the most reliable way to solve your electrical problems for good.
From the Diagnostic Bay: The Case of the Haunted Silverado
I remember a 2015 Sierra 1500 (which uses the same BCM) that came into the shop last winter. The owner was at his wit’s end. The dome lights would randomly turn on while driving, the radio would shut off, and the key fob worked only intermittently. He’d already replaced the battery and checked all the fuses. Another shop told him it might be a wiring issue, which would mean hours of costly diagnostic labor. After connecting my scan tool, I noticed several communication loss codes (U-codes) pointing to the BCM. Instead of a wild goose chase through the wiring harness, we identified the BCM as the internal failure point. Our cloning service is the exact fix for this scenario—it provides a cost-effective, pre-programmed part that eliminates the guesswork and gets the vehicle fixed right the first time.
Is Your Truck Plagued by These Electrical Gremlins?
A failing BCM can manifest in numerous ways. As the central hub for body electronics, its failure impacts many systems. Here are the most common symptoms I’ve seen in my 20+ years of experience:
- ✔ Erratic interior or exterior lights (flickering, staying on, or not working at all).
- ✔ Power windows, door locks, or mirrors behaving unpredictably or failing completely.
- ✔ The security system acting up, causing alarm issues or a no-start condition.
- ✔ Key fobs that stop working or only work sporadically.
- ✔ Dashboard warning lights illuminating without a clear cause.
- ✔ Communication error codes stored in the system, such as U0140 (Lost Communication With Body Control Module).
- ✔ Wipers or the horn activating on their own.
Your Straightforward BCM Installation Guide
Our cloning service makes the physical swap simple. Once you receive your programmed module from us, follow these general steps. The BCM is typically located under the steering column on the driver’s side.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Access the Module: Remove any lower dash panels necessary to gain clear access to the BCM. It’s often mounted to a bracket near the steering column.
- Disconnect and Remove: Carefully unplug the multiple electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting location.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely reconnect all the electrical connectors. You should hear a click as they lock into place.
- Final Steps: Reinstall the dash panels and reconnect the negative battery terminal. Start the vehicle and test all functions like lights, locks, windows, and wipers to confirm the repair.
Important Post-Installation Information
While our programming handles the vast majority of functions, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure correct brake light operation and to prevent issues with the traction control system.
Disclaimer: Always consult a factory service manual or a qualified technician for procedures specific to your vehicle’s exact make and model.

Frequently Asked Questions
Frequently Asked Questions
How does the mail-in programming service work?
It’s simple! After you purchase, we will contact you with instructions to ship your original BCM to us. Once we receive it, our technicians will clone its data to the replacement module and ship it back to you, typically within 1-2 business days. This ensures all your vehicle’s settings are preserved.
Do I need to do any programming myself?
No. The module you receive from us will be fully programmed and ready for installation. This service eliminates the need for expensive dealer programming. Some minor relearn procedures, like for the airbag or brake pedal sensor, may be needed after installation in specific cases.
What if my original BCM is badly damaged or unreadable?
In the vast majority of cases, we can still retrieve the necessary data even from a non-functional module. If for some reason your module’s data is completely unrecoverable, we will contact you to discuss options and provide a full refund if we cannot proceed.
Is there a core charge for this part?
No, there is no core charge. We need your original module to perform the data cloning service, but you do not need to worry about any additional core fees.
Why is cloning better than buying a used BCM?
A standard used BCM will contain the VIN and security information from its donor vehicle, and it will not work in your truck without being reprogrammed by a dealer. Our cloning service transfers YOUR vehicle’s specific data, making the replacement a true plug-and-play part that works correctly right out of the box.
