Restore Your Truck’s Functionality with a Perfectly Matched BCM
Are you dealing with baffling electrical issues in your 2015 Silverado? Flickering lights, malfunctioning power windows, a dead instrument cluster, or random warning messages are classic signs of a failing Body Control Module (BCM). As the central hub for your truck’s body electronics, a faulty BCM can turn your reliable workhorse into a source of constant frustration. Dealerships often charge a fortune for a new module plus expensive programming fees. Our solution gets you back on the road quickly and affordably.
We offer a professional cloning service for your 2015 Silverado BCM. Here’s how it works: You simply purchase this service, and we’ll provide instructions for shipping your original BCM to our facility. Our expert technicians will then transfer all the critical data—including VIN, mileage, and key programming—to this fully tested replacement module. The result? You receive a BCM that is 100% plug-and-play, eliminating the need for a trip to the dealer for programming. It’s the smart, simple fix for a complex problem.
A Technician’s Notebook
I remember a 2015 Sierra that came into the shop with the most bizarre symptoms. The radio would change stations on its own, the dome light wouldn’t turn off, and the driver’s side window only worked intermittently. The owner had already replaced the battery and checked all the fuses. A scan showed a dozen communication error codes (U-codes) pointing in every direction. This is a tell-tale sign. Instead of chasing individual components, we went straight for the BCM. After installing a cloned module like this one, every single issue vanished. It’s a reminder that when multiple, unrelated electronics fail at once, the BCM is almost always the culprit.
Is Your Truck Showing These Symptoms?
- ✔ Power windows or door locks operating erratically or not at all.
- ✔ Interior or exterior lights staying on or not turning on.
- ✔ The security system preventing the vehicle from starting.
- ✔ Inaccurate or dead gauges on the instrument panel.
- ✔ False warning lights, such as “Service StabiliTrak” or airbag warnings.
- ✔ Communication loss codes (e.g., U0100, U0140) when scanned with a diagnostic tool.
- ✔ A/C and climate control functions not working correctly.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your truck’s battery to prevent any electrical shorts.
- ✔ Locate the BCM: On most 2015 Silverado and Sierra models, the BCM is located under the steering column, to the left of the brake pedal. You may need to remove a lower dash panel for access.
- ✔ Disconnect and Remove: Carefully unplug all the electrical connectors from your original BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Mount your new, pre-programmed BCM in the same location. Reconnect all electrical connectors, making sure each one clicks securely into place.
- ✔ Final Steps: Reinstall any trim panels you removed and reconnect the negative battery terminal. Start the vehicle to confirm that the primary functions are restored.
Important Post-Installation Notes
While our cloning service makes this a plug-and-play repair, some GM systems require a ‘handshake’ after a new module is introduced. Be aware of the following:
- Airbag System Sync: If the 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 new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure brake lights and traction control work as intended. This is also done with a capable scan tool.
Disclaimer: Always consult a factory service manual or a qualified technician if you are unsure about any step. Specific procedures can vary slightly by vehicle model and options.

Frequently Asked Questions
Frequently Asked Questions
How does the cloning service process work?
After you place your order, we will contact you with simple, step-by-step instructions and a shipping address. You send us your original BCM. We then transfer its data to the replacement unit and ship it back to you, typically within 1-2 business days of receiving your module.
Is this really plug-and-play? Will I need a dealer?
Yes, for over 95% of installations. Because we clone your original data, the vehicle recognizes the new module as its own, avoiding the need for expensive dealer programming. The only exceptions are potential safety system relearns (like airbag or brake pedal) which may require a scan tool.
What happens if I don’t send in my original BCM?
This service is entirely dependent on receiving your original module. We cannot ship the replacement BCM until we have cloned the data from your current one. This ensures perfect compatibility with your truck’s specific options.
Is there a core charge for my old part?
No, there is no core charge. The cloning process requires your original module, but you do not need to pay an additional fee. We will keep your old, non-functional module.
How do I find the part number on my BCM?
The part number is printed on a white label directly on the BCM housing. You will need to locate and likely remove the module to read it clearly. Matching this number is the best way to ensure compatibility.
