Restore Your Truck’s Electrical System with a Hassle-Free Solution
If you’re dealing with baffling electrical issues in your 2015 GMC Sierra 1500—like power windows that have a mind of their own, a radio that won’t turn on, or dashboard lights flickering randomly—you’ve likely pinpointed the culprit: a failing Body Control Module (BCM). As the central command for your truck’s body electronics, a faulty BCM can cause a cascade of frustrating and unpredictable problems. Simply swapping it with a new or used one won’t work, as these modules are coded specifically to your truck’s VIN and factory options. A trip to the dealership often means a hefty bill for the part, labor, and programming.
We offer a straightforward and reliable alternative. This is a complete programming service for your 2015 Sierra 1500 BCM. You send us your original module, and our expert technicians will transfer all the critical data—including your VIN, mileage, and specific vehicle configuration—to a fully tested replacement BCM. We then ship the ready-to-install module back to you. The result is a true plug-and-play component that restores full functionality without requiring any expensive dealer intervention. It’s the smart, cost-effective way to get your truck back to 100%.
From the Diagnostic Bay: The Case of the Haunted Silverado
A few months back, a 2015 Silverado (a sister truck to the Sierra) was towed to my shop. The owner was at his wit’s end. The horn would blare randomly, the interior lights wouldn’t turn off, and the anti-theft system would engage, preventing it from starting. He’d been quoted over $1,200 by the dealer for a new BCM and programming. I connected my scan tool and found a slew of U-codes, all pointing to a communication breakdown originating from the BCM. Instead of the expensive dealer route, we used this exact cloning service. We had the original BCM out in 20 minutes, shipped it for programming, and got the replacement back a few days later. It plugged right in, and every single issue was resolved instantly. The customer saved hundreds and avoided a complex dealer visit.
Is Your Truck Showing These Symptoms?
A failing BCM can manifest in many ways. If you’re noticing any of the following, your Body Control Module is the likely cause:
- ✔ Erratic power windows, door locks, or mirrors.
- ✔ Interior or exterior lights not working correctly or staying on.
- ✔ The radio or infotainment system is unresponsive.
- ✔ The anti-theft or security light is illuminated, causing a no-start condition.
- ✔ Intermittent warning lights on the instrument cluster.
- ✔ Communication-related Diagnostic Trouble Codes (DTCs), such as U0140, U0155, or U0100.
- ✔ A/C and climate control functions are not working as they should.
A Straightforward Guide to Installation
Our cloning service makes the physical installation simple. Once you receive your pre-programmed BCM, follow these general steps:
- Safety First: Always disconnect the negative terminal from your truck’s battery before working on any electronic components.
- Locate the BCM: On the 2015 Sierra 1500, the Body Control Module is typically located under the driver’s side of the dashboard, near the steering column.
- Remove the Old Module: Carefully unplug the electrical connectors from the original BCM. They have locking tabs that need to be depressed. Once unplugged, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location. Securely reconnect all the electrical connectors, ensuring they click into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—windows, locks, lights, radio, etc.—to confirm the repair was successful.
Important Post-Installation Notes
In some cases, additional steps may be required after installation:
- 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 recalibration might be necessary to ensure correct brake light and traction control operation.
Disclaimer: Always consult a factory service manual or a qualified professional for procedures specific to your vehicle.

Frequently Asked Questions
How does the programming service work?
After you place your order, we will provide you with instructions to ship your original BCM to us. Once we receive it, our technicians will clone the data to a replacement module and ship it back to you, typically within 1-2 business days.
Is this a guaranteed fix for my vehicle’s problems?
This service resolves issues directly caused by a faulty BCM. If your vehicle’s symptoms match the common failure signs, this is a highly effective solution. However, proper vehicle diagnosis is key, as wiring or other component failures can sometimes mimic BCM issues.
Do I need to send my keys or any other parts?
No. We only need your original Body Control Module. The security and key information is stored within the module, which we will transfer to the new unit.
Will my mileage be correct after installation?
Yes. The cloning process transfers all vehicle-specific data, including the correct mileage, from your original BCM to the replacement one.
What if I have an airbag light on after installing the new BCM?
This can happen occasionally. It requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by a repair shop with a professional-grade diagnostic tool to sync the systems and clear the light.
Is there a core charge?
No, there is no core charge for this service. You can keep your original non-working module.
