Restore Order to Your Vehicle’s Electrical System
Are you battling frustrating and unpredictable electrical issues in your 2015 GMC Yukon XL 1500 or another compatible GM vehicle? One moment the power windows work, the next they don’t. The radio might shut off randomly, or you’re seeing bizarre warning lights flash across the dash. These aren’t just annoyances; they’re 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 falters, it can create chaos. Dealerships often quote sky-high prices for a new module plus mandatory programming fees. We offer a smarter, more affordable solution.
This is a comprehensive mail-in cloning service. You send us your original BCM, and our expert technicians will transfer all the critical vehicle-specific data—including VIN, mileage, and key programming—to a fully tested replacement module. We then ship the plug-and-play replacement back to you, ready for installation without any need for a trip to the dealer. It’s the most reliable way to get your truck back to 100% functionality.
From the Diagnostic Bay
I remember a 2015 Sierra 1500 that came into the shop with the owner at his wit’s end. The truck had a laundry list of ‘ghost’ problems: the dome light would stay on, the driver’s side power lock was intermittent, and the security light would flash, sometimes preventing it from starting. He’d already replaced the battery and checked grounds. A scan showed a slew of U-codes, specifically U0140 (Lost Communication With Body Control Module). This pointed directly to an internal BCM failure. Instead of a costly new module and programming, we performed a cloning service just like this one. After a 15-minute install of the cloned BCM, every single issue was gone. It’s a textbook example of how a failing BCM can mimic a dozen other problems, and why this service is such an effective fix.
Is Your Vehicle Showing These Symptoms?
A faulty 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 (headlights, taillights) staying on or not turning on.
- ✔ The security system acting up, causing no-start conditions or false alarms.
- ✔ The horn honking unexpectedly.
- ✔ Instrument panel gauges behaving erratically or going dark.
- ✔ Diagnostic Trouble Codes (DTCs) related to communication, such as U0140, U0155, or other U-codes.
- ✔ Wipers activating on their own or not working when commanded.
Our Simple Mail-In Cloning Process
Getting your vehicle fixed is easy. After your purchase, we will contact you with clear, step-by-step instructions and a shipping address. You simply mail us your original BCM. Once we receive it, our technicians perform the data transfer to the replacement 2015 Yukon XL 1500 BCM within 1-2 business days and ship it right back to you. You’ll receive a tracking number the moment it’s on its way.
A Straightforward Guide to Installation
Installing your newly programmed BCM is a manageable job for a DIYer or a quick task for any professional mechanic. While locations vary slightly, it’s typically found under the driver’s side dash.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On most trucks like the Yukon, Sierra, and Silverado, the BCM is located 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 the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Seat the replacement BCM into the mounting bracket and securely plug in all the electrical connectors. You’ll hear a ‘click’ when they are properly seated.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—windows, locks, lights, wipers, etc.—to confirm the repair.
Important Post-Installation Notes
Our cloning service makes this as close to plug-and-play as possible. However, in some GM vehicles, a couple of quick relearn procedures may be needed after installation. This is normal and does not indicate a problem with the module.
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor relearn may be necessary on some models.
Disclaimer: Always consult a factory service manual or a qualified technician for procedures specific to your vehicle.

Frequently Asked Questions
How does the mail-in service work?
After you place your order, we’ll email you detailed instructions and our shipping address. You send us your original BCM. We clone the data to a replacement unit and ship it back to you, typically within 24-48 hours of receiving it.
Is this really plug-and-play?
Yes, because we clone your vehicle’s original data, the replacement BCM is ready to install without any dealer programming. In some cases, minor relearn procedures like for the airbag or brake pedal sensor may be needed, which is standard for this type of repair.
Do I need to send my keys?
No. All the necessary security information is stored within your original BCM. We transfer this data, so your existing keys will work perfectly with the replacement module.
What if my original BCM is completely dead or not communicating?
In most cases, even if the BCM has failed, we can still extract the necessary data. Please contact us before ordering if your module has severe water or fire damage.
Is there a core charge?
No, there is no core charge for this service. You are welcome to keep your original module after the service is complete.
