Are you dealing with baffling electrical issues in your 2015 GMC Yukon or another compatible GM vehicle? Flickering lights, malfunctioning power windows, a security system that acts up, or strange warning messages on your dash are 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 fails, it can cause a cascade of frustrating and seemingly unrelated problems. Many owners are told the only solution is an expensive trip to the dealership for a new module followed by costly programming. We offer a smarter, more direct solution.
This is a replacement Body Control Module that comes ready for installation, thanks to our professional cloning service. Instead of dealing with the expense and hassle of dealership programming, you simply send us your original BCM. We transfer all the critical vehicle-specific data—including VIN, mileage, and key information—to this replacement unit. The result? A truly plug-and-play module that restores function without any additional calibration or dealer visits. It’s the most efficient way to get your truck back to 100%.
From the Diagnostic Bay: The Ghost in the Machine
I remember a 2015 Sierra 1500 that came into the shop with a list of complaints that made no sense together. The radio would turn off randomly, the driver’s side window wouldn’t go down, and the dome lights would stay on, draining the battery overnight. The owner had already replaced the battery and checked all the fuses. After hooking up my scan tool, I saw a slew of U-codes (communication errors) pointing to a network problem. In my 20+ years of experience, this pattern almost always leads back to one component: a failing BCM. The internal processors start to break down, sending corrupt data across the vehicle’s network, creating these ‘ghost’ problems. We performed our cloning service, and the replacement 2015 Yukon BCM (same family) had that truck running perfectly in under an hour. It’s a fix I’ve done hundreds of times.
Common Signs of a Failing BCM
If you’re experiencing any of the following, a faulty BCM is the likely culprit. A failing module can often generate communication-related Diagnostic Trouble Codes (DTCs) like U0100, U0140, or other U-series codes.
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ The security system preventing the vehicle from starting (anti-theft light flashing).
- ✔ Erratic behavior from the radio or infotainment system.
- ✔ False warnings on the instrument cluster (e.g., ‘Service StabiliTrak’).
- ✔ Inconsistent operation of windshield wipers.
A Straightforward Guide to Your BCM Swap
Our cloning service makes the physical installation a simple parts swap. Here is a general guide to get you started.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate Your BCM: On most compatible trucks and SUVs like the Yukon, Tahoe, and Silverado, the BCM is located under the steering column, to the left of the brake pedal. On other models like the Corvette or CTS, it may be in the dash or on a hinge pillar. A quick search for your specific model will confirm its location.
- Remove the Old Module: Carefully unplug the electrical connectors. Most have a locking tab that needs to be depressed or lifted. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Package and Ship: Securely package your original BCM and ship it to us. We will contact you with detailed shipping instructions right after your purchase. Please ensure your contact information is correct at checkout.
- Install the Replacement: Once you receive the programmed module back from us, simply mount it in place and reconnect all the electrical connectors. Reconnect your battery.
- Final Checks: Start the vehicle and test all body functions—lights, locks, windows, radio, etc. Note the post-installation procedures below, as they may be required.
Post-Installation Notes
While our programming makes this a plug-and-play repair, some vehicle systems may require a relearn procedure after the BCM and battery have been disconnected.
- 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’ function. This syncs the new BCM with the airbag system. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure correct brake light and traction control operation.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual or a qualified technician for procedures specific to your vehicle.

Frequently Asked Questions
How does the mail-in cloning service work?
After you purchase, we’ll contact you with instructions to ship your original BCM to our facility. Once we receive it, we transfer its unique data to the replacement module and ship it back to you, typically within 1-2 business days. This makes the replacement plug-and-play.
Do I really not need to go to the dealer?
That’s correct. Because we clone your original module’s data, the replacement BCM is already configured for your vehicle’s specific VIN and options. This process completely bypasses the need for expensive dealership programming.
What if my airbag light comes on after I install it?
In some cases, the airbag system (SDM) needs to be re-synced with the BCM. This is a simple procedure called ‘Setup SDM Primary Key in BCM’ that can be performed by any professional shop with a compatible high-end scan tool. It is only required if the light is on.
Is my original BCM returned to me?
No, we keep your original module as part of the service exchange. There is no core charge, and you receive a fully tested and programmed replacement ready for installation.
How can I be sure the BCM is my problem?
While the symptoms listed are strong indicators, a full diagnosis is always recommended. Common signs include multiple, unrelated electrical failures (lights, locks, windows) and communication error codes (U-codes) stored in the system.
