Tired of Electrical Gremlins? Restore Your GM Vehicle’s Functionality Today.
As a technician with over two decades of experience under the hood, I’ve seen it all. When a customer comes in with a 2015 GMC Yukon or a similar GM truck complaining about flickering lights, power windows with a mind of their own, or a security light that won’t turn off, my first suspect is often the 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 possessed. This isn’t just an annoyance; it can lead to dead batteries and unpredictable behavior on the road.
Forget the expensive trip to the dealership and the hassle of programming a new module from scratch. We offer a simple, reliable solution: a professionally programmed 2015 Yukon BCM that is a direct replacement for part number 13594768 and other compatible numbers. Our unique cloning service makes this repair truly plug-and-play.
How Our Simple Cloning Service Works
The process is straightforward. After you place your order, we’ll contact you with instructions to ship your original BCM to our facility. Once we receive it, our expert technicians will transfer all the critical data—including your vehicle’s specific options, key information, and security settings—to this replacement module. We then ship the ready-to-install BCM back to you. This means no additional programming, no security relearn procedures, and no surprise compatibility issues. It’s the most efficient way to get your vehicle back to 100%.
A Technician’s Notebook: The Case of the Erratic Escalade
I remember a 2015 Escalade that came into the shop with a laundry list of bizarre symptoms. The radio would randomly shut off, the dome lights would stay on, and the owner reported the alarm going off for no reason. After checking the battery and grounds, my diagnostic scanner kept losing communication with the BCM (a classic U0140 code). Instead of a costly new module and hours of programming at the dealer, we used a cloned BCM. The customer sent us their old module, we transferred the data, and they installed the replacement in their driveway. The problems vanished instantly—a perfect, cost-effective fix.
Common Signs of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ The security system acting up, preventing the vehicle from starting (anti-theft light on).
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Diagnostic trouble codes (DTCs) related to communication, such as U0140, U0155, or other U-codes.
- ✔ Parasitic battery drain causing a dead battery overnight.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- ✔ Locate the BCM: On most compatible models like the 2015 Yukon, Tahoe, and Silverado/Sierra, 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 the Connectors: Carefully unplug all the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Do not force them.
- ✔ Remove the Old Module: Unbolt or unclip the original BCM from its mounting bracket and remove it from the vehicle.
- ✔ Install the New BCM: Mount your new, programmed BCM in the same location and securely reconnect all the electrical connectors.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all functions: lights, windows, locks, radio, etc., to confirm the repair.
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 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 your brake lights and traction control system function correctly.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual or consult with a qualified mechanic if you are unsure about any step.

Frequently Asked Questions
What does ‘cloning’ mean for a BCM?
Cloning is the process of reading all the essential software and vehicle-specific data from your original BCM and writing it directly onto the replacement module. This ensures the new BCM is an exact digital copy, retaining your key programming, mileage, and factory-installed options for a true plug-and-play installation.
Do I have to send my original BCM to you?
Yes. To perform the cloning service and guarantee a plug-and-play solution, we need your original module to extract its data. We will contact you with shipping instructions after your purchase.
Will my existing keys and remote fobs work?
Absolutely. Because we clone your original data, the replacement BCM will recognize your existing keys and remotes immediately. No need for a costly locksmith or dealer visit for key reprogramming.
Is there a core charge for this part?
No, there is no core charge. You are not required to return your original module to us after the service is complete, though we do need it initially for the data transfer.
What if the airbag light comes on after I install it?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag’s Supplemental Deployment Module (SDM). A repair shop with a professional-grade diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
