Is Your 2015 Yukon XL Suffering from Bizarre Electrical Gremlins?
The Body Control Module (BCM) is the central command center for your vehicle’s body electronics. It manages everything from your power windows and door locks to the interior lights, security system, and even communicates with other critical modules. When the BCM begins to fail, it can create a cascade of confusing and frustrating symptoms that seem unrelated. If you’re experiencing unpredictable electrical issues, a faulty BCM is often the culprit.
We had a 2015 Sierra in the shop last month with a classic case of BCM failure. The owner had already replaced the driver’s side window switch twice, convinced it was faulty because the window would only work intermittently. The horn would also chirp randomly when locking the doors. After hooking up our diagnostic scanner, we saw multiple communication fault codes (U-codes) pointing to the BCM. Instead of a complex and expensive dealer repair, we performed a cloning service just like this one. The customer installed the new module in his driveway, and all the strange electrical issues were gone instantly. It saved him hundreds in diagnostic and programming fees.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system acting up, causing no-start conditions or a “Service Theft Deterrent System” message.
- ✔ The horn sounding randomly or not working when pressed.
- ✔ Wipers activating on their own or not responding to the switch.
- ✔ Multiple, unrelated warning lights appearing on the dashboard.
- ✔ Key fobs failing to lock or unlock the doors consistently.
Your Plug-and-Play Solution: The 2015 Yukon XL BCM Cloning Service
Forget expensive dealership visits and the hassle of programming a new module from scratch. Our professional cloning service provides a simple, direct-fit solution. We transfer the essential data—including your vehicle’s VIN, key information, and specific options—from your original BCM to this replacement unit. The result is a fully functional module that is 100% plug-and-play. No additional programming or calibration is required for the BCM itself.
How The Process Works:
- ✔ Place Your Order: Complete your purchase through our secure checkout.
- ✔ We’ll Contact You: We will reach out with simple instructions and the address to ship your original BCM to us.
- ✔ Ship Your Module: Send us your original BCM.
Important Post-Installation Information
While the BCM itself is plug-and-play, some related systems may require a simple sync procedure after installation. These are not always necessary but are important to be aware of:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a “Setup SDM Primary Key in BCM” procedure must be performed with a professional-grade scan tool. This syncs the new BCM with the airbag module.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation and traction control function.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.

Frequently Asked Questions
What is a BCM cloning service?
Cloning is the process of reading the critical vehicle-specific data (like VIN, mileage, and key programming) from your original BCM and writing it onto a replacement module. This makes the replacement unit an exact electronic match to your original, allowing for a simple plug-and-play installation without the need for dealer programming.
Why do I need to send my original BCM?
Your original BCM contains the unique data that is essential for your vehicle to function correctly. By sending it to us, you ensure we can create a perfect clone, which guarantees compatibility and prevents the need for expensive and complicated programming procedures at a dealership.
Is this module difficult to install?
The physical installation is straightforward for someone with basic mechanical skills. The BCM is typically located under the steering column or behind the driver’s side dash. It involves disconnecting the battery, removing a few trim panels, and unplugging the electrical connectors. The main benefit of our service is that the electronic part—the programming—is already done for you.
What happens after I place my order?
Once your order is confirmed, we will contact you via the information you provided at checkout with detailed instructions on how and where to ship your original module. Please ensure your contact information is correct.
Will I need to get my keys reprogrammed?
No. Because we are cloning all the data from your original module, the replacement BCM will already recognize your existing keys. This is a major benefit of our service and saves you a significant amount of money and time.
What if the airbag light comes on after installation?
This is a known possibility. It simply means the new BCM needs to be electronically ‘introduced’ to the airbag module (SDM). A repair shop with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
