Restore Your Yukon’s Full Functionality and Eliminate Electrical Issues
Is your 2015 GMC Yukon experiencing a host of frustrating electrical problems? From power windows that won’t cooperate to a radio with a mind of its own, a failing Body Control Module (BCM) is often the culprit. As the central nervous system for your vehicle’s body electronics, its failure can cause widespread, intermittent issues that are a headache to diagnose. I’ve spent two decades in the shop, and I can tell you that a faulty BCM is one of the most common sources of these “ghost” problems in modern GM trucks and SUVs. This isn’t just an inconvenience; it can affect vehicle security and safety systems.
We offer a straightforward, reliable solution. This is a replacement BCM, part number 13506936, that comes ready for installation thanks to our professional cloning service. You simply send us your original BCM, and we transfer all the critical vehicle-specific data—including VIN, mileage, and key information—to this replacement unit. The result? A true plug-and-play module that eliminates the need for expensive dealership programming, saving you time and hundreds of dollars. Get your vehicle back to factory-fresh operation without the hassle.
From the Diagnostic Bay: The Case of the Unpredictable Sierra
A customer brought in a 2015 Sierra 1500 with a list of complaints that sounded like a prank: the dome lights would stay on, the driver’s side window would only go down, not up, and the remote start worked only half the time. He’d already replaced the battery and checked fuses. After hooking up the scan tool, we saw multiple U-series communication codes pointing to a network issue. Instead of chasing wires for hours, experience told me to check the BCM. We found evidence of water intrusion on the connector—a common failure point. A cloned BCM like this one had him back on the road in a day, with all systems go, for a fraction of the dealer’s quote.
Is Your GM Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights not working correctly (staying on or not turning on).
- ✔ The security system or keyless entry is malfunctioning.
- ✔ The radio or infotainment system behaves unpredictably.
- ✔ Dashboard warning lights appearing for seemingly unrelated systems.
- ✔ Communication DTCs (Diagnostic Trouble Codes) like U0140, U0155, or other U-series codes are present.
- ✔ A “Service Theft Deterrent System” message on the dash.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On most 2015 Yukon, Tahoe, and GM trucks, 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 from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket and remove it from the vehicle.
- ✔ Install the New BCM: Mount your new, pre-programmed BCM in the same location. Reconnect all electrical connectors, making sure they click securely into place.
- ✔ Reconnect Power: Reattach the negative battery terminal.
- ✔ Test and Verify: Start the vehicle and test all body functions—windows, locks, lights, radio, etc.—to confirm the repair. Note that some post-install procedures may be required (see FAQ).

Frequently Asked Questions about Your 2015 Yukon Body Control Module
How does the cloning service work?
How does the cloning service work?
It’s simple! After you place your order, we’ll provide instructions for shipping your original BCM to us. Once we receive it, our technicians will extract the unique programming and transfer it to the replacement module. We then ship the plug-and-play unit back to you, typically within 1-2 business days. This process ensures all your vehicle’s options and security data are retained.
Do I need to send my keys?
No, you do not need to send us your keys. All the necessary immobilizer and key data is stored within your original BCM and will be transferred during the cloning process. Your existing keys will work seamlessly with the new module upon installation.
Is there a core charge for my old BCM?
No, there is no core charge. We only need your original module to perform the programming service. Once the service is complete, you can keep your original module.
What if the airbag light comes on after installation?
In some cases, the new BCM may need to be synced with the airbag system’s Supplemental Deployment Module (SDM). If the airbag warning light is on, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a quick process for any qualified technician.
Will any other relearn procedures be needed?
Depending on your specific model, a Brake Pedal Position Sensor relearn might be necessary to ensure correct brake light and traction control operation. As always, consult a factory service manual or a qualified technician if you encounter any issues after installation. These procedures are standard for many electronic component replacements.
