End the Electrical Chaos in Your GM Truck or SUV
Is your 2015 GMC Yukon suffering from bizarre electrical issues that you can’t seem to pin down? Flickering lights, unresponsive power windows, a horn that honks on its own, or a dashboard that lights up with random warnings are classic signs of a failing Body Control Module (BCM). As the central computer for your vehicle’s comfort and convenience features, a faulty BCM can make driving frustrating and unpredictable. This isn’t just an annoyance; it can affect systems tied to safety and security. Stop chasing symptoms and address the root cause with a reliable, straightforward solution.
We offer a professionally programmed BCM, part number 13594692, that eliminates the guesswork and the expensive trip to the dealership. Our service is simple: you send us your original BCM, we transfer all the critical vehicle-specific data to this replacement unit, and then we ship it back to you. The result is a true plug-and-play module tailored specifically for your vehicle. This is the most efficient way to restore full functionality to your truck or SUV.
A Technician’s Notebook: The Case of the Haunted Sierra
I once had a 2014 Sierra 1500 in my bay that was driving the owner crazy. The radio would randomly shut off, the dome lights would flicker while driving, and the key fob worked intermittently. He had already replaced the battery and checked fuses, but the problems persisted. A quick scan revealed a slew of communication error codes (U0140, U0155, etc.), all pointing back to a single culprit: the BCM. Instead of the costly and time-consuming process of ordering a new module from the dealer and booking programming time, we used this exact cloning service. The replacement 2015 Yukon BCM (which shares the same architecture) arrived programmed and ready. Within an hour, the truck was fully assembled and every single electrical gremlin was gone. This service turns a complex electronic nightmare into a simple parts swap.
Is Your Vehicle Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, your Body Control Module is the likely cause:
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ The security system or horn activating randomly.
- ✔ Key fob not being recognized or working intermittently.
- ✔ Dashboard warning lights for ABS, Airbag, or StabiliTrak appearing without a clear mechanical cause.
- ✔ Communication error codes, such as U0140 (Lost Communication With Body Control Module).
- ✔ The vehicle failing to start or crank despite a good battery and starter.
A Straightforward Guide to Installation
Installing your pre-programmed BCM is designed to be a simple process for a DIYer with basic tools. While the exact location can vary slightly, it’s typically found under the driver’s side dashboard.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before beginning work.
- Locate the BCM: On most GM trucks and SUVs like the 2015 Yukon, the BCM is located under the steering column, often behind a lower dash panel.
- Remove Trim Panels: Carefully remove any plastic trim or panels necessary to access the module.
- Disconnect and Remove: Unplug the multiple wiring harness connectors. They have locking tabs that must be pressed to release. Once disconnected, remove the bolts or nuts holding the BCM in its bracket.
- Install the Replacement: Mount your new, pre-programmed BCM in the same location and securely reconnect all wiring harnesses. You should hear a ‘click’ as they lock into place.
- Reassemble and Reconnect: Reinstall any trim panels you removed and reconnect the negative battery terminal.
- Test Functionality: Start the vehicle and test all body functions—lights, windows, locks, radio, etc.—to confirm the repair was successful.
Important Post-Installation Notes
While our cloning service handles the primary programming, some vehicle systems may require a relearn procedure after the BCM is replaced. This is a normal part of the vehicle’s security and safety protocols.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure proper brake light and traction control operation.
Disclaimer: Always consult a factory service manual or a qualified technician if you are unsure about any step. No core charge is required; you can keep your original module.

Frequently Asked Questions
How does the cloning service work?
After you place your order, we will provide instructions for you to ship your original BCM to us. Once we receive it, our technicians will extract the vehicle-specific data and flash it onto the replacement module. We then ship the plug-and-play replacement back to you.
Do I really not need to program this module?
Correct. Because we clone the data from your original unit, the replacement BCM will be pre-configured for your vehicle’s specific VIN and options. This eliminates the need for expensive programming with dealership tools.
Where is the BCM located on my 2015 Yukon?
On the 2015 GMC Yukon and similar GM platforms, the Body Control Module is typically mounted under the driver’s side dashboard, near the steering column.
What if my airbag light comes on after installation?
This is an expected possibility. It means the BCM needs to be synced with the airbag module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade scan tool to resolve this.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your original module back to us after you receive the replacement, though we need it initially for the cloning service.
