Restore Your Yukon’s Electrical System with a Plug-and-Play BCM
Are you dealing with baffling electrical issues in your 2015 GMC Yukon XL 1500? Flickering lights, malfunctioning power windows, or a security system that has a mind of its own are classic signs of a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can cause a cascade of frustrating and seemingly unrelated problems. This service provides a straightforward, reliable solution by delivering a replacement BCM, part number 13594692 (interchangeable with 13591519), that is fully cloned from your original unit. This means no expensive dealership programming is required—it arrives ready for installation.

A Technician’s Notebook: The Phantom Drain Mystery
A customer brought in a 2015 Sierra with a classic “phantom drain” issue. The battery would be dead every few days. They had already replaced the battery and alternator. Diagnostics showed no obvious shorts. While monitoring the vehicle’s modules, I noticed the BCM wasn’t allowing other modules to go into ‘sleep mode’ after the ignition was off. It was keeping the network awake, slowly draining the battery overnight. A new, unprogrammed BCM would require a dealer visit, but our cloning service allowed the customer to get a direct replacement. After a simple swap, the truck’s electrical system behaved perfectly, and the battery drain was gone. It’s a textbook example of how a failing 2015 Yukon XL 1500 BCM can cause symptoms that point elsewhere.
Common Signs of a Failing BCM
If you’re experiencing any of the following, your BCM is the likely culprit. This part is a direct solution for these common headaches:
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors behaving unpredictably.
- ✔ Security system or keyless entry malfunctions, including alarm going off randomly.
- ✔ Wipers or radio turning on and off by themselves.
- ✔ False warning messages on the instrument cluster.
- ✔ Communication failure codes, often starting with ‘U’ (e.g., U0140), indicating the BCM is not communicating on the CAN bus network.
A Straightforward Guide to Installation
Installing your programmed 2015 Yukon XL 1500 BCM is a manageable task for a DIY enthusiast. The BCM is typically located under the steering column on the driver’s side.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Access the BCM: Remove any lower dash panels necessary to gain clear access to the Body Control Module. It’s often secured with a few small bolts or clips.
- Disconnect the Connectors: Carefully unplug the wiring harnesses from the old BCM. Pay attention to the locking tabs on each connector to avoid damage.
- Install the New BCM: Mount the replacement module in the same location and securely reconnect all wiring harnesses.
- Final Steps: Reinstall the dash panels and reconnect the negative battery terminal. Start the vehicle to confirm that the electrical issues are resolved.
Important Post-Installation Note: In some cases, additional vehicle-specific relearn procedures may be necessary. For instance, if your airbag warning light is on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. A ‘Brake Pedal Position Relearn’ may also be required. Always consult a factory service manual for your specific model.

Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. The entire point of our service is to handle the programming for you. We clone the data from your original module, so the replacement BCM is plug-and-play right out of the box, saving you from expensive dealer fees.
What data is transferred during the cloning process?
We transfer all vehicle-specific information, including the VIN, mileage, key fob programming, and other settings unique to your vehicle’s options. This ensures seamless integration and functionality.
What happens if I install it and the airbag light comes on?
This is a known possibility. It means the new BCM needs to be synchronized with the airbag system’s Sensing and Diagnostic Module (SDM). A professional mechanic with a high-end diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is there a core charge for this part?
No, there is no core charge. However, the service requires you to send us your original module so we can perform the data transfer to the replacement unit.
How do I find the part number on my original BCM?
The part number is printed on a sticker directly on the BCM’s housing. You will need to access the module, typically located under the driver’s side dashboard, to read the number on the label.
