Restore Your Vehicle’s Electrical System and End the Frustration
Is your 2015 GMC Yukon or another GM vehicle suffering from bizarre electrical issues? One moment the power windows work, the next they don’t. Perhaps the dashboard lights flicker randomly, or the security system prevents the engine from starting. These frustrating, hard-to-diagnose problems often point to one culprit: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, managing everything from interior lighting and power locks to security and accessory functions. When it fails, it can create chaos.
Instead of facing a costly trip to the dealership for a new module and expensive programming fees, we offer a streamlined, reliable solution. This listing is for a replacement BCM that comes fully programmed with your vehicle’s specific data. The process is simple: after your purchase, you ship us your original BCM. Our expert technicians will then clone all the essential information—including VIN, mileage, and key data—onto this replacement unit. We ship it back to you, ready for a true plug-and-play installation. This service ensures perfect compatibility and function, getting you back on the road without the dealership hassle.
A Technician’s Notebook
I remember a 2015 Sierra 1500 that came into the shop with a laundry list of complaints from the owner. The radio would turn off, the driver’s side window would get stuck, and occasionally the truck wouldn’t start, showing a ‘Service Theft Deterrent System’ message. The owner had already replaced the battery and checked fuses. After hooking up the scan tool, I saw multiple U-codes (communication errors) pointing toward the BCM. Instead of just replacing it, we confirmed power and ground were good at the module. The intermittent nature of the problem was a classic sign of internal BCM failure. By providing a cloned 2015 Yukon BCM equivalent, we saved the customer over $500 compared to the dealership quote and had him back on the road the next day.
Common Signs of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior dome lights or exterior lamps staying on or not turning on.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ The security or anti-theft system light is illuminated, causing a no-start condition.
- ✔ Multiple unrelated warning lights appearing on the instrument cluster.
- ✔ Diagnostic trouble codes (DTCs) related to communication loss, such as U0140, U0155, or other U-codes.
- ✔ Wipers activating on their own or not responding to the switch.
A Straightforward Guide to Installation
- ✔ 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 compatible trucks and SUVs like the 2015 Yukon, 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 original BCM. Note their orientation. Then, unbolt or unclip the module from its mounting bracket.
- ✔ Install the Replacement: Mount the new, programmed BCM in the same location. Securely reconnect all electrical connectors into their correct ports.
- ✔ Reconnect Power: Reattach the negative battery terminal.
- ✔ Test Functions: Start the vehicle and test all body functions—windows, locks, lights, wipers, etc.—to confirm the repair was successful.
Important Post-Installation Note: In some cases, additional steps may be needed. If your airbag light is on, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. Similarly, a ‘Brake Pedal Position Relearn’ may be necessary. These are not always required but are important to be aware of. No core charge is required; you can keep your original module.

Please verify your part number or consult the detailed fitment list to ensure compatibility. A properly functioning 2015 Yukon BCM is essential for vehicle operation.
What exactly is a ‘cloning’ service?
Cloning is the process where we extract the critical vehicle-specific software and security data from your original BCM and transfer it directly to the replacement module. This makes the new part an identical twin to your old one, ensuring it works seamlessly with your vehicle’s other computers without needing any additional programming.
Do I need to take my vehicle to a dealer after installation?
No. Because we pre-program the module with your vehicle’s data, you can avoid the dealership entirely. The unit arrives ready to install. In rare cases, a relearn procedure for the airbag or brake pedal sensor may be needed, which can be done by most independent repair shops.
Where is the BCM located on my 2015 Yukon?
On the 2015 GMC Yukon and similar GM trucks/SUVs, the Body Control Module is typically found under the driver’s side dashboard, attached near the steering column or on the firewall.
What is the turnaround time for the programming service?
We pride ourselves on a fast turnaround. Once we receive your original BCM, we typically program and ship the replacement unit back to you within 1-2 business days. We will provide you with tracking information as soon as it ships.
My original part number isn’t listed, but my vehicle is. Will this work?
This module replaces several part numbers. The most important thing is to match your original part number to one of the compatible numbers listed (13594692, 13594768, 13593214, 13580690, 13591519, 13594769). If you’re unsure, please contact us with your VIN and original part number before ordering.
