Restore Your GM Truck’s Electrical System
Are you battling bizarre electrical issues in your 2010 GMC Yukon XL 1500? Flickering lights, malfunctioning power windows, a dashboard that’s lit up with warning messages, or even a vehicle that refuses to start can all point to a single culprit: a failing Body Control Module (BCM). As the central nervous system for your vehicle’s electronics, when the BCM falters, it can create a cascade of frustrating and seemingly unrelated problems. This isn’t just an annoyance; it’s a critical component for your vehicle’s proper operation and safety.
This is a direct-fit replacement Body Control Module, part number 15837419, that arrives at your door fully programmed to your vehicle’s specific VIN. We handle the complex part, loading the latest GM factory software so you can avoid an expensive trip to the dealership. Simply provide your VIN after purchase, and we’ll ensure this module is ready for installation right out of the box, restoring function and peace of mind.
A Technician’s Notebook: The Case of the Spooky SUV
I remember a 2010 Yukon XL 1500 that came into my bay with a list of complaints that sounded like it was haunted. The owner said the dome lights would fade in and out while driving, the radio would randomly change stations, and the security light was always on. He’d already replaced the battery and checked the main grounds. My initial scan showed a dozen communication codes (U-codes) across various modules. Instead of chasing each one, I focused on the common link: the 2010 Yukon XL 1500 BCM. After confirming power and ground to the module were solid, we swapped in a pre-programmed BCM. Every single ghost in the machine vanished. It’s a classic example of how a single failing BCM can mimic multiple other problems, costing you time and money if not diagnosed correctly.
Common Signs of a Failing BCM
If your vehicle is experiencing these symptoms, a faulty Body Control Module is a likely cause. Don’t let electrical gremlins take over your truck.
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ The security system engaging randomly, causing a no-start condition.
- ✔ Warning lights on the dash, such as for the airbag or traction control system.
- ✔ Communication loss DTCs (Diagnostic Trouble Codes), particularly U-codes like U0140, U0155, or U0164.
- ✔ Horn or alarm sounding without reason.
Your Straightforward Installation Guide
Installing your new 2010 Yukon XL 1500 BCM is a manageable job for a confident DIYer or any professional mechanic. The module is typically located under the driver’s side of the dashboard, near the steering column.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to allow the systems to power down completely.
- Locate the BCM: On the Yukon XL, it’s usually mounted to a bracket under the steering column. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors. Most have a locking tab that needs to be depressed. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Seat the new, pre-programmed BCM onto the bracket and secure it. Reconnect all electrical connectors firmly until they click into place.
- Reconnect and Test: Reattach the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test functions like lights, windows, and locks to confirm operation.
- Perform Relearns: As noted in our post-install section, you may need a professional scan tool to perform an Airbag System Sync or Brake Pedal Position Relearn if related warning lights appear.

Post-Installation Procedures
While this module is programmed for plug-and-play functionality, some vehicle systems may require recalibration after installation:
- Airbag System Sync: If the airbag light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible high-level scan tool.
- Brake Pedal Position Relearn: On some models, this relearn procedure may be necessary to ensure correct brake light and traction control operation.
Disclaimer: Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
Frequently Asked Questions
Do I need to send my old BCM back?
No, there is absolutely no core charge for this part. You can keep your original module.
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship the module until we receive this information.
Is this a brand new part?
This is a high-quality, tested replacement part that has been programmed with the latest software from GM for your specific vehicle, ensuring reliable performance.
Will this fix my “Service StabiliTrak” message?
A failing BCM can certainly cause StabiliTrak or traction control warnings due to lost communication or bad sensor data. While it’s a very common solution, you should always have the vehicle properly diagnosed, as other issues can also trigger that message.
What tools are needed for the post-installation relearns?
Procedures like the Airbag System Sync require a professional-grade bidirectional diagnostic tool (like a GM Tech 2, MDI, or high-end Snap-on/Autel scanner). Many local repair shops can perform these services for you if needed.
