If you’re dealing with bizarre electrical issues in your 2010 GMC Yukon XL 1500, you’ve come to the right place. As a technician with over two decades of experience under the hood, I’ve seen firsthand how a failing Body Control Module (BCM) can turn a reliable SUV into a source of constant frustration. It’s the central hub for your vehicle’s electronics, and when it goes bad, it can cause a cascade of problems that seem unrelated. This isn’t just a part; it’s the solution to getting your truck’s brain working correctly again.
We offer a dependable, direct-fit replacement Body Control Module, specifically part number 15819552. The best part? We handle the programming for you. Simply provide your vehicle’s VIN during checkout, and we’ll flash the module with the latest GM software updates specific to your Yukon. This means no expensive trip to the dealership for programming—saving you time, money, and a major headache. You get a component that is ready for installation right out of the box.
From the Diagnostic Bay: The Case of the Haunted Yukon
A customer brought in a 2010 Yukon XL 1500 with a laundry list of complaints: the radio would turn on and off by itself, the interior dome lights would flicker while driving, and occasionally, the power locks would stop responding. He’d already replaced the battery and checked the main fuses. After connecting my scan tool, I found several communication error codes (U-codes) pointing to a network issue. In my experience, when multiple, unrelated electronic systems act up simultaneously, the BCM is the primary suspect. We swapped in a pre-programmed BCM, and within an hour, every single ghost in his machine was gone. This is a classic BCM failure scenario.
Is Your Yukon Showing These BCM Failure Signs?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your BCM needs replacement:
- ✔ Power windows, mirrors, or door locks operating intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system acting erratically, preventing the vehicle from starting (anti-theft light on).
- ✔ False warning lights on the dashboard, such as the airbag or ABS light.
- ✔ Communication error codes stored, particularly U-codes like U0140, U0155, or U0164.
- ✔ Wipers behaving unpredictably or not parking in the correct position.
- ✔ The horn sounding randomly or not working when pressed.
Your Straightforward BCM Installation Guide
Replacing the BCM on your Yukon is a manageable job for a DIYer with basic tools. 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 about 10-15 minutes to allow all systems to discharge completely.
- Locate the BCM: On the 2010 Yukon XL 1500, the BCM is found under 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.
- Install the New Module: Mount your new, pre-programmed BCM in the same location. Reconnect all electrical connectors firmly, ensuring 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 the functions: power locks, windows, lights, and wipers.
Important Post-Installation Steps
While our programming handles the heavy lifting, some vehicle systems may need to be re-synced after the new BCM is installed. This is normal. Please be aware of the following potential procedures:
- ✔ Airbag System Sync: If your 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: Some models may require a brake pedal position sensor relearn to ensure proper operation of the brake lights and stability control systems.
Disclaimer: Procedures can vary. Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.

Frequently Asked Questions
Frequently Asked Questions
How does the VIN programming work?
After you place your order, you will need to provide us with your 17-digit Vehicle Identification Number (VIN). We use this to load the exact, most current GM-approved software for your specific vehicle onto the BCM before we ship it.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your original module, which can be helpful for comparison or as a backup.
Is this a plug-and-play part?
For the vast majority of functions, yes. Because we pre-program it to your VIN, it eliminates the need for dealer-level programming. However, as noted above, certain systems like the airbag (SRS) or brake sensor may require a simple relearn procedure with a compatible scan tool.
What tools do I need for installation?
Basic hand tools are usually all that’s required: a socket set to disconnect the battery and remove any mounting bolts, and possibly a trim removal tool to safely pry off dash panels without scratching them.
Will this fix my ‘Service StabiliTrak’ message?
It can, but it’s not guaranteed. While a faulty BCM can cause StabiliTrak errors due to bad data from sensors like the brake pedal position sensor, the message can also be triggered by wheel speed sensors, the steering angle sensor, or other components. A proper diagnosis is always recommended.
What if I install it and still have problems?
If issues persist, it’s possible there is another fault in the vehicle, such as a wiring problem or a different failed module. Double-check all connections first. Our team of experts is also here to help guide you through diagnostic possibilities.
