Restore Full Functionality to Your 2010 Yukon XL 1500
Are you dealing with baffling electrical issues in your GMC Yukon XL? One moment the power windows work, the next they don’t. Perhaps the radio is acting possessed, or you’re seeing strange warning lights flash across the dash. These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your truck’s body electronics, and when it starts to fail, it can create a cascade of frustrating and unpredictable problems. This isn’t a part you can afford to ignore.
We offer a reliable and straightforward solution. This is a direct-replacement Body Control Module, part number 20864768, for your 2010 Yukon XL 1500 Body Control Module. The best part? We handle the complicated part for you. Simply provide your vehicle’s VIN during checkout, and our technicians will program the module with the latest GM software specifically for your truck. It arrives at your door ready for installation, saving you a costly trip to the dealership and the hassle of finding a shop with the right programming equipment.
A Technician’s Notebook: The Case of the Haunted SUV
A customer brought in their 2010 Yukon XL complaining of “electrical gremlins.” The interior lights would flicker, the security light stayed on intermittently preventing it from starting, and the driver’s side power lock was dead. They had already replaced the battery and checked the main fuses, with no luck. In my 20+ years in the bay, these scattered, unrelated symptoms almost always point to one culprit. We hooked up the scanner and found multiple U-codes (U0140, U0155) indicating a loss of communication between the BCM and other modules. The BCM wasn’t just failing; it was taking the whole communication network down with it. A new, properly programmed BCM solved every single issue at once. It’s a perfect example of how this single component is the key to restoring order.
Is Your GM Vehicle Showing These Symptoms?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, a failing module is the likely cause:
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system light flashing, leading to a no-start condition.
- ✔ Erratic behavior from the radio, climate control, or dashboard gauges.
- ✔ False warning messages on the driver information center (e.g., “Service Stabilitrak”).
- ✔ Diagnostic Trouble Codes (DTCs) related to communication errors, such as U0140.
Your Straightforward BCM Installation Guide
Installing your new 2010 Yukon XL 1500 Body Control Module is a manageable task for a confident DIYer. While the exact location can vary slightly, in the Yukon XL it is typically found under the driver’s side dash, near the steering column.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait 10-15 minutes to allow all systems to discharge.
- Locate the BCM: On your Yukon XL, you’ll likely need to remove the lower dash panel beneath the steering wheel to gain access. The BCM is a black plastic box with multiple large electrical connectors.
- Disconnect and Remove: Carefully unplug all wiring harnesses from the old BCM. They have release tabs that need to be pressed. Once disconnected, unbolt the module from its mounting bracket and remove it from the vehicle.
- Install the New Module: Mount your new, pre-programmed BCM onto the bracket and securely plug in all the wiring harnesses. You should hear a ‘click’ as they lock into place.
- Reconnect and Test: Reinstall any trim panels you removed. Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test all body functions: lights, locks, windows, radio, etc.
Post-Installation Note: In some cases, additional vehicle-specific relearn procedures may be needed. For instance, if your airbag light is on, a professional scan tool is required for the “Setup SDM Primary Key in BCM” procedure. A Brake Pedal Position relearn may also be necessary. Always consult a service manual for your specific vehicle.

The Body Control Module acts as the brain for your vehicle’s electronic accessories. It controls non-engine related functions like power windows, locks, lights, security system, wipers, and the climate control system.
Yes. We program the module to your vehicle’s specific VIN before shipping. This ensures it communicates correctly with your truck’s other systems, making the installation process much simpler than buying a blank module.
Your Vehicle Identification Number (VIN) allows us to access the exact factory software and calibration files for your specific vehicle options. This ensures perfect compatibility and function.
No. There is no core charge for this part. You can keep your original module.
This can happen occasionally. It means the new BCM needs to be electronically ‘introduced’ to the airbag’s computer (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems.
