Restore Full Electronic Functionality to Your GM Vehicle
Are you battling frustrating electrical gremlins in your 2010 GMC Yukon XL 1500? Issues like flickering lights, malfunctioning power windows and locks, or a security system that acts up on its own are often signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and intermittent problems. This replacement Body Control Module, part number 20864768, is the definitive solution to restore your vehicle’s systems to proper working order.
From the Diagnostic Bay
We had a 2010 Tahoe come in with a classic case of BCM failure. The customer complained of the interior dome lights staying on, which would drain the battery overnight. They’d already replaced the battery twice. A scan showed multiple communication errors with the BCM. Instead of a costly trip to the dealer for a new module and programming, we installed one of our VIN-programmed units. The installation was straightforward, and the electrical issues were resolved instantly. The customer was back on the road the same day, saving both time and money.
The Plug-and-Play Advantage: Pre-Programmed for Your Vehicle
Don’t waste time and money at the dealership. We take the hassle out of the replacement process. Simply provide us with your vehicle’s VIN (Vehicle Identification Number) during checkout, and our technicians will program this module with the latest GM software specific to your 2010 Yukon XL 1500. This ensures that the BCM communicates perfectly with your vehicle’s other computers right out of the box, making installation as simple as swapping the part. This is the most efficient way to get a replacement 2010 Yukon XL Body Control Module.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lighting behavior (flickering, staying on, or not turning on).
- ✔ Malfunctioning windshield wipers or washers.
- ✔ False alarms from the security system or key fob issues.
- ✔ Warning lights on the dashboard, such as the airbag or security light.
- ✔ Unexplained battery drain, leading to a no-start condition.
- ✔ HVAC (heating and air conditioning) controls not responding correctly.
Installation and Post-Install Considerations
Replacing the 2010 Yukon XL Body Control Module is typically straightforward. It is located under the steering column on the driver’s side. After disconnecting the battery, you can unbolt the old module, disconnect the wiring harnesses, and install the new one. While our programming handles the majority of the setup, some vehicles may require additional steps after installation:
- Airbag System Sync: If the airbag warning light illuminates after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure proper brake light and traction control operation.
We always recommend consulting a factory service manual or a qualified technician if you are unsure about any part of the installation process.
Frequently Asked Questions
What does a Body Control Module do?
The BCM acts as a central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, security system, and climate controls, ensuring all these convenience and safety features work together seamlessly.
How do I provide my VIN for programming?
After you complete your purchase, we will contact you for your vehicle’s 17-digit VIN. You can also add it to the notes section during checkout. We cannot ship your module until we have this information to perform the necessary programming.
Is this a direct replacement for my original BCM?
Yes. This module is a direct replacement for a wide range of original equipment part numbers, including 20864768, 25892622, 15921352, and many others listed in the description. It is designed to fit and function just like the original.
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 double-checking part numbers or for your own records.
What if my airbag light is on after I install the new BCM?
This is a known possibility. It means the new BCM needs to be electronically introduced to the vehicle’s Sensing and Diagnostic Module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional diagnostic tool to clear the light.
