Is your 2007-2011 GMC Yukon XL 2500 experiencing bizarre electrical issues?
Unresponsive power windows, a climate control system with a mind of its own, or random warning lights can be incredibly frustrating. These are hallmark symptoms of a failing Body Control Module (BCM), the central command center for your truck’s body electronics. When the BCM malfunctions, it disrupts communication between essential systems, leading to a cascade of problems. This genuine GM 25844480 BCM is the definitive, plug-and-play solution to restore your vehicle’s functionality and peace of mind.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional HVAC controls and blower motor operation.
- ✔ Illuminated airbag warning light, frequently accompanied by DTC B1001.
- ✔ Intermittent or total failure of power windows, door locks, and interior/exterior lighting.
- ✔ Security system malfunctions, leading to no-start conditions or false alarms.
- ✔ A variety of seemingly unrelated diagnostic trouble codes (DTCs) related to body systems.
- ✔ Stalling, misfires, or poor grounding signals that are difficult to trace.

Installation and Post-Install Procedures
Physical installation is straightforward for most DIY mechanics. The BCM is located under the driver-side dashboard near the steering column and can typically be swapped in less than 10 minutes. While the module is plug-and-play for most features, be aware of two potential post-installation steps:
- Airbag System Sync: If the airbag light is on after installation, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control function.
Frequently Asked Questions
What does ‘VIN Programmed’ mean for my Yukon?
It means we load your vehicle’s unique Vehicle Identification Number (VIN) and corresponding software onto the BCM before shipping. This makes the module recognize your truck’s specific features and security system, allowing for a plug-and-play installation without needing dealer tools.
Do I need to take my truck to a dealer after installing this?
In most cases, no. The VIN programming handles the critical setup. The only exception is if the airbag light comes on, which requires a special function on a professional scan tool to sync the BCM with the airbag module (SDM).
Where is the BCM located on my 2008 Yukon XL 2500?
The Body Control Module is typically found under the driver’s side of the dashboard, often attached to a bracket near the steering column or the firewall.
Will this BCM fix my airbag light with code B1001?
A faulty BCM is a very common cause of the B1001 ‘Option Configuration Error’ code. While not a guarantee for every case, replacing the BCM with a correctly programmed unit is the standard and most effective repair for this issue.
Is this part compatible with my old part number 25823559?
Yes. This module, 25844480, is a direct, interchangeable replacement for part number 25823559 and many others. It contains the latest hardware and software updates from GM.
