Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your GMC Yukon XL 2500? Intermittent power windows, a malfunctioning HVAC system, or random warning lights can often be traced back to a single component: a failing Body Control Module (BCM). This essential electronic unit acts as the central hub for your vehicle’s body electronics. When it fails, it can cause a cascade of confusing and disruptive issues. This genuine OEM-quality replacement BCM, part number 25971916, is the definitive solution to restore your vehicle’s systems to factory-perfect operation.
Is Your Vehicle Showing Signs of BCM Failure?
A failing BCM doesn’t always present as a total shutdown. Often, the symptoms start small and become progressively worse. If you’re experiencing any of the following, your BCM is the likely culprit:
- ✔ Unresponsive or erratic power windows, door locks, or interior/exterior lights.
- ✔ HVAC controls that don’t work or a blower motor that operates intermittently.
- ✔ An illuminated airbag warning light, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ Security system malfunctions, including no-start conditions or random alarm activation.
- ✔ Unexplained engine performance issues like stalling or misfires due to incorrect security signals.
- ✔ A variety of communication-related DTCs stored in the vehicle’s memory.
The Plug-and-Play Solution: A Pre-Programmed 2007-2011 Yukon XL 2500 BCM
Replacing a BCM used to mean a costly trip to the dealership for installation and programming. Our modules eliminate that step entirely. We pre-program this BCM to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This ensures that it communicates flawlessly with your truck’s existing electronic systems right out of the box. This VIN-specific programming loads the latest GM software updates, ensuring optimal performance and resolving many common software-related DTCs without any further setup required.
Installation and Post-Install Considerations
Installation is straightforward for those with basic mechanical skills. The BCM is typically located under the driver’s side dashboard, near the steering column, and can be swapped in minutes. However, please be aware of potential post-installation procedures:
- Airbag System Sync: If the airbag warning light is on after installation, a procedure called ‘Setup SDM Primary Key in BCM’ must be performed. This requires a professional-grade scan tool and syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper brake light and traction control operation. This is also performed with a scan tool.
This module comes with a one-year warranty and requires no core return. You can keep your old part without the hassle of shipping it back or paying a core charge.
