Your Direct-Fit 2007-2011 Yukon XL 1500 BCM Solution
Don’t let a faulty module keep your truck off the road or force you into an expensive dealership visit. We take the guesswork out of the repair by programming this module with the latest GM software updates specifically for your vehicle. This ensures seamless integration and communication with your truck’s other electronic systems right out of the box. This module is the central command for your vehicle’s comfort, convenience, and security features, and installing a fresh, correctly programmed unit is the key to a lasting fix.
Common Symptoms of a Failing BCM:
- ✔ Unresponsive or erratic power windows, door locks, or interior/exterior lights.
- ✔ HVAC controls not working or blower motor operating intermittently.
- ✔ Airbag warning light illuminated on the dash, often with DTC B1001.
- ✔ Vehicle security system acting up, causing no-start conditions or false alarms.
- ✔ Intermittent stalling, misfires, or other strange electrical behavior.
- ✔ A variety of diagnostic trouble codes (DTCs) related to body systems.
Installation is straightforward for any DIY mechanic. The BCM is typically located under the driver’s side dashboard, near the steering column. While the physical swap takes minutes, please note that if your old BCM caused an airbag light, a post-installation ‘Setup SDM Primary Key’ procedure may be required using a professional scan tool to sync the systems. This module is a direct replacement for a wide range of part numbers, including 25823558, 25835966, 15943678, and 20939137.
Frequently Asked Questions
What does the Body Control Module do on my 2008 Yukon XL 1500?
The BCM is a computer that manages and controls a wide range of your vehicle’s non-engine related functions. This includes the power windows, door locks, security system, interior and exterior lighting, wipers, and the HVAC climate control system.
Will I need to have this BCM programmed by a dealership?
No. This module comes fully pre-programmed to your vehicle’s VIN. This allows for a simple plug-and-play installation without the need for expensive dealership programming tools or services.
Is this BCM difficult to install?
The physical installation is very simple, usually involving a few connectors and bolts under the driver’s side dash. It typically takes less than 15 minutes. However, if an airbag light is present, a scan tool procedure may be needed after installation to sync the new BCM with the airbag system.
What happens if I don’t replace a failing BCM?
Ignoring a failing BCM can lead to worsening electrical problems, unpredictable behavior of essential components like lights and locks, and could eventually result in a no-start condition if the security system is affected.
How do I know this is the correct part for my truck?
This module is compatible with a wide range of 2007-2013 GM trucks and SUVs. You can confirm fitment by matching the part number 25823558 (or any of the other listed interchangeable numbers) from your original module to the list on our product page.
What is the ‘Airbag System Sync’ procedure?
This is a one-time electronic handshake performed with a professional scan tool. It syncs the new BCM with the vehicle’s Sensing and Diagnostic Module (SDM), ensuring the airbag system is fully operational and turning off the warning light.
