The Plug-and-Play Solution: A Pre-Programmed 2007-2011 Yukon XL BCM
The biggest hurdle in replacing a modern vehicle module is the need for expensive dealership programming. We eliminate that step entirely. Before this module ships, we program it to your vehicle’s specific Vehicle Identification Number (VIN). This ensures that it integrates seamlessly with your truck’s existing systems, just like the original part from the factory. There is no need for a trip to the dealer or a costly appointment with a specialized technician. Installation is straightforward and can typically be completed in under 15 minutes with basic hand tools. The BCM is located under the driver’s side dashboard, near the steering column.
Post-Installation Procedures
In some cases, minor relearn procedures may be necessary after installation. If the airbag light remains on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function to sync the new module with the airbag system. Additionally, a ‘Brake Pedal Position Relearn’ might be required to ensure proper brake light and traction control operation. These are standard procedures and are often not required for all vehicles.
Frequently Asked Questions
What does the Body Control Module do on my Yukon XL?
The BCM acts as the main computer for your vehicle’s comfort and convenience features. It controls the power windows, door locks, interior and exterior lighting, wipers, security system, and HVAC fan speeds, among other functions.
Is this module ready to install right out of the box?
Yes! This is the key benefit of our service. We pre-program the module to your vehicle’s VIN before shipping, making it a true plug-and-play solution. No additional programming is required.
