Are you battling persistent electrical gremlins in your GMC Yukon XL, Chevrolet Silverado, or Cadillac Escalade? A faulty Body Control Module (BCM) is often the culprit behind a host of frustrating issues, from flickering lights and non-responsive power windows to a dead HVAC system. This genuine OEM-quality BCM, part number 22860591, is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a true plug-and-play installation.
Common Symptoms of a Failing BCM
- ✔ Intermittent or total loss of HVAC controls and blower fan operation.
- ✔ Power windows, door locks, or interior/exterior lights working erratically or not at all.
- ✔ The security system malfunctioning, causing no-start conditions or false alarms.
- ✔ An illuminated airbag warning light, often accompanied by DTC B1001.
- ✔ Unexplained battery drain while the vehicle is parked.
- ✔ Instrument cluster gauges behaving erratically or going dark.
- ✔ Diagnostic trouble codes (DTCs) related to communication or body electronic systems.
Why Choose Our Programmed 2007-2011 Yukon XL BCM?
The BCM is the central nervous system for your vehicle’s body electronics. It doesn’t just turn things on and off; it communicates with other modules to ensure everything works in harmony. Our service eliminates the biggest headache of BCM replacement: the need for expensive dealership programming. We flash the module with the latest GM software and your vehicle’s unique VIN before it ships. This ensures that all factory-installed options work correctly right out of the box, saving you time, money, and a trip to the dealer.
Installation and Post-Install Procedures
Physically installing the BCM is straightforward. It is typically located under the driver’s side dashboard, near the steering column, and can be swapped in minutes. However, be aware of a few potential post-installation steps:
- Airbag System Sync: If the airbag light remains on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This re-establishes communication between the new BCM and the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control functionality.
This module is a direct replacement for a wide range of GM trucks and SUVs and is interchangeable with part numbers including 25844480, 25835966, 15943678, 20939137, and more. With no core charge, you can complete your repair without the hassle of returning the old part.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that controls and monitors many of your vehicle’s non-engine related functions. This includes power windows, door locks, the security system, interior and exterior lighting, wipers, and the HVAC climate control system.
Why is VIN programming necessary for this part?
VIN programming loads your vehicle’s specific configuration and software into the BCM. This ensures all features and options your truck or SUV came with from the factory work correctly. Without it, the module won’t function properly. Our pre-programming service makes it a plug-and-play part.
Is this BCM difficult to install myself?
The physical replacement is very simple, usually taking less than 15 minutes with basic tools. It’s located under the driver’s side dash. However, be aware that post-install procedures like an airbag system sync may require a professional-grade scan tool.
Will this fix my airbag light with code B1001?
A faulty BCM is a common cause of the B1001 code. Replacing the BCM will likely solve the root cause, but you will still need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a compatible scan tool to clear the code and turn off the light.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your old module, which saves you the time and expense of shipping it back.
