Restore Full Electrical Function to Your GM Truck or SUV
Are you chasing frustrating electrical gremlins in your GMC Yukon, Chevrolet Tahoe, or Silverado? Flickering lights, unresponsive power accessories, or a dashboard lit up with warning lights often point to a single culprit: a failing Body Control Module (BCM). This module acts as the central command center for your vehicle’s body electronics, and when it malfunctions, it can cause a cascade of confusing and disruptive issues. This genuine GM BCM, part number 22860591, is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a simple, direct-fit replacement that gets you back on the road without a trip to the dealer.
Is Your BCM Failing? Common Symptoms
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ HVAC controls that are unresponsive or a blower motor that works sporadically.
- ✔ An illuminated airbag warning light, often with DTC B1001.
- ✔ Malfunctioning interior or exterior lights (headlights, taillights, dome lights).
- ✔ Security system issues, including no-start conditions or random alarm activation.
- ✔ Communication errors with other modules on the vehicle’s network.

This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the hassle out of the repair by programming the module with your vehicle’s VIN before it ships. This crucial step ensures the BCM communicates flawlessly with your engine computer, transmission module, and security system right out of the box. By installing this pre-programmed 2007-2011 Yukon BCM, you restore the precise, original functionality your vehicle was built with, ensuring all electronic features operate as intended.
Installation and Post-Install Procedures
Physically replacing the BCM is straightforward. It is typically located under the driver’s side dashboard, near the steering column, and can be swapped in minutes. While the installation is simple, be aware of two potential post-installation steps that may require a professional-grade scan tool:
- Airbag System Sync: If the airbag warning light is on after installation (a common occurrence), the ‘Setup SDM Primary Key in BCM’ procedure must be performed. This syncs the new BCM with the airbag system to clear the light.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure proper brake light function and traction control system performance.
Best of all, there is no core charge for this module. You can keep your old part without the hassle of shipping it back.
Frequently Asked Questions
What does ‘VIN programmed’ mean for me?
It means we load your vehicle’s specific Vehicle Identification Number onto the module before shipping. This ensures it communicates perfectly with your truck’s other computers right out of the box, eliminating the need for an expensive trip to the dealership for programming.
Is this a difficult part to install myself?
The physical installation is very straightforward for most DIYers. It’s located under the driver’s side dash and held in by simple clips or bolts. The swap often takes less than 10 minutes. However, post-install procedures like the airbag system sync will require a professional scan tool.
Will this BCM fix my airbag light with code B1001?
A faulty BCM is a very common cause of the B1001 code. Replacing the module will resolve the root cause, but you will still need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a capable scan tool to clear the light and sync the new BCM with the airbag system.
What if I install it and some things still don’t work?
First, double-check that all connectors are fully seated. Second, verify the ground connection for the BCM is clean and tight, as poor grounds are a frequent cause of electrical issues in these trucks. If problems persist after confirming these, another issue may be present, but this module will have eliminated the BCM as the variable.
Is this compatible with my 2010 Chevrolet Silverado?
Yes, this BCM is compatible with a wide range of 2007-2013 GM trucks and SUVs, including the Silverado, Sierra, Tahoe, Suburban, Yukon, and Escalade. It directly interchanges with numerous part numbers like 25844480, 25835966, and 20939137.
