Restore Full Control Over Your Truck’s Electronics
Are you battling bizarre electrical issues in your GMC Yukon XL 2500? One minute the power windows work, the next they don’t. Maybe your HVAC controls have a mind of their own, or you’re staring at a persistent airbag light. These are classic signs of a failing Body Control Module (BCM), the electronic nerve center of your vehicle. This replacement BCM, part number 22860591, is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN. This eliminates the need for expensive dealership visits and gets your truck’s essential features working reliably again.
A Technician’s Notebook: The Case of the Haunted Sierra
A customer brought in a 2010 Sierra 2500 with a laundry list of complaints: intermittent radio, flickering dash lights, and a random no-start condition. The battery and alternator tested fine. After connecting my scanner, I saw multiple communication loss codes with the BCM. In my 20+ years of experience, I’ve learned that before condemning the module itself, you check its foundation. I found the main BCM ground point on the firewall was corroded. While cleaning the ground helped, the intermittent issues returned, indicating the voltage spikes from the bad ground had already damaged the BCM internally. Installing a VIN-programmed BCM like this one, and ensuring a clean ground connection, provided a permanent, reliable fix. The customer was back on the road the same day without a single recurring issue.
Is Your Yukon Showing These Electrical Gremlins?
- ✔ Power windows, door locks, or interior lights failing intermittently or completely.
- ✔ HVAC system not responding or blower motor working sporadically.
- ✔ An active airbag warning light on the dash, often with DTC B1001 stored.
- ✔ The security system preventing the engine from starting or causing stalling.
- ✔ A cluster of seemingly unrelated diagnostic trouble codes (DTCs) pointing to body systems.
- ✔ Wipers or exterior lights activating on their own or not working at all.
A Straightforward Guide to Installation
Getting your truck back to normal is easier than you think. This is a job most DIYers can handle in under 15 minutes with basic tools.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on electrical components.
- Locate the BCM: On most 2007-2011 Yukon XL 2500 models, the BCM is located under the driver’s side dashboard, to the left of the steering column.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old module. They have locking tabs, so be gentle. Once disconnected, unclip or unbolt the module from its mounting bracket.
- Install the New Module: Seat the new, pre-programmed BCM into the bracket and securely plug in all the electrical connectors. You should hear a click as they lock into place.
- Check Your Grounds: Based on my experience, I always recommend checking the main ground connections near the BCM for any signs of corrosion or looseness. A clean, tight ground is critical for the new module’s longevity.
- Reconnect and Test: Reconnect the battery terminal. Start the vehicle and test all functions: windows, locks, lights, wipers, and HVAC to confirm the repair.
Post-Installation Procedures & Notes
Our VIN programming handles the heavy lifting, but some GM vehicles require a final handshake between modules. If your airbag light remains on after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure using a professional scan tool. This syncs the new BCM with the airbag system. Additionally, some models may require a Brake Pedal Position Relearn. Best of all, there is no core charge, so you don’t have to worry about sending the old part back.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide range of non-engine-related functions. This includes power windows, door locks, the security system, interior and exterior lighting, wipers, and the HVAC system. When it fails, you experience the strange electrical issues this part is designed to fix.
Is this module really plug-and-play?
Yes. We program the module to your vehicle’s specific VIN before shipping. This means it’s ready for installation right out of the box, with no need for additional programming or flashing from a dealership, saving you significant time and money.
Why is my airbag light on after installing the new BCM?
This is a common security measure in GM vehicles. If the light is on, it means the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). This requires a professional scan tool to perform the “Setup SDM Primary Key in BCM” function, which is a quick procedure for any qualified technician.
Do I need to return my old part (core charge)?
No. We do not require a core return for this part. You can keep or dispose of your old module without any additional charges or hassle.
Where is the BCM located on my 2009 Yukon XL?
On the 2007-2011 GMC Yukon XL 2500 and similar GM platforms, the Body Control Module is typically found under the driver’s side of the dashboard, usually mounted to the left of the steering column. It’s accessible after removing the lower dash panel.
