Restore Full Functionality to Your GM Truck with a VIN-Programmed BCM
If you’re dealing with the frustrating and unpredictable electrical problems common in GM trucks and SUVs, you’ve come to the right place. As a technician with over two decades of experience, I’ve seen firsthand how a failing Body Control Module (BCM) can turn a reliable vehicle into a source of constant headaches. This isn’t just an inconvenience; it can affect everything from your climate control to your vehicle’s security system. This replacement BCM, part number 22860591, is the definitive solution for your 2007-2011 Yukon XL 2500 BCM and a wide range of other GM models, arriving pre-programmed to your vehicle’s VIN for a true plug-and-play fix.
A Technician’s Notebook: The Case of the Ghostly Glitches
I once had a 2009 Sierra 2500 in my bay with a laundry list of bizarre symptoms: the radio would cut out, the dome lights would flicker, and the driver’s side window only worked when it wanted to. The owner had already replaced the battery and checked fuses, but the problems persisted. After connecting my scanner, I saw multiple communication loss codes with the BCM. The module itself wasn’t completely dead, but it was failing intermittently. We installed a VIN-programmed BCM, and just as importantly, cleaned the main grounding point under the dash. The problems vanished instantly. It’s a classic failure on these platforms, and this module is the reliable fix that gets you back to a fully functional truck without the guesswork.
Is Your Truck Showing These Symptoms?
- ✔️ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔️ HVAC and climate control functions are unresponsive, or the blower motor works intermittently.
- ✔️ The security system acts up, causing no-start conditions or false alarms.
- ✔️ An airbag warning light is illuminated on the dash, often with a DTC B1001 (Setup SDM Primary Key in BCM).
- ✔️ Strange lighting issues, such as headlights, taillights, or interior lights staying on or not turning on.
- ✔️ Communication error codes (U-codes) stored in the system, indicating a network problem.
Ignoring these signs can lead to more significant issues down the road. This replacement Yukon XL 2500 BCM is engineered to OEM specifications to permanently resolve these electrical gremlins and restore the vehicle’s core functions. The most significant benefit is that we handle the programming for you. Simply provide your VIN during checkout, and the module arrives ready to install, saving you a costly trip to the dealership for calibration.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On most of these GM trucks and SUVs, the BCM is located under the driver’s side dashboard, near the steering column. You may need to remove a lower dash panel for access.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unclip or unbolt the old module from its mounting bracket.
- ✔ Install the New Module: Seat the new, pre-programmed BCM into the mounting bracket and securely plug in all the electrical connectors. You’ll hear a click as they lock into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—windows, locks, lights, wipers, and HVAC—to confirm the repair was successful.
- ✔ Post-Install Checks: In some cases, particularly if you had an airbag light, a ‘Setup SDM Primary Key’ or ‘Brake Pedal Position Relearn’ may be needed using a bi-directional scan tool. This syncs the new BCM with the other vehicle systems.

Frequently Asked Questions
Do I need to have a dealer program this BCM?
No. We pre-program the module to your vehicle’s specific VIN before shipping. This makes it a plug-and-play installation, saving you time and the high cost of dealership programming.
Why is my airbag light still on after installation?
If the airbag light was on before, you may need to perform a ‘Setup SDM Primary Key in BCM’ procedure with a professional-grade scan tool. This re-establishes communication between the new BCM and the airbag system.
What tools do I need for the installation?
Typically, you’ll only need basic hand tools like a socket set or a screwdriver to remove the lower dash panel. The module itself usually has simple clips or small bolts holding it in place.
Is there a core charge for my old part?
No, there is no core charge. You can keep or dispose of your old module without the hassle of sending it back.
Could something else be causing these electrical problems?
While the BCM is the most common culprit for these widespread issues, it’s always a good practice to check for bad grounds, damaged wiring, or a failing battery. In my experience, a poor ground connection is the second most likely cause.
