Is your GMC Yukon XL or other GM truck plagued by bizarre electrical problems? One moment the A/C works, the next it’s dead. The power windows have a mind of their own, and a persistent airbag light is on your dash. As a technician with over two decades of experience, I’ve seen these exact issues hundreds of times. The culprit is almost always a failing Body Control Module (BCM), the central command center for your vehicle’s comfort and convenience features.
Don’t let a faulty module sideline your truck. This OEM-quality Body Control Module, equivalent to part number 15901388, is the definitive solution. We take the hassle out of the repair by programming it to your vehicle’s specific VIN before we ship it. This means no expensive trips to the dealership for programming—it arrives ready for a simple, plug-and-play installation, restoring full functionality right out of the box.
Is Your Yukon Showing These Electrical Symptoms?
- ✔ Power windows, door locks, or interior/exterior lights operating intermittently or not at all.
- ✔ HVAC system failures, including a non-responsive blower motor or climate controls that won’t turn on.
- ✔ An active airbag warning light, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ Erratic security system behavior, which can lead to no-start conditions or random stalling.
- ✔ Communication errors with other modules, causing a variety of seemingly unrelated warning lights and DTCs.
- ✔ Poor ground symptoms that persist even after checking the ground connections.
A Technician’s Notebook: The Grounding Gremlin
I once had a 2009 Sierra in the bay with classic BCM failure symptoms—flickering lights and a dead radio. The owner had already replaced the battery and checked all the main grounds. Everything looked fine. After spending an hour chasing wires, we finally swapped in a known-good BCM. Instantly, every problem vanished. The original BCM had failed internally, creating what looked exactly like a bad ground. This is a common point of failure in these modules and can send even experienced mechanics on a wild goose chase. A new, pre-programmed BCM is often the fastest and most reliable fix.
A Straightforward Guide to BCM Installation
Getting your truck back to normal is easier than you think. The BCM is typically located under the driver’s side dashboard, near the steering column. The entire process usually takes less than 15 minutes.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronics.
- Locate the BCM: On your 2007-2011 Yukon XL, find the module under the dash. It will have several large multi-pin connectors attached to it.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once unplugged, unbolt or unclip the old module from its mounting bracket.
- Install the New Module: Seat the new, VIN-programmed BCM into the bracket and securely reconnect all electrical connectors. You should 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 functions: lights, wipers, windows, door locks, and the HVAC system.
Post-Installation Note: In some cases, particularly if you had an airbag light on, a simple relearn procedure may be needed. If the airbag light remains on after installation, a scan tool with GM-specific functions is required to perform the “Setup SDM Primary Key in BCM” procedure. Similarly, a Brake Pedal Position relearn might be necessary. These are simple steps for any professional shop or advanced DIYer with the right tool.

Frequently Asked Questions
What does ‘VIN Programmed’ mean for me?
It means this module is delivered to you ready for installation. We load your vehicle’s specific VIN and the latest GM software onto the BCM before shipping. This ensures all your vehicle’s options work correctly without requiring a trip to a mechanic or dealer for expensive programming.
Is this a difficult part for a DIYer to install?
Not at all. The physical installation is very simple, typically involving a few connectors and bolts under the dashboard. Since it’s pre-programmed, it’s one of the easiest module replacements you can do. The whole job can often be done in under 15 minutes.
Do I need to return my old BCM? Is there a core charge?
No. We do not require you to send back your old part, and there is absolutely no core charge. You can keep or dispose of your old module at your convenience.
My airbag light is on with code B1001. Will this fix it?
Yes, a faulty BCM is a very common cause of DTC B1001. Replacing it with our programmed module will resolve the root cause. However, after installation, you may need a capable scan tool to perform the ‘Setup SDM Primary Key’ function to sync the new BCM with the airbag system and clear the light.
Will this BCM work if my original part number is different?
Yes, this module is a direct replacement for numerous part numbers, including 15901388, 25835966, 15878753, 20939137, 22860591, and many others. It is designed to be a consolidated, reliable solution for the vehicles listed in our compatibility chart.
