Restore Full Functionality to Your GM Truck or SUV
Are you chasing down bizarre electrical issues in your 2007-2011 GMC Yukon? One moment the radio works, the next it doesn’t. The power windows have a mind of their own, and a persistent airbag light is on your dash. These frustrating, seemingly random problems often point to a single culprit: a failing Body Control Module (BCM). As the central computer for your vehicle’s comfort and convenience features, a faulty BCM can wreak havoc. This replacement module, equivalent to part number 15926094, arrives pre-programmed to your vehicle’s VIN, offering a direct and reliable solution to restore order to your truck’s electronics.
Case Study: The Ghost in the Machine
I had a 2008 Sierra in the bay last month with a laundry list of complaints from the owner. The dash lights would flicker, the door locks would cycle randomly while driving, and the HVAC blower was intermittent. The owner had already replaced the battery and checked the main fuses. After hooking up my scanner, I saw a dozen communication codes, including the notorious B1001 for a configuration error. Instead of diving into a complex wiring diagram, experience told me to check the BCM grounds first—they were solid. The next logical step was the BCM itself. After installing one of our VIN-programmed modules, every single issue vanished. It’s a reminder that what looks like multiple failures is often just one faulty central component.
Is Your Yukon Exhibiting These Electrical Gremlins?
A failing BCM doesn’t always cause a complete shutdown. It often starts with small, annoying glitches that grow worse over time. Here are the most common indicators I see in my shop:
- ✔ Unresponsive or erratic power windows, door locks, and interior/exterior lights.
- ✔ The security system acts up, sometimes preventing the vehicle from starting.
- ✔ An airbag warning light is illuminated on the dash, often with a DTC B1001 stored.
- ✔ HVAC controls are dead, or the blower motor works only on certain speeds or not at all.
- ✔ Strange warning messages on the driver information center (DIC).
- ✔ Communication loss codes with other modules on the vehicle network.
A Straightforward Guide to Installation
For the confident DIYer or professional mechanic, replacing the BCM is a quick job that saves you a trip to the dealership. Our pre-programmed module makes it a true plug-and-play repair.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: On most GM trucks and SUVs of this era, the BCM is located under the driver’s side of the dashboard, near the steering column. It’s a black box with several large multi-pin connectors.
- Swap the Module: Carefully unplug the electrical connectors from the old BCM. They have locking tabs, so be gentle. Unbolt or unclip the old module and secure the new one in its place.
- Reconnect and Test: Re-attach the electrical connectors firmly to the new BCM. Reconnect the battery terminal and start the vehicle. Test all functions: lights, locks, windows, wipers, and HVAC to confirm the repair.
- Post-Install Check: If the airbag light remains on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function. This syncs the new BCM with the airbag system. Some models may also require a Brake Pedal Position Relearn.

Frequently Asked Questions
Do I need to program this BCM at the dealership?
No. We pre-program the module to your vehicle’s specific VIN before shipping. It arrives ready for installation, saving you hundreds in dealership fees and programming time.
What is a core charge?
A core charge is a deposit you pay until you return your old part. We do not have a core charge on this BCM, so you can keep your old module without any hassle.
Will this fix my airbag light with code B1001?
This is the correct part to resolve that code, but after installation, the new BCM must be synced with the airbag system. This requires a professional scan tool with the ability to perform the ‘Setup SDM Primary Key in BCM’ procedure.
What tools are required for the installation?
Basic hand tools, like a socket set or nut driver, are all that’s typically needed to physically swap the module. However, as mentioned, a high-level diagnostic scanner may be required for post-installation procedures if certain warning lights appear.
Is this module covered by a warranty?
Yes, this BCM comes with a one-year warranty, giving you peace of mind and confidence in your repair.
