Restore Your GM Truck’s Electrical System with a Plug-and-Play BCM
Are you chasing electrical gremlins in your 2010 GMC Yukon XL 1500? Flickering lights, malfunctioning power windows, a security system that acts possessed, or a dashboard lit up with random warnings are all classic signs of a failing Body Control Module (BCM). As the central nervous system for your vehicle’s electronics, when the BCM goes down, it can cause a cascade of frustrating and seemingly unrelated problems. This isn’t just an annoyance; it’s a reliability issue that can leave you stranded. Stop the guesswork and replace the faulty unit with a dependable, pre-programmed solution.
This is a direct-fit replacement Body Control Module for your vehicle, delivered to your door already programmed with the latest GM software updates. We handle the complex part for you. Simply provide your vehicle’s VIN during checkout, and our technicians will flash the module specifically for your truck’s configuration. This eliminates the need for an expensive trip to the dealership for programming, saving you both time and money. Get your Yukon, Tahoe, or Escalade back to factory-fresh operation with a reliable BCM that’s ready to install right out of the box.
A Technician’s Notebook: The Case of the Haunted SUV
A customer brought in a 2010 Yukon XL with a laundry list of bizarre complaints. The radio would turn on and off by itself, the driver’s side power window wouldn’t work but the passenger’s did, and the anti-theft light would flash, sometimes preventing it from starting. They’d already replaced the battery and checked fuses. In my shop, I’ve seen this exact scenario hundreds of times. After hooking up the scan tool, I found multiple U-codes (U0140, U0155) indicating a loss of communication with the BCM. A quick check of the power and ground circuits to the BCM confirmed they were solid. The module itself was the culprit. A pre-programmed 2010 Yukon XL Body Control Module had the truck fixed and back to the customer the same day, saving them from a multi-day wait and a hefty bill from the dealer.
Is Your Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system or keyless entry failing to operate correctly.
- ✔ A vehicle that won’t start, accompanied by a flashing security light.
- ✔ False warnings on the instrument cluster (e.g., “Service StabiliTrak,” “Service Airbag”).
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0140, U0100, or B1001.
- ✔ Unpredictable behavior of the radio or climate control systems.
Your Straightforward BCM Installation Guide
Installing your new 2010 Yukon XL Body Control Module is a manageable job for a confident DIYer. While the exact location can vary slightly, it’s typically found under the driver’s side dashboard, near the steering column.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Locate the BCM: On most GMT900 platform trucks like the Yukon, Tahoe, and Suburban, the BCM is mounted to a bracket under the driver-side dash, to the left of the steering column. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors. Most have a locking tab that needs to be depressed or a lever that needs to be swung over. Once disconnected, unbolt or unclip the old module from its mounting bracket.
- Install the New Module: Seat the new, pre-programmed BCM into the bracket and secure it. Reconnect all electrical connectors, ensuring they click firmly into place.
- Reconnect Power: Reattach the negative battery terminal.
- Perform Relearn Procedures: Start the vehicle. As noted in our post-installation requirements, you may need a capable scan tool to perform a “Setup SDM Primary Key in BCM” if the airbag light is on, or a “Brake Pedal Position Relearn.” This is not always required but is a possibility.

Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We program the module to your vehicle’s specific VIN before we ship it. It arrives ready for installation, saving you the time, hassle, and cost of a dealership visit.
Is there a core charge for my old part?
Absolutely not. There is no core charge on this BCM. You can keep your old module or dispose of it responsibly.
What tools are needed for the post-installation procedures?
If your vehicle requires the Airbag System Sync or Brake Pedal Position Relearn, these procedures must be completed with a professional-grade bidirectional diagnostic scan tool. Many advanced DIY and all professional-level scanners have this capability.
Where is the BCM located on my 2010 Yukon XL?
The Body Control Module is typically located under the driver’s side of the dashboard, to the left of the steering column. You will likely need to remove the lower dash trim panel to access it.
What happens if I install it and the airbag light comes on?
This is a known possibility. The BCM and the airbag system (SDM) communicate for security. If the light appears, it simply means they need to be re-synced. A technician with a proper scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve it.
