Restore Your Yukon’s Brain and End Electrical Chaos
Are you chasing electrical gremlins in your 2010 GMC Yukon? Flickering dashboard lights, power windows with a mind of their own, or a security system that randomly goes off can be incredibly frustrating. In my 20+ years of diagnostics, these phantom issues often point to one culprit: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, managing everything from your interior lights and power locks to the anti-theft system. When it starts to fail, it can make your reliable truck feel unpredictable.
Don’t let a faulty module keep you guessing. This is a direct-fit replacement Body Control Module, part number 25847589, for your GM vehicle. The best part? We take the biggest headache out of the repair. Simply provide us with your vehicle’s VIN (Vehicle Identification Number) after purchase, and our technicians will program the BCM with the latest GM software specifically for your truck. It arrives at your door ready to be installed, saving you a costly trip to the dealership for programming. This is the straightforward, reliable solution to get your truck’s features working correctly again.
A Technician’s Notebook
A customer brought in a 2010 Yukon last month with a classic case of BCM failure. The complaint was intermittent no-start, the radio would stay on after the key was removed, and the power door locks worked only when they wanted to. A scan showed a slew of communication error codes. Instead of spending hours tracing wires for a phantom short, we went straight for the BCM. After installing one of our pre-programmed units, every single issue was resolved on the first try. This part saved the customer hundreds in diagnostic time and dealership programming fees.
Common Signs of a Failing BCM
- ✔️ Erratic or non-functional power windows, door locks, and mirrors.
- ✔️ Dashboard lights flickering, staying on, or not working at all.
- ✔️ The security system engaging randomly or preventing the vehicle from starting.
- ✔️ Horn honking unexpectedly or not working when pressed.
- ✔️ Interior dome lights or exterior lights behaving unpredictably.
- ✔️ Communication errors with other modules stored in the vehicle’s computer.
A Straightforward Guide to Your BCM Swap
Replacing the 2010 Yukon Body Control Module is a manageable job for a confident DIYer. The BCM is typically located under the driver’s side of the dashboard, near the steering column.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electrical components.
- Locate the BCM: On the 2010 Yukon, you’ll find it under the 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. They have locking tabs that need to be depressed. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed BCM into place. Reconnect all the electrical connectors firmly, ensuring they click into place.
- Reconnect Battery: Reattach the negative battery terminal.
IMPORTANT: Post-Installation Procedures
After installing your new 2010 Yukon Body Control Module, a few final steps are required to ensure all systems function correctly and safely. These procedures typically require a professional-grade scan tool.
- Airbag System Reset: To clear the airbag warning light, you must perform the ‘Setup SDM Primary Key in BCM’ procedure. This re-establishes communication between the BCM and the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Sensor Relearn: Some vehicles require the Brake Pedal Position (BPP) sensor to be recalibrated. This ensures the brake lights and stability control system receive accurate input.
Note: If you are not equipped or comfortable performing these relearn procedures, we strongly recommend seeking assistance from a qualified professional mechanic.

Frequently Asked Questions
Do I need to send my old BCM back to you?
No, there is no core charge or need to return your old part. This is a direct purchase.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship the module until we have this information.
Is this part difficult to install myself?
The physical installation is straightforward for someone with basic mechanical skills. However, please review the ‘Post-Installation Procedures’ section, as some final steps require a professional scan tool.
What happens if I install it without doing the relearn procedures?
You will likely have persistent warning lights on your dash, such as the airbag light, and certain systems like traction control may not function correctly. These steps are crucial for safety and full functionality.
Will this BCM fix my key fobs not working?
A failing BCM is a very common cause for key fob and remote start issues. While not a guarantee for every situation, replacing a faulty BCM often restores this functionality. A key fob relearn procedure may be required after installation.
