Restore Full Functionality to Your GM Vehicle
Are you dealing with a cascade of bizarre electrical issues in your 2010 GMC Yukon XL 1500? Flickering lights, power windows with a mind of their own, a security system that won’t cooperate, or even a vehicle that refuses to start can all point to one culprit: a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can create frustrating and unpredictable problems. This replacement Body Control Module, part number 25826125, is the reliable, straightforward solution you’ve been looking for.
We take the guesswork and expense out of the repair. Simply provide your vehicle’s VIN during checkout, and our technicians will program the module with the latest GM software specific to your Yukon XL. This means it arrives at your door ready for installation, saving you a costly trip to the dealership for programming services. It’s the most efficient way to get your truck back to 100%.
A Technician’s Notebook
I remember a 2010 Yukon XL 1500 that came into my bay with a classic case of BCM failure. The customer reported the radio would turn on and off, the dome lights wouldn’t work, and the final straw was an intermittent no-start condition. A scan tool showed a laundry list of U-codes (communication errors), pointing to a network breakdown. After verifying power and ground at the BCM connector, we confirmed the module itself was the issue. Swapping in a pre-programmed unit like this one had the truck running perfectly in under an hour, resolving all the ghost-like electrical problems at once.
Is Your Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ The security system or keyless entry malfunctioning.
- ✔ The instrument cluster displaying incorrect information or warning lights (like the airbag light).
- ✔ Communication error codes, such as U0140, U0155, or other U-series DTCs.
- ✔ A parasitic battery drain that leaves you with a dead battery overnight.
- ✔ Intermittent no-start or no-crank conditions.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- ✔ Locate the BCM: On the 2010 Yukon XL 1500, the BCM is typically located under the steering column, behind the driver’s side lower dash panel. You may need to remove this 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, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Mount your new, pre-programmed BCM in the same location. Securely reconnect all electrical connectors, ensuring they click into place.
- ✔ Reconnect Power: Reattach the negative battery terminal.
- ✔ Perform Final Checks: Start the vehicle and test all body functions—windows, locks, lights, radio, etc. Note that some models may require the additional procedures listed below.
Important Post-Installation Notes
While our VIN programming handles the critical setup, some GM vehicles require a final handshake between modules after installation. Be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor relearn may be required on certain models.

Frequently Asked Questions
Does this BCM really come programmed?
Yes. We use the VIN you provide at checkout to flash the module with the latest GM-approved software for your specific vehicle configuration. This makes the installation process much simpler than buying a blank module.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
Is this a difficult part to install myself?
For someone with basic mechanical skills and tools, this is a very manageable job. The primary challenge is accessing the module’s location under the dash. Since the programming is done for you, the electrical part is just plug-and-play.
What tools are required for the post-installation procedures?
The Airbag System Sync and Brake Pedal Position Relearn procedures require a professional-grade bidirectional scan tool (like a GM Tech 2, MDI, or equivalent high-end scanner). Many local repair shops can perform these services if needed.
Will this fix a parasitic battery drain?
A failing BCM is a very common cause of parasitic battery drain because it may not be properly shutting down or going into ‘sleep’ mode. While not a guarantee for every situation, replacing a faulty BCM often resolves this issue.
What if my original part number is not 25826125?
This module replaces a long list of interchangeable GM part numbers. Please review the detailed part number list on this page. As long as your original number is on our list, this module will function correctly in your vehicle.
