Restore Full Functionality to Your GM Vehicle
Are you dealing with bizarre electrical problems in your 2010 GMC Yukon? Flickering lights, malfunctioning power windows, a security system that acts up, or a dashboard that seems to have a mind of its own? These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). As the central nervous system for your vehicle’s body electronics, a faulty BCM can cause a cascade of frustrating and unpredictable issues. In my 20+ years of hands-on diagnostics, I’ve seen how a bad BCM can make a perfectly good truck feel unreliable. This isn’t a part you can ignore.
We offer a direct, reliable solution. This is a replacement Body Control Module, part number 25826125, that arrives at your door pre-programmed to your vehicle’s specific VIN. Forget about costly dealership visits for programming and software updates. We handle it all before we ship. By providing us with your VIN during checkout, you receive a module that is truly plug-and-play, loaded with the latest GM software to ensure seamless integration and performance. This is the most efficient way to solve those electrical gremlins and get your truck, van, or SUV operating as it should.
Case Study: A Tricky Diagnosis
A customer brought in their 2010 Tahoe last month with a complaint that was driving them crazy: the interior lights would pulse randomly, the radio would shut off, and the door locks would cycle while driving. They had already replaced the battery and checked the alternator. No warning lights were on, but a scan with a professional tool revealed a handful of U-codes, specifically U0140 (Lost Communication With Body Control Module). This pointed directly to an internal BCM failure. Instead of a multi-day wait and a hefty bill from the dealer, we ordered a VIN-programmed unit like this one. The swap took less than an hour, and after performing the necessary key relearn and SDM setup, the vehicle was completely fixed. This 2010 Yukon Body Control Module is the same solution that saved my customer hundreds in diagnostics and programming fees.
Common Signs of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights).
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Vehicle’s security system engaging randomly, preventing the engine from starting.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Dashboard warning lights appearing and disappearing without reason.
- ✔ Communication-related Diagnostic Trouble Codes (DTCs) such as U0140, U0155, or B1001.
- ✔ Wipers activating on their own or not turning off.
A Straightforward Guide to Installation
For the confident DIYer or professional technician, installing your new 2010 Yukon Body Control Module is a manageable job. The BCM on this platform is typically located under the steering column on the driver’s side.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to allow all systems to discharge.
- Locate the BCM: On the 2010 Yukon and similar platforms (Tahoe, Suburban, Escalade), the BCM is mounted to a bracket under the driver’s side of the dashboard, often near 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 must be depressed. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- Reconnect Battery: Reattach the negative battery terminal.
- Perform Final Procedures: This is a critical step. You will need to perform a Passlock/Security relearn procedure to sync the new BCM with your vehicle’s keys. This can often be done without special tools (consult your vehicle’s service information).
Important Post-Installation Calibrations
After installing your new BCM, two critical procedures may be required to ensure full system functionality and safety. These tasks typically require a professional-grade bidirectional scan tool.
- Airbag System Reset: If the airbag warning light is illuminated, you must perform the ‘Setup SDM Primary Key in BCM’ procedure. This re-establishes communication between the new BCM and the Sensing and Diagnostic Module (SDM), clearing the light and ensuring the airbag system is operational.
- Brake Pedal Position Sensor (BPP) Relearn: Some vehicles require the brake pedal position sensor to be recalibrated after a BCM replacement. This ensures the brake lights, cruise control, and stability control systems receive accurate data from the brake pedal.
Note: If you are not comfortable performing these procedures, we strongly recommend seeking assistance from a qualified mechanic.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that controls many of your vehicle’s non-engine related functions, such as power windows, locks, lights, wipers, security system, and interior accessories. It’s the command center for passenger comfort and convenience features.
Why is providing my VIN so important?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and settings for your vehicle’s specific options and configuration. This ensures a true plug-and-play installation without needing a trip to the dealership for expensive programming.
Can I install this myself?
A knowledgeable DIYer can physically swap the module. However, post-installation procedures like the security relearn, airbag system reset, and brake pedal calibration are critical and may require a bidirectional scan tool. We recommend professional installation if you lack these tools or experience.
Will this fix my ‘Service StabiliTrak’ message?
While a failing BCM can sometimes contribute to stability control warnings due to lost communication or bad sensor data (like from the brake pedal sensor), this message can have many causes. A proper diagnosis is key, but if your BCM is confirmed to be the fault, this part is the correct fix.
Is any other programming required after installation?
The main programming is done by us using your VIN. However, you will need to perform a security relearn procedure to sync your keys to the new BCM. This procedure varies by model but is often detailed in online forums or service manuals and usually doesn’t require a scan tool.
