Tired of Electrical Gremlins in Your GM Vehicle?
As a technician with over two decades of experience, I’ve seen firsthand how a failing Body Control Module (BCM) can turn a reliable vehicle into a source of constant frustration. If your 2010 GMC Yukon, or another compatible GM model, is experiencing bizarre electrical issues—from flickering dashboard lights and erratic power windows to security system warnings or even a no-start condition—the BCM is often the culprit. This module is the central command center for your vehicle’s body electronics, and when it fails, chaos ensues.
This isn’t just a replacement part; it’s a complete, hassle-free solution. We offer a professional Cloning Service for this BCM. This means you send us your original module, and we expertly transfer its unique programming and security data to this fully tested replacement unit. The result? A true plug-and-play module that is ready for installation right out of the box, saving you from a costly and time-consuming trip to the dealership for programming.
A Technician’s Notebook: The Case of the Haunted SUV
I remember a 2010 Yukon that came into my shop with a list of symptoms that sounded like something out of a ghost story. The radio would change stations on its own, the interior lights would pulse dimly at night, and the driver’s power window only worked when it wanted to. The owner had already replaced the battery and checked all the fuses. After connecting my scan tool, I found a series of U-codes (Communication Errors) pointing to the BCM. Instead of just selling him a blank module and sending him to the dealer, we performed a cloning service. By transferring the original data, we preserved all the vehicle’s specific settings. He installed the new module in his driveway in under an hour, and just like that, the haunting was over. This is the power of a properly prepared module.
Is Your Vehicle Showing These Symptoms?
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Dashboard warning lights (like ‘Service StabiliTrak’ or security indicators) that come and go.
- ✔ Interior or exterior lights behaving erratically (staying on, not turning on, or flickering).
- ✔ The horn sounding randomly or not working at all.
- ✔ Communication error codes (U-codes) stored in the system, such as U0140.
- ✔ Remote keyless entry failing to work consistently.
- ✔ A no-start condition due to the vehicle’s anti-theft system not recognizing the key.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On most compatible trucks and SUVs like the 2010 Yukon, the BCM is located under the driver’s side of the dashboard, near the steering column. For vans and cars, it may be in the center dash area.
- ✔ Remove Connectors: Carefully unplug all the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Do not force them.
- ✔ Swap the Module: Unbolt or unclip the old BCM from its mounting bracket and install the new, programmed module in its place.
- ✔ Reconnect Everything: Plug all the electrical connectors firmly into the new BCM. Reconnect the negative battery terminal.
- ✔ Perform Final Checks: Start the vehicle and test all body functions—lights, locks, windows, radio, etc. Note the post-installation procedures below, as some may be required.
Important Post-Installation Information
While our cloning service makes this a plug-and-play repair, some GM vehicles require a relearn procedure to ensure all systems communicate correctly. These do not always need to be performed but are important to be aware of:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be done with a professional scan tool to sync the modules.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary for correct brake light and traction control operation.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any step.

Frequently Asked Questions
What exactly is a ‘Cloning Service’?
Our cloning service involves transferring the essential software, VIN, mileage, and key data from your original BCM to the replacement unit. This makes the new module a perfect electronic match for your vehicle, eliminating the need for dealership programming. Your original module is always returned to you.
Will I need to take my car to the dealer after installation?
No! The primary benefit of our service is that the module arrives pre-programmed for your specific vehicle. This allows you to avoid the hassle and expense of a dealership visit for programming.
What if my airbag light comes on after I install it?
In some cases, the new BCM needs to be electronically ‘introduced’ to the airbag system (SDM). This is a simple procedure called ‘Setup SDM Primary Key in BCM’ that can be performed by any competent repair shop with a professional-grade diagnostic tool.
Is this a difficult part to replace for a DIYer?
For someone with basic mechanical skills, replacing the BCM is very manageable. It typically involves removing a few dash panels for access and unplugging connectors. No specialized tools are usually required for the removal and replacement itself.
How do I send my original BCM to you?
After you complete your purchase, we will provide you with detailed instructions and a shipping address. You simply package your original module securely and send it to us. We’ll handle the rest and ship both the newly programmed unit and your original back to you.
