Restore Order to Your Vehicle’s Electronics
Is your 2010 GMC Yukon or other compatible GM vehicle acting possessed? Flickering lights, malfunctioning power windows or door locks, a security system that won’t cooperate, or strange warnings on the dash are all classic signs of a failing Body Control Module (BCM). As the central command center for your vehicle’s comfort and convenience features, a faulty BCM can turn your daily drive into a frustrating ordeal. I’ve seen it countless times in the shop: a vehicle comes in with a list of bizarre, unrelated electrical gremlins that all point back to this single component.
This isn’t just an inconvenience; it can be a real headache. A failing BCM can even lead to a no-start condition, leaving you stranded. Forget the dealership’s high prices and the hassle of scheduling programming appointments. We offer a simple, reliable solution: a replacement BCM with our expert cloning service. We transfer the exact data from your original module to this replacement unit, ensuring it’s a true plug-and-play fix. This process preserves your vehicle’s specific settings, including key fob programming and factory options, which saves you from expensive and time-consuming post-installation procedures.
A Technician’s Notebook: The Intermittent Gremlin
I remember a 2010 Yukon that came into my bay with the most frustrating symptoms. The owner said the radio would randomly shut off, the driver’s side window would sometimes refuse to go down, and the anti-theft light would flash occasionally. Of course, when I had it, everything worked perfectly. These intermittent issues are the hardest to diagnose. After checking grounds and wiring, I focused on the BCM. By monitoring data streams, I saw erratic voltage outputs from the module that corresponded with the owner’s complaints. We swapped in a BCM with our cloning service, and the problems vanished instantly. The customer was thrilled to have his truck back to normal without a massive bill from the dealer.
Common Signs of a Failing BCM
If your vehicle is exhibiting any of these symptoms, a failing BCM is the likely culprit. A professional scan tool may also show communication-related Diagnostic Trouble Codes (DTCs), such as U0140, U0155, or B1325.
- ✔ Power windows, locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system acting up, preventing the vehicle from starting.
- ✔ The horn sounding unexpectedly or not working.
- ✔ Warning lights (like the airbag or ABS light) illuminating on the dashboard.
- ✔ Wipers behaving unpredictably (e.g., won’t turn off).
- ✔ Key fobs no longer working to lock or unlock doors.
Your Straightforward BCM Installation Guide
Our cloning service makes this a job most DIYers can handle. By transferring your original data, we eliminate the need for dealer-level programming tools.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: In most 2010 Yukon models, the BCM is located under the steering column, on the driver’s side of the dash. Consult a service manual for your specific vehicle’s location if you are unsure.
- Remove the Old Module: Carefully disconnect all electrical connectors from the 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. Reconnect all electrical connectors, ensuring they click securely into place.
- Reconnect Power: Reattach the negative battery terminal.
- Perform Relearns (If Needed): Start the vehicle. In some cases, you may need to perform the post-installation procedures noted below, such as an airbag system sync if the light is on. Test all body functions (lights, locks, windows) to confirm the repair.
Important Post-Installation Information
While our cloning service makes this a plug-and-play process, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the modules and clear the light.
- Brake Pedal Position Relearn: For some models, a brake pedal position sensor relearn might be required to ensure correct brake light operation and to satisfy the traction control system.
Disclaimer: Vehicle systems vary. Always have a factory service manual available for your specific model or consult with a qualified automotive technician.

How does the cloning service work?
After your purchase, you’ll ship your original BCM to us. We use specialized equipment to extract the vehicle-specific data and flash it onto the replacement module. We then ship both the newly programmed unit and your original module back to you.
Do I need to program this BCM after I receive it?
No. Our cloning service makes this a true plug-and-play part. All the necessary software and key information from your old module is transferred, so you can avoid a trip to the dealership for programming.
What do I do if my airbag light comes on after installation?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). This procedure, called ‘Setup SDM Primary Key in BCM’, must be done with a professional-grade scan tool.
What part numbers does this module replace?
This module is a direct replacement for over 30 different GM part numbers, including 15948439, 25892622, and 20815898. Please see the full list in the compatibility section above to confirm your part is included.
Why is cloning a better solution than buying a new BCM?
Cloning is superior because it preserves all your vehicle’s original settings. A new, blank BCM from a dealer requires extensive programming to learn your vehicle’s VIN, key information, and specific options. Our service bypasses that entire process, saving you time and money.
