Restore Full Electrical Function to Your GM Truck or SUV
Is your 2010 GMC Yukon XL 1500 acting possessed? Flickering lights, malfunctioning power windows, a security system that won’t cooperate, or even a frustrating no-start condition can all point to one culprit: a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, when the BCM goes down, it can create a cascade of confusing and unpredictable problems. I’ve spent years in the shop diagnosing these exact issues, and I understand how disruptive it can be when your vehicle’s basic functions become unreliable.
This isn’t just a replacement part; it’s a complete, hassle-free solution. We provide a professional cloning service that makes this repair as simple as possible. You send us your original BCM, and we perform a precise, 1-to-1 data transfer to this fully tested replacement unit. This means all your vehicle-specific information—including VIN, mileage, and key data—is perfectly mirrored. The result? A module that is truly plug-and-play, eliminating the need for an expensive trip to the dealership for programming. We then ship both your original module and the ready-to-install replacement back to you.
A Technician’s Notebook: The Intermittent Gremlin
A customer brought in a 2010 Tahoe—which uses a nearly identical electrical system to the Yukon XL—with a problem that was driving him crazy. The radio would randomly shut off, the door locks would cycle while driving, and occasionally, it wouldn’t start, with only a click from the starter. He’d already replaced the battery and checked the alternator. After hooking up my scan tool, I noticed several U-codes (U0140, U0155) indicating a loss of communication with the BCM. These intermittent communication drops are a classic sign of internal BCM failure, often from failing solder joints or capacitors. By installing a BCM with cloned data, we had him back on the road the same day with all electrical gremlins gone for good. This is the exact, reliable fix we offer here.
Is Your Vehicle Showing These Symptoms?
- ✔ Intermittent or non-functional power windows, door locks, or interior lights.
- ✔ The security or anti-theft light stays on, preventing the engine from starting.
- ✔ Erratic gauge behavior or warning lights that come on for no reason.
- ✔ Communication error codes (U-codes) stored in other modules, pointing to the BCM.
- ✔ A battery that drains overnight due to the BCM not properly shutting down accessories.
- ✔ Horn, wipers, or other accessories activating on their own.
A Straightforward Guide to BCM Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow all systems to power down completely.
- ✔ 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 a few trim panels 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: Seat the new, cloned BCM into the mounting bracket and plug in all the electrical connectors. Ensure they click securely into place.
- ✔ Post-Installation Checks: Reconnect the battery terminal. Turn the key to the ‘On’ position (without starting) and verify that your power accessories are working correctly. Start the vehicle.
- ✔ Final Relearn Procedures: In some cases, you may need to perform a relearn procedure. If the airbag light is on, a ‘Setup SDM Primary Key’ procedure may be needed with a high-end scan tool. A ‘Brake Pedal Position Relearn’ might also be required for proper brake light and traction control operation. Always refer to a service manual for model-specific steps.

Frequently Asked Questions
What exactly is a ‘Cloning Service’?
Cloning is a process where we transfer the complete software and vehicle-specific data (like VIN, mileage, and key codes) from your original BCM to the replacement unit. This makes the new module a perfect electronic match for your vehicle, so it works immediately upon installation without any additional programming.
Do I need to get this programmed by a dealer after I receive it?
No. Because we clone your original data, this module arrives ready to install. This plug-and-play solution saves you the time, cost, and hassle of a dealership visit for programming.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is not functioning in the vehicle, we can still extract the necessary data directly from the memory chip. Please contact us before ordering if your module is severely damaged by water or fire.
Why do you send my old part back?
We return your original module because it’s your property and for your peace of mind. It confirms that the data was transferred and serves as a backup. We do not require a core deposit or keep your old part.
Will this fix my specific problem?
This BCM will resolve issues directly caused by a faulty module. While the symptoms listed are very common for BCM failure, we always recommend a proper diagnosis by a qualified mechanic to rule out other potential causes like wiring or sensor faults. A faulty 2010 Yukon XL 1500 BCM is a very common failure point for these electrical issues.
