Restore Full Control of Your GM Vehicle’s Electronics
Are you battling frustrating electrical gremlins in your 2010 GMC Yukon XL 1500? Flickering lights, unresponsive power windows, or a security system that acts up randomly are classic signs of a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can cause a cascade of confusing and seemingly unrelated problems. After 20 years of diagnosing these exact issues, I can tell you that swapping the BCM isn’t just about replacing a part—it’s about restoring the vehicle’s core functionality and your peace of mind.
This isn’t just a replacement part; it’s a complete, hassle-free solution. We offer a professional Cloning Service for this BCM. Simply send us your original module, and we will transfer all the critical vehicle-specific data—including VIN, mileage, and key information—to this replacement unit. The result? A truly plug-and-play module that requires no expensive trip to the dealership for programming. It arrives at your door ready for installation, loaded with the latest GM software updates for optimal performance.
Case Study: The Haunted Yukon
A customer brought in a 2010 Yukon XL with a laundry list of bizarre symptoms. The radio would turn on and off by itself, the driver’s side power window worked intermittently, and occasionally the truck wouldn’t start, displaying a ‘Service Theft Deterrent System’ message. They had already replaced the battery and checked the alternator. My scan tool pulled a U0140 (Lost Communication With Body Control Module) code. Instead of just throwing parts at it, we pulled the BCM. After years of seeing these, I know that internal circuit board corrosion from moisture intrusion is a common culprit. By providing a cloned 2010 Yukon XL BCM, we had them back on the road in an afternoon, with all electronics working perfectly, saving them hundreds compared to a dealership repair and programming.
Is Your GM Vehicle Showing These Symptoms?
- ✔ Power windows, door locks, or interior lights not working or behaving erratically.
- ✔ The security system or keyless entry fails to operate correctly.
- ✔ Warning lights on the dashboard (like ABS, Airbag, or Traction Control) illuminate for no reason.
- ✔ Communication error codes, such as U0140, U0155, or other ‘U’ codes, are present.
- ✔ The vehicle won’t start, and the theft deterrent light is flashing.
- ✔ Wipers or the horn activate unexpectedly or not at all.
A Straightforward Guide to BCM Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts. Wait at least 10 minutes for all systems to power down.
- ✔ Locate the BCM: On most GMT900 trucks and SUVs like the Yukon, the BCM is located under the driver’s side of the dashboard, near the steering column. You may need to remove a lower dash panel for access.
- ✔ Disconnect and Remove: Carefully unplug the multiple wiring harness connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old BCM from its mounting bracket.
- ✔ Install the New Module: Mount your new, pre-programmed BCM in the same location. Securely reconnect all wiring harnesses, ensuring each connector clicks into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test all body functions: windows, locks, lights, wipers, and radio.
- ✔ Perform Relearns (If Needed): Start the vehicle. If any warning lights appear (like the airbag light), a post-install procedure may be required. See our FAQ and post-install notes for more details.

Frequently Asked Questions
Frequently Asked Questions
How does the Cloning Service work?
After you place your order, we will provide instructions for shipping your original BCM to us. Our technicians will extract the unique data and transfer it to the replacement module. This ensures all your vehicle’s options and security information are retained, making the installation seamless without needing a dealer.
Do I need to provide my VIN?
While the cloning process transfers data directly from your old module, providing your VIN helps us verify the module is correct for your vehicle and ensures we load the latest factory software updates from GM specific to your build.
What happens to my old BCM?
Your original BCM is always returned to you along with the newly programmed replacement unit. We do not keep your original part.
What if my airbag light comes on after installation?
In some cases, the new BCM needs to be synced with the airbag system (SDM). This is a simple ‘Setup SDM Primary Key in BCM’ procedure that can be performed by any shop with a professional-grade diagnostic tool.
Is this a difficult part for a DIYer to replace?
The physical replacement is straightforward for someone with basic mechanical skills. It’s typically located under the dash and held in by a few bolts or clips. Our cloning service eliminates the most difficult part—the computer programming—making it very DIY-friendly.
Disclaimer: Vehicle systems are complex. While our cloning service simplifies installation, some models may require additional relearn procedures (e.g., Brake Pedal Position Sensor). Always consult a factory service manual or a qualified technician if you are unsure.
