Restore Full Functionality to Your GMC Yukon XL
Are you battling strange electrical problems in your SUV? Intermittent wipers, a dead climate control panel, or power windows with a mind of their own are classic signs of a failing Body Control Module (BCM). As the central command for your vehicle’s comfort and security features, a faulty BCM can make driving a frustrating experience. This replacement module, part number 15194170, is the definitive solution for your 2003-2006 Yukon XL BCM issues, restoring your vehicle’s electronics to perfect working order.
Case Study: A Tricky Diagnosis
I recently had a 2005 Yukon XL 1500 in my bay that was driving the owner crazy. The radio would turn off randomly, the driver’s side power window wouldn’t work, and the security light was always on, causing an intermittent no-start condition. The owner had already replaced the battery and checked all the fuses. After connecting my scanner, I saw a handful of communication codes (U-codes) and a specific BCM internal fault, B1001. This pointed directly to a BCM failure. Instead of a costly trip to the dealer, we used our cloning service. We transferred the data from his original module to this replacement unit. The result? A 10-minute install, all electrical gremlins gone, and a very happy customer who saved hundreds on dealership fees.
Is Your Yukon Showing These Electrical Issues?
- ✔ Non-responsive or erratic HVAC and climate controls.
- ✔ Power windows, door locks, or interior lights not working correctly.
- ✔ The security system light is on, or the vehicle won’t start.
- ✔ An active airbag warning light on the dash, often with DTC B1001 (Option Configuration Error).
- ✔ Unpredictable behavior from electronic accessories like the radio or wipers.
- ✔ A cluster of seemingly unrelated diagnostic trouble codes (DTCs).
The Power of Our Cloning Service
Forget about expensive dealership programming. Our unique cloning service makes this a true plug-and-play repair. We transfer the critical VIN-specific data, key information, and software from your original module directly onto this replacement unit. This ensures seamless integration with your vehicle’s other systems, like the Powertrain Control Module (PCM) and Sensing and Diagnostic Module (SDM), without any additional setup. You get a module that is 100% matched to your vehicle’s factory options.
A Straightforward Guide to Installation
- ✔ Safety First: Before you begin, always disconnect the negative terminal from your vehicle’s battery to prevent electrical shorts.
- ✔ Locate the BCM: On most 2003-2006 Yukon XL models, the BCM is located under the driver’s side of the dashboard, near the steering column.
- ✔ Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once unplugged, the module can be unclipped or unbolted from its bracket.
- ✔ Install the New Module: Connect the electrical harnesses to your pre-programmed replacement BCM. Ensure they click securely into place. Mount the new module back into the bracket.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all functions: lights, locks, windows, HVAC, and wipers to confirm the repair is complete.
Post-Installation Notes
In some cases, additional steps may be needed:
- Airbag System Sync: If the airbag light remains on after installation, a professional scan tool is required to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper brake light and traction control operation.

Frequently Asked Questions
What is a BCM cloning service?
It’s a process where we transfer the exact vehicle-specific data—including VIN, mileage, and security information—from your original BCM to the replacement unit. This makes the new module plug-and-play, avoiding the need for expensive dealership programming.
Do I need to send my original BCM to you?
Yes, for our cloning service to work, you will need to send us your original module after placing your order. We will perform the service and ship both your original and the newly programmed replacement back to you. We do not keep your old part.
Will this fix my airbag light with code B1001?
A faulty BCM is a very common cause of the B1001 code. Replacing it with our cloned module should resolve the root cause. However, if the light stays on after install, the simple “Setup SDM Primary Key” procedure mentioned above will be needed to clear it.
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 for cloning. If you suspect your module is completely fried (e.g., water damage, burn marks), please contact our expert support team before ordering to discuss options.
Is this part difficult for a DIYer to install?
Not at all. The installation is very straightforward and typically takes less than 15 minutes with basic hand tools. The main challenge is accessing the module under the dash, but no complex procedures are involved in the physical swap.
