Restore Full Control Over Your GM Truck’s Electronics
If you’re dealing with bizarre electrical problems in your 2003-2006 GMC Yukon XL 2500, a failing Body Control Module (BCM) is the likely culprit. As the central command for your vehicle’s comfort and security features, its failure can cause immense frustration. This OEM-quality replacement BCM, part number 15116066, is offered with our expert cloning service. This means we transfer all the original, vehicle-specific data from your old module to this new one, creating a true plug-and-play solution that bypasses expensive dealership programming and gets you back on the road fast.
Is Your GM Truck or SUV Showing These Symptoms?
A failing BCM can manifest in numerous ways. Over my 20 years in the field, I’ve seen these modules cause some of the most confusing electrical issues. Here are the most common signs that your BCM needs replacement:
- ✔ Intermittent or total loss of power windows, door locks, or interior lighting.
- ✔ HVAC controls not responding or the blower motor working erratically.
- ✔ The security system acting up, leading to a no-start condition or the alarm going off randomly.
- ✔ An illuminated airbag light on the dash, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ A flood of communication (U-codes) or other body-related DTCs stored in the system.
- ✔ Wipers, radio, or other accessories working intermittently or not at all.
A Straightforward Guide to Installation
Our cloning service makes the physical installation incredibly simple. Since all the programming is done beforehand, you won’t need any special scan tools for the core part of the job.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work. This prevents short circuits and helps reset the vehicle’s systems.
- Locate the BCM: On most compatible trucks and SUVs like the Yukon XL 2500, the BCM is located under the driver’s side dashboard, near the steering column. It’s typically held in place by plastic clips or a couple of small bolts.
- Swap the Modules: Carefully disconnect the electrical connectors from the old BCM. The connectors have locking tabs, so be sure to depress them fully before pulling. Remove the old module and install the new, cloned BCM in its place.
- Reconnect and Test: Re-attach the electrical connectors, ensuring they click securely into place. Reconnect the battery terminal. Start the vehicle and test all body functions—windows, locks, lights, HVAC, etc.—to confirm the repair.
Post-Installation Note: In some cases, you may need a professional scan tool for follow-up procedures like the ‘Setup SDM Primary Key in BCM’ if the airbag light remains on, or a ‘Brake Pedal Position Relearn’. Always refer to a service manual for vehicle-specific requirements.

Frequently Asked Questions
What is a BCM cloning service?
Our cloning service is a process where we transfer the complete software and vehicle-specific configuration data from your original, failing BCM directly onto the replacement module. This ensures 100% compatibility with your vehicle’s options and security system, eliminating the need for further programming.
Do I need to send my original BCM to you?
Yes. For the cloning service to work, you must ship your original Body Control Module to us. We will perform the data transfer and ship both your original module and the ready-to-install replacement back to you.
Why is cloning better than just programming a new BCM?
Cloning is a more comprehensive data transfer. It copies not just the VIN, but all the specific settings and software unique to your vehicle’s factory options. This prevents compatibility issues that can sometimes arise with standard VIN programming, providing a more reliable, hassle-free repair.
Is there a core charge for this part?
No. There is no core charge because we always return your original module to you along with the newly programmed replacement. You get to keep your old part.
Will I need a scan tool after installation?
For the basic functions, no. The module is plug-and-play. However, if your vehicle displays an airbag light after installation, a professional scan tool will be required to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the security systems.
