Restore Your Truck’s Electrical System with a Reliable, Pre-Programmed BCM
Are you chasing down frustrating electrical gremlins in your 2002 GM truck or SUV? Flickering lights, power windows with a mind of their own, a security light that won’t turn off, or random warning messages can all point to one culprit: a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can make your reliable truck feel unpredictable. This isn’t just an annoyance; it’s a matter of function and safety. Stop swapping relays and checking fuses endlessly. We offer a direct-fit, dependable solution with this 2002 Yukon Body Control Module, pre-programmed to your vehicle’s specific VIN.
From the Diagnostic Bay: The Case of the Haunted Tahoe
I once had a 2002 Tahoe in my bay that had its owner completely stumped. The radio would turn on by itself, the door locks would cycle while driving, and the security light was always on, sometimes preventing it from starting. The owner had replaced the battery and alternator, but the problems persisted. After connecting my scan tool, I saw multiple communication error codes (U-codes) pointing to the BCM. These modules, especially on the GMT800 platform, are known for internal solder joint failures over time, causing these exact chaotic symptoms. Installing a VIN-programmed BCM like this one resolved every single issue in under an hour. It’s a common failure I’ve seen dozens of times, and a fresh, correctly programmed module is the definitive fix.
Is Your Truck Showing These Signs of BCM Failure?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is likely the solution you need:
- ✔ Erratic or non-functional power windows, door locks, or mirrors
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all
- ✔ The security or anti-theft light is illuminated, possibly causing a no-start condition
- ✔ Inaccurate or dead gauges on the instrument cluster
- ✔ False warnings on the driver information center (DIC)
- ✔ Diagnostic Trouble Codes (DTCs) such as U0140, B1001, or other B-series and U-series codes
- ✔ Wipers or radio operating intermittently or on their own
Plug-and-Play Simplicity: The VIN Programming Advantage
The biggest hurdle in replacing a BCM is the need for expensive, dealer-level programming. We eliminate that step completely. Simply provide us with your vehicle’s 17-digit VIN during checkout, and our technicians will flash this module with the latest GM software updates specific to your truck. This ensures all factory-installed options work correctly right out of the box, saving you hundreds in dealership programming fees and diagnostic time. Plus, with our no core charge policy, you don’t have to worry about the cost or hassle of sending your old part back.
A Straightforward Guide to BCM Installation
Located under the driver’s side of the dashboard, replacing the BCM is a manageable job for a DIYer with basic tools. Follow these steps for a smooth installation:
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Access the Module: Remove the lower dash panel (knee bolster) below the steering column to gain access to the BCM. It’s typically held in by a few screws or clips.
- Locate the BCM: The BCM is a plastic box with several large multi-pin electrical connectors. It’s often mounted to a bracket near the steering column.
- Disconnect and Remove: Carefully unplug all electrical connectors from the old BCM. Note their orientation. Then, unbolt or unclip the module from its mounting bracket and remove it.
- Install the New BCM: Mount your new, pre-programmed BCM onto the bracket and securely plug in all the electrical connectors. Ensure they click into place.
- Reassemble and Reconnect: Reinstall the lower dash panel and reconnect the negative battery terminal.
- Final Checks: Start the vehicle and test all body functions—windows, locks, lights, wipers, etc.—to confirm proper operation.
Important Post-Installation Information
While our VIN programming handles the majority of the setup, some vehicles may require additional steps with a professional-grade scan tool:
- Airbag System Sync: If the airbag warning light is on after installation, a procedure called “Setup SDM Primary Key in BCM” is needed to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light and traction control operation.
Disclaimer: Always consult a factory service manual or a qualified technician if you are unsure about any part of the installation or post-install procedures.

Frequently Asked Questions About This 2002 Yukon Body Control Module
Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you will receive an email with instructions, or you can simply add your 17-digit VIN to the notes section during checkout. We cannot ship the module until we have your VIN.
Is this part really plug-and-play?
Yes, for over 95% of vehicles. Because we program it to your VIN, it will function immediately upon installation. In rare cases, as noted above, an airbag sync or brake sensor relearn may be required using a scan tool.
Do I need to return my old BCM?
No. This product comes with no core charge, so you can keep your original module without any extra fees or hassle.
What if my part number is slightly different?
This module is a direct replacement for several service numbers, including 15081857, 19208544, and 15095335. As long as your vehicle is on the compatibility list, this part will work.
Will this fix my “Service 4WD” message?
While a BCM can cause a variety of issues, the “Service 4WD” message is more commonly related to the Transfer Case Control Module (TCCM) or the encoder motor. It’s best to have the vehicle scanned for specific codes before ordering.
