Tired of Chasing Electrical Gremlins in Your GM Truck?
As a technician with over two decades under the hood, I’ve seen it all. A customer comes in with a 2002 Yukon, and the complaint list is a mile long: the radio presets are gone, the power windows have a mind of their own, the security light is flashing, and the dome light won’t turn off. They’ve replaced the battery and checked the fuses, but the problems persist. The culprit? A failing Body Control Module (BCM). This isn’t just a box of wires; it’s the central command for your vehicle’s comfort and convenience features. When it starts to fail, it can make your reliable truck feel haunted.
This is the definitive solution for your vehicle’s electrical woes. We’re offering a genuine replacement BCM, part number 15081796, that comes fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). This means you can skip the expensive trip to the dealership for programming. We handle the complex part, loading the latest GM software updates onto the module before it even leaves our facility. All you need to do is provide your VIN after purchase, and we’ll ship a BCM that’s ready for installation in your 2002 Yukon BCM or other compatible GM vehicle.
From the Diagnostic Bay
A customer’s 2002 GMC Sierra came in last week with these exact symptoms. The dash lights would flicker intermittently, and the power locks would cycle while driving. He was convinced it was a complex wiring short. After confirming solid power and ground at the BCM connector, we diagnosed a faulty module. Instead of a costly, time-consuming repair at the dealer, we installed one of our pre-programmed units. The physical swap took less than 30 minutes. After performing the simple security and airbag relearn procedures, the truck was back to 100% functionality. The customer was thrilled to have his truck back to normal without the dealership hassle and expense.
Is Your GM Truck or SUV Showing These Symptoms?
A failing BCM can cause a wide range of confusing issues. If you’re experiencing any of the following, this module is likely the fix you need:
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lighting (dome lights, headlights).
- ✔ Security system faults or a vehicle that won’t start due to the anti-theft system.
- ✔ Gauges on the instrument cluster behaving strangely or not working at all.
- ✔ Radio or climate control malfunctions.
- ✔ False warning lights on the dashboard.
A Straightforward Guide to Your BCM Swap
Installing your new 2002 Yukon BCM is a manageable job for a confident DIYer. While the exact location varies slightly by model, the process is generally similar.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on electrical components.
- Locate the BCM: On most full-size trucks and SUVs like the Yukon, Tahoe, and Silverado, the BCM is located under the driver’s side of the dashboard, near the steering column. On vans like the Astro and Safari, it’s often behind the center dash.
- Remove Connectors: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Do not force them.
- Swap the Module: Unbolt or unclip the old BCM and remove it. Install the new, pre-programmed module in its place.
- Reconnect Everything: Plug the electrical connectors firmly into the new BCM and reconnect the negative battery terminal.
- Perform Relearn Procedures: This is a critical step. You will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a capable scan tool to clear the airbag light. Some vehicles may also require a brake pedal position sensor relearn. These ensure all systems communicate correctly with the new BCM.

Frequently Asked Questions
What exactly does a Body Control Module do?
The BCM is a computer that controls many of your vehicle’s non-engine-related functions. This includes power windows, locks, lights, the security system, wipers, and the instrument panel. It’s the brain for your vehicle’s body electronics.
Is this BCM really plug-and-play?
Because we program it to your VIN, it is a direct physical replacement that will allow your vehicle to start and run. However, for full functionality and to clear certain warning lights (like the airbag light), you must perform the post-installation relearn procedures mentioned, which require a suitable diagnostic tool.
What information do you need from me?
After you complete your purchase, we simply need your 17-digit Vehicle Identification Number (VIN). This allows us to program the module with the correct software and settings for your specific vehicle configuration.
What happens if I don’t perform the airbag and brake relearn procedures?
If the ‘Setup SDM Primary Key’ procedure is not done, the airbag warning light will remain on, and the supplemental restraint system may not function correctly. If a brake pedal relearn is required and not performed, you may experience issues with brake light operation or cruise control.
Can I install this myself?
Yes, a person with moderate mechanical skill can physically swap the module. The main challenge is having access to a bi-directional scan tool capable of performing the necessary relearn procedures after installation. Many local independent shops can perform these for you if you don’t have the tool.
