2010 Yukon Body Control Module 15872421 | Programmed to Your VIN

Restore Full Functionality to Your GM Vehicle

Are you dealing with baffling electrical issues in your 2010 GMC Yukon or another GM vehicle? Flickering dash lights, power windows with a mind of their own, or a security system that prevents your truck from starting can be incredibly frustrating. As a technician with over 20 years of experience, I’ve seen these exact problems hundreds of times. The culprit is almost always a failing Body Control Module (BCM), the central computer for your vehicle’s comfort and convenience features.

Don’t let a faulty BCM sideline your vehicle. This is a direct-fit replacement, but with one crucial advantage: we program it to your vehicle’s specific VIN before it ships. This means you can skip the expensive trip to the dealership for programming. We load the latest, most stable software from GM, ensuring your vehicle operates exactly as it should. This isn’t just a part; it’s a complete, hassle-free solution designed to get you back on the road with confidence.

Is Your GM Vehicle Showing These Symptoms?

A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is the likely solution:

• ✔ Erratic or non-functional power windows, door locks, or mirrors.
• ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
• ✔ The security or anti-theft system activating incorrectly, causing a no-start condition.
• ✔ Dashboard warning lights (like the airbag light) appearing for no reason.
• ✔ Issues with the radio, climate control, or other interior accessories.
• ✔ Inconsistent or failed communication with diagnostic scan tools.

A Straightforward Guide to Installation

Installing your new 2010 Yukon Body Control Module is a manageable job for a confident DIYer. While the exact location varies by model (see fitment list), the process is generally similar.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes before beginning.
2. Locate the BCM: On many GM trucks and SUVs like the Yukon, the BCM is located under the driver’s side of the dashboard, near the steering column. On vans and some cars, it may be in the center dash area.
3. Remove Trim Panels: Carefully remove any plastic trim or panels necessary to access the module.
4. Disconnect and Remove: Unplug the electrical connectors. They have locking tabs, so be gentle. Then, unbolt or unclip the old BCM from its mounting bracket.
5. Install the New BCM: Mount the new, pre-programmed module in place and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock.
6. Reconnect Battery: Re-attach the negative battery terminal.

Important Post-Installation Steps

Because this module is central to your vehicle’s safety systems, a couple of final procedures are required to ensure everything works correctly. This is standard for any BCM replacement.

• Airbag System Reset: To clear the airbag warning light, a professional scan tool must be used to perform the ‘Setup SDM Primary Key in BCM’ procedure. This re-establishes communication between the airbag system and the new BCM.
• Brake Pedal Position Sensor Relearn: Some vehicles may require the Brake Pedal Position (BPP) sensor to be recalibrated. This ensures the brake lights and stability control system function correctly.
