Restore Your Truck’s Electrical System with a Plug-and-Programmed Solution

Are you chasing electrical gremlins in your 2002 GMC Yukon or other GM truck? Flickering lights, power windows with a mind of their own, a security system that won’t let you start the engine, or random warning lights on the dash are classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it goes bad, it can cause a host of frustrating and unpredictable problems. Don’t let a faulty module sideline your reliable truck. This is a direct-fit, professionally programmed replacement that gets you back in control.

We take the biggest headache out of the repair: the programming. Forget about towing your vehicle to a dealership and paying high labor rates for programming. Simply provide us with your vehicle’s VIN during checkout, and our technicians will flash this BCM with the latest, most stable software from General Motors specifically for your truck. This ensures all factory-installed options work correctly right out of the box. This is the smart, efficient fix for any DIY mechanic or professional shop looking to save time and money on a 2002 Yukon BCM replacement.

Is Your GM Truck or SUV Showing These Signs?

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

• ✔ Erratic or non-functional interior/exterior lights
• ✔ Power windows, mirrors, or door locks operating intermittently
• ✔ The security or anti-theft system preventing the engine from starting
• ✔ Horn honking unexpectedly or not working at all
• ✔ Wipers behaving erratically (e.g., won’t turn off)
• ✔ False warnings on the driver information center (DIC)

Your Straightforward BCM Installation Guide

Installing your new 2002 Yukon BCM is a manageable job for a DIYer. While the exact location varies slightly by model (see fitment list), the process is generally the same.

1. Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
2. Locate the BCM: On most trucks and SUVs like the Yukon and Tahoe, it’s located under the driver’s side of the dashboard, near the steering column. On vans like the Astro/Safari, it’s often behind the center dash.
3. Remove Connectors: Carefully unplug the multiple wiring harness connectors from the old BCM. They have locking tabs that need to be depressed. Do not force them.
4. Swap the Module: Unbolt or unclip the old BCM from its mounting bracket and remove it. Install the new, pre-programmed module in its place.
5. Reconnect Everything: Plug all wiring harnesses securely into the new BCM. You should hear a ‘click’ as they lock in. Reconnect the negative battery terminal.
6. Perform Final Procedures: Follow the critical post-installation steps outlined below to ensure full functionality.

Critical Post-Installation Requirements

IMPORTANT: After installing your new BCM, two procedures may be required to restore full vehicle function and safety. Failure to perform these steps can result in warning lights and improper system operation.

• Airbag System Reset: The airbag warning light will likely be on. You must use a capable diagnostic scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This re-establishes communication between the new BCM and the airbag module (SDM).
• Brake Pedal Position Sensor (BPPS) Relearn: Some vehicles require a recalibration of the brake pedal sensor. If your brake lights are not functioning correctly, this procedure will be necessary.

Note: If you are not comfortable performing these procedures, please consult a professional technician.
