Programmed 2002 Suburban 1500 BCM Body Control Module 15095334

Restore Your GM Truck’s Electrical System with a Reliable BCM

Are you chasing electrical gremlins in your 2002 Suburban 1500? Flickering interior lights, malfunctioning power windows and locks, or a security system that acts up on its own are classic signs of a failing Body Control Module (BCM). As the central command for your vehicle’s body electronics, a faulty BCM can cause a cascade of frustrating, seemingly unrelated problems. In my 20+ years of hands-on diagnostics, I’ve seen how a failing BCM can mimic a dozen other issues, leading to wasted time and money on incorrect repairs. This module is the definitive solution to restore order and reliability to your truck’s essential functions.

This isn’t just a replacement part; it’s a complete, ready-to-install solution. We handle the critical programming for you. Simply provide your vehicle’s VIN during checkout, and our technicians will flash this BCM with the latest GM software specific to your 2002 Suburban 1500. This process ensures seamless integration with your vehicle’s existing systems, eliminating the need for an expensive trip to the dealership for programming. It’s the most direct path to getting your truck back to 100% functionality.

Common Signs of a Failing BCM

• ✔ Intermittent or non-working power windows, door locks, or mirrors.
• ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
• ✔ The security system or alarm randomly activating or preventing the vehicle from starting.
• ✔ A recurring parasitic battery drain that kills your battery overnight.
• ✔ Unresponsive key fob or remote entry functions.
• ✔ Erratic behavior from the radio or climate control system.
• ✔ Diagnostic trouble codes (DTCs) related to communication loss, such as U-series codes, or specific BCM faults.

A Straightforward Guide to Installation

1. ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
2. ✔ Locate the BCM: On most 2002 GM full-size trucks and SUVs like the Suburban, the BCM is located under the driver’s side of the dashboard, near the steering column. You may need to remove a lower dash panel for access.
3. ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket and remove it from the vehicle.
4. ✔ Install the New BCM: Mount your new, pre-programmed BCM into the bracket and securely plug in all the electrical connectors. You should hear a ‘click’ as they lock into place.
5. ✔ Reconnect and Test: Reinstall any trim panels you removed. Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—windows, locks, lights, radio, etc.—to confirm proper operation.
6. ✔ Post-Installation Procedures: In some cases, additional steps may be needed. If your airbag light is on, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. A brake pedal position relearn may also be necessary for certain models.
