2002 Suburban 1500 BCM Body Control Module 15081796 Programmed to VIN

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

Are you chasing down bizarre electrical issues in your 2002 GM truck or SUV? Flickering headlights, a dashboard that seems to have a mind of its own, or power accessories that work one minute and not the next are classic signs of a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can cause a cascade of frustrating and hard-to-diagnose problems. This isn’t just an inconvenience; it can affect safety systems like your brake lights and security features. We offer a reliable, straightforward fix: a replacement BCM, part number 15081796, programmed specifically for your 2002 Suburban 1500 BCM using your vehicle’s VIN.

Is Your GM Truck Showing These Symptoms?

• ✔ Intermittent or non-functional power windows, door locks, or mirrors.
• ✔ Erratic or dead instrument cluster gauges (speedometer, tachometer, fuel gauge).
• ✔ Headlights, taillights, or interior lights flickering or staying on.
• ✔ The security or anti-theft system preventing the vehicle from starting.
• ✔ False warning lights, such as “Service 4WD” or brake system alerts.
• ✔ Communication Diagnostic Trouble Codes (DTCs) like U0140, U0155, or B1001.
• ✔ The radio or climate control system behaving erratically.

The Easiest Way to Replace Your BCM

The biggest hurdle in replacing a BCM has always been the expensive and complicated programming required at a dealership. We eliminate that step entirely. Simply provide us with your vehicle’s VIN during checkout, and our technicians will program the module with the latest GM software updates specific to your truck. It arrives at your door ready for installation, saving you a trip to the dealer and hundreds in programming fees. Plus, there is no core charge, so you can keep your old part.

A Straightforward Guide to Installation

1. ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow the system’s capacitors to discharge.
2. ✔ Locate the BCM: On most compatible models (like the Silverado, Suburban, and Tahoe), 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 panel.
3. ✔ Remove Connectors: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed to be released. 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 BCM in its place.
5. ✔ Reconnect and Test: Plug the electrical connectors firmly into the new module. Reconnect the battery terminal. Turn the key to the ‘On’ position and test all body functions (lights, locks, windows, etc.) to ensure proper operation before starting the engine.

Important Post-Installation Steps

While our programming handles the critical vehicle-specific data, some systems may require a relearn procedure after the new 2002 Suburban 1500 BCM is installed. This is normal and ensures all components communicate correctly.

• Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag module.
• Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct brake light operation and to prevent issues with the traction control system.

Disclaimer: Vehicle systems can vary. We always recommend consulting a factory service manual or a qualified technician if you are unsure about any step of the process.
