Restore Your GM Truck’s Electrical System
Are you battling frustrating electrical issues in your 2002 GM truck or SUV? Intermittent power windows, flickering lights, a malfunctioning security system, or strange behavior from your gauges are common signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and disruptive problems. This replacement Body Control Module is the definitive solution to restore your vehicle’s proper function and reliability.
This unit comes pre-programmed to your vehicle’s specific Vehicle Identification Number (VIN). This means you can skip the expensive trip to the dealership for programming. Simply provide us with your VIN during checkout, and we’ll flash the module with the latest GM software updates, ensuring it’s ready for installation right out of the box. It’s a direct-fit replacement for part number 15063577 and other service numbers listed below.

What to Expect After Installation
While our VIN programming handles the majority of the setup, some vehicles may require minor post-installation procedures to sync with other onboard systems. These are typically simple and can often be done with a capable diagnostic tool.
- Airbag System Sync: If your airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ will be necessary to sync the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure the brake lights and traction control system function correctly.
Please note: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.
