Connecting your OBD (On-Board Diagnostics) tool to a computer offers significant advantages for vehicle diagnostics and maintenance. The OBD system is a standardized system used in modern vehicles to monitor and control various engine and vehicle parameters.

1.1. What is OBD?

OBD, or On-Board Diagnostics, is an electronic system that monitors the performance of a vehicle’s engine, emissions control system, and other components. It was standardized in the United States in the 1990s to ensure vehicles meet emissions regulations. Modern OBD systems, known as OBD-II, provide real-time data and diagnostic trouble codes (DTCs) to help technicians identify and resolve issues.

According to the EPA (United States Environmental Protection Agency), OBD-II systems are designed to monitor nearly all components that can affect emissions, ensuring vehicles comply with environmental standards.

1.2. Why Connect Your OBD Tool to a Computer?

Connecting an OBD tool to a computer enhances diagnostic capabilities by:

• Larger Display and Easier Navigation: Computers offer larger screens and user-friendly interfaces compared to handheld OBD scanners.
