1. Introduction and Overview
The OBDLink SX USB is a professional-grade OBD-II automotive scan tool designed to transform your Windows PC, laptop, or tablet into a powerful diagnostic device. It enables users to read and clear 'Check Engine' lights, retrieve trouble codes, and monitor real-time engine data for most 1996 and newer cars and light trucks sold in the USA (excluding hybrid or electric vehicles).
This device connects to your vehicle's OBD-II port and to your computer via a standard USB-A connection, providing a reliable and fast communication link for vehicle diagnostics.
