Types of Engine Diagnostics Tools

From simple code readers to advanced scan tools, the market offers a wide array of engine diagnostics tools. Each tool caters to different needs and skill levels. Understanding these differences is crucial for choosing the right tool for your specific requirements.

OBD-II Scanners: The Foundation of Diagnostics

OBD-II, or On-Board Diagnostics, scanners are the most common type of engine diagnostics tools. They connect to your vehicle’s OBD-II port, usually located under the dashboard, and retrieve diagnostic trouble codes (DTCs). These codes provide clues about potential issues within the engine and other vehicle systems. Basic OBD-II scanners simply display the codes, while more advanced models offer additional features like live data streaming, freeze frame data, and emissions testing capabilities.
