Understanding OBD II Scan Tools

OBD II scan tools are electronic devices that connect to your car’s OBD II port, typically located under the dashboard on the driver’s side. These tools retrieve diagnostic trouble codes (DTCs), which are codes that indicate specific issues within the vehicle’s systems.

What information can an OBD II scan tool provide? It can reveal everything from minor issues like a loose gas cap to more serious problems like engine misfires or transmission faults. Some advanced scanners can even perform special functions like resetting oil life monitors, activating ABS systems, and coding new keys.
