What is an OBD2 Scanner?

An OBD2 scanner is a device used to read and diagnose vehicle fault codes, offering insights into engine light warnings and performance issues. These scanners connect to your car's onboard diagnostic system, accessing the trouble codes that identify specific engine and component issues. Modern OBD2 scanners can read a multitude of codes and provide valuable information to repair technicians and DIY enthusiasts alike.
