OBD-II scanners are the most basic type, designed to read and clear diagnostic trouble codes (DTCs) related to the engine and emissions systems. They are widely available, affordable, and suitable for DIY users who want to perform basic diagnostics.
2. Advanced OBD-II Scanners
These scanners offer additional features beyond basic code reading and clearing. They can provide live data streams, graph sensor readings, and offer some bi-directional control capabilities. Advanced OBD-II scanners are suitable for both DIY enthusiasts and professional mechanics who need more in-depth information.
3. Professional-Grade Scanners
Professional-grade scanners are the most sophisticated and expensive option, offering comprehensive diagnostic capabilities. They can access all vehicle systems, perform advanced programming functions, and provide detailed technical information. These scanners are indispensable for professional mechanics and automotive workshops.
