Additionally, consider the type of diagnostics you need to perform. If you only need to read and clear trouble codes, a basic OBD2 scanner may suffice. However, if you need to perform more advanced diagnostics, such as bi-directional testing or system-specific scans, you'll want to look for a more advanced scanner.
