Frequently Asked Questions

What is the difference between a basic and an advanced OBD2 scanner?

A basic OBD2 scanner reads and clears generic engine fault codes (DTCs) and checks emissions status. An advanced scanner can access more complex systems like ABS (Anti-lock Braking System), SRS (Airbag System), Transmission, and often includes service functions like oil light resets or battery health analysis.

Are at-home diagnostic health tests as accurate as lab tests?

While convenient, at-home rapid tests (like those for Flu/COVID) are generally highly reliable for detecting the presence of a virus, especially when symptoms are present. However, they may not be as sensitive as PCR lab tests. Always follow up with a healthcare provider if you have concerns or persistent symptoms.

Do I need to update my OBD2 scanner?

Yes, many modern OBD2 scanners require updates to maintain compatibility with newer vehicle models and to fix software bugs. Look for scanners that offer lifetime free updates (like the TOPDON AD500) to ensure long-term usability.
