Review on C301 OBD2 Scanner Automotive EOBD OBDII Code Reader with Battery Test Car Diagnostic Tool for Check Engine Light [2022 Updated Version] by Ronald Dimatulac

I'm not very mechanically savvy and know enough about auto mechanics to know when to call a professional. This OBD2 scanner is a mix of analog and digital device. I expected more from a digital device that displays a graphical user interface and not just numerical data results. In any case, the results are good and understandable for me. I have a 2008 Toyota Prius that sometimes shows the check engine light for reasons unknown to me. I took it to the dealer for regular service and they just cleared the fault code and said everything was fine. Just recently my check engine light came on again so I hooked up the OBD2 and ran a test. I got code P0016 which says it could be a problem with the Engine Control Module (ECM). I have to play with it a bit more to really feel it.
