The ANCEL AD310 is one of the best-selling OBD II scanners on the market and is recommended by Scotty Kilmer, a YouTuber and auto mechanic. It can easily determine the cause of the check engine light coming on, quickly read and clear diagnostic trouble codes, read live data & hard memory data, view freeze frame, I/M monitor readiness and collect vehicle information. Instead of taking car to mechanic shop, you can use it to check the trouble code and show code definition by yourself.
