Autel MaxiScan MS300 Simple But Effective

I spent a bit of time researching OBD scanners before I bought my Autel MaxiScan. There are many many options available out there in the market - USB connectivity, SD card slots, full displays, detachable cords, and so on. Although the more you spend the more features you get, there are three major features I think an OBD scanner must do: 1) pull generic AND manufacturer codes, 2) delete codes/reset the computer, and 3) check if the computer and the subsystems (02 sensors, ERG system, and so on) are ready to be inspected.

This tiny unit does all three major functions - and that's about it. It will only display the code, not what hit means. But it comes with a book that interprets generic codes, and a CD for manufacturer specific codes. All this information is also readily available online.

If you don't need an OBD scanner with tons of features and just need the core functions, this is a great little unit and has been well worth the small investment. You'll be surprised how many of your friends have lit check engine lights that you can help them with.
