  1. I have a 2010 Acura RDX that is displaying “check emission system” will the Innova work for me?
    If I purchase a code reader and turn off the message, will it require repeated turn off or does it remain off?
    Also I have an iphone 6s, is this something I would want to use with the scanner?

    any recommends are appreciated!
