Thread: OBD eleven Pro from AutoInstruct

  1. Default

    So these cheaper ODB2 tools, can they diagnose why an engine light would be on? As I understand it (admittedly from the limited reading I've done) is that the ODB2 tools diagnose emissions issues only whereas your more expensive units (Ross Tech) do the lot.

    Is that correct?

    Broadly speaking you are not correct.
    It depends on your approach to diagnosis but the OBD Eleven can provide access and diagnosis to most common systems and issues.
    The challenge with he Ross-Tech, which remains the ultimate tool for diagnosis, is understanding the data and how to use the Ross Tech facility - it is not your average weekend warrior level of diagnosis and modification tool and in the hands of the uninformed makes you capable of introducing more features than you remove.
