Just a heads up for everyone. Tech support emailed me about this issue. I don'the know if they fully understood what I was trying to communicate to them, but they said they would pass it on to the engineers. They asked what would be the point of clearing codes if the MaxiSYS did not retreive any codes from the vehicle? I realize it seems remedial at first, but clearing codes also resets the on board monitors, and clears any codes that the vehicle may have but does not show on the MaxiSYS. Case in point, the Prius I was working on had a fault message, and if my Toyota Techstream wasn't out for repair, would have shown the possible code and/or sub-code causing the message to pop up on the driver information center, and been able to clear code/message. I'm not knocking my tool, I really love my MaxiSYS. I realize that no aftermarket scan tool is perfect. Just saying that it needs a little spit and polish from time to time. It still does more than any of my other scan tools ever dreamed of.
