scangauge e "2 not rdy"

[Perry]

When I go to scan my vehicle with the ignition on with engine off its says "2 not rdy" on the bottom. what does this mean? When the engine is running it says "? codes" with <veiw frz> under it. Kinda weird doesn't really say much in the manual about it. When i used it in parents car it just said no codes and ready.

I have to say I'm pretty pleased with it besides that. I like how you can change the tire size for much more accurate readings.

To read the codes you have to have the engine running.
