I found an icon written on elm327 TEST from uobd2.com, when I press this button, it says (This soft wear not installed
on this version). I want to know is the TEST icon means that it will give me
reports about the defects of the car or not. If it gives report I believe that
this will be easily for ordinary person.fficeffice" />
Please send to me a demo for the TEST soft wear to revise.
Also there is icon named Freeze frame, what does it mean?
