Is it possible to get Mileage from odometer?

[Hesam]

Hey guys, I still have not bought Emulator yet but have a question first.

Based on my research it is not possible to get mileage of car from odometer, however, I guess this emulator is able to emulate that based on this image http://freematics.com/pages/wp-content/ ... common.png.
I'm confused!

Image shows there are two types on KM, "Distance traveled with MIL" and "Distance traveled since code cleared".
1- What does these two functions mean?
2- Are they referring to odometer?

Any suggestion would be appreciated. Thanks.

Thanks Stanley,

It's valuable reference.
I looked at the page and think "Distance traveled since code cleared" is the thing that I'm looking for.
Basically, I want to get distance between point A and point B. So I need to clear code at point A and read it at point B.

So my question is how to clear code? I actually don't understand what "clear code" means Is there any command to do that? Thanks.
