Saw this posted over at the other board and was curious if anyone has been into this menu? What does the "tire Calibrate" do? The Diagnostic Screen

 

i imagine it's for if you put on new tires and enter the specs so the navi can still accurately measure distance and speed

 

if I was you, I wouldn't mess with that screen, you can really mess up the GPS Signals and Navigation and ETC..

 

I know you are asking for the TL but I think it uses the same computer as the TSX.

All I remember from the TSX is that it warns to NEVER adjust this setting - it is for factory use only.

If you're really interested I can look up the exact wording in the TSX shop manual.
