38 front and 41 back is when you have 2+ people plus lugagge. Its a weight mesure.
if that is what u want. Its ok.
and the mesure in the dash can be reset to the value you want. Soo you that screen with the -1 is for
what i had reset your psi stats to.

you should set your 2 front to 38 and 2 back to 41 then reset your mesure in dash. Then your all set

The PCM has a setting for comfort, full load, etc., which aetting do you have.

That's the one you need to follow, because it uses those settings for tire pressure warnings.
