I got a flat tire a few weeks ago...My rear passenger side blew out after i ran over a pocket knife...a pocket knife! .....Anyway..Sure enough the screen told me the tire was at 0 PSI etc, etc.....BUT whats weird is that the screen thought it was the drivers side rear tire and NOT the passenger side...Maybe something in the OBDII sensors is reversed...I have no idea.
Mine was like that too until I "retrained" the system. Now it displays correctly. I verified by lowering the air pressure in the drivers side rear tire.
