I was driving to work this morning when this popped up where it usually displays my mileage. I was like 'huh?'.
I checked the one thing I thought it might be referring to but didn't see anything wrong. So I turned around and went home to look it up on the internets to see if my car was going to blow up or something.
It turns out my first thought was right. 9ASCAP means "GASCAP".
I guess a sensor died on it or something. Oh well, live and learn.
