check engine- drive to workshop

[wanna986]

First off, my drive to the workshop got me nothing but sawdust. I don't want to to to the garage, though, as I'm sure the message is suggesting.

This popped up out of nowhere. The car is a 2002 S with 61K. The next time I started the engine- no message- I have the on-board computer.

Any suggestions? Was it possibly just a glitch that's reset itself? Any way of pulling codes?

Thanks in advance!
