Yesterday my Brake and Battery dash warning lights came on for a few minutes, then went off. They did it again a little while later, then I didn't notice them again for the rest of the day.

Today they are steady on. Drove to work this morning and both warning lights were on for the entire 35 min. drive.
I haven't noticed any symptoms yet.

Any ideas? How can I pull the computer error codes?
