Things to note: Started after skid control went on in the rain while my daughter was driving. Has a brake fluid leak and was run low on fluid. Has not been bled since. (going to mechanic to solve the leak today.) Cleared the codes and they returned same day while I was at the car wash. Posted via the PriusChat mobile app.
