Discuss the causes and fixes for P0600 Subaru OBDII Code

  • 2006 Subaru Outback Sport. Started vehicle the other day and a crap load of panel lights lit up, a bit startled, I pulled over right away and shut it off. Restarted and only the check engine light remained on. Drove the very short distance back home and had it towed to the garage (not a dealership). They fixed the heat shields (which I knew needed to be done) and reported these diagnostic codes which they had no access to: PO600, PO700 and P1718. My next step is to take it to the dealership and I will report back
