Last Monday I posted a message titled "OK to drive 9000 with CHECK ENGINE on?" both in this newsgroup and in the Saab Network Bulletin Board, http:www.saabnet.com/tsn/bb/. One of the replies in the Board (the one by BobS...thanks BobS!) gives the different flash codes, the surrounding context, and reset information. I would guess that "one long flash" you observed is the 3 second marker. And if BobS has given correct information, the four short flashes (which happens to also be my case) indicate "coolant temperature sensor". I did not see flash code information in Haynes. I'm disappointed that Haynes left this out. So, now I will try to follow Haynes to see if I can locate the coolant temperature sensor, if there is easy access to it without having to disassemble anything, and if I can test its resistance in place (without having to remove it and consequently drain the cooling system) against the Specifications in Haynes.
