Can anyone please advise - My 2002 Saab 9-3 TID starts and runs from cold no problems, If i stop it when warm and try to re-start it cranks but wont fire. Cheap OBD2 reader gives code P0607 Control Module Fault. I've changed the crank shaft sensor and still the same. Please help as it's having my life.
Good news is the ECM is inside the passenger compartment and it shouldn't have a heat related problem so it might just need reprogramming. Bad news is the diesel injector module is engine mounted and could very easily have succumbed to heat. You will need a Tech 2 if cleaning the ground points and reseating the cables doesn't cure the problem.
Don't know enough about how Saab controls a diesel to know if this will help, but pulling the ECM fuse to reset the engine controller does clear the 607 code and if that doesn't get you going until the next time, you can always try resetting the injector module pulling the fuse. Doing this won't fix anything, but it could make life a bit easier.
Thanks Digger, I've found a Tech 2 OBD2 plug in thingy and disk on ebay. I'll give this ago sometime next week when I have time. Handy knowing about the location of ECM and fuse stuff.
I'll keep you updated. Thanks again.
