I have an internal check sum memory error to the ECU on my 2003 Saab 9-3, P0601. When this code pops on my car, the vehicle is totally inoperable and shuts down until fuse f2 on the engine bay fuse panel is removed and reinstalled (its not blown, just removes power from and resets the ecu). After resetting the ECU I got 600 miles before it tripped again, now it is very frequent, sometimes not lasting a mile. Needless to say, its parked and deemed not roadworthy until this problem is resolved.
These ECU's are not over the counter parts at my local parts houses so I am considering a donor part. If I replace the ECU from a donor car (same year, transmission, engine), will it have to be programmed specifically for my car? Also, Is the Memory part of the ECU, or a seperate part all together?
I have heard that the key fob will not function along with other quirks that go along with donor parts that are not programmed for your car specifically? I thought it best to ask before I purchase a donor ECU, and find out I should have folded to dealer parts to begin with.
Thanks in advance for your help.
have the same problem?
