Hey guys I'm new at this so bear with me.. I have 2003 Saab 9-3t and a tech 2 clone with a PC that has tis2000 from eBay. I can communicate with the tech 2 and PC but can't communicate with my car at all. I get an error that it can't link with ECM. I did a tech 2 self test and everything passes but RTC. And I did the Candi test: passes the 1st test but at the second test it fails high speed data link. Is this normal?
