I just looked at it's capabilities and I think it would be fine......it shows to have system tests and bi directional controls along with obviously data and DTC functionality

Thanks. I have an old Tech2 but it just worked on the GM models. Nice unit but just too old now. I never had it updated just good up to 2002 I purchased the candi and 16 mb card but never installed them and now I don't even know how. Any ideas how to upgrade it?
