mines a 2002 pre facelift and I have been using my dealers(fiat) snap on machine with the port under the steering wheel. does this mean I need to use out older machine with the round connector to gain access to every code? or does my vehicle just have the one port? im a parts technician by the way not a mechanic just in case your thinking well you should know if you work for fiat. lol but I do get my hands dirty up to my skill limit.
