I have a 95 bonneville that has the OBD 2 port but when I hook up my Craftsman obd 1& 2 scan tool it will not connect.
I did not realize that it may have obd 1.5 and my scan tool will not work. I read the sticker next to the radiator and it does not say obd 2 certified, so I an assuming it is 1.5. Can anyone firm this and if so can I make a connect that will allow my current scan tool to work or do I need to buy another one? Is there an inexpensive 1.5 scan tool that will work? This pontiac is the only vehicle that maybe 1.5 all the other are either 1 or 2. Thanks
