I have a '98 GM product that recently displayed the "check engine" light. On my older GM I just used jumpers to get a code. Now I'm told that one needs a diagnostic scanner to extract the codes (= hundreds of dollars).
Is there a clone of the OBD-II tester or some cheaper alternative?
I recall that there used to even be a harness and cheap software to hook up to your laptop to give one information. Does it still exist?
thanks in advance
