Hello, I'm the proud owner of a 1997 Volvo V70 of which I want to read several things from the computer. I bought a fairly expensive OBD scanner tool that seems to support nearly all protocols. I was under the impression that my 1997 V70 could at least be partially read out with the 9141 or 9141-2 protocol. The scanner however cannot get any connection. I'm really clueless at this point on what to do next and I can't find a conclusive answer anywhere. Any help would be much appreciated.
