To the person who asked about OBDII for a Volvo. I believe all vehicles after 1996 have to, by Federal law, conform their data ports to the OBDII standard which is same for everybody. Thus a OBDII scanner should read any obdii vehicle. Go to: www.obdii.com for good info and a link to a scanner called AUTOTAP made by B&B for OBDII vehicles. regards, frank parker
