rlan Posted May 24, 2015 Author Share Posted May 24, 2015 I tried 4 different types. One was a snap on scanner. I don't remember the others. Quote Link to comment Share on other sites More sharing options...
eugene.s Posted June 21, 2015 Share Posted June 21, 2015 Just returned from leave. You probably need to try professional scanners ($200+).The cheap ones (~$20) really often lose communication. Go to a dealer or AutoParts etc. The alternative is to pre-set whatever software coming with a cheap adapter to your particular market (US, Japan or Europe).

VBdenny Posted June 22, 2015 Share Posted June 22, 2015 Go to an AutoZone or Advance They have scanners you can use for free. Quote Link to comment Share on other sites More sharing options...
