  1. nethmina s prabha perera

    the nexas nl 102 obd scanner can i use the all heavy duty trucks hyundai hino volvo.scannia toyota,hino,waichai.any disel truks .actually is this multipurpose scannner

  2. Looking for a scanner that will connect to an 8 pin round port (3, 3, 2 holes). It’s for a 1991 Cummins (International dump truck). I’m trying to find a relatively inexpensive scanner/reader for my husband so he’s not at the mercy of waiting for someone to scan it when there’s an issue).

    1. Hi Shara,

      We believe that there is no 8-pin scanner for trucks. We recommend buying an adapter to convert 8-pin to 16-pin and choose NEXAS NL102 Plus or LAUNCH CReader HD Plus.

      You should also contact the manufacturer to confirm the compatibility.

      Best regards
