Diagnostictech Posted July 18, 2017 Share Posted July 18, 2017 Hey Guys, I am trying to figure out where the j1939 protocol is on a 2012 Mack truck. Does it have multiple port types and if so what are they and what is on each one? I know they switched port type around this time. Information about the truck below. What is the best way to get diagnostic port information on a bunch of different trucks? Help appreciated. Thanks VIN:1M2AV04CXCM008819 Manufacturer Mack Trucks, Inc.

Mackpro Posted July 18, 2017 Share Posted July 18, 2017 Yours shows to be the rectangle OBD connector. Should be right above where the clutch pedal should be( if you had one). Quote Link to comment Share on other sites More sharing options...
