MoeFleethandler Posted January 2, 2019 Share Posted January 2, 2019 Hi Truckers Need to help one of my clients to figure out the ECM port type on Mack Trucks (2014& over).I did a little bit of research and found out that all trucks would have a 16-pin ECM port. Need your thoughts on this, please? Quote Link to comment Share on other sites More sharing options...
Mackpro Posted January 3, 2019 Share Posted January 3, 2019 Mack now uses the OBD connector starting sometime in 2013. I believe some engine makers still use the round 9 pin connector though (Cummins). I saw a 2019 Mack GR with a Cummings in it and it had a round 9 pin connector for the engine and also the rectangle OBD connector for the vehicle ECU.

Even the newest Volvos with X15 Cummins have the 2 ports. Silly. Quote Link to comment Share on other sites More sharing options...
Mackpro Posted January 21, 2019 Share Posted January 21, 2019 (edited) Yea, back then they told us all trucks will use the OBD diag plug . I guess Cummins didn’t get the memo. Must just have to do with the vehicle/vehicle controls. Edited January 21, 2019 by Mackpro Quote Link to comment Share on other sites More sharing options...
JDS Posted April 16, 2022 Share Posted April 16, 2022 I am considering buying a 2017 Mack Pinnacle with a Mack 505 engine. I need to know if my Garmin elog will work with it. Garmin elog is not compatible with the obd2 j1979. Does anyone know what port is in a 2017 Pinnacle? Quote Link to comment Share on other sites More sharing options...
Dirtymilkman Posted April 17, 2022 Share Posted April 17, 2022 It should have both ports. But you better ask the seller to be safe. Quote Link to comment Share on other sites More sharing options...

Thank your lucky stars they don't build vehicles The engines are a big enough task for them! Volvo is bad enough ! 1 Quote Link to comment Share on other sites More sharing options...
