OBD port

[nemo45]

Does any one know where the OBD port on a 2006 Tour Master T40 is or even if there is one on these diesels. I have a scan guage that I used on my gasser and I now would like to use it on the Tour Master.

The port where Freightliner connects computer to check for fault codes is in the rear by radiator on my 08 TM. There is a round grey cap that twists off. I have had both Freightliner and Cummins access that point.

Yep! On my Scenic Cruiser Freightliner Neway chassis it is on the extreme rear end. Lift the hood and there it is. Next to your vacuum gauge, leveler fluid reservoir, oil stick and a place where you can add fluid to your transmission when you change it out.
