Yeah we actually sent it out to a desiel shop who cleans dpfs it was plugged with mud apparently. Not the fist part of the truck plugged with mud either. Anyways got it back did a scan cleared the code and she was good to go. Ran the pi55 out of it to make sure she was good.

the data connector is under the cup holder, however with the perkins engine you need to have the cat adapter 3 and the est software to connect to the engine. you will need to clean the entire emissions system and verify the egr function in order to get that code cleared. also dont forget to clean the pressure sense tubes. the real question is why the dpf clogged in the first place, if you have a aftermarket diag tool with 16 pin j1939 it might connect but thats a slim chance.
