if you have a '06 you need version 9r 03 and do a reinstall by going in to options trouble shooting and and the idle shoud smooth out and i had injectors go bad and predator couldnt read either....so do the key cycle trick to see what cel you got.

had same problem with mine all of a sudden, took it to the shop and #1 injector was bad. replaced injector and it runs smooth again, well as smooth as a diesel can. i guess in 06 injectors were a common problem

Yeah for some reason 06's seems to display the injector problem more than any year.
