The knob to select the header height mode is not working. All I have is manual mode. No errors come up, and the height indicator is working so I'm guessing it's likely the knob switch. Just wondering if anyone else has had this issue, or if something else would cause this.
I will get by for wheat harvest (though it would be nice to have RTC), but really want the AHHC for beans this fall.

So I changed the knob switch and still nothing. Checked all fuses as well. Could really use some help on what my next step should be. Like I said, none of the functions work. Where should I look?

Anyone? Hate to have to go to the dealer for this but I'm out of ideas.

If you have header locked up for wheat the automatic wont work until you let back down to flex. Do you have any codes ? Is the header position showing correctly in the display ?

Do you have the sensitivity knob for the AHHC?

No codes. Yes the height display is working correctly. Even the return to cut did not work in the wheat. Just had to use the height gauge and manually bring the head down to the same height after each turn.

Yes.

Like I said, RTC does not work either so I don't think it's an AHHC circuit issue.
