Anybody know how to put our EATC into self test mode to see if there are any diagnostic codes? Also then what each code would mean? I did this for my 10th gen but I cant find out how to or if I can do this now with my 11th gen. Can't do any testing under the hood till the weekend but I thought I'd see if there are any code in the EATC first.

May have found some info but I'll take more if someone else has more. https://www.justanswer.com/ford/2o4v...ls-moving.html

To enter the self-test, press the OFF and DEFROST buttons simultaneously and release, then press the AUTO button within 2 seconds. The display will show a flashing blower icon for 20 seconds, after which all vacuum fluorescent segments will be displayed if there are no on-demand DTCs present. If DTCs are present, the HVAC module - EATC will display "00 00" and then on-demand DTCs. Record all DTCs displayed

Thanks again. I will check back in later today when I get a chance to test it.

I think the process described in the link is for older models, though I'd imagine the codes remain the same. Good luck

Well I tried this method and it would not go into self test mode. Guessing this doesn't work for 11th gens.

Hmm....try and off and floor, instead of defrost

Shoot I did try off and floor. I'll try off and defrost later.
