ok, I finally got into the diag display, I found the D62 option and it was in 01 value, I clicked the kill switch and it changed to 00 but it didn't changed anymore to any other option, not even the 01 again, so now is permanently on 00.
What did I changed? how can I get it back to 01?
By the way the temperature is still in ºF
Thanks for your help
