Hello,
I have in workshop a 2018 Ford Custom with nonworking AC(AC_DMND is off in PCM data list evenif is on or off on HVAC).The pressure is ok(aprox 600KPa),no faults in HVAC but a lot of strange faults in PCM related to transmission even the car is equipped with manual transmission.I think PCM was rewrited ,not sure if as-built was corruped or not.
Please look at my attached files,any advice is wellcome.
Thank you

You have low battery codes, try clearing codes & see what comes back

Hello,
After clearing the fault codes related to low battery was not stored again.
Solved,my problem was fusebox with no contact on f28.
Best regards
