Hi friends 
Could anyone please help me out with ecu 2.0diesel and ac wiring diagram can’t find anything… its 2011 
Ac works after start for five seconds even fan get on than shut all off 
There is new resistor for fan new ac pressure switch newly added refrigerant 
Thanks
I would like to check the pressure sensor wiring I got one with 5V I can also see on data pressure so I think the one with 5v and one with signal works what I don’t know the third for low signal
Thanks given by:
