Hello everyone,


Does anyone know where the relays for the Frontfans are located?


Background:
I’m increasingly getting the following fault codes:


Code – Meaning
P0693 – Fan motor 2 – circuit low
P0691 – Fan motor 1 – circuit low
U1400 – Invalid or missing signal from a control unit (CAN communication)
P0495 – Fan running at too high speed
P2291 – Injection pressure too low during start


I would be really grateful for help, have been some hours on the problem...
