Help me with the relay for cooling fan

Good morning everyone,
Can anyone tell me where I can find the relay that controls the engine cooling fan on the l322 tdv8 4.4?
I'm desperately looking for it
Thank you

I specify that I bought it but I don't know where it is in the engine compartment

According to the wiring diagram the cooling fan is directly controlled by the ECM.

From the WSM:

For additional airflow through the radiator matrix, particularly when the vehicle is stationary or slow moving, there is an
engine driven electro-viscous unit. This unit functions as a normal viscous fan, but with electronic control over the level of
engagement of the viscous clutch. The ECM , which determines the required fan speed, controls the level of clutch
engagement. The ECM determines engagement based on the coolant, ambient and transmission oil temperatures and A/C (air
conditioning) system pressure. The fan is mounted using a LH thread.
The viscous fan unit is electronically controlled by the ECM to optimise fan speed for all operating conditions.

Do you think the control unit acts directly on the viscous coupling without an intermediate relay? My problem arises only under load and off road: iidtool gives me error P 0480 - 13.
How can I check the wiring - does anyone have a schematic

Correct, there isn't a relay for the fan. It gets power from fuse 20 in the engine bay fuse box.

Hi, new the site and I’m having the same problem with the same code P0480-13. Was this issue fixed? Did you replace the viscous fan or was it electrical related?
