Good morning everyone,
Forgive me but I am desperate.
My radiator fan is not working and I am afraid the relay is damaged.
Could someone tell me where it is or better yet give me a relay diagram?

The radiator fan is mechanically coupled via a viscous clutch to the aux belt so even if there is an electrical failure it will still run. If the fan is not working check the belt and viscous coupling. 2012 TDV8 Vogue (L322)

Which fan isn't working? is there an overheating issue?
If it's the electric fan, that is a 'boost' fan for the airconditioning condenser, which does have a relay (switched by the HVAC controller) if the variable viscous-coupled fan isn't working, which is directly controlled by a PWM signal from the ECM, this can be a failed speed sensor in the fan itself, reporting a high fan speed even though the fan itself may be barely moving. without a sufficient PWM signal and consequent fan lock-up, the fan will not move enough air to reduce the coolant temperature sufficiently at low speed or standstill.

Il problema di surriscaldamento compare solo quando sono in off road (bassa velocità e motore sotto sforzo).
Prima di cambiare il giunto viscoso che costa un rene vorrei essere certo che non sia un problema elettrico.
Come mi suggerite di agire? Quali passaggi devo fare prima di sostituire il giunto?
In realtà il Gap Id mi da errore P04080-13 (2f) fan 1 control circuit- general electric failure - circuit open.
Grazie in anticipo a chi perderà un po del Suo tempo per aiutarmi

The fault code points to an an electrical failure and specificaly a break in the circuit so trace it with a multimeter. I'm assuming that the fan spins but as Phoenix says it won't spin fast enough under load and low speed.
You can download circuit diagrams and the whole workshop manual with diagnostic and repair procedures from here (bottom of the page) https://www.fullfatrr.com/wiki/Main_Page 2012 TDV8 Vogue (L322)

Think that’s this…. Translated with internet… I don’t know Italian….

The overheating problem appears only when I am off road (low speed and engine under load).
Before changing the viscous joint that costs a kidney I would like to make sure it is not an electrical problem.
How do you suggest me to act? What steps should I take before replacing the joint?

The DTC suggests that there is no, or a high-resistance connection between the engine control module and pin 'D' on the fan connector, also check for a good ground connection on pin 'B' although if that was a concern, I'd expect to see DTC's related to lack of fan speed signal.

Grazie per i suggerimenti.
Vedrò di studiare bene il manuale e lo schema ettrico.
Il mio meccanico generico era già pronto a sostituire il giunto... Per fortuna esiste questo forum.
🙏🙏🙏🙏🙏

Sorry....

Thanks for the suggestions.
I will try to study well the manual and the scheme ettrico.
My general mechanic was already ready to replace the coupling... Luckily this forum exists.

It could still be the viscous coupling assembly, but you need to check the wiring mentioned above to eliminate that as the cause first.
