Wiring diagram for turning on the radiator fan of the Renault Duster cooling system

For active cooling of the radiator of the cooling system, as well as the radiator of the air conditioner, if there is one on the car, an electric fan is installed on the Renault Duster. The electric fan is turned on automatically. The electric fan can work with different modes. There are two such modes in total, that is, there are two possible nominal operating speeds of the electric fan. 
The main cause of electrical failure is blown fuses. Further in the article, a schematic diagram will be given and the fuses responsible for the operation of the electric fan will be indicated.

Two fuses installed in the engine compartment (62 and 61) are responsible for the operation of the electrical circuit. The control of turning on the electric fan is carried out from the signal coming from the electronic unit by the engine. The electronic unit controls the engine temperature by means of a temperature sensor (not shown in the diagram) and, if the rated operating temperature is exceeded, a signal will be given to turn on the electric fan.

Initially, power is supplied to the relay through contacts B1 and D4 (low speed), if the electric fan cannot cope in this mode, then the supply voltage is also applied to contact C1 (high speed of rotation of the electric fan).
