The working principle of cooling fan control module and its common fault symptoms:
The cooling fan control module is responsible for regulating the speed of the radiator cooling fan, thus controlling the engines cooling effect. The basic control principle involves the electronic control unit (ECU), control module, and temperature sensor.
The ECU receives the signal from the temperature sensor and uses this signal to control the fan control module, thereby achieving automatic control of the cooling fan.
- The fan cannot start.
- The fan keeps running or cannot be turned off.
- Temperature indication is abnormal.
- Engine overheating.
- Engine or cooling system malfunction light is on.
