DESCRIPTION & OPERATION
The fan control module is powered from fusible link No. 2. (Схема №1) The ECM judges the required revolution speed of radiator fan motor and condenser fan motor using input signals transmitted from the A/C switch, automatic compressor controller, vehicle speed sensor and engine coolant temperature sensor. The ECM activates the fan control module to drive the radiator fan motor and condenser fan motor.
Technical Description
- The cause could be a malfunction of the fan control module power supply or ground circuit.
- The cause could also be a malfunction of the fan control module of the ECM.
The fan control module has variable control of the radiator fan motor and the condenser fan motor speeds using signals transmitted from the ECM.
