Cooling Fan for 2GR–FE
System Outline
System Operation
When the power SW is pushed to IG ON position (Power SW type), or when the ignition SW is turned to ON (Ignition SW
type), the current from the ECU IG NO.1 fuse is sent to the coil side and the FAN MAIN relay is turned to ON. Then the
current flows to TERMINAL 3 of the cooling fan ECU. At the same time, the conditions of the A/C SW, A/C pressure sensor,
engine coolant temp. sensor and engine rotation are sent to the TERMINAL 2 as signals from engine control module. As a
result of that, the cooling fan ECU continuously controls the rotation of the fan motor and keeps a balance between the
cooling efficiency and silentness with the optimal fan rotation.
