COOLING FAN
Description
INFOID:0000000000956856
COOLING FAN CONTROL MODULE
Cooling fan control module receives ON/OFF pulse duty signal from IPDM E/R. Corresponding to this ON/OFF
pulse duty signal, cooling fan control module sends cooling fan motor operating voltage to cooling fan motor.
The revolution speed of cooling fan motor is controlled by duty cycle of the voltage.
COOLING FAN MOTOR
Cooling fan motor receives cooling fan motor operating voltage from cooling fan control module. The revolu-
tion speed of cooling fan motor is controlled by duty cycle of the voltage.
Component Function Check
INFOID:0000000000956857
1.
CHECK COOLING FAN FUNCTION
With CONSULT-III
1.
Turn ignition switch ON.
2.
Perform “FAN DUTY CONTROL” in “ACTIVE TEST” mode with CONSULT-III.
3.
Make sure that cooling fan speed varies according to the percent.
Without CONSULT-III
1.
Perform IPDM E/R auto active test and check cooling fan motors operation, refer to
.
2.
Make sure that cooling fan operates.
Is the inspection result normal?
YES
