D. Cooling fan and A/C compressor control
Conditions for cooling fan control ▶
The PWM cooling fan is set by coolant temperature and A/C refrigerant pressure. And, the setting value
in A/T equipped vehicle may vary according to the internal oil temperature. The The engine ECU
controls the PWM cooling fan unit based on various signals to get the optimized temperature during
engine running.
PWM cooling fan control according to coolant temperature and vehicle speed -
The PWM cooling fan starts running
from 89℃ of coolant temperature
PWM cooling fan control according to transmission fluid temperature (A/T)
1. PWM duty under 129℃: 0%
2. PWM duty over 130℃: 94.4% -
PWM cooling fan control according to A/C refrigerant pressure -
PWM duty value sharply increases
when the A/C refrigerant pressure goes
over 10 bar. And, it slowly decreases
when A/C refrigerant pressure goes
down below 14 bar (A/C compressor
OFF). PWM duty
Refrigerant pressure
(bar)under 101℃: The PWM duty value
decreases when the vehicle speed
increases
over 105℃: The PWM duty value
is fixed at 94.4% -
