CONTROL SYSTEM
07-40–24
Correction
Warm-up correction
•
Controls the blower motor applied voltage
according to the increase in engine coolant
temperature to prevent discomfort caused by a
high volume of cold air blown from the vents in
winter after starting the engine. However, the
engine coolant temperature correction is not
performed when the target temperature is low,
and the airflow mode is in any mode other than
VENT mode.
Mild start correction
•
Limits blower motor applied voltage (front/rear) for
17 s after the blower motor is started in summer
to prevent discomfort caused by a high volume of
hot air blown from the vent. However, the mild
start correction is not performed when the airflow is in any mode other than VENT or BI-LEVEL, A/C mode is
OFF, or temperature of air passing through evaporator is low.
MAX HOT and MAX COLD correction
•
When the set temperature is at 32.0 , the blower motor applied voltage (front/rear) is fixed at AUTO-HI, and
when the set temperature is at 15.0 , the blower motor applied voltage (front/rear) is fixed at MAX-HI. However,
MAX HOT correction is not performed during warm-up correction.
Defroster correction
•
To improve defrosting of the windows, a correction ( +2 V ) is added to the front blower motor applied voltage
when the defroster switch is turned on.
Solar radiation correction
•
When the airflow mode is in VENT or BI-LEVEL, a
correction is added to the airflow volume
according to the amount of solar radiation.
