signal is output to the air mix actuator for
approx. every 5 min and malfunction
determination is performed.
After the IG SW is at ON, regular output of the
air mix actuator drive signal recommences.
Then a drive signal is output to the air mix
actuator
approx. every 5 min and malfunction
determination is performed.
Airflow mode actuator
(Motor lock)
Stops mode actuator drive signal at the point a
malfunction is determined. Then a drive signal
is output to the mode actuator
approx. every 5
min and malfunction determination is
performed.
After the IG SW is at ON, regular output of the
mode actuator drive signal recommences.
Then a drive signal is output to the mode
actuator
approx. every 5 min and malfunction
