Purpose
The air intake actuator moves the air intake door in the blower unit to switch the air intake port.
Function
The air intake actuator drives the motor based on the signal from the climate control unit and moves the air intake door to the FRESH or REC position.
Construction
A mechanical lock-type air intake actuator has been adopted.
The air intake actuator is installed to the blower unit.
Operation
1. The climate control unit outputs a motor drive signal to the air intake actuator based on the air intake mode determined by the air intake control.
2. When the air intake actuator moves to FRESH or REC, the motor locks.
3. When the motor locks and is under excessive load, the current value flowing from the climate control unit increases more than the specification (lock current).
4. When the lock current is detected, the climate control unit stops the motor drive signal to the air intake actuator.
Fail-safe
Function not equipped.
