DESCRIPTION

DTC Detecting Condition:




The air inlet control servomotor is controlled by the A/C amplifier and moves the air inlet control servo motor to the desired position.

The air inlet control servo motor switches between "RECIRCULATION" and "FRESH" by rotating the motor (normal, reverse) with electrical power from the A/C amplifier. This controls intake air and switches "RECIRCULATION", "FRESH" and "HALF-RECIRCULATION".
