DTC B1442/42 Air Inlet Damper Control Servo Motor Circuit

DESCRIPTION

DTC Detecting Condition:

The air inlet control servomotor is controlled by the A/C amplifier assembly 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 assembly. This controls intake air and switches "RECIRCULATION", "FRESH" and "HALF-RECIRCULATION".
