DTC B1443/43 Air Outlet Damper Control Servo Motor Circuit

DESCRIPTION

DTC Detection Condition:

The mode damper servo motor sends pulse signals to inform the air conditioning amplifier of the damper position. The air conditioning amplifier activates the motor (normal, reverse) based on the signals to move the air outlet damper to any position, which controls the air outlet switching.

HINT: Confirm that no mechanical problem is present because this diagnostic trouble code can be output when either a damper link or damper is mechanically locked.
