DTC B1443/43 Air Outlet Damper Control Servo Motor Circuit

DESCRIPTION

DTC Detection Condition:

The mode damper servo sends pulse signals to inform the air conditioner amplifier of the damper position.

The air conditioner amplifier activates the motor (normal, reverse) based on the signals to move the mode damper to any position, which controls the air outlet switching.

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