DTC B1443 AIR OUTLET DAMPER CONTROL SERVOMOTOR CIRCUIT

CIRCUIT DESCRIPTION

Detection Item:

The mode damper servo sends pulse signals to inform the A/C amplifier of the damper position. The A/C 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.
