DTC B1444/44 Driver Side Cool Air Bypass Damper Control

DESCRIPTION

DTC Detection Condition:

The damper servo (for driver side cool air bypass) 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 damper servo (for driver side cool air bypass) to any position. As a result, when the air conditioner is operating, the temperature of the air blowing toward the driver's head area is controlled.

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