DTC B1448/48 Passenger Side FACE Servo Motor Circuit

DESCRIPTION

DTC Detection Condition:

The mode damper servo (for passenger side FACE) 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 mode damper servo (for passenger side FACE) to any position, which controls the air outlet changes.

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.
