DTC B1459/59 Max Hot Bypass Damper HOT Control Circuit

DESCRIPTION

DTC Detection Condition:

The max hot bypass damper servo motor (for HOT) 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 max hot bypass damper servo motor (for HOT) 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 a damper link or damper is mechanically locked.
