MODE DOOR MOTOR
COMPONENT DIAGNOSIS
MODE DOOR MOTOR
System Description
INFOID:0000000001547404
SYSTEM DESCRIPTION
Component Parts
Mode door control system components are:
• Front air control
• Mode door motor
• In-vehicle sensor
• Ambient sensor
• Sunload sensor
System Operation
The front air control receives data from each of the sensors. When a drive signal is input from front air control
to door motor, a step motor built into the door motor rotates according to the drive signal, and then stops at the
position of target door.
Mode door changes to instruction select mode by pressing MODE/DEF switch of the controller. That allows mode
door to be fixed.
Pressing AUTO switch allows automatic control by front air control, and mode door is fixed in the FOOT posi-
tion by pressing OFF switch.
During automatic operation of mode door, mode door position (VENT, B/L, FOOT) is selected according to the
temperature of discharge air calculated by front air control based on the target opening angle of air mix door
and the amount of sunload. And only when ambient temperature is extremely low with the mode door in the
FOOT position, D/F is selected and prevents windshield fogging.
