When performing indoors, aim a light (more than 60W) at sunload
sensor, otherwise LED of rear window defogger switch will illuminate
despite that sunload sensor is functioning properly.

Door motor corresponding to the DTC
DTC for an inoperative harness
If a corresponding door motor blinks, set mode control dial to appropriate position to check each door motor.
NOTE:
• If all four terminals of each door motor show an open circuit, there is probably a disconnected connector or
an open circuit in door motor drive power supply harness.
• If a short circuit occurs in harness between terminals for each door motor drive signal, although it cannot be
detected by self-diagnosis, door motor will vibrate when it operates.

System Description
INFOID:0000000001547326
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 manual select mode by turning mode control dial 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 blow-off wind calculated by front air control based on the target opening angle of air mix door
and the amount of solar radiation. And only when ambient temperature is extremely low with the mode door in
the FOOT position, D/F is selected and prevents windshield fogging.
