< FUNCTION DIAGNOSIS >[AUTO AIR CONDITIONER (W/NAVI)]
SELF-DIAGNOSIS FUNCTION
Go to Magnet Clutch Circuit. Refer to HAC-239, "Magnet Clutch Diagnosis Procedure".
9.CHECK MALFUNCTION SENSOR
Refer to the following chart.
*1: Perform self-diagnosis STEP-2 under sunshine.
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.
*2: HAC-244, "
Ambient Sensor Diagnosis Procedure".
*3: HAC-247, "
In-Vehicle Sensor Diagnosis Procedure".
*4: HAC-253, "
Intake Sensor Diagnosis Procedure".
*5: HAC-250, "
Sunload Sensor Diagnosis Procedure".
*6: HAC-226, "
Air Mix Door Motor Diagnosis Procedure".
*7: HAC-222, "
Mode Door Motor Diagnosis Procedure".
*8: HAC-230, "
Intake Door Motor Diagnosis Procedure".
In case of a break in the ambient sensor, front air control regards ambient temperature as extreme cold
(approximately –42°C or less) and then start warming.

10.CHECK MALFUNCTION DOOR MOTOR POSITION SWITCH
Usual: LED for A/C switch and intake switch turn ON.
Unusual: LED for malfunctioning door motor blinks. If unusual condi-
tions are detected in multiple door motor-positions, appropriate
switch LED blink twice respectively.

< FUNCTION DIAGNOSIS >[AUTO AIR CONDITIONER (W/NAVI)]
SELF-DIAGNOSIS FUNCTION
 Pressing the rear window defogger switch during STEP-3 will send
a reset signal to air mix door and mode door motor to reset them to
the starting position.
During reset: The rear window defogger switch LED will blink,
(approx. 10 seconds) Intake switch and A/C switch LEDs will blink.
(For approx. 6 seconds)

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.

SYSTEM DESCRIPTION
Component Parts
Air mix door control system components are: Front air control
 Air mix door motor
 In-vehicle sensor
 Intake sensor
 Ambient sensor
 Sunload sensor
System Operation
The front air control receives data from each of the sensors. When setting a target temperature by using tem-
perature button, front air control corrects preset temperature, performs an arithmetical operation based on sig-
nals from sensors and determines opening angle of target air mix door.
Air mix door is constantly controlled so as to keep optimum opening angle of air mix door based on target and
present opening angles of air mix door. Air mix door is fixed in the full cold position when preset temperature is
set to 18°C, and full hot position when set to 32°C.
Drive System of Step Motor Type Door Motor
 Motor is actuated in sequence by energizing four drive coils.
 Rotation direction can be changed by changing pattern of excitation.
