SELF-DIAGNOSIS FUNCTION
5. Set in self-diagnostic mode as follows. Within 10 seconds after starting engine (ignition switch is turned
ON.), press intake switch for at least 5 seconds.
CAUTION:
If battery voltage drops below 12V during diagnosis STEP-3, door motor speed becomes slower and
as a result, the system may generate an error even when operation is usual. To avoid this, start engine
before performing this diagnosis.

Discharge Air Flow"), air temperature, blower motor voltage,
and A/C compressor operation.
Checks must be made visually, by listening to any noise, or by touching air outlets with your hand, etc. for
improper operation.
OK or NG
OK >> INSPECTION END
NG >>  Air outlet does not change.
Go to Mode Door Motor Circuit. Refer to HAC-222, "
Mode Door Motor Diagnosis Procedure".
 Intake door does not change.
Go to Intake Door Motor Circuit. Refer to HAC-230, "
Intake Door Motor 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, "

*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.
>> INSPECTION END
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.

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)

COMPONENT DIAGNOSIS
MODE DOOR MOTOR
System DescriptionINFOID: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.

MODE DOOR MOTOR
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.
Mode Door Control Specification
COMPONENT DESCRIPTION
Mode Door Motor
The mode door motor is attached to the A/C unit assembly. It rotates
so that air is discharged from the outlet set by the front air control
Motor rotation is conveyed to a link which activates the mode door.
