ING A/C CONTROL PANEL.
1) Turn the ignition switch from OFF to ACC,
and wait for 2 seconds.
2) Start the engine with the auto switch and
FRESH/RECIRC switch pressed.
NOTE:

TER
1) After the indicators stop blinking, automati-
cally change to the inspection mode of sensor
and potentiometer.
NOTE:
Display items can be changed each time the A/
C switch is pressed. (Step Operation)
2) When malfunction occurs in each sensor
and potentiometer, codes are displayed on the
screen. When no malfunction occurs in each
sensor and potentiometer, code “20” is dis-
played on the screen.
3) Identify the defective sensor according to
the sensor check table. SENSOR CHECK TABLE, OPERATION, Diag-
nostic Chart for Self-diagnosis.>
Are other codes except “20”
displayed?

ometer inspection, change to the inspection
mode of actuator, blower fan and magnet
clutch by pressing the defroster switch.
2) Each mode will change and operate auto-
matically every four seconds.
NOTE:
Operation mode items can be changed each
time the A/C switch is pressed. (Step Opera-
tion)
3) Check the operation of actuator, blower fan
and magnet clutch in each mode according to
the operating mode table. 14, OPERATING MODE TABLE, OPERATION,

Do the actuator, blower fan and
magnet clutch operate as
described in the operating
mode table?

NOTE:
When the sunload sensor check is performed indoors or in the shade, it could be diagnosed as having an
open circuit. Always check the sunload sensor with the sun shining on it.
*1: “AUTO” display does not blink when past malfunction occurred. Past malfunction means that abnormal signals were contin-
uously input for a certain time in the past.
*2: Present malfunction only is displayed for sunload sensor open circuit.
