Self-diagnosis Function
EJS00309
DESCRIPTION
The self-diagnostic system diagnoses sensors, door motors, blower motor, etc. by system line. Refer to appli-
cable sections (items) for details. Shifting from usual control to the self-diagnostic system is accomplished by
starting the engine (turning the ignition switch from OFF to ON) and pressing OFF switch for at least 5 sec-
onds. The “OFF” switch must be pressed within 10 seconds after starting the engine (ignition switch is turned
ON). This system will be canceled by either pressing A/C switch or turning the ignition switch OFF. Shifting
from one step to another is accomplished by means of turning temperature dial, as required.
Additionally shifting from STEP 6 to AUXILIARY MECHANISM is accomplished by means of pushing
(fan)
UP switch.

TROUBLE DIAGNOSIS
FUNCTION CONFIRMATION PROCEDURE
1.
SET IN SELF-DIAGNOSTIC MODE
Method 1 (Without navigation system, or with navigation system)
1.
Turn ignition switch to ON.
2.
Within 10 seconds after starting engine (ignition switch is turned ON.), press and hold OFF switch for at
least 5 seconds.
3.
The self-diagnosis (step 1) should start.
Method 2 (Only with navigation system)
1.
Turn OFF the audio system.
2.
While pressing “Vehicle Information” switch, turn audio switch (volume adjustment dial) by at least 30
notches.
3.
Trouble diagnosis initial screen appears. Using joystick, select “Confirmation and Adjustment”. And press
“Confirm”.
4.
Confirmation and adjustment initial screen appears. Using joystick, select “Air-conditioner trouble diagno-
sis”, and press “Confirm” to start self-diagnosis (step 1).
CAUTION:
If battery voltage drops below 12V during step diagnosis 3, actuator speed becomes slower and as a
result, the system may generate an error even when operation is normal. To avoid this, start engine
before performing this diagnosis.
