FUNCTION INSPECTION
1.
Press AUTO switch.
2.
“AUTO” is indicated on the display.
3.
Check that the indicator of the A/C switch turns on. Check visually and by sound that the compressor is
operating (the discharge air temperature or fan speed varies depending on the ambient temperature, in-
vehicle temperature, and temperature setting).
4.
Press the A/C switch.
5.
Check that the indicator of the A/C switch turns OFF. Check visually and by sound that the compressor
stops.
Does it operate normally?
YES
>> INSPECTION END
NO

(WITHOUT INTELLIGENT AIR CONDITIONER SYSTEM) or
HAC-159, "WITH INTELLIGENT AIR CONDI-
TIONER SYSTEM : CONSULT-III Function"
(WITH INTELLIGENT AIR CONDITIONER SYSTEM).
Is the inspection result normal?
YES
>> GO TO 7.
NO
>> Replace A/C auto amp.
7.

IONIZER
WITH INTELLIGENT AIR CONDITIONER SYSTEM
WITH INTELLIGENT AIR CONDITIONER SYSTEM : Description
INFOID:0000000003884785
Ionizer (1) is attached to the ventilator dust (RH) (2).
Ionizer has two types of operation mode and emits ions into the air
• Clean mode: Emits positive and negative ions at the same ratio.
• Ion control mode: Emits more negative ions.
WITH INTELLIGENT AIR CONDITIONER SYSTEM : Component Function Check
INFOID:0000000003884786
1.
CHECK IONIZER OPERATION SOUND
1.
Turn ignition switch ON.
2.
