OUT INTELLIGENT AIR CONDITIONER SYSTEM) or HAC-159, "WITH INTELLIGENT AIR CONDI-
TIONER SYSTEM : CONSULT-III Function" (WITH INTELLIGENT AIR CONDITIONER SYSTEM).
NOTE:
Perform the ACTIVE TEST after starting the engine because the compressor is operated.
2. Check that the blower motor control signal changes according to each indicator signal.
NOTE:
 Perform the inspection of each output device after starting the engine because the compressor is oper-
ated.
 When choosing to “MODE 7”, error message is displayed but it is not malfunction.
Does it operate normally?
YES >> INSPECTION END
NO >> GO TO 3.
3.CHECK POWER SUPPLY FOR BLOWER MOTOR
1. Disconnect blower motor connector.
2. Turn ignition switch ON.
3. Check voltage between blower motor harness connector and ground.
Is the inspection result normal?
YES >> GO TO 4.
NO >> GO TO 7.
4.CHECK BLOWER MOTOR GROUND CIRCUIT
1. Turn ignition switch OFF.
2. Check continuity between blower motor harness connector and ground.
Is the inspection result normal?
YES >> GO TO 5.
NO >> Repair harness or connector.
5.CHECK BLOWER MOTOR CIRCUIT CONTINUITY
1. Disconnect A/C auto amp. connector.
2. Check continuity between blower motor harness connector and A/C auto amp. harness connector.

5.CHECK WITH SELF-DIAGNOSIS FUNCTION OF CONSULT-III
1. Using CONSULT-III, perform “SELF-DIAGNOSIS RESULTS” of HVAC.
2. Check if any DTC is displayed in the self-diagnosis results.
NOTE:
If DTC is displayed along with DTC U1000 or U1010, first diagnose the DTC U1000 or U1010. Refer to HAC-
164, "DTC Logic" or HAC-165, "DTC Logic".
Is any DTC displayed?
YES >> Perform the diagnosis that is applicable to the sensor and actuator. Refer to HAC-212, "WITH-
OUT INTELLIGENT AIR CONDITIONER SYSTEM : DTC Index" (WITHOUT INTELLIGENT AIR
CONDITIONER SYSTEM) or HAC-224, "
WITH INTELLIGENT AIR CONDITIONER SYSTEM :
DTC Index" (WITH INTELLIGENT AIR CONDITIONER SYSTEM).
NO >> GO TO 6.
6.CHECK A/C AUTO AMP. INPUT SIGNAL
Using CONSULT-III, check “On/Off” of “AIR COND SIG” and “HEATER FAN SW” in “DATA MONITOR” of
HVAC. Refer to HAC-156, "
WITHOUT INTELLIGENT AIR CONDITIONER SYSTEM : CONSULT-III Function"
(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.CHECK REFRIGERANT PRESSURE SENSOR
Check refrigerant pressure sensor. Refer to EC-348, "
Diagnosis Procedure".
Is the inspection result normal?
YES >> INSPECTION END
NO >> Repair or replace malfunctioning parts.A/C SWITCH ON : AIR COND SIG On
A/C SWITCH OFF : AIR COND SIG Off

IONIZER
WITH INTELLIGENT AIR CONDITIONER SYSTEM
WITH INTELLIGENT AIR CONDITIONER SYSTEM : DescriptionINFOID: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. Press AUTO switch.
3. Ion indicator (blue) is shown on the display.
4. Check the ionizer operation sound (whirring sound) in the duct by putting an ear to the center ventilator
grille (RH) outlet.
Is the inspection result normal?
YES >> END.
NO >> Go to Diagnosis Procedure. Refer to HAC-199, "
WITH INTELLIGENT AIR CONDITIONER SYS-
TEM : Diagnosis Procedure".
WITH INTELLIGENT AIR CONDITIONER SYSTEM : Diagnosis ProcedureINFOID:0000000003884787
1.CHECK POWER SUPPLY FOR IONIZER
1. Turn ignition switch OFF.
2. Disconnect ionizer connector.
3. Turn ignition switch ON.
4. Check voltage between ionizer harness connector and ground.
Is inspection result normal?
YES >> GO TO 2.
NO >> Check 10A fuse (No. 3, located in the fuse block). Refer to PG-101, "
Fuse, Connector and Ter-
minal Arrangement".
 If fuse is OK, check harness for open circuit. Repair or replace if necessary.
 If fuse is NG, replace fuse and check for short circuit. Repair or replace if necessary.
2.CHECK ION ON/OFF OUTPUT SIGNAL
1. Turn fan control dial clockwise.
2. Check voltage between ionizer harness connector and ground.
