< SYMPTOM DIAGNOSIS >[WITH 7 INCH DISPLAY]
INSUFFICIENT COOLING
INSUFFICIENT COOLING
DescriptionINFOID:0000000003884801
Symptom
 Insufficient cooling
 No cool air comes out. (Air flow volume is normal.)
Inspection procedureINFOID:0000000003884802
1.CHECK WITH A GAUGE OF RECOVERY/RECYCLING RECHARGING EQUIPMENT
Connect the recovery/recycling recharging equipment to the vehicle and perform the pressure inspection with
the gauge.
Is there refrigerant?
YES >> GO TO 2.
NO-1 >> Check for refrigerant leakages with the refrigerant leakage detecting fluorescent leak detector.
Refer to HA-32, "
Inspection".
NO-2 >> GO TO 2 after repairing or replacing the parts according to the inspection results.
2.CHECK CHARGED REFRIGERANT AMOUNT
1. Connect recovery/recycling recharging equipment to the vehicle and discharge the refrigerant.
2. Recharge with the proper amount of refrigerant and perform the inspection with the refrigerant leakage
detecting fluorescent leak detector. Refer to HA-32, "
Inspection".
Is the inspection result normal?
YES >> GO TO 3.
NO >> Refill the refrigerant and repair or replace the parts according to the inspection results.
3.CHECK REFRIGERANT CYCLE PRESSURE
Connect recovery/recycling recharging equipment to the vehicle and perform the performance test. Refer to
HA-30, "
Performance Chart".
Is the inspection result normal?
YES >> GO TO 4.
NO >> Perform the diagnosis with the gauge pressure. Refer to HA-8, "
Trouble Diagnosis For Unusual
Pressure".
4.CHECK SETTING OF TEMPERATURE SETTING TRIMMER
Using CONSULT-III, check the setting of “TEMP SET CORRECT” on “WORK SUPPORT” of HVAC. Refer to
HAC-110, "
WITHOUT INTELLIGENT AIR CONDITIONER SYSTEM : Temperature Setting Trimmer" (WITH-
OUT INTELLIGENT AIR CONDITIONER SYSTEM) or HAC-114, "
WITH INTELLIGENT AIR CONDITIONER
SYSTEM : Temperature Setting Trimmer" (WITH INTELLIGENT AIR CONDITIONER SYSTEM).
1. Check that the temperature setting trimmer is set to “+ direction”.
NOTE:
The control temperature can be set with the setting of the temperature setting trimmer.
2. Set temperature control dial to “0”.
Are the malfunction solved?
YES >> Perform the setting separately if necessary. END.
NO >> GO TO 5.
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 trouble 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 the door motor. Refer to HAC-212,

Symptom
 Insufficient heating
 No warm air comes out. (Air flow volume is normal.)
Inspection procedureINFOID:0000000003884804
1.CHECK COOLING SYSTEM
1. Check engine coolant level and check for leakage. Refer to CO-8, "
Inspection".
2. Check radiator cap. Refer to CO-12, "
RADIATOR CAP : Inspection".
3. Check water flow sounds of engine coolant. Refer to CO-9, "
Refilling".
Is the inspection result normal?
YES >> GO TO 2.
NO >> Refill the engine coolant and repair or replace the parts according to the inspection results.
2.CHECK OPERATION
1. Press temperature control dial (driver side) and raise temperature setting to 32°C (90°F) after warming up
the engine.
2. Check that warm air blows from the outlets.
Is the inspection result normal?
YES >> END.
NO >> GO TO 3.
3.CHECK SETTING OF TEMPERATURE SETTING TRIMMER
Using CONSULT-III, check the setting of “TEMP SET CORRECT” on “WORK SUPPORT” of HVAC. Refer to
HAC-110, "
WITHOUT INTELLIGENT AIR CONDITIONER SYSTEM : Temperature Setting Trimmer" (WITH-
OUT INTELLIGENT AIR CONDITIONER SYSTEM) or HAC-114, "
WITH INTELLIGENT AIR CONDITIONER
SYSTEM : Temperature Setting Trimmer" (WITH INTELLIGENT AIR CONDITIONER SYSTEM).
1. Check that the temperature setting trimmer is set to “− direction”.
NOTE:
The control temperature can be set by the temperature setting trimmer.
2. Set temperature control dial to “0”.
Are the malfunction solved?
YES >> Perform the setting separately if necessary. END.
NO >> GO TO 4.
4.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 trouble 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 the door motor. Refer to HAC-212,
"WITHOUT INTELLIGENT AIR CONDITIONER SYSTEM : DTC Index" (WITHOUT INTELLI-
GENT AIR CONDITIONER SYSTEM) or HAC-224, "
WITH INTELLIGENT AIR CONDITIONER
SYSTEM : DTC Index" (WITH INTELLIGENT AIR CONDITIONER SYSTEM).
NO >> GO TO 5.
5.CHECK WITH ACTIVE TEST OF CONSULT-III
1. Using CONSULT-III, perform “HVAC TEST” in “ACTIVE TEST” of HVAC to check each output device.
Refer to HAC-156, "
WITHOUT INTELLIGENT AIR CONDITIONER SYSTEM : CONSULT-III Function"
(WITHOUT INTELLIGENT AIR CONDITIONER SYSTEM) or HAC-159, "WITH INTELLIGENT AIR CON-
DITIONER SYSTEM : CONSULT-III Function" (WITH INTELLIGENT AIR CONDITIONER SYSTEM).
NOTE:
