HAC-100, "Diagnosis Procedure"

.

2.

CHECK DRIVE BELT

Check tension of drive belt. Refer to 

EM-15, "Checking"

.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Adjust or replace drive belt depending on the inspection results.

3.

CHECK REFRIGERANT CYCLE

Connect recovery/recycling recharging equipment to the vehicle and perform pressure inspection with gauge.

Refer to 

HA-17, "Symptom Table"

.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair or replace parts depending on the inspection results.

4.

CHECK AIR LEAKAGE FROM EACH DUCT

Check duct and nozzle, etc. of the front air conditioning system for leakage.
Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Repair or replace parts depending on the inspection results.

5.

CHECK SETTING OF TEMPERATURE SETTING TRIMMER (FRONT)

1. Check setting value of temperature setting trimmer (front). Refer to 

HAC-50, "Temperature Setting Trim-

mer"

. 

2. Check that temperature setting trimmer (front) is set to “+ direction”. 

NOTE:

The control temperature can be set with the setting of the temperature setting trimmer (front).

3. Set difference between set temperature and control temperature to “0”.
Is inspection result normal?

YES

>> Inspection End.

NO

>> Replace A/C auto amp. Refer to 

HAC-103, "Removal and Installation"

.

INSUFFICIENT HEATING

Description

INFOID:0000000011276644

Symptom

• Insufficient heating

• No warm air comes out. (Air flow volume is normal.)

Diagnosis Procedure

INFOID:0000000011276645

NOTE:

Perform self-diagnosis with CONSULT before performing symptom diagnosis. If DTC is detected, perform the

corresponding diagnosis.

1.

CHECK COOLING SYSTEM

1. Check engine coolant level and check leakage. Refer to 

CO-8, "Inspection"

.

2. Check reservoir tank cap. Refer to 

CO-12, "RADIATOR CAP : Inspection"

.

3. Check water flow sounds of the engine coolant. Refer to 

CO-8, "Inspection"

.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Refill engine coolant and repair or replace parts depending on the inspection results.

2.

CHECK HEATER HOSE

Check installation of heater hose visually or by touching.
Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair or replace parts depending on the inspection results.

3.

CHECK HEATER CORE

1. Check temperature of inlet hose and outlet hose of front heater core.

2. Check that inlet side of heater core is hot and the outlet side is slightly lower than/almost equal to the inlet

side.

CAUTION:

Always perform the temperature inspection in a short period of time because the engine coolant

temperature is very hot.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Replace heater core. Refer to 

HA-43, "HEATER CORE : Removal and Installation"

.

4.

CHECK AIR LEAKAGE FROM EACH DUCT

Check duct and nozzle, etc. of front air conditioning system for air leakage.
Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Repair or replace parts depending on the inspection results.

5.

CHECK SETTING OF TEMPERATURE SETTING TRIMMER (FRONT)

1. Check setting value of temperature setting trimmer (front). Refer to 

HAC-50, "Temperature Setting Trim-

mer"

. 

2. Check that temperature setting trimmer (front) is set to “

− direction”. 

NOTE:

The control temperature can be set by the temperature setting trimmer (front).

3. Set difference between the set temperature and control temperature to “0”.
Are the symptoms solved?
