INSUFFICIENT HEATING
INSUFFICIENT HEATING
Description
INFOID:0000000010939870
Symptom
• Insufficient heating
• No warm air comes out. (Air flow volume is normal.)
Diagnosis Procedure
INFOID:0000000010939871
NOTE:
Perform self-diagnoses with CONSULT before performing symptom diagnosis. If any DTC is detected, per-
form the corresponding diagnosis.
1.
CHECK COOLING SYSTEM
1.
Check engine coolant level and check for leakage. Refer to
(MR20DD engine mod-
els) or
(R9M engine models).
2.
Check radiator cap or reservoir tank cap. Refer to
CO-16, "RADIATOR CAP : Inspection"
(MR20DD
engine models) or
(R9M engine models).
3.
Check water flow sounds of the engine coolant. Refer to
(R9M engine models).
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Refill engine coolant and repair or replace the parts depending on the inspection results.
2.
CHECK HEATER HOSE
Check installation of heater hose by visually or 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 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-46, "HEATER CORE : Removal and Installation"
(R9M engine
models except for Europe) or
HA-91, "HEATER CORE : Removal and Installation"
(MR20DD
engine models).
4.
CHECK AIR LEAKAGE FROM EACH DUCT
Check duct and nozzle, etc. of the air conditioning system for air leakage.
Is the inspection result normal?
YES-1 >> With PTC heater: GO TO 5.
YES-2 >> Without PTC heater: INSPECTION END
NO
>> Repair or replace parts depending on the inspection results.
5.
CHECK PTC HEATER
Perform PTC heater diagnosis. Refer to
HAC-115, "Diagnosis Procedure"
.
Is the inspection result normal?
YES
>> INSPECTION END
NO
>> Repair or replace parts depending on the inspection results.
