Diagnosis Procedure
INFOID:0000000010432246
NOTE:
Perform self-diagnoses with CONSULT before performing symptom diagnosis. If any DTC is detected, per-
form the corresponding diagnosis.
1.

1.
Check engine coolant level and check for leakage. Refer to
els),
(MR20DD engine models),
(R9M engine models).
2.
Check reservoir tank cap. Refer to
(MR20DD engine models),
(R9M engine
models).
3.
Check water flow sounds of the engine coolant. Refer to
(MR20DD engine models),

(K9K and R9M engine models except for Europe).
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: GO TO 6.
NO
>> Repair or replace parts depending on the inspection results.
5.
CHECK PTC HEATER
Perform PTC heater diagnosis. Refer to
