Diagnosis Procedure
Note:
Perform self-diagnoses with consult before performing symptom diagnosis. If any dtc is detected, perform the corresponding diagnosis.
1.Check magnet clutch operation
Is the inspection result normal? Yes >> go to 2.
No >> perform diagnosis of “compressor does not operate” in “symptom diagnosis”.
Refer to hac-102, "diagnosis procedure".
2.Check drive belt
Check tension of drive belt. Refer to em-16, "inspection".
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-18, "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 ambient temperature display
Check that there is not much difference between actual ambient temperature and indicated temperature on information display in combination meter.
Is the inspection result normal? Yes >> go to 6.
No >> perform diagnosis for the a/c auto amp. Connection recognition signal circuit. Refer to hac-63, "diagnosis procedure".
6.Check setting of temperature setting trimmer (front)
Note:
The control temperature can be set with the setting of the temperature setting trimmer (front).
Is inspection result normal? YES >> Inspection End.
NO >> Replace A/C auto amp. Refer to HAC-105, "Removal and Installation".
INSUFFICIENT HEATING
Description
Symptom
Diagnosis Procedure
Note:
Perform self-diagnosis with consult before performing symptom diagnosis. If dtc is detected, perform the corresponding diagnosis.
1.Check cooling system
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
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-44, "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)
Note:
The control temperature can be set by the temperature setting trimmer (front).
Are the symptoms solved? Yes >> inspection end.
No >> replace a/c auto amp. Refer to hac-105, "removal and installation".
COMPRESSOR DOES NOT OPERATE
Description
Symptom: compressor does not operate.
Diagnosis Procedure
Note:
1.Check magnet clutch operation
Check magnet clutch. Refer to HAC-94, "Component Function Check".
Does it operate normally? YES >> GO TO 2.
NO >> Repair or replace malfunctioning parts.
2.Check refrigerant pressure sensor
Check refrigerant pressure sensor. Refer to EC-465, "Component Function Check".
Is the inspection result normal? YES >> GO TO 3.
NO >> Repair or replace malfunctioning parts.
3.Check A/C Auto AMP. Output signal
With CONSULT
Check “COMP REQ SIG” and “FAN REQ SIG” in “DATA MONITOR” mode of “HVAC” using CONSULT.
Is the inspection result normal? YES >> GO TO 4.
NO >> Replace A/C auto amp. Refer to HAC-105, "Removal and Installation".
4.Check ecm input signal
With CONSULT
Check “AIR COND SIG” and “HEATER FAN SW” in “DATA MONITOR” mode of “ECM” using CONSULT.
Is the inspection result normal? YES >> GO TO 5.
NO >> Check CAN communication system. Refer to LAN-16, "Trouble Diagnosis Flow Chart".
5.Check IPDM E/R Input signal
With CONSULT
Is the inspection result normal? YES >> Inspection End.
NO >> Check CAN communication system. Refer to LAN-16, "Trouble Diagnosis Flow Chart".
