Inspection Procedure

INSUFFICIENT COOLING


Inspection procedure

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 Fluorescent Leak Detector.
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. Refer to
Refrigerant.
2. Recharge with the proper amount of refrigerant. Refer to Refrigerant.
3. Perform the inspection with the refrigerant leakage detecting fluorescent leak detector. Refer to Fluorescent Leak Detector, "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.PERFORM THE PERFORMANCE TEST
Connect recovery/recycling recharging equipment to the vehicle and perform the performance test. Refer to Performance Chart.
Is the inspection result normal?
YES - GO TO 4.
NO - Perform the diagnosis with the gauge pressure. Refer to Trouble Diagnosis For Unusual Pressure.
4.CHECK SETTING OF TEMPERATURE SETTING TRIMMER
Check the setting of temperature setting trimmer. Refer to Temperature Setting Trimmer.
1. Check that the temperature setting trimmer is set to "+ direction".

NOTE:
The control temperature can be set with the setting of temperature setting trimmer.
2. Set temperature control dial to "0".
Are the symptoms solved?
YES - INSPECTION END
NO - GO TO 5.
5.PERFORM SELF-DIAGNOSIS

6.CHECK DRIVE BELT
Check tension of the drive belt. Refer to Checking.
Is the inspection result normal?
YES - GO TO 7.
NO - Adjust or replace drive belt.
7.CHECK AIR LEAKAGE FROM DUCT
Check duct and nozzle, etc. of A/C system for air leakage.
Is the inspection result normal?
YES - GO TO 8.
NO - Repair or replace parts according to the inspection results.
8.CHECK ECV
Perform the ECV diagnosis procedure. Refer to ECV (Electrical Control Valve).
Is the inspection result normal?
