Inspection procedure

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 "INSPECTION " (VQ37VHR) or "INSPECTION " (VK50VE).

NO-2: GO TO 2 after repairing or replacing the parts according to the inspection results.

1. Connect recovery/recycling recharging equipment to the vehicle and discharge the refrigerant. Refer to "COLLECTION AND CHARGE " (VQ37VHR) or "COLLECTION AND CHARGE " (VK50VE).
2. Recharge with the proper amount of refrigerant. Refer to "COLLECTION AND CHARGE " (VQ37VHR) or "COLLECTION AND CHARGE " (VK50VE).
3. Perform the inspection with the refrigerant leakage detecting fluorescent leak detector. Refer to "INSPECTION " (VQ37VHR) or "INSPECTION " (VK50VE).

   Is the inspection result normal? 

   YES: GO TO 3.

   NO: Refill the refrigerant and repair or replace the parts according to the inspection results.

Connect recovery/recycling recharging equipment to the vehicle and perform the performance test. Refer to "PERFORMANCE CHART " (VQ37VHR) or "PERFORMANCE CHART " (VK50VE).

Is the inspection result normal? 

YES: GO TO 4.

NO: Perform the diagnosis with the gauge pressure. Refer to "TROUBLE DIAGNOSIS FOR UNUSUAL PRESSURE " (VQ37VHR) or "TROUBLE DIAGNOSIS FOR UNUSUAL PRESSURE " (VK50VE).

Check the setting of temperature setting trimmer. Refer to "WITHOUT ACCS: TEMPERATURE SETTING TRIMMER " (WITHOUT ACCS) or "WITH ACCS: TEMPERATURE SETTING TRIMMER " (WITH ACCS).

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?
