  1. REFRIGERANT SHORTAGE CHECK USING GTS 
    1. Prepare the vehicle according to the table below.
      MEASUREMENT CONDITION:

      Item Condition
      Vehicle Condition Ignition switch ON (Engine running)
      A/C Switch On
      Ambient Temperature*1 0 to 49°C (32 to 120°F)
      Air Conditioning Air Inlet Temperature*2 25 to 35°C (77 to 95°F)
      Set Temperature MAX COLD
      Recirculation/fresh Control Switch Recirculation
      Air Vent Damper Position FACE
      Blower Speed HI

      HINT: 

      *1: This inspection can be judged correctly only if the ambient temperature is within a range of 0 to 49°C (32 to 120°F). Therefore, postpone the test if the temperature is low.

      *2: This inspection can be judged correctly only if the air inlet temperature is within a range of 25 to 35°C (77 to 95°F). Therefore, postpone the test if the temperature is out of range.

    2. Using the GTS, check the amount of refrigerant.

      Refrigerant Gas Volume Check
      NOTE:

      If the conditions for the inspection are not met, "Refrigerant incorrect" will be displayed on the GTS. Confirm the conditions of the inspection and perform the check again.

      HINT: 

      • If the amount of refrigerant is insufficient, "Refrigerant shortage" is displayed on the GTS and the indicator light on the A/C switch turns off.
      • When performing this inspection, a DTC will not be output even if "Refrigerant shortage" is displayed on the GTS.
      RESULT:

      Result Amount of Refrigerant Corrective Action
      Refrigerant shortage Insufficient
      1. Check for refrigerant leaks using a gas leak detector, and repair if necessary.
      2. Evacuate the air conditioning system and charge it with the appropriate volume of new or purified refrigerant.

        Refer to REPLACEMENT [12/2019 - ]
      Refrigerant correct Correct -
      Refrigerant incorrect Incorrect Confirm the conditions of the inspection and perform the check again.
