Front Window Fogging [11/2023 - ]: Procedure

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

      Item Condition
      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.

      Tester Display
      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
      Refrigerant shortage Insufficient or leakage
      Refrigerant correct Correct
      Refrigerant incorrect Incorrect

      OK

      "Refrigerant correct" is displayed on the GTS.

    See step  2

  2. CHECK OPERATION 
    1. Check that the air conditioning system changes to DEF mode according to the switch operation, when the MODE switch on the air conditioning control assembly is pushed.

      OK

      Air conditioning system changes to DEF mode.
