Front Window Fogging [12/2019 - 10/2022]: Procedure
- CHECK REFRIGERANT SHORTAGE
- Prepare the vehicle according to the table below.MEASUREMENT CONDITION:
Item Condition Vehicle Condition 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.
- 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.
