Check that the following conditions are met and perform the refrigerant shortage check according to the display on the GTS.

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

NOTICE:

When the GTS is operated without the check conditions satisfied, "Refrigerant incorrect" is displayed. Select "Yes" to return to the previous screen.

HINT:

·

Refer to the GTS operator's manual for further details.

·

A message indicating a refrigerant shortage is displayed on the GTS and the air conditioning system turns off if the amount of refrigerant in the system is insufficient.

·

DTCs are not stored when performing the refrigerant shortage check using the GTS.

·

*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.

Result:

Result	Amount of Refrigerant	Corrective Action
Refrigerant shortage	Insufficient	1. Check for refrigerant leaks using a halogen leak detector, and repair if necessary. 2. Evacuate the air conditioning system and charge it with the appropriate volume of new or purified refrigerant. (201910,999999,_58,_083104,_0403061,RM100000001JNG0,)
