a.

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.



b.

Using the GTS, check the amount of refrigerant.
