PERFORMANCE TEST
1) Confirm that vehicle and environmental conditions are as fol-
lows.
– Vehicle is not exposed to direct sun.
– Ambient temperature is within 15
C – 35
C (59
F – 95
F)
2) Connect high and low side charging hoses of manifold gauge
to hose fittings of A/C component.
3) Warm up engine to normal operating temperature and keep it
at specified idle speed. (Radiator cooling fan should not be
working when checking pressure and temperature.)
4) Turn A/C switch ON, and set blower switch at “HI”, temperature
lever at “COOL”, fresh/circulation control lever at “CIRCULA-
TION”, (Confirm that A/C compressor and condenser fan are
working.)
5) Keep all windows, doors and engine food open.
6) With about 20 mm (0.8 in) of dry bulb thermometer inserted into
center duct air outlet and another one set near evaporator air
inlet, read temperature indicated on each thermometer.

7) Check for each pressure of low side and high side if it is within
shaded range of left graph.
NOTE:
Pressure registered on gauge varies with ambient temper-
ature. Therefore, use left graphs when determining if pres-
sures are normal or not.
Example:
If each gauge reading is out of specified pressure, correct de-
fective part referring to following Diagnosis table.
