5) Warm up engine to the normal operating temperature and keep it at the specified idle speed.
6) Turn A/C switch ON, set blower speed selector at maximum speed position, temperature selector at
maximum cold position, airflow selector at face
position, and air intake switch at recirculation
position. (Confirm that A/C compressor and
condenser fans are working.)
7) Wait for ten minutes to stabilize the A/C operation.
8) Open front windows, front doors and engine hood.
9) With about 20 mm (0.8 in.) of dry bulb thermometer
(1) put right in front of center ventilation louver and a
wet and dry bulb thermometer (2) near air inlet of
HVAC unit. 10) Check for each pressure of low side and high side if
it is within shaded range of graph. If each gauge
reading is out of specified pressure, correct defective
part referring to the following table.
NOTE
Pressure registered on gauge varies with
ambient temperature. Therefore, use the
graphs when determining if pressures are
normal or not.
Low side and high side pressure example,
Gauges should read as follows when ambient
temperature is 30 °C (86 °F)
Pressure on high pressure gauge (HI): 1590 –
1940 kPa (15.9 – 19.4 kg/cm2)
Pressure on low pressure gauge (LO): 270 – 430

Magnet Clutch InspectionS7RS0B7216022
• Check armature plate and magnet clutch pulley for wear and oil soak respectively.
• Check magnet clutch pulley bearing for noise, wear and grease leakage.
• Measure magnet clutch coil for resistance at 20 °C (68
° F). If the measured resistance does out of
specification, replace magnet clutch assembly.
Magnet clutch coil resistance
Standard: 3.5 – 4.0 Ω

8) Adjust clearance between magnet clutch plate (1) and magnet clutch pulley by putting shim(s) on
compressor shaft. To measure the clearance,
perform the following steps.
a) Put compressor in a vise (2).
b) Set dial gauge (3) on magnet clutch plate, and then adjust its pointer at 0.
c) Connect battery positive terminal (+) to magnet clutch coil lead wire.
d) Connect battery negative terminal (–) to compressor body assemb ly. (At this point,
magnet clutch plate and magnet clutch pulley are
kept in contact.) e) Disconnect battery negative terminal (–) to
compressor body assembly. (At this point,
magnet clutch plate and magnet clutch pulley are
not in contact.)
f) Read stroke of magnet clutch plate from dial gauge by performing step d) and e) repeatedly.
(Stroke of magnet clutch plate is clearance
between magnet clutch plate and magnet clutch
pulley.)
Standard clearance between magnet clutch plate
and magnet clutch plate
0.3 – 0.5 mm (0.012 – 0.020 in.)
