3. INSPECT IDLE−UP SPEED
(a) Warm up engine
(b) Inspect idle −up speed when the these conditions are es-
tablished:
Blower switch HI
Electrical load OFF
A/C switch ON
Put gear shift in neutral
Magnetic clutch conditionIdle speed
Magnetic clutch not engaged650 ± 50 rpm
Magnetic clutch engaged800 ± 50 rpm
If idle speed is not as specified, check the IAC valve and air in-
take system.
4. INSPECT FOR LEAKAGE OF REFRIGERANT
(a) Perform in these conditions:
Stop engine.
Secure good ventilation (If not, the gas leak detec-
tor may react to volatile gases which are not refrig-
erant, such as evaporated gasoline and exhaust
gas.)
Repeat the test 2 or 3 times.
Make sure that there is some refrigerant remaining
in the refrigeration system.
When compressor is OFF: approximately 392 − 588
KPa (4 − 6 kgf/cm
2, 57 − 35 psi)
(b) Bring the gas leak detector close to the drain hose before
performing the test.
HINT:
After the blower motor is stopped, leave the cooling unit
for more than 15 minutes.
Expose the gas leak detector sensor the under the drain
hose.
When bring the gas leak detector close to the drain hose,
make sure that the gas leak detector does not react to the
volatile gases.
If such reaction is unavoidable, the vehicle must be lifted up.
(c) If gas leak is not detected on the drain hose, remove the
power transistor from the cooling unit. Then insert the gas
leak detector sensor into the unit and perform the test.
(d) Disconnect the connector and leave the pressure switch for approximately 20 minutes. Then bring the gas leak de-
tector close to the pressure switch and perform the test.
(e) Bring the gas leak detector close to the refrigerant lines and perform the test.
