3. INSPECT IDLE-UP SPEED
(a) Warm up engine
(b) Inspect idle-up speed when following conditions are es-
tablished.
Test conditions:

Fan speed selector at ºHIº position

Temperature control dial at ºCOOLº position

A/C switch ON

Put gear shift in neutral
Magnetic clutch conditionIdle-up speed
Magnetic clutch not engaged700 ± 50 rpm
Magnetic clutch engaged780 ± 50 rpm
If idle speed is not as specified, check the idle control system.
4. INSPECT FOR LEAKAGE OF REFRIGERANT
(a) Stop engine.
(b) Secure good ventilation (The gas leak detector may not
react to volatile gases which are not refrigerant, such as
evaporated gasoline and exhaust gas)
(c) Repeat the test 2 or 3 times
(d) Make sure that there is some refrigerant remaining in the
refrigeration system.
When compressor is OFF: approx. 392 - 588 kPa (4 - 6
kgf´cm
2, 57 - 85 psi)
(e) Bring the gas leak detector close to the drain hose before
performing the test.
HINT:

After the blower motor stops, leave the cooling for more
than 15 minutes.

Expose the gas leak detector sensor 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 gas leaks are detected, lift up the vehicle.
(f) If gas leaks are not detected on the drain hose, remove
the blower resistor from the cooling unit. Then insert the
gas leak detector sensor into the unit to perform the test.
(g) Disconnect the connector and leave the pressure switch
for approx. 20 minutes. Then bring the gas leak detector
close to the pressure switch to perform the test.
(h) Bring the gas leak detector close to the refrigerant lines.

6. FOR VEHICLES EQUIPPED WITH A CATALYTIC CONVERTER
CAUTION:
If large amount of unburned gasoline flows into the converter, it may overheat and create a fire haz-
ard. To prevent this, observe the following precautions and explain them to your customer.
(a) Use only unleaded gasoline.
(b) Avoid prolonged idling.
Avoid running the engine at idle speed for more than 20 minutes.
(c) Avoid spark jump test.
(1) Perform spark jump test only when absolutely necessary. Perform this test as rapidly as possible.
(2) While testing, never race the engine.
(d) Avoid prolonged engine compression measurement.
Engine compression tests must be done as rapidly as possible.
(e) Do not run engine when fuel tank is nearly empty.
This may cause the engine to misfire and create an extra load on the converter.
(f) Avoid coasting with ignition turned off and prolonged braking.
(g) Do not dispose of used catalyst along with parts contaminated with gasoline or oil.
7. IF VEHICLE IS EQUIPPED WITH MOBILE COMMUNICATION SYSTEM
For vehicles with mobile communication systems such as two-way radios and cellular telephones, observe
the following precautions.
(1) Install the antenna as far as possible away from the ECU and sensors of the vehicle's electronic
system.
(2) Install the antenna feeder at least 20 cm (7.87 in.) away from the ECU and sensors of the ve-
hicle's electronic systems. For details about ECU and sensors locations, refer to the section on
the applicable component.
(3) Do not wind the antenna feeder together with the other wiring as much as possible, also avoid
running the antenna feeder parallel with other wire harnesses.
(4) Check that the antenna and feeder are correctly adjusted.
(5) Do not install powerful mobile communications system.
8. FOR USING OBD II SCAN TOOL OR TOYOTA HAND-HELD TESTER
CAUTION:
Observe the following items for safety reasons:
Before using the OBD II scan tool or TOYOTA hand-held tester, the OBD II scan tool's instruc-
tion book or TOYOTA hand-held tester's operator manual should be read thoroughly.
Be sure to route all cables securely when driving with the OBD II scan tool or TOYOTA hand-
held tester connected to the vehicle. (i.e. Keep cables away from feet, pedals, steering wheel
and shift lever.)
Two persons are required when test driving with the OBD II scan tool or TOYOTA hand-held
tester, one person to drive the vehicle and the other person to operate the OBD II scan tool or
TOYOTA hand-held tester.

REPLACEMENT
CAUTION:

Prolonged and repeated contact with mineral oil will
result in the removal of natural fats from the skin,
leading to dryness, irritation and dermatitis. In addi-
tion, used engine oil contains potentially harmful
contaminants which may cause skin cancer.

Care should be taken, therefore, when changing en-
gine oil to minimize the frequency and length of time
your skin is exposed to used engine oil. Protective
clothing and gloves that cannot be penetrated by oil
should be worn. The skin should be thoroughly
washed with soap and water, or use water-less hand
cleaner, to remove any used engine oil. Do not use
gasoline, thinners, or solvents.

In order to preserve the environment, used oil and
used oil filters must be disposed of only at desig-
nated disposal sites.
1. DRAIN ENGINE OIL
(a) Remove the 2 nuts and engine under cover No.3.
(b) Remove the oil filler cap.
(c) Remove the oil drain plug, and drain the oil into a contain-
er.
2. REPLACE OIL FILTER
(a) Remove the 2 bolts and service hole cover.
