3. 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 yo\
ur 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 con\
verter.
(f) Avoid coasting with ignition turned off.
(g) Do not dispose of used catalyst along with parts contaminated with gasol\
ine or oil.
4. 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 se\
nsors of the ve- hicle’s electronic systems. For details about ECU and sensors locations, refer\
to the section on
the applicable component.
(3) Avoid winding the antenna feeder together with other wiring as much as possible, and 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.
5. 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 too\
l 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.

COOLING RADIATOR
1996 LAND CRUISER (RM451U)
ON−VEHICLE INSPECTION
1. REMOVE RADIATOR TANK CAP
CAUTION:
To avoid the danger of being burned, do not remove the ra-
diator cap while the engine and radiator are still hot, as fluid
and steam can be blown out under pressure.
2. INSPECT RADIATOR CAP
NOTICE:
If the radiator cap has contaminations, always rinse it with
water. Before using a radiator cap tester, wet the relief
valve and pressure valve with coolant or water.
Using a radiator cap tester, pump the tester and measure the
relief valve opening pressure. Standard opening pressure:
74 − 103 kPa
(0.75 − 1.05 kgf/cm
2, 10.7 − 14.9 psi)
Minimum opening pressure:
59 kPa (0.6 kgf/cm
2, 8.5 psi)
HINT:
Use the tester’s maximum reading as the opening pressure.
If the opening pressure is less than minimum, replace the radia-
tor cap.
3. INSPECT COOLING SYSTEM FOR LEAKS
(a) Fill the radiator with coolant and attach a radiator cap tes-
ter.
(b) Warm up the engine.
(c) Pump it to 118 kPa (1.2 kgf/cm
2, 17.1 psi), and check that
the pressure does not drop.
If the pressure drops, check the hoses, radiator or water pump
for leaks. If no external leaks are found, check the heater core,
cylinder block and head.
4. REINSTALL RADIATOR CAP

Fuel Pressure Control Circuit
CIRCUIT DESCRIPTION
The ECM turns on a VSV (V acuum Switching Valve) to draw the
air into the diaphragm chamber of the pressure regulator if it de-
tects that the temperature of the engine coolant is too high dur-
ing engine starting.
The air drawn into the chamber increases the fuel pressure to
prevent fuel vapor lock at high engine temperature in order to
help the engine start when it is warm.
Fuel pressure control ends approx. 120 sec. after the engine is
started.

EMISSION CONTROL SYSTEM
PURPOSE
The emission control systems are installed to reduce the amount of HC, CO a\
nd NOx exhausted from the
engine ((3), (4) and (5)), to prevent the atmospheric release of blow −by gas− containing HC (1) and evapo-
rated fuel containing HC being released from the fuel tank (2).
The function of each system is shown in the following table.
SystemAbbreviationFunction
(1) Positive Crankcase V entilation
(2) Evaporative Emission Control
(3) Exhaust Gas Recirculation
(4) Three− Way Catalytic Converter
(5) Sequential Multiport Fuel Injection*PCV

EMISSION CONTROL EVAPORATIVE EMISSION (EVAP) CONTROL SYSTEM
1996 LAND CRUISER (RM451U)
INSPECTION
1. VISUALLY INSPECT LINES AND CONNECTIONS
Look for loose connections, sharp bends or damage.
2. VISUALLY INSPECT FUEL TANK
Look for deformation, cracks or fuel leakage.
3. VISUALLY INSPECT FUEL TANK CAP
Check if the cap and/or gasket are deformed or damaged.
If necessary, repair or replace the cap.
4. INSPECT TVV OPERATION WITH COLD ENGINE
(a) The engine coolant temperature should be below 45 °C
(113 °F).
(b) Disconnect the EVAP hose from the union pipe.
(c) Start the engine.
(d) Gradually increase the engine speed from idle to 3,000 rpm and check that air suction is not felt at the union pipe.
5. INSPECT OPERATION OF VCV WITH HOT ENGINE
(a) Warm up the engine.
(b) With the engine idling, check that air suction is not felt at union pipe.
(c) Gradually increase the engine speed to 3,000 rpm and check that there is air suction at the union pipe.
(d) Reconnect the EVAP hose to the union pipe.
If no problem is found with this inspection, system is normal;
otherwise inspect each part.
