CHECK CHART FOR RESISTANCE AND CONTINUITY
BETWEEN TERMINALS
1. Turn the ignition switch to LOCK (OFF) position.
2. Disconnect the engine-ECU connector.
3. Measure the resistance and check for continuity between
the terminals of the engine-ECU harness-side connector
while referring to the check chart.
NOTE
(1) When measuring resistance and checking continuity,
a harness for checking contact pin pressure should
be used instead of inserting a test probe.
(2) Checking need not be carried out in the order given
in the chart.
Caution
If the terminals that should be checked are mistaken,
or if connector terminals are not correctly shorted
to earth, damage may be caused to the vehicle wiring,
sensors, engine-ECU and/or ohmmeter.
Be careful to prevent this!
4. If the ohmmeter shows any deviation from the standard
value, check the corresponding sensor, actuator and
related electrical wiring, and then repair or replace.
5. After repair or replacement, recheck with the ohmmeter
to confirm that the repair or replacement has corrected
the problem.

ENGINE COOLING -General Information/
Service Specifications/Lubricant/Sealant14-2
GENERAL INFORMATION
The cooling system is designed to keep every part
of the engine at appropriate temperature in
whatever condition the engine may be operated.
The cooling method is of the water-cooled, pressure
forced circulation type in which the water pump
pressurizes coolant and circulates it throughout the
engine. If the coolant temperature exceeds the
prescribed temperature, the thermostat opens to
circulate the coolant through the radiator as well
so that the heat absorbed by the coolant may be
radiated into the air.The water pump is of the centrifugal type and is
driven by the drive belt from the crankshaft.
The radiator is the corrugated fin, down flow type.

INTAKE AND EXHAUST -General Information/Service Specifications/Sealant15-3
At starting and driving at low speed, the duty control
value of the variable geometry solenoid valve is
increased to apply the vacuum pressure of the
vacuum pump to the variable geometry actuator.
Applying the vacuum pressure to the variable
geometry actuator pulls the actuator rod so that
it can move towards the direction of closing the
variable nozzle of the variable geometry
turbocharger. As closing the nozzle reduces the
exhaust gas mass, the speed of exhaust gas flow
will be increased and efficiency will be improved.
Since the characteristic of boost pressure becomes
a low speed type, boost pressure will suddenly
rise from low speed.
At driving at high speed, the duty control value
of the variable geometry solenoid valve is
decreased to reduce the vacuum pressure from
the vacuum pump so that the actuator rod can
return to the deactivated status and move towards
the direction of opening the nozzle of the variable
geometry turbocharger.Opening the nozzle allows the characteristic of
boost pressure to become a high speed type so
that the appropriate boost pressure can be
maintained.
Therefore, boost pressure can be controlled by
appropriate duty control of the variable geometry
solenoid valve. The engine-ECU calculates the
correct boost pressure based on the engine speed
and fuel injection amount. Furthermore, the duty
control of the variable geometry solenoid valve is
given feedback of the signals from the variable
geometry control pressure sensor and the boost
pressure sensor so that the variable nozzle opening
angle of the variable geometry turbocharger can
be quickly adjusted to obtain the desired boost
pressure.
