Fast Idle Cam (FIC)
COMPONENT DESCRIPTIONNEEC0502The FIC is installed on the throttle body to maintain adequate
engine speed while the engine is cold. It is operated by a volumet-
ric change in wax located inside the thermo-element. The thermo-
element is operated by engine coolant temperature.

This system automatically controls engine idle speed to a specified
level. Idle speed is controlled through fine adjustment of the
amount of air which bypasses the throttle valve via IACV-AAC
valve. The IACV-AAC valve repeats ON/OFF operation according
to the signal sent from the ECM. The camshaft position sensor
detects the actual engine speed and sends a signal to the ECM.
The ECM then controls the ON/OFF time of the IACV-AAC valve
so that engine speed coincides with the target value memorized in
ECM. The target engine speed is the lowest speed at which the
engine can operate steadily. The optimum value stored in the ECM
is determined by taking into consideration various engine
conditions, such as during warm up, deceleration, and engine load
(air conditioner, power steering and cooling fan operation).
SEF040E
COMPONENT DESCRIPTIONNEEC1594S02The IAC valve-AAC valve is moved by ON/OFF pulses from the
ECM. The longer the ON pulse, the greater the amount of air that
will flow through the valve. The more air that flows through the
valve, the higher the idle speed.

CAUTION:
When a malfunction is indicated, be sure to replace the coolant. Refer to MA section, ªChanging Engine
Coolantº. Also, replace the engine oil.
1) Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure
to use coolant with the proper mixture ratio. Refer to MA section, ªAnti-freeze Coolant Mixture
Ratioº.
2) After refilling coolant, run engine to ensure that no water-flow noise is emitted.

Overall Function CheckNEEC1535WARNING:
Never remove the radiator cap when the engine is hot. Serious
burns could be caused by high pressure fluid escaping from
the radiator.
Wrap a thick cloth around cap. Carefully remove the cap by
turning it a quarter turn to allow built-up pressure to escape.
Then turn the cap all the way off.
1) Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is below
the proper range, skip the following steps and go to ªDiagnos-
tic Procedureº, EC-3345.
2) Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to ªDiagnos-
tic Procedureº, EC-3345.

Bulb Replacement
The headlamp is a semi-sealed beam type which uses a replace-
able halogen bulb. The bulb can be replaced from the engine
compartment side without removing the headlamp body.
+Grasp only the plastic base when handling the bulb.
Never touch the glass envelope.
1. Disconnect the battery cable.
2. Disconnect the harness connector from the back side of the
bulb.
3. Pull off the rubber cap.
4. Push and raise retaining pin to loosen it.
5. Remove the headlamp bulb carefully. Do not shake or rotate
the bulb when removing it.
6. Install in the reverse order of removal.
CAUTION:
Do not leave headlamp reflector without bulb for a long
period of time. Dust, moisture, smoke, etc. entering head-
lamp body may affect the performance of the headlamp.
Remove headlamp bulb from the headlamp reflector just
before a replacement bulb is installed.
Aiming Adjustment
When performing headlamp aiming adjustment, use an aiming
machine, aiming wall screen or headlamp tester. Aimers should
be in good repair, calibrated and operated in accordance with
respective operation manuals.
If any aimer is not available, aiming adjustment can be done as
follows:
For details, refer to the regulations in your own country.
a. Keep all tires inflated to correct pressures.
b. Place vehicle and tester on one and same flat surface.
c. See that there is no-load in vehicle (coolant, engine oil
filled up to correct level and full fuel tank) other than the
driver (or equivalent weight placed in driver's position).
CAUTION:
Be sure aiming switch is set to ª0º when performing aiming
adjustment on vehicles equipped with headlamp aiming
control.

Trouble Diagnosis of Turbocharger
Preliminary check:
+Check that the engine oil level is between MIN and MAX of
the dipstick. (When the engine oil amount is more than MAX,
the oil flows into the inlet duct through the blow-by gas
passage, and the turbocharger is misjudged failure.)
+Ask the customer if he/she always runs the vehicle in idle
engine speed to cool the oil down after driving.
+Replace the turbocharger assembly when any malfunction is
found after unit inspections specified in the table below.
+If no malfunction is found after the unit inspections, judge that
the turbocharger body has no failure. Check the other parts
again.

CAUTION:
+While performing operation, check that all necessary
wires and pipes are disconnected.
+Avoid interference with parts on the vehicle.
Installation
Install the engine in the reverse order of the removal procedure.
+Keep each mount insulator from oil adherence and damage.
+As for a location with positioning pin, insert the pin correctly
to the hole of mating part.
+While keeping each mount insulator free from twisting,
tighten mounting bolts and nuts for the engine mount.
Inspection
+Before starting the engine, check levels of coolant, engine oil,
and other operating fluids, and if necessary, refill them to the
specified level.
+Start the engine, and check that there is no abnormal noise
or vibration.
+Warm up the engine to the sufficient temperature, and check
that there is no leakage of coolant, greases, fuel, or exhaust
gas.
