ENG SPEED [rpm]qqIIndicates the engine speed computed
from the REF signal (180É signal) of the
camshaft position sensor.IAccuracy becomes poor if engine
speed drops below the idle rpm.
IIf the signal is interrupted while the
engine is running, an abnormal value
may be indicated.

sensor is displayed.IWhen the engine is stopped, a cer-
tain value is indicated.
COOLAN TEMP/S
[ÉC] or [ÉF]qqIThe engine coolant temperature (deter-
mined by the signal voltage of the
engine coolant temperature sensor) is
displayed.IWhen the engine coolant tempera-
ture sensor is open or short-circuited,
ECM enters fail-safe mode. The
engine coolant temperature deter-
mined by the ECM is displayed.

(front) signal during air-fuel ratio feed-
back control:
RICH ... means the mixture became
ªrichº, and control is being affected
toward a leaner mixture.
LEAN ... means the mixture became
ªleanº, and control is being affected
toward a rich mixture.IAfter turning ON the ignition switch,
ªRICHº is displayed until air-fuel mix-
ture ratio feedback control begins.
IWhen the air-fuel ratio feedback is
clamped, the value just before the
clamping is displayed continuously.
HO2S2 MNTR (B1)
[RICH/LEAN]qIDisplay of heated oxygen sensor 2 (rear)
signal:
RICH ... means the amount of oxygen
after three way catalyst is relatively
small.
LEAN ... means the amount of oxygen
after three way catalyst is relatively
large.IWhen the engine is stopped, a cer-
tain value is indicated.

vehicle speed sensor signal or ABS
actuator and electric unit (control unit)

[ÉC] or [ÉF]qIThe intake air temperature determined
by the signal voltage of the intake air
temperature sensor is indicated.
START SIGNAL
[ON/OFF]qqIIndicates [ON/OFF] condition from the
starter signal.IAfter starting the engine, [OFF] is
displayed regardless of the starter
signal.

System Description
Xenon type headlamp is adopted to the low beam headlamps. Xenon bulbs do not use a filament. Instead,
they produce light when a high voltage current is passed between two tungsten electrodes through a mix-
ture of xenon (an insert gas) and certain other metal hallides. In addition to added lighting power, electronic
control of the power supply gives the headlamps stable quality and tone color.
Following are some of the many advantage of the xenon type headlamp.

The light produced by the headlamps is white color approximating sunlight that is easy on the eyes.

Light output is nearly double that of halogen headlamps, affording increased area of illumination.

The light features a high relative spectral distribution at wavelengths to the human eye is most sensitive,
which means that even in the rain, more light is reflected back from the road surface toward the vehicle,
for added visibility.

Power consumption is approximately 25 percent less than halogen headlamps, reducing battery load.

FUNCTION

The TCU has the following control functions.
Item Details of control
Direction indicatorsSwitches the director indicators (Left, Right or All) when the combination switch or
hazard switch is operated.
Trailer direction indicator buzzer Sounds a buzzer during direction indicator operation when towing a trailer.
Light warning buzzerSounds warning buzzer when driver’s door is opened with light switch in the 1st or
2nd position and ignition switch“OFF”.
Ignition key warning buzzerSounds warning buzzer when driver’s door is opened with key in ignition and the
driver door lock knob is moved from the“unlock”position to the“lock”position.
Rear window defogger timerTurn off rear window defogger and door mirror heater, if equipped, about 15 minutes
after the rear window defogger switch is turned“ON”.
Battery saverShuts off interior lamp in 30 minutes if any door is left open when ignition switch is
“OFF”. The battery saver will reset if ignition switch is cycled or any door is opened
or closed.
Interior lamp timerKeep interior lamp illuminated for about 30 seconds when:

driver’s door is unlocked,

the ignition is switched off,

driver’s door is opened and then closed.
The timer is cancelled, and interior lamp turns off when:

driver’s door is locked, or

ignition switch is turned“ON”.
Theft warning
systemNormal operationMonitors doors, hood, boot lid, door locks, volumetric sensors (if not excluded), igni-
tion and glass break sensors (wagon) when armed.
Flashes the direction indicators and sounds the horn for 30 seconds in case one of
the monitored sensors is triggered.
Diagnostic mode Indicates the last three alarm triggers by flashing the direction indicators.
Central door lock Centrally locks and unlocks the vehicle
Super lock Activates and de-activates the super lock system.

IIf not, turn crankshaft one revolution (360É) and align as
described above.
4. Check only those valves shown in the figure.
IUsing a feeler gauge, measure clearance between valve lifter
and camshaft.
IRecord any valve clearance measurements which are out of
specification. They will be used later to determine the required
replacement adjusting shim.
Valve clearance for checking (Hot):
Intake
0.21 - 0.49 mm (0.008 - 0.019 in)
Exhaust
0.30 - 0.58 mm (0.012 - 0.023 in)
5. Turn crankshaft one revolution (360É) and align mark on crank-
shaft pulley with pointer.
6. Check only those valves shown in the figure.
IUse the same procedure as mentioned in step 4.
7. If all valve clearances are within specification, install the fol-
lowing parts:
IRocker cover
IAll spark plugs
ADJUSTINGNCEM0041S02Adjust valve clearance while engine is cold.
1. Turn crankshaft. Position cam lobe upward on camshaft for
valve that must be adjusted.
2. Place Tool (A) around camshaft as shown in figure.
Before placing Tool (A), rotate notch toward center of cylinder
head. (See figure.) This will simplify shim removal later.
CAUTION:
Be careful not to damage cam surface with Tool (A).

IAlways use new valve oil seal. Refer to EM-29.
IBefore installing valve oil seal, install valve spring seat.
IAfter installing valve components, tap valve stem tip with
a plastic hammer to assure a proper fit.
IInstall valve spring (narrow pitch at both ends of spring)
with either end toward cylinder head.
InstallationNCEM00211. Before installing cylinder head gasket, apply a continuous
bead of liquid gasket to mating surface of cylinder block.

hook will release automatically. Make sure arrow A points
toward engine front.
6. Use a scraper to remove old liquid gasket from mating surface
of front cover.
IAlso remove old liquid gasket from mating surface of cyl-
inder block.
7. Apply a continuous bead of liquid gasket to front cover.
Also apply liquid gasket to matching surface to cylinder head
gasket.
IUse Genuine RTV silicone sealant part No. 999MP-A7007
or equivalent.
Be sure to install new front oil seal in the right direction.
Refer to EM-84, ªFRONT OIL SEALº.

IBefore installing valve oil seal, install valve spring seat.
IInstall valve spring (uneven pitch type) with its narrow
pitched side toward cylinder head side (paint mark).
IAfter installing valve component parts, tap valve stem tip
with plastic hammer to assure a proper fit.
7. Check hydraulic lash adjusters.
a. Push rocker arm at hydraulic lash adjuster location, and see if
rocker arm moves. If it moves at least 1 mm (0.04 in), it indi-
cates that there is air in the high pressure chamber.
Noise will be emitted from hydraulic lash adjuster if engine is
started without bleeding air.
b. Remove hydraulic lash adjuster and dip in a container filled
with engine oil. While pushing plunger as shown in figure,
lightly push check ball using a thin rod. Air is completely bled
when plunger no longer moves.
Air cannot be bled from this type of lash adjuster by running
the engine.
8. Install rocker arms, shims, rocker arm guides and hydraulic
lash adjusters.
CAUTION:
Install all parts in their original positions.
9. Select a suitable shim when replacing any of the following
parts with a new one: Cylinder head, shim, rocker arm guide
and valve seat. Proceed as follows to select the shim of cor-
rect thickness.
a. Install valve component parts to cylinder head (Except shim).
IAlways replace rocker arm guide with a new one.
