Remarks: Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

Component Description
INJECTION TIMING CONTROL VALVE
The injection timing control valve is built into the fuel injection
pump. It controls the timer piston to change the fuel injection tim-
ing.
The timing control valve is a solenoid valve located in the line
between high-pressure chamber and low-pressure chamber. It
changes fuel pressure in the high-pressure chamber.
When current flows through the solenoid (the solenoid turns ON),
the timing control valve opens, advancing fuel injection timing.
When current does not flow through it, the timing control valve
closes, retarding injection timing.
The ECM emits an ON-OFF duty signal. The longer the OFF-
duration, the greater the advance angle. The longer the
ON-duration, the greater the retard angle. This means that chang-
ing the ON-OFF duty ratio makes it possible to achieve an optimal
advance angle and accurately control fuel injection timing.

WARNING:
When replacing fuel line parts, be sure to observe the following:
IDisplay a ªCAUTION: INFLAMMABLEº sign in workshop.
I Be sure to furnish workshop with a CO
2fire extinguisher service.
I Do not smoke while servicing fuel system. Keep open flames and sparks away from work area.
I Be sure to disconnect battery ground cable before conducting operations.
I Pour drained fuel into an explosion-proof container, then ensure container lid is installed securely.
CAUTION:
I For ECM models, release fuel pressure from fuel line. Refer to EC section (ªFuel Pressure Releaseº,
ªBASIC SERVICE PROCEDUREº).
I Do not disconnect any fuel line unless absolutely necessary.
I Plug hose and pipe openings to prevent entry of dust or dirt.
I Always replace top lid seal and hose clamps with new ones.
I Do not kink or twist hoses and tubes during installation.
I Do not tighten hose clamps excessively because this could cause damage to the hose.
I Ensure fuel check valve is installed in the correct orientation.
I Refer to EC section (ªFUEL CHECK VALVEº, ªEVAPORATIVE EMISSION SYSTEMº).

5. Bleed the air from the rear brake piping.
6. To adjust the LSV correctly, proceed as follows:
a. With unladen vehicle (12 liters of fuel, radiator coolant andengine oil are full). Spare tire, hand tools and mats in desig-
nated positions. Ensure all doors are closed and no one is
inside of the car. Check the length of LSV spring ªLº.
b. If the spring length is different from that specified, move the regulation lever (2) until the specified value is obtained. Move
the LSV lever (1) until it contacts the stopper bolt and recheck
the spring length.Sensor spring length ªLº Hardtop: 211 mm (8.31 in)
Wagon: 209 mm (8.23 in)
NOTE: Do not disturb stopper bolt.
c. Start the engine and run it at idling speed.
d. Slowly depress the brake pedal until an input pressure of 4,805 kPa (48.1 bar, 49 kg/cm
2, 697 psi) is obtained (at the front axle
pressure gauge) and an output pressure of 1,736 - 2,501 kPa
(18 - 26 bar, 17.7 - 25.5 kg/cm
2, 252 - 363 psi) is obtained (at
the rear axle pressure gauge).
If the output pressure at the rear axle pressure gauge is not within
the specified values, adjust LSV spring length as described under
b) until the output pressure measured is within the specified range.

Bulb Replacement
The headlamp is a semi-sealed beam type which uses a replacable
halogen bulb. The bulb can be replaced from the engine compart-
ment side without removing the headlamp body.
IGrasp 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. Press end of the retaining pin together to release bulb.
5. Remove the headlamp bulb. Do not shake or rotate the bulb when removing it.
6. Install the new bulb in reverse order of removal.
CAUTION:
I Do not leave headlamp reflector without bulb for a long
period of time as dust, moisture, smoke, etc. may enter the
headlamp body and affect the performance of the head-
lamp. Thus, the headlamp bulb should not be removed
from the headlamp reflector until just before a replacement
bulb is to be installed.
Aiming Adjustment
When performing headlamp aiming adjustment, use an aiming
machine, aiming wall screen or headlamp tester. For operating
instructions, of any aimer, it should be in good repair, calibrated and
used according to respective operation manuals supplied with the
unit.
For details, refer to the regulations in your own country.
Before performing aiming adjustment, check the following:
a. Keep all tires inflated to correct pressures.
b. Place vehicle and tester on one and same flat surface.
c. See that there is noload in vehicle other than coolant,
engine oil filled up to correct level, full fuel tank and 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 con-
trol.

Front Fog Lamp Aiming Adjustment
When performing fog lamp aiming adjustment, use an aiming
machine, aiming wall screen or headlamp tester. The aimer should
be in good operational condition, calibrated and used according to
the relevant operation manuals supplied with the unit.
If an aimer is not available, aiming adjustment can be done as fol-
lows:
For details, refer to the regulations in your own country.
CAUTION:
IKeep all tires inflated to correct pressures.
I Place vehicle and tester on one and the same flat surface.
I Ensure that there is no-load in the vehicle other than
coolant, engine oil (filled up to correct level), full fuel tank
and the driver (or equivalent weight placed in driver's posi-
tion).
For details of front fog lamp aiming adjustment, refer to ªAiming
Adjustmentº, EL-47.
Check the distance between the vehicle and the ground illumina-
tion point of the main axis of the fog lamp beam. Keep the distance
to approximately 40 m (131 ft).
