Front Wheel Alignment

Before checking frontwheel alignment, besure tomake apre-
liminary inspection (Unladen*).
*: Fuel, radiator coolantandengine oilfull. Spare tire,jack,
hand tools andmats indesignated positions.

SFA575B PRELIMINARY INSPECTION

1. Check tiresforwear andimproper inflation.
2. Check wheelrunout.

Wheel runout:
Refer toSOS (FA-30).

3. Check frontwheel bearings forlooseness.
4. Check frontsuspension forlooseness.
5. Check steering linkageforlooseness.
6. Check thatstruts workproperly.
7. Check vehicle posture (Unladen).

TOE-IN Measure toe-inusingfollowing procedure.
WARNING:
• Perform following procedure alwaysonaflat surface.
• Make surethatnoperson isin front ofthe vehicle before
pushing it.

1. Bounce frontofvehicle upand down tostabilize theposture.
2. Push thevehicle straight aheadabout5m (16 ft).
3. Put amark onbase lineoftread (rearside) ofboth tires at
the same height ashub center. Thesearemeasuring points.
4. Measure distance"A"(rear side).
5. Push thevehicle slowlyaheadtorotate thewheels 180
degrees (1/2turn).

If the wheels haverotated morethan180degrees
(112
turn), try
the above procedure againfromthebeginning. Neverpush
vehicle backward.

6. Measure distance"B"(front side).

Total toe-in
Refer toSOS (FA-29).
CAMBER,
CASTERANDKINGPIN INCLINATION
Camber, casterandkingpin inclination arepreset atfactory and
cannot beadjusted.

1. Measure camber,casterandkingpin inclination ofboth right
and leftwheels withasuitable alignment gauge.

Camber, CasterandKingpin inclination:
Refer toSOS (FA-29).

2. Ifcamber, casterorkingpin inclination isnot within
specification, inspectfrontsuspension parts.Replace dam-
aged orworn outparts.

BASIC MULTIPORT FUELINJECTION
SYSTEM

The amount offuel injected fromthefuel injector
is determined bythe ECM. TheECM controls the
length oftime thevalve remains open(injection
pulse duration). Theamount offuel injected isa
program valueinthe ECM memory. Theprogram
value ispreset byengine operating conditions.
These conditions aredetermined byinput signals
(for engine speedandintake air)from boththe
camshaft positionsensorandthemass airflow
sensor.

PRELIMINARY INSPECTION

Make following checks.Adjust,repairorreplace ifnecessary.
• Check tiresforwear andforimproper inflation.
• Check rearwheel bearings forexcessive play.
• Check wheelrunout.

Wheel runout: RefertoSOS inFA section.

• Check thatrear shock absorber worksproperly.
• Check rearaxleandrear suspension partsforexcessive

play.
• Check vehicle posture (Unladen*).
*: Fuel, radiator andengine oilfull. Spare tire,jack, hand
tools andmats indesignated positions.

CAMBER
Camber ispreset atfactory andcannot beadjusted.
Camber: Refer toSOS (RA-12).

• Ifthe camber isnot within specification, inspectandreplace
any damaged orworn rearsuspension parts.

TOE-IN
Toe-in ispreset atfactory andcannot beadjusted.
Measure toe-inusingfollowing procedure. Ifout of
specification, inspectandreplace anydamaged orworn rear
suspension parts.
WARNING:
• Perform following procedure alwaysonaflat surface.
• Make surethatnoperson isin front ofthe vehicle before
pushing it.

1. Bounce rearofvehicle upand down tostabilize theposture.
2. Push thevehicle straight aheadabout5m (16
ft).

3. Putamark onbase lineofthe tread (rearside) ofboth tires at
the same height ofhub center. Thismark isameasuring point.
4. Measure distance"A"(rear side).
5. Push thevehicle slowlyaheadtorotate thewheels 180
degrees (1/2turn).

If the wheels haverotated morethan180degrees (1/2turn), try
the above procedure againfromthebeginning. Neverpush
