GENERAL MAINTENANCE
These are maintenance and inspection items which are considered to be the owner's responsibility.
They can be done by the owner or they can have them done at a service shop.
These items include those which should be checked on a daily basis, those which, in most cases, do not
require (special) tools and those which are considered to be reasonable for the owner to do.
Items and procedures for general maintenance are as follows.
1. GENERAL NOTES

Maintenance items may vary from country to country. Check the owner's manual supplement in which
the maintenance schedule is shown.

Every service item in the periodic maintenance schedule must be performed.

Periodic maintenance service must be performed according to whichever interval in the periodic main-
tenance schedule occurs first, the odometer reading (miles) or the time interval (months).

Maintenance service after the last period should be performed at the same interval as before unless
otherwise noted.

Failure to do even one item an cause the engine to run poorly and increase exhaust emissions.
2. LIGHTS
(a) Check that the headlights, stop lights, taillights, turn signal lights, and other lights are all working.
(b) Check the headlight aim.
3. WARNING LIGHTS AND BUZZERS
Check that all warning lights and buzzers function properly.
4. HORN
Check that it is working.
5. WINDSHIELD GLASS
Check for scratches, pits or abrasions.
6. WINDSHIELD WIPER AND WASHER
(a) Check operation of the wipers and washer.
(b) Check that the wipers do not streak.
7. WINDSHIELD DEFROSTER
Check that air comes out from the defroster outlet when operating the heater or air conditioner.
8. REAR VIEW MIRROR
Check that it is mounted securely.
9. SUN VISORS
Check that they move freely and are mounted securely.
10. STEERING WHEEL
Check that it has the specified freeplay. Be alert for changes in steering condition, such as hard steering,
excessive freeplay or strange noises.
11. SEATS
(a) Check that the seat adjusters operate smoothly.
(b) Check that all latches lock securely in any position.
(c) Check that the head restraints move up and down smoothly and that the locks hold securely in any
latch position.
(d) For fold-down seat backs, check that the latches lock securely.
12. SEAT BELTS
(a) Check that the seat belt system such as the buckles, retractors and anchors operate properly and
smoothly.
(b) Check that the belt webbing is not cut, frayed, worn or damaged.

(b) When installing the battery, be especially careful not to in-
correctly connect the positive (+) and negative (-) cables.
(c) Do not permit parts to receive a severe impact during re-
moval or installation. Handle all SFI parts carefully, espe-
cially the ECM.
(d) Do not be careless during troubleshooting as there are
numerous transistor circuits and even slight terminal con-
tact can further troubles.
(e) Do not open the ECM cover.
(f) When inspecting during rainy weather, take care to pre-
vent entry of water. Also, when washing the engine
compartment, prevent water from getting on the SFI parts
and wiring connectors.
(g) Parts should be replaced as an assembly.
(h) Care is required when pulling out and inserting wiring con-
nectors.
(1) Release the lock and pull out the connector, pulling
on the connectors.
(2) Fully insert the connector and check that it is locked.
(i) When inspecting a connector with a volt/ohmmeter
(1) Carefully take out the water-proofing rubber if it is
a water-proof type connector.
(2) Insert the test probe into the connector from the wir-
ing side when checking the continuity, amperage or
voltage.
(3) Do not apply unnecessary force to the terminal.
(4) After checking, install the water-proofing rubber on
the connector securely.
(j) Use SST for inspection or test of the injector or its wiring
connector.

8. FUEL SYSTEM
(a) When disconnecting the high pressure fuel line, a large
amount of gasoline will spill out, so observe the following
procedures:
(1) Disconnect the fuel pump connector.
(2) Start the engine. After the engine has stopped on
its own, turn off the ignition switch.

6. REMOVE ENGINE UNDER COVER
7. VISUALLY CHECK GENERATOR WIRING AND
LISTEN FOR ABNORMAL NOISES
(a) Check that the wiring is in good condition.
(b) Check that there is no abnormal noise from the generator
while the engine is running.
8. CHECK CHARGE WARNING LIGHT CIRCUIT
(a) Warm up the engine and then turn it off.
(b) Turn off all accessories.
(c) Turn the ignition switch ºONº. Check that the charge warn-
ing light is lit.
(d) Start the engine. Check that the light goes off.
If the light does not go off as specified, troubleshoot the charge
light circuit.
9. INSPECT CHARGING CIRCUIT WITHOUT LOAD
HINT:
If a battery/generator tester is available, connect the tester to
the charging circuit as per manufacturer's instructions.
(a) If a tester is not available, connect a voltmeter and amme-
ter to the charging circuit as follows:

Disconnect the wire from terminal B of the genera-
tor, and connect it to the negative (-) probe of the
ammeter.

Connect the positive (+) probe of the ammeter to
terminal B of the generator.

Connect the positive (+) probe of the voltmeter to
terminal B of the generator.

Ground the negative (-) probe of the voltmeter.
(b) Check the charging circuit as follows:
With the engine running from idling to 2,000 rpm, check
the reading on the ammeter and voltmeter.
Standard amperage: 10 A or less
Standard voltage: 13.2 - 14.8 V
If the voltmeter reading is more than standard voltage, replace
the voltage regulator.
If the voltmeter reading is less than standard voltage, check the
voltage regulator and generator as follows:

With terminal F grounded, start the engine and
check the voltmeter reading of terminal B.

If the voltmeter reading is more than standard volt-
age, replace the voltage regulator.

If the voltmeter reading is less than standard volt-
age, check the generator.

10. INSPECT CHARGING CIRCUIT WITH LOAD
(a) With the engine running at 2,000 rpm, turn on the high
beam headlights and place the heater blower switch at
ºHIº.
(b) Check the reading on the ammeter.
Standard amperage: 30 A or more
If the ammeter reading is less than the standard amperage, re-
pair the generator.
HINT:
If the battery is fully charged the indication will sometimes be
less than standard amperage.

STEERING WHEEL
INSPECTION
1. CHECK STEERING WHEEL FREEPLAY
With the vehicle stopped and tires pointed straight ahead, rock
the steering wheel gently back and forth with light finger pres-
sure.
Freeplay should not exceed the maximum.
Maximum freeplay: 30 mm (1.18 in.)
2. CHECK STEERING EFFORT
(a) Center the steering wheel.
(b) Remove the steering wheel pad.
(See page SR-1 1)
(c) Start the engine and run it at idle.
(d) Measure the steering effort in both directions.
Reference (Maximum): 6.9 N´m (70 kgf´cm, 61 in.´lbf)
If steering effort is excessive, repair the power steering unit.
HINT:
Be sure to consider the tire type, pressure and contact surface
before making your diagnosis.
(e) Disconnect the PPS solenoid connector.
(f) Measure the steering effort in both directions and check
that the steering effort exceeds the reference value in (d),
and that the power assist is operating.
If steering effort is not heavier than (d), check the solenoid.
(g) Connect the connector.
(h) Torque the steering wheel set nut.
Torque: 35 N´m (360 kgf´cm, 26 ft´lbf)
(i) Install the steering wheel pad.
