CIRCUIT DESCRIPTION
The speed sensor detects wheel speed and sends the ap-
propriate signals to the ECU. These signals are used to control
the ABS system. The front and rear rotors each have 48 serra-
tions.
When the rotors rotate, the magnetic field emitted by the perma-
nent magnet in the speed sensor generates an AC voltage.
Since the frequency of this AC voltage changes in direct propor-
tion to the speed of the rotor, the frequency is used by the ECU
to detect the speed of each wheel.

tinues for 15 sec. or more.
2. Momentary interruption of the speed sensor signal oc-
curs 7 times or more.
3. Vehicle speed is at 20 km/h (12mph) or more and inter-
ference on the speed sensor signal continues for 5 sec.
or more.
4. Open circuit condition of the speed sensor signal circuit
continues for 0.5 sec. or more.

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.

19. INSTALL RH AND LH TIE ROD ENDS AND LOCK NUTS
(a) Screw the lock nut and tie rod end onto the rack end until
the matchmarks are aligned.
(b) After adjusting toe±in, torque the nut.
(See page SA±4)
Torque: 74 N´m (750 kgf´cm, 54 ft´lbf)
20. INSTALL 2 TURN PRESSURE TUBES
(a) Coat 2 new O±rings with power steering fluid and install
them to the tube.
(b) Using SST, install the tube.

NOTICE:
After the camber has been adjusted, inspect the toe±in.
(a) Remove the front wheels and speed sensor clamp.
(b) Remove the 2 nuts on the lower side of the shock absorb-
er.
(c) Coat the threads of the nuts with engine oil.
(d) Temporarily install the 2 nuts.
(e) Adjust the camber by pushing or pulling the lower side of
the shock absorber in the direction in which the camber
adjustment is required.
(f) Tighten the nuts.
Torque: 211 N´m (2,150 kgf´cm, 156 ft´lbf)
(g) Install the front wheels.
Torque: 103 N´m (1,050 kgf´cm, 76 ft´lbf)
(h) Check the camber.
HINT:

Try to adjust the camber to the center value.

Adjusting value for the set bolts is 6' ± 30' (0.1° ± 0.5°).
If the camber is not within the specification, using the table be-
low, estimate for how much additional camber adjustment will
be required, and select the camber adjusting bolt.
(i) Follow the above mentioned steps again. Between step
(b) and (c), exchange 1 or 2 selected bolts.
HINT:
When exchanging the 2 bolts, exchange 1 bolt for each time.

BRAKE VIBRATION AND/OR PULSATIONPage 2 of 6
B. PEDAL PULSATION
Applying brakes causes the brake pedal to pulsate. This brake pulsation sometimes
causes the steering wheel to oscillate when the brakes are applied (See Figure 2 below).
2) CAUSE OF VIBRATION/PULSATION PROBLEMS
Brake rotor thickness variation causes brake vibration due to changes in the braking force as
thick/thin portions of the rotor pass the pads. Brake rotor thickness variation can be measured
with a micrometer as shown in Figure 3 below.
