Maintenance and Minor Adjustments
Wheel and Tire
Wheel repairs that use welding, heating, or peening are not approved. All damaged wheels should be replaced.
Studs
If a broken stud is found, see Section 3E (rear) or Section 3D (front) for Note and Replacement procedure.
Matched tires and wheels
(For vehicle equipped with steel wheels)
Tires and wheels are matchmounted at the assembly plant.
This means that the radially stiffest part of the tire, or “high spot”,
is matched to the smallest radius or “low spot” of the wheel.
This is done to provide the smoothest possible ride.
The “high spot” of the tire is originally marked by paint dot (1) on
the outboard sidewall. This paint dot will eventually wash off the
tire.
The “low spot” of the wheel is originally marked by paint dot (2) on
the wheel rim-flange. Properly assembled, the wheel rim’s paint
dot should be aligned with the tire’s paint dot as shown in left fig-
ure.
Whenever a tire is dismounted from its wheel, it should be
remounted so that the tire and wheel are matched. If the tire’s
paint dot cannot be located, a line should be scribed on the tire
and wheel before dismounting to assure that it is remounted in
the same position.
Inflation of Tires
The pressure recommended for any model is carefully calculated to give a satisfactory ride, stability, steering,
tread wear, tire life and resistance to bruises.
Tire pressure, with tires cold, (after vehicle has set for three hours or more, or driven less than one mile) should
be checked monthly or before any extended trip. Set to the specifications on the tire placard located on the
driver’s side door lock pillar.
It is normal for tire pressure increase when the tires become hot during driving. Do not bleed or reduce tire pres-
sure after driving. Bleeding reduces the “Cold Inflation Pressure.”
Higher than Recommended Pressure Can Cause:
1) Hard ride
2) Tire bruising or carcass damage
3) Rapid tread wear at center of tire
Unequal Pressure on Same Axle Can Cause:
1) Uneven braking
2) Steering lead
3) Reduced handling
4) Swerve on acceleration
Valve caps should be kept on valves to keep dust and water out.

Fluid Pressure Test (If Equipped with LSPV)
Test procedure for LSPV assembly is as follows.
Before testing, confirm the following.
Fuel tank is filled with fuel fully.
Vehicle is equipped with spare tire, tools, jack and jack han-
dle.
1) Stop vehicle on level floor and place approximately about
140 kg (309 Ibs) weight on rear housing so that rear axle
weights 600 kg (1323 Ib).
Rear axle weight
“L” : 600 kg (1323 lb)
2) Install special tool to front and rear brake.
Special tool
Front brake
(A) : 09956-02310
(B) : 55473-82030 (Use the air bleeder plug supplied as a
spare part)
Rear brake
(A) : 09956-02310
(B) : 55473-82030 (Use the air bleeder plug supplied as a
spare part)
3) Depress brake pedal gradually till fluid pressure of front
brake becomes as specified below and check corresponding
pressure of rear brake. It should be within specification given
below.
As done above, apply 100 kg/cm
2 pressure to front brake and
check that rear brake pressure is within specification as given
below.NOTE:
Special tool should be connected to bleeder plug hole of
front (driver’s side brake) and rear brakes.

INSPECTION
Step Action Yes No
1 1) Disconnect the applicable sensor connector with ignition
switch OFF.
2) Measure resistance between sensor terminals.
Resistance of wheel speed sensor: 1.4 – 1.8 kΩ (at
20°C, 68°F)
3) Measure resistance between each terminal and body
ground.
Insulation resistance: 1MΩ or higher
Were measured resistance values in step 2) and 3) as spec-
ified? (See [A])Go to step 2. Replace sensor.
2 1) Ignition switch OFF.
2) Disconnect connector from ABS hydraulic unit / control
module assembly. (See [B])
3) Check for proper connection to ABS hydraulic unit / con-
trol module assembly at each sensor terminal.
4) If OK, then turn ignition switch ON and measure voltage
between sensor positive terminal of module connector
and body ground.
Is it 0V?Go to step 3. Sensor positive cir-
cuit shorted to
power.
3 1) Ignition switch OFF.
2) Connect connector to sensor.
3) Measure resistance between sensor terminals at mod-
ule connector.
4) Measure resistance between sensor positive terminal
and negative terminal of module connector, between
positive terminal and body ground.
Are measured resistance values within each specified range
described in above step 1?Go to step 4. Circuit open or
shorted to ground.
4 1) Remove wheel speed sensor.
2) Check sensor for damage or foreign material being
attached.
Is it in good condition? (See [C])Go to step 5. Clean or replace
sensor.
5 Check visually through wheel speed sensor installation hole
for following.
Ring serration (teeth) neither missing or damaged.
No foreign material being attached.
Ring not being eccentric.
Wheel bearing free from excessive play.
Are they in good condition? (See [D])Go to step 6. Clean, repair or
replace.
6 1) Install sensor to knuckle or axle housing.
2) Tighten sensor bolt to specified torque and check that
there is not any clearance between sensor and knuckle
or axle housing. (See [E])
Replace sensor if any.
Referring to “Front Wheel Speed Sensor” in this section,
check output voltage or waveform of sensor. Is proper out-
put voltage or waveform obtained?Substitute a known-
good ABS hydraulic
unit / control module
assembly and
recheck.Replace sensor and
recheck.
