3F-2 WHEELS AND TIRES
The metric term for tire inflation pressure is the kilopascal (kPa).
Tire pressures will usually be printed in both kPa and psi on the Tire
Placard. Metric tire gauges are available from tool suppliers. The
chart, left table, converts commonly used inflation pressures from
kPa to psi.kPakgf / cm2psi

WHEELS REPLACEMENT
Wheels must be replaced if they are bent, dented, have excessive
lateral or radial runout, leak air through welds, have elongated bolt
holes, if lug nuts won't stay tight, or if they are heavily rusted.
Wheels with greater runout than shown in left figure may cause ob-
jectional vibrations.
Wheels for replacement must be equivalent to the originally
equipped wheels in load capacity, diameter, rim width, off-set and
mounting configuration. A wheel of improper size or type may affect
wheel and bearing life, brake cooling, speedometer / odometer cal-
ibration, ground clearance to the body and chassis.
To measure the wheel runout, it is necessary to use accurate dial
indicator. The tire may be on or off the wheel. The wheel should be
installed to the wheel balancer of the like for proper measurement.
Take measurements of both lateral runout and radial runout at both
inside and outside of the rim flange. With dial indicator set in place
securely, turn the wheel one full revolution slowly and record every
reading of the indicator.
When the measured runout exceeds the specification and correc-
tion by the balancer adjustment is impossible, replace the wheel.
If the reading is affected by welding, paint or scratch, it should be
ignored.
Lateral runout limit ªaº: 1.20 mm (0.047 in.)
Radial runout limit ªbº: 1.20 mm (0.047 in.)
METRIC LUG NUTS AND WHEEL STUDS
All models use metric lug nuts and wheel studs (size M12 x 1.25).

PROPELLER SHAFT JOINT CHECK
If universal joints are suspected of producing chattering or rattling
noise, inspect them for wear. Check to see if cross spider rattles in
yokes or if splines are worn down and replace defective propeller
shaft with new one.
Noise coming from universal joint can be easily distinguished from
other noises because rhythm of chattering or rattling is in step with
cruising speed. Noise is pronounced particularly on standing start
or in coasting condition (when braking effect of engine is showing
in the drive line).

BRAKES 5-3
SUBSTANDARD OR
CONTAMINATED BRAKE FLUID
Improper brake fluid, mineral oil or water in the fluid
may cause the brake fluid to boil or the rubber compo-
nents in the hydraulic system to deteriorate.
If primary piston cups are swollen, then rubber parts
have deteriorated. This deterioration may also be evi-
denced by swollen wheel cylinder piston cups on the
drum brake wheels.
If deterioration of rubber is evident, disassemble all
hydraulic parts and wash with alcohol. Dry these parts
with compressed air before assembly to keep alcohol
out of the system. Replace all rubber parts in the sys-
tem, including hoses. Also, when working on the
brake mechanisms, check for fluid on the linings. If ex-
cessive fluid is found, replace the linings.
If master cylinder piston seals are satisfactory, check
for leakage or excessive heat conditions. If condition
is not found, drain fluid, flush with brake fluid, refill and
bleed system.
The system must be flushed if there is any doubt as
to the grade of fluid in the system or if fluid has been
used which contained parts that have been subjected
to contaminated fluid.
DIAGNOSIS
ROAD TESTING BRAKES
Brakes should be tested on dry, clean, smooth and
reasonably level roadway which is not crowned. Road
test brakes by making brake applications with both
light and heavy pedal forces at various speeds to de-
termine if the vehicle stops evenly and effectively.
Also drive vehicle to see if it leads to one side or the
other without brake application. If it does, check the
tire pressure, front end alignment and front suspen-
sion attachments for looseness. See diagnosis chart
for other causes.
BRAKE FLUID LEAKS
Check the master cylinder fluid levels. While a slight
drop in reservoir level does result from normal lining
wear, an abnormally low level indicates a leak in the
system. In such a case, check the entire brake system
for leakage. If even a slight evidence of leakage is
noted, the cause should be corrected or defective
parts should be replaced.
If fluid level is lower than the minimum level of reser-
voir, refilling is necessary. Fill reservoir with specified
brake fluid.
Brake fluid: Refer to reservoir tank cap.
CAUTION:
Since brake system of this vehicle is factory-
filled with brake fluid indicated on reservoir
tank cap, do not use or mix different type of
fluid when refilling; otherwise serious damage
will occur.
Do not use old or used brake fluid, or any fluid
from a unsealed container.

5E1-2 ANTILOCK BRAKE SYSTEM (ABS) (OPTIONAL)
GENERAL DESCRIPTION
The ABS (Antilock Brake System) controls the fluid pressure applied to the wheel cylinder of each brake from the
master cylinder so that each wheel is not locked even when hard braking is applied. This ABS is a 4-wheel type
which controls the fluid pressure applied to the wheel cylinder of each of the four brakes to prevent each wheel
from getting locked.
The component parts of this ABS includes following parts in addition to those of the conventional brake system.

Wheel speed sensor which senses revolution speed of each wheel and outputs its signal.

In this ABS, ABS hydraulic unit (actuator assembly), ABS control module, pump motor relay and fail-safe relay
are combined as one component.

ABS control module which sends operation signal to ABS hydraulic unit to control fluid pressure applied to each
wheel cylinder based on signal from each wheel speed sensor so as to prevent wheel from locking.

ABS hydraulic unit which operates according to signal from ABS control module to control fluid pressure applied
to wheel cylinder of each of 4 wheels.

Fail-safe (solenoid valve) relay which supplies power to solenoid valve in ABS hydraulic unit and pump motor
relay.

Pump motor relay which supplies power to pump motor in ABS hydraulic unit.

ªABSº warning lamp which lights to inform abnormality when system fails to operate properly.

G sensor which detects body deceleration speed. (For 4WD model only)
This ABS is equipped with Electronic Brake force Distribution (EBD) system that controls a fluid pressure of rear
wheels to best condition, which is the same function as that of proportioning valve, by the signal from wheel sensor
independently of change of load due to load capacity and so on. And if the EBD system fails to operate properly,
the brake warning lamp lights to inform abnormality.

ABS HYDRAULIC UNIT/CONTROL MODULE
ASSEMBLY
ABS control module is a component of ABS hydrauli unit / control
module assembly and has the following functions.
Self-Diagnosis Function
ABS control module diagnoses conditions of the system compo-
nent parts (whether or not there is any abnormality) all the time and
indicates the results (warning of abnormality occurrence and DTC)
through the ªABSº warning lamp as described below.
1) When ignition switch is turned ON, ªABSº warning lamp lights for
2 seconds to check its bulb and circuit.
2) When no abnormality has been detected (the system is in good
condition), ªABSº warning lamp turns OFF after 2 seconds.
3) When the vehicle starts to move after the ignition switch is turned
ON (more than one wheel speed sensor signals are inputted),
solenoid valves and motor of ABS hydraulic unit operate once
one after another for electrical check.
During this check, motor operation sound may be heard but that
means nothing abnormal.
4) When an abnormality in the system is detected, ªABSº warning
lamp lights and the area where that abnormality lies is stored in
the memory of EEPROM in ABS control module.
5) When Diag. switch terminal of diagnosis connector (monitor
connector) is grounded, the abnormal area is output as DTC. It
is indicated by flashing of ªABSº warning lamp. (Refer to the
table below. )

Also ABS control module turns ON EBD warning lamp (brake warn-
ing lamp) depending on the trouble that detected by the module and
EBD warning lamp does not indicate DTC as well as ªABSº warning
lamp.
Fail-Safe Function
When an abnormality occurs (an abnormal DTC is detected), ABS
control module turns OFF the fail-safe relay which supplies power
to ABS hydraulic unit. Thus, with ABS not operating, brakes func-
tion just like the brake system of the vehicle not equipped with ABS.
