ANTI±LOCK BRAKE SYSTEM (A.B.S.)
Description
wThe A.B.S. is a brake system which controls the wheel cylinder hydraulic pressure of all four wheels during
sudden braking and braking on slippery road surfaces, preventing the wheels from locking. This A.B.S.
provides the following benefits:
(1) Enables steering round an obstacle with a greater degree of certainty even when panic braking.
(2) Enables stopping in a panic brake while keeping the effect upon stability and steerability to a mini-
mum, even on curves.
wThe function of the A.B.S. is to help maintain directional stability and vehicle steerability on most road
conditions. However, the system cannot prevent the vehicle from skidding if the cornering speed limit is
exceeded.
wThe A.B.S. has a longitudinal deceleration sensor to match braking characteristics to the full±time four±
wheel drive. (For 4WD)
wIn case a malfunction occurs, a diagnosis function and fail±safe system have been adopted for the A.B.S.
to increase serviceability.

4. INSPECT SENSOR SIGNAL LEVEL
Drive the vehicle straight ahead at about 4 ±6 km/h (2.5
± 3.7 mph), and check that the warning light turns on after
a 1 second pause.
If the warning light turns on without blinking when the ve-
hicle speed is not within the specified speed range above,
stop the vehicle and read the diagnostic code, and repair
the malfunctioning parts.
(See step S on page BR±79)
HINT: If the warning light turns on while the vehicle speed
is within specified speed range above, the check is com-
pleted. And when the vehicle speed exceeds 6 km/h
(3.7mph), the warning light will blink again. In this condi-
tion, speed sensors are OK.
NOTICE: While the warning light is off, do not give any
shocks to vehicle such as acceleration, deceleration, brak-
ing, shift change, steering or shocks from the road condi-
tion.
(4WD)
(a) Remove the rubber cap from the Ts connector lo-
cated in front of the actuator.
(b) Connect the terminals of Ts connector.
(c) Pull the parking brake lever up, and start the engine.
NOTICE: Do not depress the brake pedal.
(d) Check that the warning light blinks about 4 times ev-
ery 1 second as shown.

5. INSPECT SENSOR SIGNAL CHANGE
Drive the vehicle straight ahead at about 45 ± 55 krn/h
(28.0 ± 34.2 mph), and check that the warning light turns
on after a 1 second pause.
If the warning light turns on without blinking when the ve-
hicle speed is not within the specified speed range above,
stop the vehicle and read the diagnostic code, and repair
the malfunctioning .parts.
(See step 6 on this page)
HINT: If the warning light turns on while the vehicle speed
is within specified speed range above, the check is com-
pleted. And when the vehicle speed is not within specified
speed range, the warning light will blink again. In this con-
dition, sensor rotors are OK.
NOTICE: While the warning light is off, do not give any
shocks to vehicle such as acceleration, deceleration, brak-
ing, shift change, steering or shocks from the road condi-
tion.
HINT: The first number of blinks will equal the first digit
of a two digit diagnostic code. After a 1.5 second pause,
the 2nd number of blinks will equal the 2nd number of a
two digit code. If there are two or more codes, there will
be a 2.5 second pause between each code, and then
indication will begin again after a 4.0 second pause,
continuing in order from the smaller value up to the larg-
er one. 6. READ DIAGNOSTIC CODE
Stop the vehicle and disconnect the check connector, and
warning light will begin to blink. Read the number of
blinks.
(See DIAGNOSTIC CODE on page BR±81)
7. REPAIR MALFUNCTIONING PARTS
Repair or replace the malfunctioning parts.
HINT: When repairing or replacing parts, turn the ignition
switch OFF.

FRONT WHEEL ALIGNMENT
1. MAKE FOLLOWING CHECKS AND CORRECT ANY
PROBLEMS
(a) Check the tires for wear, size and proper inflation.
Cold tire inflation pressure:
FWD/SV21 and 4WD 2.1 kg±cm2 (30 psi, 206 kPa)
FWD/VZV21 2.2 kg±cm2 (31 psi, 216 kPa)
(b) Check the front wheel bearings for looseness.
(c) Check the wheel runout.
Lateral runout: Less than 1.0 mm (0.039 in.)
(d) Check the front suspension for looseness.
(e) Check the steering linkage for looseness.
(f) Check that the front shock absorber function properly
by using the standard bounce test.
If the clearance of the vehicle is not standard, try
to level by locking it down. If still not correct, check
for bad springs or suspension parts.
HINT: Before inspecting wheel alignment, adjust
chassis ground clearance to specification.
3. INSTALL WHEEL ALIGNMENT EQUIPMENT
Follow the specific instructions of the equipment
manufacturer. 2. MEASURE CHASSIS GROUND CLEARANCE

If steering angles differ from the standard specifi-
cations, check to see if the lengths of the left and
right tie rods are the same.
HINT: If the tie rod lengths are not equal, the steer-
ing angle cannot be adjusted properly.
If the tie rod lengths were changed to adjust the
wheel angle, reinspect the toe±in.
HINT: Camber is not adjustable, if measurement is not
within specification, inspect and replace the suspen-
sion parts.
6. CHECK STEERING AXIS INCLINATION
Steering axis inclination:
Steering axis inclination is not adjustable,if measure-
ment is not within specification, inspect and replace
the suspension parts.
7. CHECK CASTER
Caster:
If caster is not within specification, adjust by in-
creasing or decreasing the spacers. (See page
