General Description
The rear suspension is a 5-link, coil spring type
suspension with a stabilizer bar, consisting of two trailing
links, two upper links, lateral rod, shock absorber, and
stabilizer. In this suspension, the links are specially
arranged to enable the rear axle to move freely, thereby
expanding suspension stroke, reducing friction, and
improving lateral rigidity and roll control. All these result in
improved stability, riding comfort, and rough road
maneuverability.
Each link connects the axle housing with the frame
through a runner bushing. The axle housing is supported
by the trailing links and upper links longitudinally and by
the lateral rod latitudinally.

3E±12WHEEL AND TIRE SYSTEM
Tire
Tire Replacement
When replacement is necessary, the original metric tire
size should be used. Most metric tire sizes do not have
exact corresponding alphanumeric tire sizes. It is
recommended that new tires be installed in pairs on the
same axle. If necessary to replace only one tire, it should
be paired with tire having the most tread, to equalize
braking traction.
CAUTION: Do not mix different types of tires such
as radial, bias and bias-belted tires except in
emergencies, because vehicle handling may be
seriously affected and may result in loss of control.
Tire Dismounting
Remove valve cap on valve step and deflate the tire. Then
use a tire changing machine to mount or dismount tires.
Follow the equipment manufacturer's instruction. Do not
use hand tools or tire lever alone to change tires as they
may damage the tire beads or wheel rim.
Tire Mounting
Rim bead seats should be cleaned with a wire brush or
coarse steel wool to remove lubricants, and light rust.
Before mounting a tire, the bead area should be well
lubricated with an approved tire lubricant.
After mounting, inflate the tire to 196kPa (28 psi) so that
beads are completely seated. Inflate the air to specified
pressure and install valve cap to the stem.
WARNING: NEVER STAND OVER TIRE WHEN
INFLATING. BEAD MAY BREAK WHEN BEAD SNAPS
OVER RIM'S SAFETY HUMP AND CAUSE SERIOUS
PERSONAL INJURY.
NEVER EXCEED 240 KPA (35 PSI) PRESSURE WHEN
INFLATING. IF 240 KPA (35 PSI) PRESSURE WILL
NOT SEAT BEADS, DEFLATE, RE-LUBRICATE AND
RE-INFLATE. OVER INFLATION MAY CAUSE THE
BEAD TO BREAK AND CAUSE SERIOUS PERSONAL
INJURY.
Tire Repair
There are many different materials on the market used to
repair tires.
Manufacturers have published detailed instructions on
how and when to repair tires. These instructions can be
obtained from the tire manufacturer if they are not
included with the repair kit.
Wheel Inspection
Damaged wheels and wheels with excessive run-out
must be replaced.
Wheel run out at rim (Base on hub Bore):
Aluminum
1± Vertical play: Less than 0.55 mm (0.022 in)
2± Horizontal play: Less than 0.55 mm (0.022 in)
480RS012
General Balance Procedure
Deposits of mud, etc. must be cleaned from the inside of
the rim.
The tire should be inspected for the following: match
mount paint marks, bent rims, bulges, irregular tire wear,
proper wheel size and inflation pressure. Then balance
according to the equipment manufacturer's
recommendations.
There are two types of wheel and tire balance.
Static balance is the equal distribution of weight around
the wheel.
Assemblies that are statically unbalanced cause a
bouncing action called tramp. This condition will
eventually cause uneven tire wear.

WHEEL AND TIRE SYSTEM3E±13

Legend
(1) Heavy Spot Wheel Shimmy
(2) Add Balance Weights Here
Dynamic balance is the equal distribution of weight on
each side of the wheel center-line so that when the tire
spins there is no tendency for the assembly to move from
side to side. Assemblies that are dynamically unbalanced
may cause shimmy.

SPIN BALANCING AND TO OBTAIN A GOOD
BALANCE.
Balancing Wheel and Tire
On-vehicle Balancing
On-Vehicle balancing methods vary with equipment and
tool manufacturers. Be sure to follow each
manufacturer's instructions during balancing operation.
Off-vehicle Balancing
Most electronic off-vehicle balancers are more accurate
than the on-vehicle spin balancers. They are easy to use
and give a dynamic balance. Although they do not correct
for drum or disc unbalance (as on- vehicle spin balancing
does), they are very accurate.

System Components
Control Unit, 3 Vertical G-sensors, Lateral G-sensor, 4
Actuators, 4 Adjustable Damping Force Shock
Absorbers, and Warning Lamp.
Control Unit
The Control Unit consists of Adjustable Damping Force
Shock Absorber control circuits, fault detector, and a
fail-safe. It drives the actuator according to the signal
from each sensor.
The Control Unit has a self-diagnosing function which can
indicate faulty circuits during diagnosis.
The Control Unit is mounted in the center of the
instrument panel.
Actuator
Front actuators installed on front shock absorbers and
rear actuator installed inside rear shock absorbers control
damping force of shock absorber by the Control Unit
signal.
Adjustable Damping Force Shock
Absorber
This type shock absorber is used in front and rear
intelligent suspension. According to running condition the
Control Unit changes shock absorber damping force and
obtains good running stability.
Warning Lamp
821R200011Vehicles equipped with the Intelligent Suspension Control
have an amber warning lamp in the instrument panel. The
warning lamp will illuminate if a malfunction in the
Intelligent Suspension Control is detected by the Control
Unit. In case of an important electronic malfunction, the
Control Unit will turnªONº the warning lamp.

INTELLIGENT SUSPENSION3F±5
Vertical G-Sensor
Front G-sensors installed inside front actuators and the
rear G-sensor installed on the rear left frame side detect
the vehicle vertical gravity and send a signal to the Control
Unit.
Lateral G-Sensor
The G-sensor installed inside the Control Unit detects the
vehicle turning speed and sends a signal to the Control
Unit.

General Diagnosis
General Information
Intelligent Suspension Control troubles can be classified
into two types, those which can be detected by the
warning lamp and those which can be detected as a
vehicle abnormality by the driver.
In either case, locate the fault in accordance with
theªBASIC DIAGNOSTIC FLOWCHARTº and repair.
Please refer to
Section 3 for the diagnosis of mechanical
troubles such as abnormal noise, vehicle pulls, excessive
tire wear, wheel hop and shimmy, shake or vibration.
Service Precautions
Required Tools and Items:

Box Wrench

Special Tool
Some diagnosis procedures in this section require the
installation of a special tool.
J-39200 High Impedance Multimeter
When circuit measurements are requested, use a
circuit tester with high impedance.
Computer System Service Precautions
The Intelligent Suspension Control interfaces directly
with the Control Unit which is a control computer that is
similar in some regards to the Powertrain Control Module.
These modules are designed to withstand normal current
draws associated with vehicle operation. However care
must be taken to avoid overloading any of the Control Unit
circuits. In testing for opens or shorts, do not ground or
apply voltage to any of the circuits unless instructed to do
so by the appropriate diagnostic procedure. These
circuits should only be tested with a high impedance
multimeter (J-39200) or special tools as described in this
section. Power should never be removed or applied to
any control module with the ignition in the ªONº
position.Before removing or connecting battery cables,
fuses or connectors, always turn the ignition switch to
theªOFFº position.
General Service Precautions
The following are general precautions which should be
observed when servicing and diagnosing the Intelligent
Suspension Control and/or other vehicle systems. Failure
to observe these precautions may result in Intelligent
Suspension Control damage.

If welding work is to be performed on the vehicle using
an electric arc welder, the Control Unit connectors
should be disconnected before the welding operation
begins.

The Control Unit connectors should never be
connected or disconnected with the ignitionªONº.
Parts Handling
Be careful when handling the actuator, control unit, or
G-sensor. They should not be dropped or thrown,
because the semi-conductor G-sensor tip damage may
result.

FLASHING CODES
1. ON BOARD DIAGNOSIS (SELF-DIAGNOSIS)
1. The Control Unit conducts a self-test of most of the
wiring and components in the system each time the
key is turned ON. If a fault is detected the Control
Unit will store a Diagnostic Trouble Code (DTC) in
memory. It's a number that corresponds to a
specific problem.
2. When the problem detected is important: the
warning lamp turns on until the fault is repaired and
the Control Unit memory is cleared.
2. DIAGNOSTIC TROUBLE CODES (DTC)
1. DTC can be expressed by flashing times of warning
lamp by shorting together terminals 3 and 4 or 5 of
the Diagnosis Connector (C-39) located left side of
instrument panel.

4: Actuator Rear LH, Lateral G-sensor
2. After this, the warning lamp will be OFF for 3.5
seconds and then will flash each DTC.
a. When there are more than 9 flashes this means
that the indicator is constantly flashing, OFF for
4 seconds ON for 0.5 seconds. In this case there
is no DTC stored in memory.
b. When there are less than 9 flashes you will see
DTC codes in ascending order.
CLEAR DTC
Remark: If you clear the DTC (Diagnosis Trouble Codes)
you will not be able to read any codes recorded during the
last Trouble.
Remark: To be able to use the DTC again to identify a
problem you will need to reproduce the fault or the
problem. This may require a new test drive or just turning
the ignition on (this depends on the nature of the fault).
1. Short the Diagnosis Connector C-39 terminal 3 to
terminal 4 or 5 (ground).

IF it is flashing and the flash is 0.5 seconds ON and 4
seconds OFF without interruption, this means that
there is no DTC. The DTCs are already cleared.
350R200002
2. IF a code is flashed, wait until the lamp is flashing.
3. Conduct brake switch ON/OFF 6 or more times on
condition that one operation is within 2 seconds.
