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

821R100017

Vehicles 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 turn“ON” the warning lamp.

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
the“Basic Diagnosis Flowchart” 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:

D

Box Wrench

D

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 “ON”
position.Before removing or connecting battery cables,
fuses or connectors, always turn the ignition switch to
the“OFF” 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.

D

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.

D

The Control Unit connectors should never be
connected or disconnected with the ignition“ON”.

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-34) located left side of
instrument panel.
