Service Precaution
WARNING: THIS VEHICLE HAS A SUPPLEMENTAL
RESTRAINT SYSTEM (SRS). REFER TO THE SRS
COMPONENT AND WIRING LOCATION VIEW IN
ORDER TO DETERMINE WHETHER YOU ARE
PERFORMING SERVICE ON OR NEAR THE SRS
COMPONENTS OR THE SRS WIRING. WHEN YOU
ARE PERFORMING SERVICE ON OR NEAR THE SRS
COMPONENTS OR THE SRS WIRING, REFER TO
THE SRS SERVICE INFORMATION. FAILURE TO
FOLLOW WARNINGS COULD RESULT IN POSSIBLE
AIR BAG DEPLOYMENT, PERSONAL INJURY, OR
OTHERWISE UNNEEDED SRS SYSTEM REPAIRS.
CAUTION: Always use the correct fastener in the
proper location. When you replace a fastener, use
ONLY the exact part number for that application.
ISUZU will call out those fasteners that require a
replacement after removal. ISUZU will also call out
the fasteners that require thread lockers or thread
sealant. UNLESS OTHERWISE SPECIFIED, do not
use supplemental coatings (Paints, greases, or
other corrosion inhibitors) on threaded fasteners or
fastener joint interfaces. Generally, such coatings
adversely affect the fastener torque and the joint
clamping force, and may damage the fastener. When
you install fasteners, use the correct tightening
sequence and specifications. Following these
instructions can help you avoid damage to parts and
systems.
General Description
Intellignet suspension control uses a microcomputer as a
control unit to judge running conditions including engine
revolution from Powertrain Control Module, vehicle speed
from vehicle speed sensor, a brake switch signal, and
vertical and lateral G-sensor signal, then sets optimum
damping force so that best running stability can be
achieved.

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.
