Removal
1. Turn the steering wheel so that the vehicle's wheels
are pointing straight ahead.
2. Turn the ignition switch to ªLOCKº.
3. Disconnect the battery ground cable, and wait at least
5 minutes.
4. Disconnect the yellow 2-way SRS connector located
under the steering column.CAUTION: T h e w heels of the vehicle must be
straight ahead and the steering column in the
ºLOCKº position before disconnecting the steering
wheel. Failure to do so will cause the coil assembly
to become uncentered which will cause damage to
the coil assembly.
5. Remove the engine hood opening lever and steering
lower cover.
6. Remove driver knee bolster (reinforcement).

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.

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.
