11. Remove the clutch balancer and forward clutch re-
turn spring.
WARNING : USE CAUTION WHEN REMOVING COM-
PONENTS WITH COMPRESSED AIR OR PERSONAL
INJURY MAY RESULT.
12. Install the forward and reverse multiple disc clutch
on the transaxle rear cover.
13. Apply 392 kPa (57 psi) of compressed air to the
transaxle rear cover to remove the forward clutch
piston.
Notice : Blowing off the air may cause the piston’s jump–
out.When removing the piston, hold it with your hand using
a waste cloth.
Notice : Take care not to splash ATF when air–blowing.
S When the piston can not be removed as it is
slanted, either blow the air again with the pro-
truding side pushed or remove the piston using
a needle nose pliers with vinyl tape on the tip.
WARNING : USE CAUTION WHEN REMOVING COM-
PONENTS WITH COMPRESSED AIR OR PERSONAL
INJURY MAY RESULT.
14. Apply 392 kPa (57 psi) of compressed air to the
transaxle rear cover to remove the forward clutch
drum.
Notice : Blowing off the air may cause the drum’s jump–
out. When removing the drum, hold it with your hand using
a waste cloth.
Notice : Take care not to splash ATF when air–blowing.
S When the drum can not be removed as it is

General Operation
The control module self–diagnoses SSPS system. If there
is any malfunction, the warning lamp comes ON and at the
same time a trouble code is set. The trouble code can be
retrieved or cleared only by SCANTOOL.
In normal condition, If the ignition is turned on, the warning
lamp comes on for the first 2 sec and out. During this 2 sec,
the control module is diagnosing SSPS system, so a driver
can feel a little heavy steering effort.
If the warning lamp stays on after the 2 sec or comes on
afterward, it means there is a malfunction and a related
trouble code is recorded.
The warning lamp once come on does not go off even if the
malfunction is cleared. It goes off after ignition is turned off
and on without a malfunction.However the trouble code still remains in the control mod-
ule.

The control module is installed on the right side of the au-
dio and can be accessible after the glove box is removed.
It receives signals from the vehicle speed sensor and the
steering wheel rotation sensor and processes them to de-
cide proper fluid flow through the actuator.
It also has a self–diagnosis. If it detects any malfunction,
it starts default mode, which is basically actuator full open
for light steering effort.

GENERAL DESCRIPTION
AND SYSTEM OPERATION
DRIVER SEAT BELT WARNING
The driver’s safety belt incorporates a safety belt reminder
light in the instrument cluster to remind the driver if the
safety belt is not fastened when the the ignition is turned
ON.
THREE–POINT ELR FRONT SEAT
BELT WITH PRETENSIONER
The three–point emergency locking retractor (ELR) front
seat belt pretensioner is always unlocked, allowing the
passenger freedom of movement, except in emergencies
such as rapid deceleration, rapid acceleration, or hard cor-
nering maneuvers.
The front seat belt pretensioner contains an ignitor charge
and a gas generator to inflate the pretensioner. The pre-
tensioner also includes wiring and a connector. The con-
nector of the pretensioner contains a shorting bar which
short–circuits the pretensioner high circuit to the preten-
sioner low circuit when the connector is disconnected. The
shorting bar prevents current from traveling through the
pretensioner during servicing. The shorting bar disen-
gaged when the connecotr is connected.
The pretensioner is an electronically controlled pyrotech-
nical reactor which reduce seat belt slack when it is actived
with air bags.
The front seat belt pretensioner must be replaced after an
accident that cause its activation.
THREE–POINT CLR (ELR) REAR
OUTBOARD SEAT BELT
The rear outboard seating positions use the three–point
child locking retractor (CLR) or emergency locking retrac-
tor (ELR) seat belts. The three–point CLR (ELR) seat beltis always unlocked, allowing the passenger freedom of
movement, except in emergencies such as rapid decel-
eration, rapid acceleration, or hard cornering maneuvers.
OPERATIONAL AND FUNCTIONAL
CHECKS
CAUTION :
S Keep sharp objects and potentially damaging
objects away from the seat belts.
S Avoid bending or damaging any portion of the
buckle or the latch plate.
S Do not bleach or dye the belt webbing. Use
only mild soap and water in order to clean the
belts.
S When installing the seat belt anchor bolts and
the screws, start the bolts and the screws by
hand in order to prevent cross–threading.
S Do not attempt any repairs on the retractor
mechanisms or the covers. Replace any defec-
tive assemblies with new assemblies.
S Replace any belts that are cut or damaged in
any way.
1. Inspect all seat belt anchor bolts and the screws in
order to verify that they are secure.
2. Inspect the seat belt buckle. The buckle must lock
and unlock easily.
3. After inserting the latch into the buckle, tug sharply
on the belt. The buckle must remain locked.
4. Fully extend the shoulder belt portion to make sure
that there is no twisting or tears in the belt.
5. Let the shoulder belt retract fully. The belt should
retract easily.
CHILD SEAT TETHER ANCHOR
For notch back vehicle, there are three child seat tether
anchors located on the read deck lid sill plate. For hatch
back vehicle, there are three child seat fether anchors on
the lower rear tail member in the luggage compartment.
And there are 4 lower child anchors under the rear seat.
4 circular discs on the rear seat indicate the location of the
lower child anchors.
