2. Install the dash seal retaining ring with the nuts.
Tighten
Tighten the dash seal retaining ring nuts to 7 NSm (62
lb–in).
Important : When attaching the upper universal joint, the
steering wheel must be placed in the straight–ahead posi-
tion with the spokes pointing down.
3. Attach the upper universal joint of the intermediate
shaft onto the steering column.
4. Install the pinch bolt into the upper universal joint
on the intermediate shaft and tighten the bolt.
Tighten
Tighten the upper intermediate shaft pinch bolt to 22
NSm (16 lb–ft).
Important : When attaching the lower universal joint, the
marks on the intermediate shaft and on the stub shaft
should line up.
5. Attach the lower universal joint of the intermediate
shaft onto the steering gear stub shaft.
Important : When installing the lower intermediate shaft
pinch bolt, make sure the bolt goes through the universal
joint on the side of the stub shaft with the notch. If you have
trouble seating the universal joint completely down onto
the stub shaft, rotate the steering wheel slightly while
pushing down on the universal joint.
6. Install the bolt into the lower universal joint on the
intermediate shaft and tighten the bolt.
Tighten
Tighten the lower intermediate shaft pinch bolt to 22
NSm (16 lb–ft).

steering fluid flow. The SSPS control module can change
the amount of current flowing through the EVO actuator by
varying the output duty cycle. If the EVO actuator is dis-
connected, the pintle will be pulled out of the orifice for
maximum power steering assist.
The SSPS control module has the ability to detect faults
in the steering wheel rotation sensor, the EVO actuator, or
the circuitry to those components. Any default detected
will cause the power steering assist to remain at maximum
with the pintle in its normally retracted position for all
speeds.
When the system is operating normally, increasing the ve-
hicle speed will decrease power steering assist, allowing
the driver to have improved road feel and directional stabil-
ity. When sudden steering wheel turns are made, as in
evasive maneuvers, they are detected by the SSPS con-trol module through the steering wheel rotation sensor.
When detected, the SSPS control module reduces current
to the EVO actuator, allowing greater power steering as-
sist.
SSPS (Speed Sensitive Power Steering) is to control pow-
er steering effort properly according to varying conditions
for both convenience and safety.
At low speed or standstill, power steering effort becomes
light to provide easy steering. On the contrary, at high
speed, power steering effort becomes heavy to provide
stable steering.
SSPS offered to LACETTI is EVO (Electric Variable Ori-
fice) type, which controls steering effort by modulating
pressurized fluid supply to the steering unit from the power
steering pump.
Steering wheel rotation sensor is installed at the bottom of
the steering column.
This sensor detects steering wheel rotation which is used
to calculate the angle speed of the steering wheel by
SSPS module.
If the angle speed was big enough for intervention into nor-mal steering force control during high vehicle speed, which
means a driver made an evasive steering maneuver to
avoid an accident, SSPS module would supply enough
steering support.
The sensor consists of a variable resistor.

The flow control actuator is installed on the outlet of the
conventional vein type of the power steering pump. The
actuator modulates fluid flow to the steering gear from the
pump by current control from the SSPS module.
At low speed, small current is supplied to the actuator.
Then the actuator modulates flow high and steering effort
becomes light.
At high speed, On the contrary, big current to the actuator.
Low fluid flow and heavy steering effort.
If there happens an actuator malfunction, by default its
pintle valve opens the orifice 100% to supply light steering
effort.
The maximum pumping pressure with SSPS option is
74.4~81.6 kg/cm2.
If you try to measure voltage at the actuator terminal with
the connector removed, you can measure 6.5V.

The control module is installed on the right side of the au-

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
STEERING WHEEL AND COLUMN
CAUTION : To ensure the energy–absorbing action of
the steering column, it is important to use only the
specified screws, bolts, and nuts, tightened to the
specified torque.
In addition to the steering function, the steering column
provides safety and security.
The energy–absorbing column is designed to compress in
a front–end collision to lessen the chance of driver injury.
The ignition switch and the lock are mounted on the col-
umn, allowing the ignition and steering operations to be
locked to inhibit theft of the car.
The column levers trigger the turn signals, the headlight
beams, and the windshield washer and wipers.The tilt steering column uses telescopic function to allow
the steering wheel to tilt up and down in and out. This en-
ables the driver to adjust the steering wheel to a comfort-
able position.
Notice : Apply a thin coat of lithium grease to all friction
points when reassembling.
The column may be disassembled and reassembled easi-
ly.IGNITION KEY REMINDER
The ignition key reminder alerts the driver that the key is
still in the ignition when the driver attempts to exit the ve-
hicle.
An internal switch in the ignition lock cylinder supplies bat-
tery voltage to the reminder chime module when all of the
following conditions are true:
S The key is in the ignition switch.
S The ignition is OFF.
S The driver’s door is open.
For information on removal and installation of the reminder
chime module, refer to Section 9E, Instrumentation/Driver
Information.

CAUTION : Disconnect the negative battery cable before removing or installing any electrical unit or when a tool
or equipment could easily come in contact with exposed electrical terminals. Disconnecting this cable will help
prevent personal injury and damage to the vehicle. The ignition must also be in LOCK unless otherwise noted.
