Inspection and Repair
Make necessary correction or parts replacement if wear,
damage, or any other abnormal condition are found
through inspection.
Pressure Plate Assembly

1. Visually check the pressure plate friction surface for
excessive wear and heat cracks.
2. If excessive wear or deep heat cracks are present,
the pressure plate must be replaced.

Removal
1. Disconnect the battery ground cable.
2. Remove the instrument panel driver lower cover(5).
Refer to the Instrument Panel Assembly in Body
Structure section.
3. Remove seven screws to remove the steering
cowl(4).
4. Disconnect the SDM (air bag controller) connector
located at lower of the instrument panel driver lower
cover.
5. Remove four fixing screws and disconnect the driver
inflator module connector to remove the driver inflator
module(3).
CAUTION: When carrying a live inflator module,
make sure the bag opening is pointed away from
you. In case of an accidental deployment, the bag will
then deploy with minimal chance of injury. Never
carry the inflator module by the wires or connector
on the underside of the module.
When placing a live inflator module on a bench or
other surface, always face the bag and trim cover up,
away from the surface. This is necessary so that a
free space is provided to allow the air bag to expand
in the unlikely event of accidental deployment.
6. Remove the steering wheel(2).
Refer to the Steering Wheel in Steering section.
7. Disconnect the SRS coil assembly connector,
remove four fixing screws to remove the SRS coil
assembly(1).
8. Disconnect the lighting switch connector, remove four
fixing screws to remove the lighting switch(6).

Installation
To install, follow the removal steps in the reverse order,
noting the following points.1. Check to see if the vehicle is in the straight driving
condition and turn the rotary section of the SRS coil
assembly provided to the upper surface of the lighting
switch (combination switch) counterclockwise fully
until it stops.
Then from where it stops, turn it back about 3
rotations to set the alignment marks(7) together
before installing the steering wheel.

2. Tighten the steering shaft nut to the specified torque.
Torque: 34 N·m (3.5 kg·m/25 lb ft)
3. When connect the double lock type of inflator module
connector, insert the connector completely and lock
at outside.
Imperfect locking may cause malfunction of SRS
system circuit.
4. When installing the steering cowl(11), be sure to pass
the harnesses through the route as shown in the
figure so that the starter switch harness(8), the
combination switch harness(9) and inflator module
harness(10) will not get caught.
