Steering Wheel Removal and InstallationS6RW0D6206002
CAUTION!
Do not turn the contact coil more than
allowable number of turns (about two and a
half turns from the center position clockwise
or counterclockwise respectively) with
steering wheel removed, or coil will break.

Removal
CAUTION!
Do not hammer the end of the shaft.
Hammering it will loosen the plastic shear
pins which maintain the column length and
impair the collapsible design of the column.

1) Disconnect negative (–) cable at battery.
2) Disable air bag system referring to “Disabling Air
Bag System in Section 8B”.
3) Remove driver air bag (inflator) module from
steering wheel. Refer to “Driver Air Bag (Inflator)
Module Removal and Installation in Section 8B”.
4) Disconnect horn connector and audio control switch
connector, if equipped.
5) Remove steering shaft nut and then make alignment
marks (1) on steering wheel and shaft for a guide
during reinstallation.6) Remove steering wheel using special tool.
Special tool
(A): 09944–36011
InstallationCAUTION!
Following 2 Steps (Step 1) and 2)) are
prerequisite for installation of steering wheel.
If steering wheel has been installed without
these 2 Steps, contact coil will break when
steering wheel is turned.

1) Check that vehicle’s front tires are at straight-ahead
position and contact coil is centered. If contact coil is
turned after removing steering wheel, center contact
coil referring to “Centering Contact Coil Cable
Assembly”.
2) Install steering wheel to steering shaft with 2 grooves
(1) on contact coil fitted in 2 lugs (2) in the back of
steering wheel and also aligning marks (3) on
steering wheel and steering shaft.
3) Tighten steering shaft nut (4) to specified torque.

number of turns (about two and a half turns
from the center position clockwise or
counterclockwise respectively), or coil will
break.

Removal
1) Disconnect negative (–) cable at battery.
2) Disable air bag system referring to “Disabling Air
Bag System in Section 8B”.
3) Remove steering wheel from steering column
referring to “Steering Wheel Removal and
Installation”.

3) Install steering column upper cover (1) and lower
cover (2).
CAUTION!
When installing covers, be careful so that
each lead wire is not caught between covers.
Otherwise, each lead wire is damaged.

Centering Contact Coil Cable AssemblyS6RW0D6206004
1) Check that vehicle’s wheels (front tires) are set at
straight-ahead position.
2) Check that ignition switch is at LOCK position.
3) Turn contact coil counterclockwise slowly with a light
force till contact coil will not turn any further.
NOTE
Contact coil can turn about 5 turns at the
maximum, that is, if it is at the center
position, can turn about two and a half turns
both clockwise and counterclockwise.

4) From the position where contact coil became unable
to turn any further (it stopped), turn it back clockwise
about two and a half rotations and align center mark
with alignment mark (1).
Contact Coil Cable Assembly InspectionS6RW0D6206005
Refer to “Contact Coil Cable and Its Circuit Check in
Section 8B”.
Steering Column Removal and InstallationS6RW0D6206008
CAUTION!
Once the steering column is removed from
the vehicle, the column is extremely
susceptible to damage.
• Dropping the column assembly on its end
could collapse the steering shaft or loosen
the plastic shear pins which maintain
column length.
• Leaning on the column assembly could
cause it to bend or deform.
Any of the damage could impair the column’s
collapsible design.
Steering column mounting nuts should not
be loosened with steering shaft joint upper
side bolt tightened as this could cause
damage to shaft joint bearing.

NOTE
When servicing steering column or any
column-mounted component, remove
steering wheel. But when removing steering
column simply to gain access to instrument
panel components, leave steering wheel
installed on steering column.

Air Bag (Inflator) Module and Seat Belt
Pretensioner Disposal
S6RW0D8206018
WARNING!
Failure to follow proper air bag (inflator)
module and seat belt pretensioner disposal
procedures can result in air bag deployment
and pretensioner activation which may cause
personal injury. Do not dispose of live
(undeployed) air bag (inflator) modules and
seat belt pretensioners. Because undeployed
air bag (inflator) module / inactivated seat
belt pretensioner must not be disposed of
through normal refuse channels. Undeployed
air bag (inflator) module and inactivated seat
belt pretensioner contain substances that
can cause severe illness or personal injury if
sealed container is damaged during disposal.

Air bag (inflator) module / seat belt pretensioner can be
deployed / activated inside or outside of vehicle.
Deployment / Activation method used depends upon
final disposition of vehicle. Review the following
instructions in order to determine which will work best in
a given situation.
Deployment / Activation Outside of Vehicle: When you
intend to return the vehicle to service, deploy the air bag
(inflator) module(s) and/or activate seat belt
pretensioner(s) outside of the vehicle.
Deployment / Activation Inside of Vehicle: When the
vehicle will be destroyed, or salvaged for component
parts, deploy the air bag module(s) and/or activate seat
belt pretensioner(s) installed on vehicle.
WARNING!
The following precautions must be observed
for this work. Failure to observe any of them
may result in personal injury.
• Procedure should be followed strictly as
described here.
• Be sure to read “Precautions on Service
and Diagnosis of Air Bag System”
beforehand.
• To avoid accidental deployment /
activation, this work should be performed
by no more than one person.
• Since smoke is produced when air bag
(inflator) module is deployed and
pretensioner is activated, select well-
ventilated area.
• Air bag (inflator) module and seat belt
pretensioner will immediately deploy /
activate when 12 volts vehicle battery is
connected to it. Wear safety glasses
throughout this entire deployment /
activation and disposal procedure.
• Wear suitable ear protection when
deploying air bag (inflator) module /
activating seat belt pretensioner. Also,
advise those who are in area close to
deployment / activation site to wear
suitable ear protection.
• Do not deploy / activate two or more air
bag system components (air bag (inflator)
modules and seat belt pretensioners) at
the same time.
• Never connect deployment harness to any
12 volts vehicle battery before connecting
deployment harness to air bag (inflator)
module and seat belt pretensioner.
Deployment harness shall remain shorted
and not be connected to 12 volts vehicle
battery till you are ready to deploy air bag
(inflator) module or activate seat belt
pretensioner.

• For side-air bag (inflator) module
a. Remove sleeve (1) and sleeve lock nut (2), if
equipped.
b. Clear space (3) on ground about 185 cm (6 ft)
in diameter where side-air bag (inflator)
module for deployment. Paved, outdoor
location where there is no activity is preferred.
If outdoor location is not available, space on
shop floor where there is no activity and
provide sufficient ventilation. Ensure no loose
or flammable objects are within deployment
area.
c. Place deployment fixture (A) on ground.
Special tool
(A): 09932–75041
d. Fill plastic reservoir in deployment fixture (A)
with water or sand. This is necessary to
provide sufficient stabilization of fixture during
deployment.
e. Attach side-air bag (inflator) module (1) in
deployment fixture using mounting
attachment, sleeve lock nut and washer (2).
NOTE
Make sure that deploying direction faces as
shown in the figure against mounting
attachment.

• For side curtain-air bag (inflator) module
a. Cut off bag (1) of side curtain-air bag (inflator)
module.
b. Tie side curtain-air bag inflator (1) to tire (3)
with wire harness (2) as shown.
Wire harness specifications
Stripped wire harness section 1.25 mm2
(0.0019 in.2) or more (Stripped wire harness
diameter 1.25 mm (0.05 in.) or more)
CAUTION!
Make sure that wire harness is tight. It is very
dangerous if looseness in wire harness
results in side curtain-air bag inflator flying
off due to shock from inflator deploying.

NOTE
Wind wire harness (2) around at least 3 times.

c. Clear space (5) on ground about 185 cm (6 ft)
in diameter where side curtain-air bag
(inflator) module (1) is set for deployment.
Paved, outdoor location where there is no
activity is preferred. If outdoor location is not
available, use space on shop floor where
there is no activity and sufficient ventilation is
provided. Ensure no loose or flammable
object exists within activation area.
d. Pile tire with side curtain-air bag (inflator)
module on tire (4).
