STEERING WHEEL
CAUTION:
Removal of the steering wheel allows the contact coil to turn
freely but do not turn the contact coil (on the combination
switch) more than allowable number of turns (about two and
a half turns from the center position clockwise or counter-
clockwise respectively), or coil will break.
REMOVAL
1) Remove driver air bag (inflator) module from steering wheel re-
ferring to ªDRIVER AIR BAG (INFLATOR) MODULEº earlier in
this section.
2) Remove steering shaft nut.
3) Make alignment marks on steering wheel and shaft for a guide
during reinstallation.
4) Remove steering wheel with special tool.
Special Tool
(A): 09944-36011
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.
CENTERING CONTACT COIL
1) Check that vehicle's wheels (front tires) are set at straight-ahead
position.
2) Check that ignition switch is at ªLOCKº 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 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.

INSTALLATION
1) Check that vehicle's front tires are at straight-ahead position and
contact coil is centered. Refer to ªCENTERING CONTACT
COILº in this section.
CAUTION:
These two conditions are prerequisite for installation of
steering wheel. If steering wheel has been installed with-
out these conditions, contact coil will break when steer-
ing wheel is turned.
2) Install steering wheel to steering shaft with 2 lugs on contact coil
fitted in two grooves in the back of steering wheel and also align-
ing marks on steering wheel and steering shaft.
3) Tighten steering shaft nut to specified torque.
Tightening Torque
(a): 33 N
.m (3.3 kg-m, 23.5 lb-ft)
4) Install driver air bag (inflator) module to steering wheel. Refer to
ªDRIVER AIR BAG (INFLATOR) MODULEº in this section.
CONTACT COIL AND COMBINATION SWITCH
ASSEMBLY
CAUTION:
Do not turn contact coil (on combination switch) more than
allowable number of turns (about two and a half turns from
the center position clockwise or counterclockwise respec-
tively), or coil will break.
REMOVAL
1) Remove steering wheel from steering column. Refer to
ªSTEERING WHEELº in this section.
2) Remove steering column hole cover.
3) Remove steering column cover screws (3 pieces).
4) Separate upper cover and lower cover, then remove them.
5) Disconnect all connectors for contact coil and combination
switch assembly.

INSPECTION
Check contact coil and combination switch wire harness for any
signs of scorching, melting or other damage. If it is damaged, re-
place.
INSTALLATION
1) Check to make sure that vehicle's front tires are set at straight-
ahead position and then ignition switch is at ªLOCKº position.
2) Install contact coil and combination switch assembly to steering
column.
NOTE:
New contact coil and combination switch assembly is sup-
plied with contact coil set and held at its center position
with a lock pin and seal. Remove this lock pin after installing
contact coil and combination switch assembly to steering
column.

3) Connect all connectors that have been removed in removal.
4) Install steering column upper and lower cover, and then tighten
steering column cover screws.
CAUTION:
When installing lower cover and upper cover, be careful
so that contact coil and combination switch lead wire is
not caught between covers.
5) Install steering column hole cover.
6) Install steering wheel to steering column. Refer to ªSTEERING
WHEELº in this section.
STEERING COLUMN
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 above damage could impair the column's col-
lapsible design.
When loosening steering column mounting bolts, make
sure that steering column assembly and steering shaft low-
er assembly have been separated. Loosening them with
steering column assembly and steering shaft lower assem-
bly assembled could cause damage to bearing in steering
shaft lower assembly.
NOTE:
When servicing steering column or any column-mounted
component, remove steering wheel. But when removing steer-
ing column simply to gain access to instrument panel compo-
nents, leave steering wheel installed on steering column.

CIRCUIT DESCRIPTION
Operation (ON / OFF) of the ªABSº warning lamp is controlled by the ABS control module and ABS lamp driver mod-
ule.
If the Antilock brake system is in good condition, the ABS control module turns the ªABSº warning lamp ON at the
ignition switch ON, keeps it ON for 2 seconds only and then turns it OFF. If an abnormality in the system is detected,
the lamp is turned ON by ABS control module. Also, it is turned ON by ABS lamp driver module when the connector
of the ABS control module was disconnected.
