6) Remove contact coil and combination switch assembly from
steering column.
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.

REMOVAL
WARNING:
Never rest a steering column assembly on the steering
wheel with air bag (inflator) module face down and column
vertical. Otherwise personal injury may result.
1) Disconnect negative battery cable at battery terminal.
2) Disable air bag system. Refer to ªDISABLING AIR BAG SYS-
TEMº under ªSERVICE PRECAUTIONSº in Section 10B.
3) Remove steering wheel and contact coil and combination switch
assembly, if necessary. Refer to ªSTEERING WHEELº and
ªCONTACT COIL AND COMBINATION SWITCH ASSEMBLYº
in this section.
Perform the following procedure if not removing steering wheel
and/or combination switch.
ii) Turn steering wheel so that vehicle's front tires are at straight-
ahead position.
ii) Turn ignition switch to ªLOCKº position and remove key.
4) Remove steering column hole cover.
5) Disconnect all connectors for the following parts.

Contact coil and combination switch

Ignition switch
6) Make alignment marks on shaft joint and shaft (column side) for
a guide during reinstallation.
7) After removing bolt on column side of shaft joint and loosening
bolt on its lower shaft assembly side, move shaft joint to lower
shaft assembly side (in arrow direction in the figure).

TABLE ± A ªABSº WARNING LAMP CIRCUIT CHECK ± LAMP DOES NOT
COME ªONº AT IGNITION SWITCH ON
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.
