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.

6) If contact coil and combination switch assembly is removed,
install it, referring to ªCONTACT COIL AND COMBINATION
SWITCH ASSEMBLYº in this section.
7) Connect all connectors that have been removed in removal.
8) Install steering column hole cover.
9) If steering wheel is removed, install it by referring to ªSTEER-
ING WHEELº in this section.
10) Connect negative battery cable.
11) After installing steering column assembly, be sure to enable air
bag system by referring to ªENABLING AIR BAG SYSTEMº un-
der ªSERVICE PRECAUTIONSº in Section 10B.

CAUTION:
Never turn steering wheel while steering lower shaft assem-
bly is removed.
Should it have been turned and contact coil (on combina-
tion switch) have got out of its centered position, it needs
to be centered again. Also, turning steering wheel more
than about two and a half turns will break contact coil.
REMOVAL
1) Turn steering wheel so that vehicle's front tires are at straight-
ahead position.
2) Turn ignition switch to ªLOCKº position and remove key.
3) 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 figure).
4) Remove lower shaft assembly lower joint bolt and then remove
lower shaft assembly.
5) Remove shaft joint bolt (lower shaft assembly side) from shaft
joint and then remove shaft joint from lower shaft assembly.

8G-2 IMMOBILIZER CONTROL SYSTEM (IF EQUIPPED)
GENERAL DESCRIPTION
The immobilizer control system designed to prevent vehicle burglar consists of following components.
Engine control module (ECM) / Powertrain control module (PCM)
Immobilizer control module
Ignition key (with built-in transponder)
Coil antenna
Operation of this system is as follows.
(1) Each ignition key has its own code (Transponder code) stored in memory. When the ignition switch is turned
ON, Immobilizer Control Module tries to read the Transponder code through the coil antenna installed to the
steering lock assembly.
(2) Immobilizer Control Module compares the Transponder code read in (1) and that registered in Immobilizer Con-
trol Module and checks if they match.
(3) When it is confirmed that two Transponder codes match each other as described above, Immobilizer Control
Module and ECM / PCM check if ECM/Immobilizer Control Module codes registered in them respectively match.
(4) Only when it is confirmed that ECM/Immobilizer Control Module codes match, the engine starts running. If
Transponder codes in Step (2) or ECM/Immobilizer Control Module codes in Step (3) do not match, ECM / PCM
will stop operation of the injector and ignition of spark plug.
