Disposal
For disposal, refer to “Precautions on Disposal of Air Bag and Seat Belt Pretensioner in Section 8B”.
General Description
Steering Wheel and Column ConstructionS6RW0D6201001
This double tube type steering column has the following three important features in addition to the steering function:
• The column is energy absorbing, designed to compress in a front-end collision.
• The ignition switch and lock are mounted conveniently on this column.
• With the column mounted lock, the ignition and steering operations can be locked to inhibit theft of the vehicle.
To insure the energy absorbing action, it is important that only the specified screws, bolts and nuts be used as
designated, and that they are tightened to the specified torque. When the column assembly is removed from the
vehicle, special care must be taken in handling it. Use of a steering wheel puller other than the recommended puller in
this manual or a sharp blow on the end of the steering shaft, leaning on the assembly, or dropping the assembly could
shear the plastic shear pins which maintain column length and position.
The driver air bag (inflator) module is one of the supplemental restraint (air bag) system components and is mounted
to the center of the steering wheel. During certain frontal crashes, the air bag system supplements the restraint of the
driver’s and passenger’s seat belts by deploying the air bags. The air bag (inflator) module should be handled with
care to prevent accidental deployment. When servicing, be sure to observe “Precautions on Service and Diagnosis of
Air Bag System in Section 8B”.

Downloaded from www.Manualslib.com manuals search engine 6B-5 Steering Wheel and Column:
4) Connect horn connector and audio control switch
connector, if necessary.
5) Install driver air bag (inflator) module to steering
wheel. Refer to “Driver Air Bag (Inflator) Module
Removal and Installation in Section 8B”.
6) Connect negative (–) cable to battery.
7) Enable air bag system referring to “Enabling Air Bag
System in Section 8B”.
Contact Coil Cable Assembly Removal and
Installation
S6RW0D6206003
CAUTION!
Do not turn contact coil more than allowable
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”.
4) Remove steering column hole cover.
5) Remove steering column lower cover (2) and upper
cover (1).6) Remove contact coil cable assembly (1) from
steering column.
Installation
1) Check to make sure that vehicle’s front tires are set
at straight-ahead position and then ignition switch is
at LOCK position.
2) Install contact coil cable assembly to steering
column securely.
NOTE
New contact coil cable assembly is supplied
with contact coil set and held at its center
position with a lock pin (1). Remove this lock
pin after installing contact coil cable
assembly to steering column.

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.
