Calibration”.
• Regarding yaw rate / G sensor assembly removal/installation, confirm specified
torque and never use impact wrench to
avoid damage.
• When handling the yaw rate / G sensor assembly, be careful not to drop it or apply
an impact to it.
If an excessive impact was applied, never
attempt disassembly or repair but replace
it with a new one.

General Description
Steering Wheel and Column ConstructionS7RS0B6201001
This double tube type steering column has the following three important features in addition to the steering function:
• The column is energy absorbing, desig ned 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 op erations can be locked to inhibit theft of the vehicle.
To insure the energy absorbing action, it is important th at 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 or a sharp blow on the end of the
steering shaft, leaning on the assembly, or dropping the a ssembly 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 b ags. 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”.

Steering Wheel Removal and InstallationS7RS0B6206002
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 Installation
CAUTION!
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.
Tightening torque
Steering shaft nut (a): 33 N·m (3.3 kgf-m, 24.0 lb-
ft)
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 Installati on in Section 8B”.
6) Connect negative (–) battery cable.
7) Enable air bag system refe rring to “Enabling Air Bag
System in Section 8B”.

Steering Column Removal and InstallationS7RS0B6206006
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.

Removal
WARNING!
Never rest a steering column assembly on
the steering wheel with the air bag (inflator)
module face down and column vertical.
Otherwise, personal injury may result.

1) Disconnect negative (–) cable at battery.
2) Disable air bag system. Re fer to “Disabling Air Bag
System in Section 8B”.
3) Remove steering wheel and contact coil cable assembly referring to “S teering Wheel Removal and
Installation” and “Contact Coil Cable Assembly
Removal and Installation”.
4) Detach lighting switch and wiper switch from steering column.
5) Remove immobilizer cont rol module from steering
column, referring to “Immo bilizer Control Module
(ICM) Removal and Installation in Section 10C”.
6) Remove steering column hole cover.
7) Remove steering joint cover.
8) Make alignment marks (4) on lower shaft (1) and shaft joint of steering column (2) and lower shaft (1)
and pinion shaft (3) for a guide during reinstallation.
9) Remove lower shaf t joint bolts (5).
10) Remove steering lower shaft (1).
11) Remove steering column mounting nuts (1).
12) Remove steering column from vehicle.
