GENERAL INFORMATION 0A-3
Servicing and handling
WARNING:
Many of service procedures require disconnection of
“AIR BAG” fuse and all air bag (inflator) module(s) from
initiator circuit to avoid an accidental deployment.
Driver and Passenger Air Bag (Inflator) Modules
 For handling and storage of a live air bag (inflator)
module, select a place where the ambient temperature
below 65°C (150°F), without high humidity and away
from electric noise.
 When carrying a live air bag (inflator) module, make
sure the bag opening is pointed away from you. In
case of an accidental deployment, the bag will then
deploy with minimal chance of injury. Never carry the
air bag (inflator) module by the wires or connector on
the underside of the module. When placing a live air
bag (inflator) module on a bench or other surface,
always face the bag up, away from the surface. As the
live passenger air bag (inflator) module must be placed
with its bag (trim cover) facing up, place it on the work-
bench with a slit or use the workbench vise to hold it
securely at its lower mounting bracket. This is neces-
sary so that a free space is provided to allow the air
bag to expand in the unlikely event of accidental
deployment. Otherwise, personal injury may result.
 Never dispose of live (undeployed) air bag (inflator)
modules (driver and passenger). If disposal is neces-
sary, be sure to deploy them according to deployment
procedures described in SECTION 10B before dis-
posal.
 The air bag (inflator) module immediately after deploy-
ment is very hot. Wait for at least half an hour to cool it
off before proceeding the work.
 After an air bag (inflator) module has been deployed,
the surface of the air bag may contain a powdery resi-
due. This powder consists primarily of cornstarch
(used to lubricate the bag as it inflates) and by-prod-
ucts of the chemical reaction. As with many service
procedures, gloves and safety glasses should be
worn.
[A] : ALWAYS CARRY AIR BAG (INFLATOR) MODULE WITH TRIM COVER (AIR
BAG OPENING) AWAY FROM BODY.
[B] : ALWAYS PLACE AIR BAG (INFLATOR) MODULE ON WORKBENCH WITH
TRIM COVER (AIR BAG OPENING) UP, AWAY FROM LOOSE OBJECTS.
1. Slit on workbench
2. Lower mounting bracket
3. Workbench vise

0A-4 GENERAL INFORMATION
WARNING:
SDM
 During service procedures, be very careful when handling a Sensing and Diagnostic Module (SDM).
Never strike or jar the SDM.
Never power up the air bag system when the SDM is not rigidly attached to the vehicle. All SDM and
mounting bracket fasteners must be carefully torqued and the arrow must be pointing toward the
front of the vehicle to ensure proper operation of the air bag system.
The SDM could be activated when powered while not rigidly attached to the vehicle which could
cause deployment and result in personal injury.
WARNING:
Driver and Passenger Seat Belt Pretensioners
 For handling and storage of a live seat belt preten-
sioner, select a place where the ambient temperature
below 65°C (150°F), without high humidity and away
from electric noise.
 Never carry seat belt pretensioner by wire or connec-
tor of pretensioner. When placing a live seat belt pre-
tensioner on the workbench or some place like that, be
sure not to lay it with its exhaust hole (1) provided side
facing down. It is also prohibited to put something on
its face with an exhaust hole or to put a seat belt pre-
tensioner on top of another. Otherwise, personal injury
may result.
 Never dispose of live (inactivated) seat belt pretension-
ers (drive and passenger). If disposal is necessary, be
sure to activate them according to activation proce-
dures described in SECTION 10B before disposal.
 The seat belt pretensioner immediately after activation
is very hot. Wait for at least half an hour to cool it off
before proceeding the work.
 With many service procedures, gloves and safety
glasses should be worn to prevent any possible irrita-
tion of the skin or eyes.

3C1-4 AIR BAG STEERING WHEEL AND COLUMN
Steering Column
REMOVAL
1) Disconnect negative (–) cable at battery.
2) Disable air bag system. Refer to “DISABLING AIR BAG SYSTEM” under “SERVICE PRECAUTIONS” in
Section 10B.
3) Remove steering wheel and contact coil and combination switch assembly, if necessary. Refer to “STEER-
ING WHEEL” and “CONTACT COIL AND COMBINATION SWITCH ASSEMBLY” in this section.
Perform the following procedure if not removing steering wheel and/or combination switch.
a) Turn steering wheel so that vehicle’s front tires are at straight-ahead position.
b) Turn ignition switch to “LOCK” position and remove key.
4) Remove steering column hole cover (1).
5) Disconnect all connectors for the following parts.
Contact coil and combination switch
Ignition switch CAUTION:
Once the steering column is removed from the vehicle, the column is extremely susceptible to dam-
age.
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 collapsible design.
When loosening steering column mounting bolts and nuts, make sure that steering column assembly
and steering upper shaft assembly have been separated. Loosening them with steering column
assembly and steering upper shaft assembly assembled could cause damage to upper joint and
mounting bracket in steering upper shaft assembly.
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 steer-
ing wheel installed on steering column.
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.
CAUTION:
Never turn steering wheel while steering column with steering wheel is removed. Turning steering
wheel more than about two and a half turns will break contact coil.

3C1-6 AIR BAG STEERING WHEEL AND COLUMN
3) Install steering column assembly (1) with contacting upper
side of lower bracket slits to mounting bolts. Tighten steering
column lower mounting nuts (3) first and then upper mount-
ing bolts (2) to specified torque.
Tightening torque

25 N·m (2.5 kg-m, 18.0 lb-ft)
4) Align cutting point “A” of steering column assembly (1) with
bolt hole “B” of steering upper shaft upper joint as shown in
the figure. Then connect steering upper shaft upper joint.
5) Install steering upper shaft upper joint bolt (2) and nut (1).
Tighten steering upper shaft upper joint nut (1) to specified
torque.
Tightening torque
Steering upper shaft upper joint nut (a) :
23 N·m (2.3 kg-m, 17.0 lb-ft)
6) If contact coil and combination switch assembly is removed,
install it, referring to “CONTACT COIL AND COMBINATION
SWITCH ASSEMBLY” in this section.
