W CAUTION:
When fasteners are removed, always reinstall them at the same location from which they were removed.
If a fastener needs to be replaced, use the correct part number fastener for that application. If the correct
part
number fastener is not available, a fastener of equal size and strength (or stronger) may be used.
Fasteners
that are not reused, and those requiring thread locking compound, will be called out. The correct
torque value must be used when installing fasteners that require it. If the above conditions are not
followed, parts or system damage could result.

GENERAL DESCRIPTION
W WARNING
TO AVOID DEPLOYMENT WHEN TROUBLE
SHOOTING
THE SRS SYSTEM, DO NOT USE
ELECTRICAL TEST EQUIPMENT, SUCH AS
BATTERY-POWERED OR A/C-POWERED VOLT
METER, OHMMETER, ETC., OR ANY TYPE OF
ELECTRICAL EQUIPMENT OTHER THAN SPE
CIFIED IN THIS MANUAL. DO NOT USE A NON
POWERED
PROBE-TYPE TESTER.
INSTRUCTION IN THIS MANUAL MUST BE
FOLLOWED CAREFULLY, OTHERWISE PER
SONAL INJURY MAY RESULT.
This steering
wheel and column repair section covers
the Supplemental Restraint System (SRS) steering
column. The following repair procedures are specific
to SRS Components. When servicing a vehicle
equipped with Supplemental Restraint System, pay
close attention to all WARNINGS and CAUTIONS.
For detailed explanation about SRS, refer to Section
9J "SUPPLEMENTAL
RESTRAINT SYSTEM (SRS)" of
this manual.
The steering column has three important features in
addition to the steering function:
1. The column is energy absorbing, designed to
compress in a front-end collision to minimize the
possibility of injury to the driver of the vehicle.
2. The ignition switch and lock are mounted con
veniently on the column.
3. With the column mounted lock, the ignition and
steering operation can be
locked to prevent theft
of the vehicle.
The column may be disassembled and reassembled.
To insure the energy absorbing action, it is important
that the specified screws, bolts and nuts be used only
as designated and that they are tightened to the
specified torque.
When the column is removed from the vehicle, a
sharp
blow on the end of steering shaft or shift lever,
leaning
on the column assembly, or dropping the
assembly could shear or loosen the fasteners that
maintain column rigidity.

ON-VEHICLE SERVICE
SPECIAL SERVICE PRECAUTIONS
\f CAUTION:
Safe
handling of Inflator modules requires fol
lowing the procedures described below for both
live and deployed modules.
\f WARNING
SAFETY PRECAUTIONS MUST BE FOLLOWED
WHEN HANDLING A DEPLOYED INFLATOR
MODULE (AIR
BAG). AFTER DEPLOYMENT, THE
INFLATOR MODULE (AIR BAG) SURFACE MAY
CONTAIN A SMALL AMOUNT OF SODIUM
HYDROXIDE,
A BY-PRODUCT OF THE DEPLOY
MENT REACTION, THAT IS IRRITATING TO THE
SKIN AND EYES. MOST OF THE POWDER ON
THE INFLATOR MODULE (AIR BAG) IS HARM
LESS. AS A PRECAUTION, WEAR GLOVES AND
SAFETY GLASSES WHEN HANDLING A DE
PLOYED INFLATOR MODULE (AIR BAG), AND
WASH YOUR HANDS WITH MILD SOAP AND
WATER AFTERWARDS.
WHEN CARRYING A
LIVE INFLATOR MODULE
(AIR
BAG), MAKE SURE THE BAG AND TRIM
COVER ARE POINTED AWAY FROM YOU.
NEVER CARRY AN INFLATOR MODULE (AIR
BAG) BY THE WIRES OR CONNECTOR ON THE
UNDERSIDE OF MODULE. IN THE CASE OF AN
ACCIDENTAL DEPLOYMENT,
THE BAG WILL
THEN DEPLOY WITH MINIMAL CHANCE OF
INJURY. WHEN PLACING A LIVE INFLATOR
MODULE (AIR
BAG) ON A BENCH OR OTHER
SURFACE, ALWAYS FACE THE BAG AND TRIM
COVER UP, AWAY FROM THE SURFACE.
NEVER
REST A STEERING COLUMN AS
SEMBLY ON
THE STEERING WHEEL WITH THE
INFLATOR MODULE (AIR BAG) FACE DOWN
AND COLUMN VERTICAL. THIS IS NECESSARY
SO THAT A FREE SPACE IS PROVIDED TO AL
LOWTHE INFLATOR MODULE (AIR BAG) TO EX
PAND
IN THE UNLIKELY EVENT OF ACCI
DENTAL DEPLOYMENT.
OTHERWISE, PERSO
NAL INJURY COULD RESULT.
For detailed explanation
about SRS, refer to Section
9J "SUPPLEMENTAL
RESTRAINT SYSTEM (SRS)" of
this manual.
SRS CONNECTORS
w CAUTION:
Double-lock type yellow color connectors are
used
for supplemental restraint system-air bag
circuit.
When removing the cable harness, disconnect
the connector by unlocking at two places, outside
CD and inside®. In such a case, do not pull the
cables. Otherwise, cable disconnection may
occur.
When connect the double lock type SRS
connector, insert the connector completely and
lock at outside. Imperfect locking
may cause
malfunction of SRS circuit. (Fig. 3F4-1)

THE INFLATOR MODULE SHOULD ALWAYS BE
CARRIED WITH THE URETHANE COVER AWAY
FROM YOUR BODY AND SHOULD ALWAYS BE
LAID ON A FLAT SURFACE WITH THE URE
THANE SIDE UP. THIS IS NECESSARY BE
CAUSE A FREE SPACE IS PROVIDED TO ALLOW

The
Inflator module consists of a cover, air bag,
inflator, and retainer.
Inspect the Inflator module
mainly for the following:
1) Check for holes, cracks, severe blemishes and
deformation on the cover.
2) Check that the retainer is not deformed.
3) Check for defects such as damage and breakage in
the lead
wire ofthe squib.
If an abnormality is found as the result of the in
spection, replace the
Inflator module with a new one.
l·u·IINSTALLATION
3. Inflator module
2. Module connector
• Support the module and carefully connectthe
module connector.
NOTE:
Pass the lead wire through the tabs on the plastic
cover (wire protector)
of inflator to prevent lead
wire
from being pinched.
1. Fixing bolt
• Secure the module with one bolt to relieve
weight on the connector wire.
• Tighten bolts to specified sequence as figure
(Fig. 3F4-6).
Torque
N·m(lb·in.) 8 (69)
• Connect the yellow 3way SRS connector
located under the steering column.
• Connect the battery .. _. terminal cable.
• Set ignition to "ON" while watching warning light.
Light should flash 7 times and then go off.
If lamp
does
not operate correctly, refer to Section 9J.

STEERING WHEEL REPLACEMENT
\f' 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
slide block which maintains column rigidity.
Leaning on the column assembly could cause the
jacket
to bend or deform. Any of the above
damage could
impair the column's collapsible
design. If it is necessary to remove the steering
wheel, use
only the specified steering wheel
puller.
Under no conditions should the end of the
shaft be hammered upon,
as hammering could
loosen
slide block which maintains column
rigidity.
