Supplemental Restraint System Steering Wheel & Column
Service Precaution
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
Restraints
section.
WARNING: THIS VEHICLE HAS A SUPPLEMENTAL
RESTRAINT SYSTEM (SRS). REFER TO THE SRS
COMPONENT AND WIRING LOCATION VIEW IN
ORDER TO DETERMINE WHETHER YOU ARE
PERFORMING SERVICE ON OR NEAR THE SRS
COMPONENTS OR THE SRS WIRING. WHEN YOU
ARE PERFORMING SERVICE ON OR NEAR THE SRS
COMPONENTS OR THE SRS WIRING, REFER TO
THE SRS SERVICE INFORMATION. FAILURE TO
FOLLOW WARNINGS COULD RESULT IN POSSIBLE
AIR BAG DEPLOYMENT, PERSONAL INJURY, OR
OTHERWISE UNNEEDED SRS SYSTEM REPAIRS.
SAFE HANDLING OF INFLATOR MODULES
REQUIRES FOLLOWING THE PROCEDURES
DESCRIBED BELOW FOR BOTH LIVE AND
DEPLOYED MODULES.
SAFETY PRECAUTIONS MUST BE FOLLOWED
WHEN HANDLING A DEPLOYED AIR BAG
ASSEMBLY (AIR BAG). AFTER DEPLOYMENT, THE
AIR BAG ASSEMBLY (AIR BAG) SURFACE MAY
CONTAIN A SMALL AMOUNT OF SODIUM
HYDROXIDE, A BY-PRODUCT OF THE
DEPLOYMENT REACTION, THAT IS IRRITATING TO
THE SKIN AND EYES. MOST OF THE POWDER ON
THE AIR BAG ASSEMBLY (AIR BAG) IS HARMLESS.
AS A PRECAUTION, WEAR GLOVES AND SAFETY
GLASSES WHEN HANDLING A DEPLOYED AIR BAG
ASSEMBLY, AND WASH YOUR HANDS WITH MILD
SOAP AND WATER AFTERWARDS.WHEN CARRYING A LIVE AIR BAG ASSEMBLY,
MAKE SURE THE BAG AND TRIM COVER ARE
POINTED AWAY FROM YOU. NEVER CARRY AN AIR
BAG ASSEMBLY 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 AIR BAG ASSEMBLY ON A
BENCH OR OTHER SURFACE, ALWAYS FACE THE
BAG AND TRIM COVER UP, AWAY FROM THE
SURFACE.
NEVER REST A STEERING COLUMN ASSEMBLY ON
THE STEERING WHEEL WITH THE AIR BAG
ASSEMBLY FACE DOWN AND COLUMN VERTICAL.
THIS IS NECESSARY SO THAT A FREE SPACE IS
PROVIDED TO ALLOW THE AIR BAG ASSEMBLY TO
EXPAND IN THE UNLIKELY EVENT OF ACCIDENTAL
DEPLOYMENT. OTHERWISE, PERSONAL INJURY
COULD RESULT.
TO AVOID DEPLOYMENT WHEN
TROUBLESHOOTING 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
SPECIFIED IN THIS MANUAL. DO NOT USE A
NON-POWERED PROBE-TYPE TESTER.
INSTRUCTIONS IN THIS MANUAL MUST BE
FOLLOWED CAREFULLY, OTHERWISE PERSONAL
INJURY MAY RESULT.
SRS Connectors
CAUTION: The special 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 (1)
and inside (2). Do not pull the wires or disconnection
may occur.
When connecting the double lock type SRS connec-
tor, insert the connector completely then lock the
connector. Imperfect locking may cause the SRS cir-
cuit to malfunction.

Inspection and Repair
WARNING: T H E I N F L AT O R M O D U L E S H O U L D
ALWAYS BE CARRIED WITH THE TRIM COVER
AWAY FROM YOUR BODY AND SHOULD ALWAYS
BE LAID ON A FLAT SURFACE WITH THE
URETHANE SIDE UP. THIS IS NECESSARY
BECAUSE FREE SPACE IS PROVIDED TO ALLOW
THE AIR CUSHION TO EXPAND IN THE UNLIKELY
EVENT OF ACCIDENTAL DEPLOYMENT.
OTHERWISE, PERSONAL INJURY MAY RESULT .
827RW072
The inflator module consists of a cover, air bag, inflator,
and retainer. Inspect the inflator module mainly for the
following:

Check for holes, cracks, severe blemishes and
deformation on the cover.

Check that the retainer is not deformed.

Check for defects such as damage and breakage in
the lead wire for the igniter.
Replace the inflator module if a defect is found during
inspection.
Installation
1. Install inflator module.
2. Support the module and carefully connect the module
connector and horn lead.
NOTE: Pass the lead wire through the tabs on the plastic
cover (wire protector) of inflator to prevent lead wire from
being pinched.
3. Tighten bolts to specified torque.
Torque: 9 N´m (78 lb in)
4. Connect the yellow 2-way SRS connector located
under the steering column.
5. Connect the battery ª±º terminal cable.
6. Set ignition to ªONº while watching warning light.
Light should flash 7 times and then go off. If lamp
does not operate correctly, refer to
Restraints section.

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 the
slide block which maintains column rigidity.Removal
1. Turn the steering wheel so that the vehicle's wheels
are pointing straight ahead.
2. Turn the ignition switch to ªLOCKº.
3. Disconnect the battery ground cable, and wait at least
5 minutes.
4. Disconnect the yellow 2-way SRS connector located
under the steering column.
