Service Precaution
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.CAUTION: Always use the correct fastener in the
proper location. When you replace a fastener, use
ONLY the exact part number for that application.
ISUZU will call out those fasteners that require a
replacement after removal. ISUZU will also call out
the fasteners that require thread lockers or thread
sealant. UNLESS OTHERWISE SPECIFIED, do not
use supplemental coatings (Paints, greases, or
other corrosion inhibitors) on threaded fasteners
or fasteners joint interfaces. Generally, such
coatings adversely affect the fastener torque and
the joint clamping force, and may damage the
fastener. When you install fasteners, use the
correct tightening sequence and specification.
Following these instructions can help you avoid
damage to parts and systems.

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 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
conveniently 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.
WARNING
THIS VEHICLE HAS A SUPPLEMENTAL RE-
STRAINT 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 INFORM ATION.
FAILURE TO FOLLOW WARNINGS COULD RE-
SULT IN POSSIBLE AIR BAG DEPLOYMENT,
PERSONAL INJURY, OR OTHERWISE UN-
NEEDED SRS SYSTEM REPAIRS.
SAFE HANDLING OF INFLATOR MODULES
REQUIRES FOLLOWING THE PROCEDURES
DESCRIBED BELOW FOR BOTH LIVE AND
DEPLOYED MODULES.
SAFETY PRECAUTIONS MUST BE FOLLOWEDWHEN HANDLING A DEPLOYED AIR BAG AS-
SEMBLY (AIR BAG). AFTER DEPLOYMENT,
THE AIR BAG ASSEMBLY (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 AIR BAG ASSEMBLY (AIR BAG) IS HARM-
LESS. 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 DEPLOY-
MENT, 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. OTHER-
WISE, PERSONAL INJURY COULD RESULT.
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 SPECI-
FIED IN THIS MANUAL. DO NOT USE A NON-
POWERED PROBE-TYPE TESTER.
INSTRUCTIONS IN THIS MANUAL MUST BE
FOLLOWED CAREFULLY, OTHERWISE PER-
SONAL INJURY MAY RESULT. 2A – 52 SUPPLEMENTAL RESTRAINT SYSTEM STEERING WHEEL & COLUMN
GENERAL DESCRIPTION

SUPPLEMENTAL RESTRAINT SYSTEM STEERING WHEEL & COLUMN 2A – 61
1. Front Console Assembly
1) Remove the transmission (for M/T) and transfer
control lever knob.
2) Disconnect the wiring harness connectors.
2. Lower Cluster Assembly
3. Steering Lower Cover
Remove the engine hood opening lever.
4. Inflator Module
1) Loosen the inflator module fixing bolt from
behind the steering wheel assembly using a
TORX
driver or equivalent until the inflator
module can be released from steering assembly.
2) Disconnect the yellow 2way SRS connector
located behind the inflator module.
WARNING
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 URETHANE SIDE UP. THIS IS NECESSARY
BECAUSE A FREE SPACE IS PROVIDED TO ALLOW THE
AIR CUSHION TO EXPAND IN THE UNLIKELY EVENT OF A
ACCIDENTAL DEPLOYMENT. OTHERWISE, PERSONAL
INJURY MAY RESULT.
5. Steering Wheel
Apply a setting mark across the steering wheel and
shaft so parts can be reassembled in their original
position.

Use special tool. Remove the steering wheel.
Move the tires to the straight ahead position before
removing the steering wheel.
Steering wheel remover: 5-8840-0016-0 (J-29752)
CAUTION:
Never apply force to the steering wheel in direction of the
shaft by using a hammer or other impact tools in an
attempt to remove the steering wheel. The steering shaft
is designed as an energy absorbing unit.
6. Steering Column Cover
7. Combination Switch and SRS Coil Assembly
1) Disconnect the wiring harness connectors
located under the steering column.
2) Remove the combination switch assembly with
SRS coil.
NOTE:
The SRS coil is a part of the combination switch
assembly, which can not be replaced separately.
Therefore, be sure not to remove the SRS coil from
the combination switch assembly.

7. Combination Switch and SRS Coil Assembly
1) After installation of combination switch
assembly, connect the combination switch
wiring harness connector and the SRS 2way
connector located under the steering column.
2) Turn the SRS coil counterclockwise to full, return
about 3 turns and align the neutral mark.
CAUTION:
When turning the SRS coil counterclockwise to full, stop
turning if resistance is felt. Forced further turning may
damage to the cable in the SRS coil.

5. Steering Wheel
Align the setting marks made when removing.
CAUTION:
Never apply force to the steering wheel in direction of the
shaft by using a hammer or other impact tools in an
attempt to remove the steering wheel. The steering shaft
is designed as an energy absorbing unit.
Tighten the steering wheel fixing nut to the specified
torque.

4. Inflator Module
1) Support the module and carefully connect the
module connector.
CAUTION:
·Never use the air bag assembly from another vehicle.
Use only the air bag assembly for "UBS".
·When replace the inflator module, use only same parts
number assembly. If different parts number assembly is
installed, the air bag system can not function correctly
because it has different characteristic.
NOTE:
Pass the lead wire through the tabs on the plastic
cover (wire protector) of inflator to prevent lead wire
from being pinched.
2) Secure the module with one bolt to relieve
weight on the connector wire.
3) Tighten bolts to specified sequence as figure.
Inflator Module Bolt Torque Nám (kgám/lbáin)

3. Steering Lower Cover
Install the engine hood opening lever.
2. Lower Cluster Assembly
1. Front Console Assembly
1) Install the transmission (for M/T) and transfer
control lever knob.
2) Install the wiring harness connectors.
Connect the battery ground cable.
Turn the 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.
