POWER-ASSISTED STEERING SYSTEM 3B-27
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. W hen servicing a vehicle equipped
with Supplemental Restraint System, pay close attention
to all W ARNINGS 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 UNNECESSARY SRS SYSTEM
REPAIRS.
SAFE HANDLING OF INFLATOR MODULES
REQUIRES THE PROCEDURES DESCRIBED
BELOW TO BE FOLLOWED 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 DEPLO
YED 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
A
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 the supplemental restraint system-air bag
circuit.
When removing the cable harness, do not pull the
cables. Otherwise, cable disconnection may occur.
When connecting the SRS connector, insert the
connector completely. Imperfect locking may cause
malfunction of the SRS circuit.

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/GM will indicate those fasteners that require
replacement after removal. ISUZU/GM will also
indicate the fasteners that require thread lockers o
r
thread sealant. UNLESS OTHERWISE SPECIFIED,
do not use supplemental coatings (paints, greases,
or other corrosion inhibitors) on threaded fasteners
or fastener 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 specifications.
Following these instructions can help you avoid
damage to parts and systems.
