10. Support inflator module and carefully connect the
SRS connector and horn lead, then install inflator
module.
NOTE: Pass the lead wire through the tabs on the plastic
cover (wire protector) of inflator to prevent lead wire from
being pinched.
11. Tighten fixing bolts to specified torque.

under the steering column.
15. Connect the battery ground cable.
System Inspection
Turn the ignition switch to the ªONº position and observe
the warning lamp. The lamp should flash 7 times. If the
lamp does not operate correctly, refer to
Restraints
section.

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
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.

Irregular and Premature Wear
480RS001
Irregular and/or premature wear has many causes.
Some of them are incorrect inflation pressures, lack of tire
rotation, poor driving habits or improper wheel alignment.
Incorrect inflation is common cause of tire premature
wear.NOTE: Due to their design, radial tires tend to wear faster
in the shoulder area, particularly on the front tires. This
makes regular rotation especially necessary. After
rotation, be sure to check wheel nut torque, and set tire
pressures.
