Inspection
If the abnormal conditions are found through inspection,
replace the steering column assembly.

Column Capsule
Check capsules on steering column bracket assembly;
all must be securely seated in bracket slots and
checked for any loose conditions when pushed or pulled
by hand.
431RW030

POWER-ASSISTED STEERING SYSTEM 3B-59

Check clearance between capsule and bracket. If must
be within 1mm (0.039 in).

Column Universal Joint (between the
power steering unit and the steering shaft)
If the resistance is felt when checked by rotate the joint,
replace the lower second steering shaft.

Shaft Universal Joint (between the lower
second steering shaft and the second
steering shaft)
If the resistance is felt when checked by rotate the joint,
replace the second steering shaft assembly.

9. Turn the SRS coil counter clockwise to full, return
about 3 turns and align the neutral mark. (with SRS
air bag)
CAUTION: When turning the SRS coil counte
r
clockwise to full, stop turning if resistance is felt.
Forced further turning may damage to the cable in
the SRS coil.

10. When installing the steering column cover, be sure to
route each wire harness as illustrated so that the
harnesses do not catch any moving parts.

11. Install steering wheel and align the setting marks
made when removing.
Refer to the adjustment method in case a mark is
not attached in this section.
NOTE: Confirm SRS and Horn harness connector is
fixed by the steering wheel.
RTW33BSH000601

CAUTION: Never apply force to the steering wheel in
direction of the shaft by using a hammer or othe
r
impact tools in an attempt to remove the steering
wheel. The steering shaft is designed as an energy
absorbing unit.
12. Tighten the steering wheel fixing nut to the specified
torque.
Torque: 31 - 39 N




m (3.2 – 4.0 kg




m/23 - 29 lb ft)
13. Support the module and carefully connect the
module connector and horn lead, then install inflato
r
module.
NOTE: Pass the lead wire through the tabs on the
plastic cover (wire protector) of inflator to prevent lead
wire from being pinched.
14. Tighten bolts to specified torque.
Torque: 2 - 4 N




m (0.2 – 0.4 kg




m/17 - 35 lb in)
15. Install driver knee bolster (reinforcement).
16. Install instrument panel lower cover.

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, REFE
R
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, o
r
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.
