E) REMOVAL
Preparation: • Turn the steering wheel so that the
vehicle's wheels are pointing straight
ahead.
W CAUTION: •
Turn the ignition switch to "LOCK".
•
Disconnect the battery "-" terminal
cable, and wait at least 5 minutes.
• Disconnect the yellow 3way SRS
connector located under the steering
column.
The wheels ofthe vehicle must be straight ahead
and
the steering column in the "LOCK" position
before disconnecting the steering wheel. Failure
to do so will cause the coil assembly to become
uncentered
which will cause damage to the coil
assembly.
1.
Front console assembly
•
Remove the transmission (for M{f) and
transfer control lever knob.
• Disconnect the wiring harness connectors.
2. Steering lower cover
• Remove the engine hood opening lever.
3. SRS module (Fig.3F4-14 and 15)
• Loosen the inflator module fixing bolt from behind
the steering
wheel assembly using a TORxe driver
or
equivalent until the inflator module can be
released from steering assembly.
•
Disconnect the yellow 2way SRS connector
located behind the inflator module.

W 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 URE­
THANE SIDE UP. THIS IS NECESSARY BE­
CAUSE A FREE SPACE IS PROVIDED TO ALLOW
THE AIR CUSHION TO EXPAND IN THE UN­
LIKELY EVENT
OF ACCIDENTAL DEPLOYMENT.
OTHERWISE, PERSONAL INJURY MAY RESULT
(FIG. 3F4-16).

4. Steering wheel
•
Apply a setting mark across the steering
wheel and shaft so parts can be reassembled
in
their original position (Fig. 3F4-17)
• Use special tool. Remove the steering wheel.
Move the tires
to the straight ahead position
before removing the steering wheel (Fig.
3F4-
18).

\V 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.
5. Steering column cover
6. Combination switch and SRS coil assembly
•
Disconnect the wiring harness connectors
located under the steering column.
• Remove the combination switch assembly
with SRS coil (Fig. 3F4-19).
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.

B INSTALLATION
6. Combination switch and SRS coil assembly
•
After installation of combination switch as­
sembly, connect the combination switch
wiring harness connector and the SRS 3way
connector located under the steering column.
•
Turn the SRS coil clockwise to full, return
about 3
turns and align the neutral mark
(Fig.3F4-20).
Alignment mark
Fig. 3F4-20
WcAUTION:
When turning the SRS coil clockwise to full, stop
turning if resistance is felt. Forced further turning
may damage to the cable in the SRS coil.
5. Steering column cover
• When installing the steering column cover, be
sure
to wire (through each harness) as
illustrated so that the harnesses starter
switch,
combination switch and SRS coil may
not catch wiring (Fig. 3F4-21 ).

3. SRS module
• Support the module and carefully connect the
module connector.
NOTE:
Pass the lead wire through the tabs on the plastic
cover (wire protector) of inflator to prevent lead
wire from being pinched.
• Secure the module with one bolt to relieve
weight on the connector wire.
• Tighten bolts to specified sequence as figure
(Fig. 3F4-22).
Torque
N·m (lb·in) 8 (69)
2. Steering lower cover
• Install the engine hood opening lever.
1. Front console assembly
• Install
the transmission (for MfT) and transfer
control lever knob.
• Install the wiring harness connectors.
• Connect the battery "-"terminal cable.
• Set
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.
