SUPPLEMENTAL RESTRAINT SYSTEM (SRS) STEERING WHEEL & COLUMN 3F4-11
Fig. 3F4-25
WCAUTION:
Never apply force to the steering wheel in
direction
of the shaft by using a hammer or other
impacttools in an attempt to remove the steering
wheel. The steering shaft is designed as an
energy absorbing unit.
\f 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, PERSONALINJURY MAY RESULT
(FIG.3F4-26).

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.

EJREMOVAL
Preparation: • Turn the steering wheel so that the
vehicle's
wheels are pointing straight
ahead.
• 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.
wcAUTION:
The wheel of the vehicle must be straight ahead
and the steering
column in the "LOCK• position
before disconnecting the steering
column from
the steering gear.
Failure to do so will cause the SRS coil assembly
to become uncentered which will cause damage
to the SRS coil assembly.
1. Front console assembly
• Disconnect the transmission (for MfT) and
transfer
control lever knob.
• Disconnect the wiring harness connectors.
2. Steering lower cover
• Remove the engine hood opening lever.
3. Driver knee bolster (reinforcement)
4. Inflator module (Fig.3F4-32)
• 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.
•
Disconnect the yellow 2way SRS connector
located behind the inflator module.

\V WARNING
THE INFLATOR MODULE SHOULD ALWAYS BE
CARRIED WITH THE URETHANE COVER AWAY
FROM YOUR BODY AND SHOULD ALWAYS BE

5. Steering wheel
• Apply a setting mark across the steering
wheel and shaft so parts can be reassembled
in their original position (Fig. 3F4-34)
• Use special tool. Remove the steering wheel.
move the tires to the straight ahead position
before removing the steering
wheel (Fig. 3F4-

\fl CAUTION:
VI When fasteners are removed, always reinstall them at the same location from which they were removed. If a
fastener needs
to be replaced, use the correct part number fastener for that application. If the correct part
number fastener is
not available, a fastener of equal size and strength (or stronger) may be used. Fasteners
that are
not reused, and those requiring thread locking compound, will be called out. The correct torque
values must be used when installing fasteners that require torque. If the above conditions are not followed, •
parts or system damage could result.
