CLOCKSPRING
DESCRIPTION
The clockspring assembly is secured with two
screws to the multi-function switch mounting hous-
ing near the top of the steering column behind the
steering wheel (Fig. 13). The clockspring consists of a
flat, round molded plastic case with a stubby tail
that hangs below the steering column and contains
two connector receptacles that face toward the
instrument panel (Fig. 14). Within the plastic hous-ing is a spool-like molded plastic rotor with a large
exposed hub. The upper surface of the rotor hub has
a large center hole, two large flats, an index hole,
two short pigtail wires with connectors, and two con-
nector receptacles that face toward the steering
wheel.
The lower surface of the rotor hub has three pins,
two round and one oblong. These pins index the
clockspring to the turn signal cancel cam unit in the
multi-function switch mounting housing. Within the
plastic case and wound around the rotor spool is a
long ribbon-like tape that consists of several thin cop-
per wire leads sandwiched between two thin plastic
membranes. The outer end of the tape terminates at
the connector receptacles that face the instrument
panel, while the inner end of the tape terminates at
the pigtail wires and connector receptacles on the
hub of the clockspring rotor that face the steering
wheel.
Service replacement clocksprings are shipped pre-
centered and with a molded plastic locking pin
installed. The locking pin secures the centered clock-
spring rotor to the clockspring case during shipment
and handling, but must be removed from the clock-
spring after it and the multi-function switch mount-
ing housing are installed on the steering column.
(Refer to 8 - ELECTRICAL/RESTRAINTS/CLOCK-
SPRING - STANDARD PROCEDURE - CLOCK-
SPRING CENTERING).
The clockspring cannot be repaired. If the clock-
spring is faulty, damaged, or if the driver airbag has
been deployed, the clockspring must be replaced.

OPERATION
The clockspring is a mechanical electrical circuit
component that is used to provide continuous electri-
cal continuity between the fixed instrument panel
wire harness and the electrical components mounted
on or in the rotating steering wheel. On this model
the rotating electrical components include the driver
airbag, the horn switch, the speed control switches,
and the remote radio switches, if the vehicle is so
equipped. The clockspring case is positioned and
secured to the multi-function switch mounting hous-
ing on the upper steering column housing by two
screws. The two connector receptacles on the tail of
the fixed clockspring case connect the clockspring to
the vehicle electrical system through two take outs
with connectors from the instrument panel wire har-
ness. The clockspring rotor is movable and is keyed
to the hub of the steering wheel by two large flats
that are molded into the rotor hub. The three pins
(two round and one oblong) on the lower surface of
the clockspring rotor hub engage and index the clock-
spring rotor to the turn signal cancel cam. The turn
signal cancel cam is integral to the multi-function
switch mounting housing and is keyed to the upper
steering column shaft. Two short, yellow-sleeved pig-
tail wires on the upper surface of the clockspring
rotor connect the clockspring to the driver airbag,
while a steering wheel wire harness connects the two
connector receptacles on the upper surface of the
clockspring rotor to the horn switch, the two speed
control switches, and the remote radio switches on
vehicles that are so equipped.
Like the clockspring in a timepiece, the clockspring
tape has travel limits and can be damaged by being
wound too tightly during full stop-to-stop steering
wheel rotation. To prevent this from occurring, the
clockspring must be centered when it is installed on
the steering column. Centering the clockspring
indexes the clockspring tape to the movable steering
components so that the tape can operate within its
designed travel limits. However, if the clockspring is
removed from the steering column or if the steering
shaft is disconnected from the steering gear, the
clockspring spool can change position relative to the
movable steering components and must be re-cen-
tered following completion of the service or the tape
may be damaged. Service replacement clocksprings
are shipped pre-centered and with a locking pin
installed. This locking pin should not be removed
until the clockspring has been installed on the steer-
ing column. If the locking pin is removed before the
clockspring is installed on a steering column, the
clockspring centering procedure must be performed.
(Refer to 8 - ELECTRICAL/RESTRAINTS/CLOCK-
SPRING - STANDARD PROCEDURE - CLOCK-
SPRING CENTERING).
STANDARD PROCEDURE - CLOCKSPRING
CENTERING
The clockspring is designed to wind and unwind
when the steering wheel is rotated, but is only
designed to rotate the same number of turns (about
five complete rotations) as the steering wheel can be
turned from stop to stop. Centering the clockspring
indexes the clockspring tape to other steering compo-
nents so that it can operate within its designed
travel limits. The rotor of a centered clockspring can
be rotated two and one-half turns in either direction
from the centered position, without damaging the
clockspring tape.
However, if the clockspring is removed for service
or if the steering column is disconnected from the
steering gear, the clockspring tape can change posi-
tion relative to the other steering components. The
clockspring must then be re-centered following com-
pletion of such service or the clockspring tape may be
damaged. Service replacement clocksprings are
shipped pre-centered and with a molded plastic lock-
ing pin installed. This locking pin should not be
removed until the clockspring has been installed on
the steering column. If the locking pin is removed
before the clockspring is installed on a steering col-
umn, the clockspring centering procedure must be
performed.

(5) From the end of the clockwise travel, rotate the
rotor about two and one-half turns counterclockwise,
until the arrows on the clockspring rotor label and
the clockspring case are aligned. The uppermost pin
on the lower surface of the clockspring rotor should
now be the oblong pin.
(6) The clockspring is now centered. Secure the
clockspring rotor to the clockspring case to maintain
clockspring centering until it is reinstalled on the
steering column.
(7) The front wheels should still be in the straight-
ahead position. Reinstall the clockspring onto the
steering column. (Refer to 8 - ELECTRICAL/RE-
STRAINTS/CLOCKSPRING - INSTALLATION).
REMOVAL
The clockspring cannot be repaired. It must be
replaced if faulty or damaged, or if the driver airbag
has been deployed.

DRIVER AIRBAG
DESCRIPTION
The injection molded, thermoplastic driver airbag
protective trim cover is the most visible part of the
driver airbag (Fig. 18). The driver airbag is located in
the center of the steering wheel, where it is secured
with two screws to the two horizontal spokes of the
four-spoke steering wheel armature. A stamped, satin
polished emblem with the Jeeptlogo is applied to the
center of the trim cover. Concealed beneath the
driver airbag trim cover are the horn switch, the
folded airbag cushion, the airbag retainer or housing,
the airbag inflator, and the retainers that secure the
inflator to the airbag housing.
The airbag cushion, housing, and inflator are
secured within an integral receptacle molded into the
back of the trim cover. The driver airbag trim cover
has locking blocks molded into the back side of it
that engage a lip formed around the perimeter of the
airbag housing. Two stamped metal retainers then fitover the inflator mounting studs on the back of the
airbag housing and are engaged in slots within the
upper and lower trim cover locking blocks, securely
locking the cover into place.
The resistive membrane-type horn switch is
secured within a plastic tray that is inserted in a
pocket or pouch sewn onto the airbag cushion
retainer strap, between the trim cover and the folded
airbag cushion. The horn switch ground pigtail wire
has an eyelet terminal connector that is captured on
the upper right inflator mounting stud between the
inflator and the upper trim cover retainer. The horn
switch feed pigtail wire has a white, molded plastic
insulator that is secured by an integral retainer to a
mounting hole located in the upper trim cover
retainer near the upper left corner on the back of the
airbag housing, and is connected to the vehicle elec-
trical system through a take out and connector of the
steering wheel wire harness.
The airbag used in this model is a multistage, Next
Generation-type that complies with revised federal air-
bag standards to deploy with less force than those used
in some prior models. A radial deploying fabric airbag
cushion with tethers is used. The airbag inflator is a
dual-initiator, non-azide, pyrotechnic-type unit with
four mounting studs and is secured to the stamped
metal airbag housing using four hex nuts with washers.
Two keyed and color-coded connector receptacles on the
driver airbag inflator connect the two inflator initiators
to the vehicle electrical system through two yellow-
jacketed, two-wire pigtail harnesses of the clockspring.
The driver airbag cannot be repaired, and must be
replaced if deployed or in any way damaged. The driver
airbag trim cover and the horn switch are available
individually, and may be disassembled from the driver
airbag for service replacement.
