vide access to the case mounting screws. The lower
side of the rotor hub also serves as an integral
molded plastic turn signal cancel cam.
A single connector receptacle on the upper surface
of the rotor has pigtail wires that connect to the horn
switch and the driver airbag on the steering wheel,
while a single connector receptacle on the lower sur-
face of the case has pigtail wires that connect the
clockspring to the vehicle wire harness on the steer-
ing column. Within the plastic case and wound
around the rotor spool is a long ribbon-like tape that
consists of several thin copper wire leads sandwiched
between two thin plastic membranes. The outer end
of the tape terminates at the connector receptacle
that faces the steering column, while the inner end of
the tape terminates at the connector receptacle on
the hub of the clockspring rotor that faces the steer-
ing wheel.
Service replacement clocksprings are shipped pre-
centered and with the mounting screws backed out
from the case far enough to engage the access holes
in the upper surface of the rotor. The mounting
screws secure the centered clockspring rotor to the
clockspring case during shipment, but allow free
rotation of the rotor once the clockspring is properly
installed on the steering column. (Refer to 8 - ELEC-
TRICAL/RESTRAINTS/CLOCKSPRING - STAN-
DARD PROCEDURE - CLOCKSPRING
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 vehicle 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 and
the horn switch. The clockspring case is positioned
and secured to the multi-function switch housing
near the top of the steering column. The connector
receptacle on the underside of the fixed clockspring
case connects the clockspring to the vehicle electrical
system through two take outs with connectors from
the vehicle wire harness.
The clockspring rotor is movable and is keyed by
integral molded ribs on the inner circumference of
the rotor hub to the splines on the external circum-
ference of the upper steering column shaft. The two
integral lobes of the turn signal cancel cam formation
on the lower surface of the clockspring rotor hub con-
tact the turn signal cancel actuator of the multi-func-
tion switch to provide automatic turn signal
cancellation. The yellow sleeved pigtail wire on theupper surface of the clockspring rotor connects the
clockspring to the driver airbag, while two single pig-
tail wires connect to the feed and ground terminals of
the horn switch located within the hub cavity of the
steering wheel.
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 is centered when it is installed on the
steering column. Centering the clockspring indexes
the clockspring tape to the movable steering compo-
nents 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. The clockspring must
be re-centered following completion of this service or
the tape may be damaged.
Service replacement clocksprings are shipped pre-
centered and with the mounting screws backed out
from the case far enough to engage the access holes
in the upper surface of the rotor. The mounting
screws secure the centered clockspring rotor to the
clockspring case during shipment, but allow free
rotation of the rotor once the clockspring is properly
installed on the steering column. The clockspring
mounting screws should not be tightened into the
clockspring case until the clockspring has been
installed on the steering column. If the screws are
tightened into or removed from the case 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
six to seven complete rotations) as the steering wheel
can be turned from stop to stop. Centering the clock-
spring indexes the clockspring tape to other steering
components so that it can operate within its designed
travel limits. The rotor of a centered clockspring can
be rotated three to three and one-half turns in either
direction from the centered position, without damag-
ing 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 the mounting screws
backed out from the case far enough to engage the
access holes in the upper surface of the rotor (Fig.
15). The clockspring mounting screws should not be
tightened into the clockspring case until the clock-
spring has been installed on the steering column. If
the screws are tightened into or removed from the
case before the clockspring is installed on a steering
column, the clockspring centering procedure must be
performed.

DRIVER AIRBAG
DESCRIPTION
The color-keyed, 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 armature of the
horn switch within the hub cavity of the four-spoke
steering wheel. Concealed beneath the driver airbag
trim cover are the folded airbag cushion, the airbag
cushion retainer, the airbag housing, the airbag infla-
tor, and the retainers that secure the inflator to the
airbag housing (Fig. 19). The airbag cushion, hous-
ing, and inflator are secured within an integral
receptacle molded into the back of the trim cover.
The airbag used in this model is a Next Genera-
tion-type that complies with revised federal airbag
standards to deploy with less force than those usedin some prior models. A radial deploying fabric cush-
ion with internal tethers is used. The airbag inflator
is a solid fuel, pyrotechnic-type unit with four studs
and is secured by four hex nuts to four studs on the
airbag cushion retainer ring to the back of the
stamped metal airbag housing. A keyed connector
receptacle on the driver airbag inflator connects the
inflator initiator to the vehicle electrical system
through a yellow-jacketed, two-wire pigtail harness of
the clockspring.
The driver airbag and trim cover unit cannot be
repaired, and must be replaced if deployed, faulty, or
in any way damaged.

OPERATION
The driver airbag is deployed by electrical signals
generated by the Airbag Control Module (ACM)
through the driver airbag squib circuit to the initia-
tor in the airbag inflator (Fig. 20). When the ACM
sends the proper electrical signal to the initiator the
electrical energy generates enough heat to initiate a
small pyrotechnic charge which, in turn, ignites
chemical pellets within the inflator. Once ignited,
these chemical pellets burn rapidly and produce a
large quantity of inert gas. The inflator is sealed to
the back of the airbag housing and a diffuser in the
inflator directs all of the inert gas into the airbag
cushion, causing the cushion to inflate. As the cush-
ion inflates, the driver airbag trim cover will split at
predetermined breakout lines, then fold back out of
the way. Following an airbag deployment, the airbag
cushion quickly deflates by venting the inert gas
towards the instrument panel through filtered vents
within the fabric used to construct the back (steering
wheel side) panel of the airbag cushion.Some of the chemicals used to create the inert gas
may be considered hazardous while in their solid
state before they are burned, but they are securely
sealed within the airbag inflator. Typically, all poten-
tially hazardous chemicals are burned during an air-
bag deployment event. The inert gas that is produced
when the chemicals are burned is harmless. How-
ever, a small amount of residue from the burned
chemicals may cause some temporary discomfort if it
contacts the skin, eyes, or breathing passages. If skin
or eye irritation is noted, rinse the affected area with
plenty of cool, clean water. If breathing passages are
irritated, move to another area where there is plenty
of clean, fresh air to breath. If the irritation is not
alleviated by these actions, contact a physician.
REMOVAL
The following procedure is for replacement of a
faulty or damaged driver airbag. If the airbag is
faulty or damaged, but not deployed, review the rec-
ommended procedures for handling non-deployed
supplemental restraints. (Refer to 8 - ELECTRICAL/
RESTRAINTS - STANDARD PROCEDURE - HAN-
DLING NON-DEPLOYED SUPPLEMENTAL
RESTRAINTS). If the driver airbag has been
deployed, review the recommended procedures for
service after a supplemental restraint deployment
before removing the airbag from the vehicle. (Refer to
8 - ELECTRICAL/RESTRAINTS - STANDARD PRO-
CEDURE - SERVICE AFTER A SUPPLEMENTAL
RESTRAINT DEPLOYMENT).
