CLOCKSPRING
DESCRIPTION
The clockspring assembly is secured with two inte-
gral plastic latches onto the steering column lock
housing near the top of the steering column, behind
the steering wheel. The clockspring consists of a flat,
round molded plastic case with a stubby tail that
hangs below the steering column and contains a con-
nector receptacle and a long pigtail wire with connec-
tor that face toward the instrument panel. Within
the plastic housing 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,
two auto-locking tabs, and three short pigtail wires
with connectors that face toward the steering wheel.
The lower surface of the rotor hub has two integral
turn signal cancelling cam lobes. Within the plastic
case and wound around the rotor spool is a long rib-
bon-like tape that consists of several thin copper wire
leads sandwiched between two thin plastic mem-
branes. The outer end of the tape terminates at the
connector receptacle and pigtail wire that face the
instrument panel, while the inner end of the tape
terminates at the pigtail wires on the hub of the
clockspring rotor that face the steering wheel.
Service replacement clocksprings are shipped pre-
centered and with a piece of tape covering theengaged auto-locking tabs. The auto-locking tabs
secure the centered clockspring rotor to the clock-
spring case during shipment, but these tabs are auto-
matically disengaged once the clockspring is installed
on the steering column. (Refer to 8 - ELECTRICAL/
RESTRAINTS/CLOCKSPRING - STANDARD PRO-
CEDURE - 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 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 upper steering column lock housing by
two integral plastic latches. The connector receptacle
on the tail of the fixed clockspring housing connect
the clockspring to the vehicle electrical system
through a take out with connector from the instru-
ment panel wire harness. The lower clockspring pig-
tail on the tail of the clockspring housing connect the
clockspring driver airbag circuits to a separate take
out and connector of the instrument panel wire har-
ness located near the lower instrument panel rein-
forcement, below the steering column. 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 two lobes on the
lower surface of the clockspring rotor hub contact a
turn signal cancel actuator of the multi-function
switch to provide automatic turn signal cancellation.
The pigtail wires on the upper surface of the clock-
spring connect the clockspring 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 spool 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

CHILD TETHER (Continued)

may be damaged. Service replacement clocksprings
are shipped pre-centered and with the auto-locking
tabs engaged. A piece of tape covers the auto-locking
tabs to discourage tampering. These auto-locking
tabs should not be disengaged until the clockspring
has been installed on the steering column. If this
shipping tape is removed or damaged, or if the auto-
locking tabs are disengaged before the clockspring is
installed on a steering column, the clockspring cen-
tering procedure must be performed. (Refer to 8 -
ELECTRICAL/RESTRAINTS/CLOCKSPRING -
STANDARD PROCEDURE - CLOCKSPRING CEN-
TERING).
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 the auto-locking tabs
engaged (raised). These auto-locking tabs should not
be disengaged until the clockspring has been
installed on the steering column. If the auto-locking
tabs are disengaged before the clockspring is
installed on a steering column, the clockspring cen-
tering procedure must be performed.

DRIVER AIRBAG
DESCRIPTION
The driver airbag protective trim cover is the most
visible part of the driver airbag. The airbag used in
this model is a Next Generation-type that complies
with revised federal airbag standards to deploy with
less force than those used in some prior models. The
driver airbag is located in the center of the steering
wheel, where it is secured with two screws to the
steering wheel armature. 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
trim cover to the airbag housing. The resistive mem-
brane-type horn switch is secured with heat stakes to
the inside surface of the airbag trim cover, between
the trim cover and the folded airbag cushion. The air-
bag inflator is a conventional pyrotechnic-type unit
that is secured with nuts to four studs on the back of
the stamped metal airbag housing.
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 fit over the infla-
tor mounting studs on the back of the airbag housing
and tabs on the retainer are engaged in slots on the
inside of the trim cover, securely locking the cover
into place. One horn switch pigtail wire has an eyelet
terminal connector that is captured on the upper left
inflator mounting stud between the inflator and the
upper trim cover retainer. The connector insulator of
the other horn switch pigtail wire is routed between
the upper right inflator mounting stud and the infla-
tor, where it is captured by a small plastic retainer
that is pushed onto the stud. The driver airbag can-
not be repaired, and must be replaced if deployed or
in any way damaged. The driver airbag trim cover
and horn switch are available as a unit, and may be
disassembled from the driver airbag for service
replacement.
OPERATION
The driver airbag is deployed by an electrical sig-
nal generated by the Airbag Control Module (ACM)
through the driver airbag line 1 and line 2 (or squib)
circuits. When the ACM sends the proper electrical
signal to the airbag inflator, 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 nitrogen gas.
The inflator is sealed to the back of the airbag hous-
ing and a diffuser in the inflator directs all of the
nitrogen gas into the airbag cushion, causing the
cushion to inflate. As the cushion inflates, the driverairbag trim cover will split at predetermined break-
out lines, then fold back out of the way along with
the horn switch. Following an airbag deployment, the
airbag cushion quickly deflates by venting the nitro-
gen gas towards the instrument panel through the
porous fabric material used on the steering wheel
side of the airbag cushion.
Some of the chemicals used to create the nitrogen
gas are considered hazardous in their solid state,
before they are burned, but they are securely sealed
within the airbag inflator. However, the nitrogen gas
that is produced when the chemicals are burned is
harmless. 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 noticed, rinse the affected area
with plenty of cool, clean water. If breathing pas-
sages 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 driver airbag
has been deployed, the clockspring and the steering
column assembly must also be replaced. (Refer to 8 -
ELECTRICAL/RESTRAINTS/CLOCKSPRING -

DRIVER AIRBAG (Continued)

switch is in its installed position, the only compo-
nents visible through the dedicated opening of the
cluster bezel are the switch face plate and nomencla-
ture, the key cylinder actuator, and a small round
lens with the text9Off9imprinted on it. The ªOnº
position of the switch is designated by text imprinted
upon the face plate of the switch, but is not illumi-
nated. The remainder of the switch is concealed
behind the switch face plate and the instrument
panel cluster bezel.
The passenger airbag on-off switch housing is con-
structed of molded plastic and has three integral
mounting tabs. These mounting tabs are used to
secure the switch to the back of the molded plastic
switch face plate with three small screws. The
molded plastic face plate also has three integral
mounting tabs that are used to secure the switch and
face plate unit to the instrument panel carrier with
three additional screws. Two short pigtail wires with
molded plastic connector insulators exit the back of
the switch housing and connect the switch to the
vehicle electrical system through two dedicated take
outs of the instrument panel wire harness. The har-
ness take outs are equipped with molded plastic con-
nector insulators that are keyed and latched to
ensure proper and secure switch electrical connec-
tions. The passenger airbag on/off switch cannot be
adjusted or repaired and, if faulty or damaged, the
switch must be replaced.
OPERATION
The passenger airbag on/off switch allows the cus-
tomer to turn the passenger airbag function On or
Off to accommodate certain uses of the right front
seating position where airbag protection may not be
desired. See the owner's manual in the vehicle glove
box for specific recommendations on when to enable
or disable the passenger airbag. The Off indicator of
the switch will be illuminated whenever the switch is
turned to the Off position. The ignition key is the
only key or object that should ever be inserted into
the switch. The on/off switch requires only a partial
key insertion to fully depress a spring-loaded locking
plunger. The spring-loaded locking plunger prevents
the user from leaving the key in the switch. The key
will be automatically ejected when force is not
applied. To actuate the passenger side airbag on/off
switch, insert the ignition key into the switch key
actuator far enough to fully depress the plunger and
rotate to the desired switch position. When the
switch key actuator is rotated to its clockwise stop
(the key actuator slot will be aligned with the Off
indicator lamp), the Off indicator is illuminated and
the passenger airbag is disabled. When the switch is
rotated to its counterclockwise stop (the key actuator
slot will be in a vertical position), the Off indicatorwill be extinguished and the passenger airbag is
enabled.
The passenger airbag on/off switch is connected in
series between the Airbag Control Module (ACM) and
the passenger airbag inflator unit. When the switch
is in the On position, the switch connects the ACM
directly to the passenger airbag inflator. When the
switch is in the Off position it interrupts the inflator
circuits, but replaces the normal resistance in these
circuits with an internal resistor. Thus, the ACM is
unable to distinguish the mode of the switch and still
sends an electrical signal as though it were deploying
the passenger airbag when it detects a sufficient
impact. However, the switch position should not be
changed while the ignition switch is in the On posi-
tion, as the ACM may detect a fault, record a Diag-
nostic Trouble Code (DTC), and illuminate the Airbag
indicator in response to a momentary open it senses
in the passenger airbag inflator circuits as the on/off
switch changes states.
REMOVAL
WARNING: DISABLE THE AIRBAG SYSTEM
BEFORE ATTEMPTING ANY STEERING WHEEL,
STEERING COLUMN, OR INSTRUMENT PANEL
COMPONENT DIAGNOSIS OR SERVICE. DISCON-
NECT AND ISOLATE THE BATTERY NEGATIVE
(GROUND) CABLE, THEN WAIT TWO MINUTES FOR
THE AIRBAG SYSTEM CAPACITOR TO DISCHARGE
BEFORE PERFORMING FURTHER DIAGNOSIS OR
SERVICE. THIS IS THE ONLY SURE WAY TO DIS-
ABLE THE AIRBAG SYSTEM. FAILURE TO TAKE
THE PROPER PRECAUTIONS COULD RESULT IN
ACCIDENTAL AIRBAG DEPLOYMENT AND POSSI-
BLE PERSONAL INJURY.
(1) Disconnect and isolate the battery negative
cable. If either of the airbags has not been deployed,
wait two minutes for the system capacitor to dis-
charge before further service.
(2) Remove the cluster bezel from the instrument
panel. (Refer to 23 - BODY/INSTRUMENT PANEL/
CLUSTER BEZEL - REMOVAL).
(3) Remove the glove box from the instrument
panel. (Refer to 23 - BODY/INSTRUMENT PANEL/
GLOVE BOX - REMOVAL).
(4) Reach through the glove box opening to access
and disconnect the two passenger airbag on/off
switch pigtail wire harness connectors from the
instrument panel wire harness connectors. These
connectors are retained on a bracket located on the
inboard glove box opening reinforcement (Fig. 20).
(5) Remove the three screws that secure the pas-
senger airbag on/off switch face plate to the instru-
ment panel (Fig. 21).
