nector is secured by a tight snap fit into the airbag
inflator connector receptacle, which is located on the
back of the driver airbag housing. Firmly grasp and
pull or gently pry on the clockspring driver airbag
pigtail wire connector insulator and pull the insula-
tor straight out from the airbag inflator to disconnect
it from the connector receptacle.

(6) Remove the driver airbag from the steering

wheel.

(7) If the driver airbag has been deployed, the

clockspring must be replaced. (Refer to 8 - ELECTRI-
CAL/RESTRAINTS/CLOCKSPRING - REMOVAL).

DISASSEMBLY

(1) Place the new driver airbag trim cover on a

suitable work surface with the airbag receptacle fac-
ing up. Be certain to take the proper precautions to
prevent the trim cover from receiving cosmetic dam-
age during the following procedures.

(2) Carefully position the driver airbag into the

trim cover receptacle. Be certain that the horn switch
feed and ground pigtail wires are not pinched
between the airbag housing and the trim cover lock-
ing blocks.

(3) Engage the upper and lower trim cover locking

blocks with the lip of the driver airbag housing, then
engage the locking blocks on each side of the trim
cover with the lip of the housing. Be certain that
each of the locking blocks is fully engaged on the lip
of the airbag housing (Fig. 26).

(4) Reinstall the horn switch ground pigtail wire

eyelet terminal over the upper right inflator stud on
the back of the driver airbag housing.

(5) Reinstall the upper and lower airbag trim cover

retainers over the inflator studs on the back of the
driver airbag housing. Be certain that the tabs on
each retainer are engaged in the slots of the upper
and lower trim cover locking blocks (Fig. 25).

(6) Install and tighten the four nuts that secure

the trim cover retainers to the inflator studs on the
back of the driver airbag housing. Tighten the nuts
to 7 N·m (60 in. lbs.).

(7) Engage the horn switch feed pigtail wire con-

nector retainer in the mounting hole in the upper
trim cover retainer.

(8) Reinstall the driver airbag onto the steering

wheel. (Refer to 8 - ELECTRICAL/RESTRAINTS/
DRIVER AIRBAG - INSTALLATION).

(1) Position the driver airbag close enough to the

steering wheel to reconnect the two electrical connec-
tions at the back of the airbag housing.

(2) When installing the driver airbag, reconnect

the clockspring driver airbag pigtail wire connector
to the airbag inflator connector receptacle by press-
ing straight in on the connector (Fig. 22). You can be
certain that the connector is fully engaged in its
receptacle by listening carefully for a distinct, audi-
ble click as the connector snaps into place.

(3) Reconnect the clockspring horn switch pigtail

wire connector to the horn switch feed pigtail wire
connector located on the back of the driver airbag
housing.

(4) Carefully position the driver airbag in the

steering wheel. Be certain that the clockspring pig-
tail wires and the steering wheel wire harness in the
steering wheel hub area are not pinched between the
driver airbag and the steering wheel armature.

(5) From the underside of the steering wheel,

install and tighten the two screws that secure the
driver

airbag

the

steering

wheel

armature.

Tighten the screws to 10 N·m (90 in. lbs.).

(6) Do not reconnect the battery negative cable at

this time. The supplemental restraint system verifi-
cation test procedure should be performed following
service of any supplemental restraint system compo-
nent. (Refer to 8 - ELECTRICAL/RESTRAINTS -
