Jeep XJ. Manual - part 129

Removal and Installation section of this group for the
procedures.

Use a vacuum cleaner to remove any residual pow-

der from the vehicle interior. Clean from outside the
vehicle and work your way inside, so that you avoid
kneeling or sitting on a non-cleaned area.

Be sure to vacuum the heater and air conditioning

outlets as well (Fig. 3). Run the heater and air con-
ditioner blower on the lowest speed setting and vac-
uum any powder expelled from the outlets. You may
need to vacuum the interior of the vehicle a second
time to recover all of the powder.

Place the deployed airbag modules in your vehicu-

lar scrap pile.

REMOVAL AND INSTALLATION

DRIVER SIDE AIRBAG MODULE

The following procedure is for replacement of a

faulty or damaged driver side airbag module. If the

driver side airbag has been deployed, the clockspring
must also be replaced. Refer to Clockspring in the
Removal and Installation section of this group for the
additional service procedures for the clockspring.

COMPONENTS YOU MUST FIRST DISCONNECT
AND ISOLATE THE BATTERY NEGATIVE (GROUND)
CABLE. THEN WAIT TWO MINUTES FOR THE SYS-
TEM CAPACITOR TO DISCHARGE BEFORE FUR-
THER SYSTEM SERVICE. THIS IS THE ONLY SURE
WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE
TO DO THIS COULD RESULT IN ACCIDENTAL AIR-
BAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.

•

WHEN REMOVING A DEPLOYED AIRBAG MOD-

ULE, RUBBER GLOVES, EYE PROTECTION, AND A
LONG-SLEEVED SHIRT SHOULD BE WORN. THERE
MAY BE DEPOSITS ON THE AIRBAG MODULE AND
OTHER INTERIOR SURFACES. IN LARGE DOSES,
THESE DEPOSITS MAY CAUSE IRRITATION TO THE
SKIN AND EYES.

REMOVAL

(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) From the underside of the steering wheel,

remove the two screws that secure the driver side
airbag module to the steering wheel (Fig. 4).

(3) Pull the airbag module away from the steering

wheel far enough to access the two wire harness con-
nectors on the back of the airbag module.

(4) Disconnect the clockspring horn switch wire

harness connector from the horn switch feed wire
connector, which is located on the back of the airbag
module.

(5) The clockspring airbag wire harness connector

is a tight snap-fit into the airbag module connector
receptacle, which is located on the airbag inflator on
the back of the airbag module. Firmly grasp and pull
or gently pry on the clockspring airbag wire harness
connector to disconnect it from the airbag module.
Do not pull on the clockspring wire harness to
disengage the connector from the airbag mod-
ule connector receptacle.

(6) Remove the driver side airbag module from the

steering wheel.

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

clockspring must be replaced. Refer to Clockspring

(1) When installing the driver side airbag module,

reconnect the clockspring airbag wire harness con-
nector to the airbag module connector receptacle by
pressing straight in on the connector. You can be cer-
tain that the connector is fully engaged by listening
carefully for a distinct audible click as the connector
snaps into place.

(2) Reconnect the clockspring horn switch wire

harness connector to the horn switch feed wire con-
nector, which is located on the back of the airbag
module.

(3) Carefully position the driver side airbag mod-

ule in the steering wheel. Be certain that the clock-
spring wire harnesses in the steering wheel hub area
are not pinched between the airbag module and the
steering wheel.

(4) From the underside of the steering wheel,

install and tighten the two driver side airbag module
mounting screws. Tighten the screws to 10.2 N·m (90
in. lbs.).

(5) Do not reconnect the battery negative cable at

this time. Refer to Airbag System in the Diagnosis
and Testing section of this group for the proper pro-
cedures.

DRIVER SIDE AIRBAG MODULE TRIM COVER

The horn switch is integral to the driver side air-

bag module trim cover. If either component is faulty
or damaged, the entire driver side airbag module
trim cover and horn switch unit must be replaced.
