Dodge Durango (HB). Manual - part 553

WARNING: To avoid personal injury or death, the driver airbag trim cover must never be painted. Replace-
ment trim covers are serviced in the original colors. Paint may change the way in which the material of the
trim cover responds to an airbag deployment. Failure to observe this warning could result in occupant inju-
ries upon airbag deployment.

NOTE: The following procedures can be used to replace the driver airbag trim cover and horn switch unit
for service. If the driver airbag is faulty or deployed, the entire driver airbag, trim cover and horn switch
must be replaced as a unit.

1. Place the driver airbag on a suitable work surface

with the airbag cushion facing up.

2. Fold the two flaps (1) of cushion material up

around the sides and over the top of the airbag
cushion retainer strap (2).

3. Position the new driver airbag trim cover over the

airbag cushion, then push the receptacle of the trim
cover down evenly over the cushion. Be certain
that the cushion material flaps remain oriented over
the cushion retainer strap as they were in Step 2.

4. Turn the driver airbag and the new driver airbag

trim cover over as a unit, and place the unit on a
suitable clean and dry work surface with the airbag
cushion facing down. Be certain to take the proper
precautions to prevent the trim cover from receiving
cosmetic damage during the following procedures.

5. Be certain that the horn switch feed and ground

pigtail wires are routed through the clearance notch
at the top of the airbag housing (3), between the
housing and the upper vertical wall of the trim
cover receptacle.

6. Work around the perimeter of the unit engaging

each of the twelve hooks (5 and 6) on the driver
airbag housing through the windows in the walls of
the trim cover receptacle.

7. Install the horn switch ground pigtail wire eyelet ter-

minal (2) over the upper right inflator stud on the
back of the driver airbag housing.

8. Install and tighten the nut that secures the horn

switch ground pigtail wire eyelet terminal to the
upper right inflator stud on the back of the driver
airbag housing. Tighten the nut to 7 N·m (65 in.
lbs.).

9. Using hand pressure, push the integral retainer of

the horn switch feed pigtail wire connector (1) into
the locator hole just above the upper right inflator mounting stud on the back of the airbag housing.

10. After the driver airbag has been assembled, try pulling the trim cover and the airbag housing away from each

other. This action will fully seat the edges of the windows into the cradles of the hooks.

11. Before reinstalling the airbag onto the steering

wheel, check that the blocking tab (1) in each of
the trim cover windows is oriented over the airbag
housing hook (4) as shown.

12. Reinstall the driver airbag onto the steering wheel

(Refer

DRIVER AIRBAG - INSTALLATION).

INSTALLATION

WARNING: To avoid personal injury or death, on vehicles equipped with airbags, disable the supplemental
restraint system before attempting any steering wheel, steering column, airbag, occupant classification sys-
tem, seat belt tensioner, impact sensor, or instrument panel component diagnosis or service. Disconnect
and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge
before performing further diagnosis or service. This is the only sure way to disable the supplemental
restraint system. Failure to take the proper precautions could result in accidental airbag deployment.

WARNING: To avoid personal injury or death, use extreme care to prevent any foreign material from enter-
ing the driver airbag, or becoming entrapped between the driver airbag cushion and the driver airbag trim
cover. Failure to observe this warning could result in occupant injuries upon airbag deployment.

WARNING: To avoid personal injury or death, the driver airbag trim cover must never be painted. Replace-
ment airbags are serviced with trim covers in the original colors. Paint may change the way in which the
material of the trim cover responds to an airbag deployment. Failure to observe this warning could result in
occupant injuries upon airbag deployment.

NOTE: 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 recommended procedures for handling non-deployed sup-
plemental restraints. (Refer to 8 - ELECTRICAL/RESTRAINTS - STANDARD PROCEDURE - HANDLING NON-
DEPLOYED

RESTRAINTS - SERVICE INFORMATION

1. Position the driver airbag (1) close enough to the

steering wheel to reconnect the three electrical
connections on the back of the airbag housing.

2. When installing the driver airbag, reconnect the two

clockspring driver airbag pigtail wire connectors (3)
to the airbag inflator connector receptacles by
pressing straight in on the connector. Be certain to
engage each keyed and color-coded connector to
the matching connector receptacle. You can be cer-
tain that each connector is fully engaged in its
receptacle by listening carefully for a distinct, audi-
ble click as the connector latches snap into place.

3. Reconnect the steering wheel wire harness con-

nector (2) for the horn switch to the horn switch
feed pigtail wire connector (4), which is located on
the back of the driver airbag housing.

4. Carefully position the driver airbag (1) in the steer-

ing wheel (2). Be certain that the clockspring pigtail
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 (3) that secure the
driver airbag to 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 verification
test procedure should be performed following ser-
vice of any supplemental restraint system compo-
nent. (Refer to 8 - ELECTRICAL/RESTRAINTS -

IMPACT SENSOR

DESCRIPTION

FRONT

Two front impact sensors (1) are used on this model,
one each for the left and right sides of the vehicle.
These sensors are mounted remotely from the impact
sensor that is internal to the Occupant Restraint Con-
troller (ORC). Each front sensor is secured with a
screw to the backs of the right and left vertical mem-
bers of the radiator support within the engine compart-
ment. The sensor housing has an integral connector
receptacle (4), an integral anti-rotation pin (3), and an
integral mounting hole (2) with a metal sleeve to pro-
vide crush protection.

The right and left front impact sensors are identical in construction and calibration. A cavity in the center of the
molded black plastic impact sensor housing contains the electronic circuitry of the sensor which includes an elec-
tronic communication chip and an electronic impact sensor. Potting material fills the cavity to seal and protect the
internal electronic circuitry and components. The front impact sensors are each connected to the vehicle electrical
system through a dedicated take out and connector of the headlamp and dash wire harness.

The impact sensors cannot be repaired or adjusted and, if damaged or faulty, they must be replaced.

SIDE

Six side impact sensors (1) are used on this model
when it is equipped with the optional side curtain air-
bags, three each for the left and right sides of the
vehicle. These sensors are mounted remotely from the
impact

sensor

that

internal

the

Occupant

Restraint Controller (ORC). Each side sensor is
secured with a screw to the inner right or left B-pillar,
C-pillar or D-pillar within the passenger compartment.
The sensor housing has an integral connector recep-
tacle (4), an integral anti-rotation pin (3), and an inte-
gral mounting hole (2) with a metal sleeve to provide
crush protection.

The right and left side impact sensors are identical in construction and calibration. A cavity in the center of the
molded black plastic impact sensor housing contains the electronic circuitry of the sensor which includes an elec-
tronic communication chip and an electronic impact sensor. Potting material fills the cavity to seal and protect the
internal electronic circuitry and components. The side impact sensors are each connected to the vehicle electrical
system through a dedicated take out and connector of the body wire harness.

The impact sensors cannot be repaired or adjusted and, if damaged or faulty, they must be replaced.
