FRONT PASSENGER AIR BAG MODULE

FRONT PASSENGER AIR BAG MODULE

Removal and Installation

INFOID:0000000005147759

The passenger air bag module originally installed in the vehicle uses direct-connect style harness connectors.

Service replacement passenger air bag modules use tab-locking style harness connectors. If the passenger

air bag module is replaced or if the direct-connect harness connectors are damaged, the vehicle wiring har-

ness must be modified to allow connection of the service replacement passenger air bag module. Follow the

wiring harness modification procedure within this section.

REMOVAL

CAUTION:

• Do not attempt to repair or replace damaged direct-connect front passenger air bag module connec-

tors. If a direct-connect harness connector is damaged, the front passenger air bag must be

replaced and the wiring harness modified.

• Before servicing SRS, turn the ignition switch off, disconnect both battery terminals and wait at least

three minutes.

• Always work from the side of or under front passenger air bag module.
1. Disconnect both the negative and positive battery terminals, then wait at least three minutes.
2. Remove the glove box. Refer to

IP-17, "Exploded View"

3. Remove two nuts (through glove box opening) retaining front passenger air bag module to instrument

panel crossmember.

4. Disconnect the air bag module electrical connectors.

• For removal/installation of the direct-connect SRS connectors, refer to

SRC-9, "Direct-connect SRS

Component Connectors"

5. Remove the instrument panel assembly from the vehicle. Refer to

IP-12, "Removal and Installation"

6. Remove front passenger air bag module nuts and remove air

bag module from the instrument panel assembly.

CAUTION:

• When servicing the SRS, do not work from directly in front of

air bag module.

• Always place front passenger air bag module with caution

label side facing upward.

• Do not insert any foreign objects (screwdriver, etc.) into air

bag module or harness connectors.

• Replace the air bag module if it has been dropped or sus-

tained an impact.

• Do not allow oil, grease or water to come in contact with the

air bag module.

• For removal/installation of the direct-connect SRS connec-

tors, refer to

nectors"

INSTALLATION

Original Passenger Air Bag Module

Installation is in the reverse order of removal.

• For removal and installation of the direct-connect SRS connectors, refer to

SRC-9, "Direct-connect SRS

Component Connectors"

CAUTION:

• Always work from the side of or under front passenger air bag module.

• After the work is completed, perform self-diagnosis to check that no malfunction is detected. Refer

SRC-13, "SRS Operation Check"

Service Replacement Passenger Air Bag Module

1. Install the front passenger air bag module to the instrument

panel pad assembly.

2. Install the instrument panel assembly. Refer to

IP-12, "Removal and Installation"

3. Connect the front passenger air bag module harness connector to yellow 4-pin service replacement air

bag connector and fasten connector to mounting bracket.

CAUTION:

• Always work from the side of or under front passenger air bag module.

• After the work is completed, perform self-diagnosis to check that no malfunction is detected. Refer

SRC-13, "SRS Operation Check"

WIRING HARNESS MODIFICATION

The passenger air bag module originally installed in the vehicle uses direct-connect style harness connectors.

Service replacement passenger air bag modules use tab-locking style harness connectors. If the passenger

air bag module is replaced or if the direct-connect harness connectors are damaged, the vehicle wiring har-

ness must be modified to allow connection of the service replacement passenger air bag module.

NOTE:

The wiring harness modification is to be performed only if the vehicle is equipped with the original passenger

air bag which uses direct-connect harness connectors. If the passenger air bag is to be replaced in a vehicle

that has already had the service replacement passenger air bag installed, the wiring harness modification is

not required.

CAUTION:

• Do not attempt to repair or replace damaged direct-connect front passenger air bag module connec-

tors. If a direct-connect harness connector is damaged, the front passenger air bag must be

replaced and the wiring harness modified.

• Before servicing SRS, turn the ignition switch off, disconnect both battery cables and wait at least 3

minutes.

• Always work from the side of or under front passenger air bag module.

• After the work is completed, perform self-diagnosis to check that no malfunction is detected. Refer

SRC-13, "SRS Operation Check"

1. Locate the yellow and orange direct-connect passenger air bag module harness connectors.
2. Use wire cutters to cut back both previously used direct-connect passenger air bag module harness con-

nectors from the vehicle wiring harness approximately 50 mm (1.9 in) from the connectors.

3. Remove approximately 150 mm (5.9 in) of the vehicle harness covering from the cut end.
4. Slide a piece of dual-wall heat shrink tubing (provided in the pas-

senger air bag service kit) onto each wire of the previously used

vehicle wiring harness.

5. Fold each wire back and insert into the end of the heat shrink

tubing so that the end of the wire is approximately centered in

the heat shrink tubing.

6. Use a heat gun to shrink the heat shrink tubing and seal the wire.
7. Use electrical tape to secure the modified circuits to the outside of the wiring harness.
8. Locate the front passenger air bag service replacement connec-

tor that is taped back to the main harness. Unwrap the tape to

access the yellow service replacement connector and remove

the dust cover from the connector.
