FRONT PASSENGER AIR BAG MODULE
FRONT PASSENGER AIR BAG MODULE
PFP:K8515
Removal and InstallationEHS001XU
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. Refer to
SRS-41, "
WIRING HARNESS MODIFICATION"for wiring harness modification procedure.
REMOVAL
CAUTION:
lDo not attempt to repair or replace damaged direct-connect front passenger air bag module con-
nectors. If a direct-connect harness connector is damaged, the front passenger air bag must be
replaced and the wiring harness modified.
lBefore servicing SRS, turn the ignition switch off, disconnect both battery cables and wait at least
3 minutes.
lAlways work from the side of or under front passenger air bag module.
1. Remove the glove box, then remove instrument panel. Refer toIP-10, "
INSTRUMENT PANEL ASSEM-
BLY".
2. Remove 4 bolts retaining front passenger air bag module to the
steering member.
3. Disconnect the front passenger air bag module connector.
CAUTION:
lWhen servicing the SRS, do not work from directly in front
of air bag module.
lAlways place front passenger air bag module with caution
label side facing upward.
lDo not insert any foreign objects (screwdriver, etc.) into air
bag module or harness connectors.
lDo not disassemble air bag module.
lDo not use old nuts after removal; replace with new nuts.
lDo not expose the front passenger air bag module to tem-
peratures exceeding 90°C(194°F). TORX bolts (T30)

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:
lDo not attempt to repair or replace damaged direct-connect front passenger air bag module con-
nectors. If a direct-connect harness connector is damaged, the front passenger air bag must be
replaced and the wiring harness modified.

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.
