The shape, holes, and
copper-colored stud indicate this
is not a Genuine Subaru inflator.
NOTE: Some models utilize a “tether clip” to secure the upper portion of the “A” pillar trim. The
tether clip is located just below where the “A” pillar trim meets the head liner. If the tether clip
becomes damaged, it MUST be replaced. The illustrations and photos below show the location of the
tether clip and how to release it. It is STRONGLY RECOMMENDED to use the release tool (p.n.
SOA635147) specifically designed for tether clip removal. Each Retailer has been supplied with 2 of
these tools. If the tool is unavailable, a needle-nosed plier can be used to CAREFULLY release the
tether clip as shown in the illustration below.

Replacement Airbag Module Assembly Part Number: 98279AJ06A
CAUTION: Refer to the “CAUTION” section in the General Description portion of Airbag
System AB in the Body Section of the Service Manual before handling or servicing any airbag
module!
STEP 1- PREPARATION:
• Record the customer’s radio station presets (and Navigation favorites where applicable).
• Turn the ignition “OFF”.
• Disconnect the Negative (ground) cable from the battery and wait at least 60 seconds before
proceeding further.
• Follow the procedures in the applicable Service Manual for removing the instrument panel
assembly as required to access the passenger side airbag module.
• Disconnect the wiring harness and remove the airbag module.
IMPORTANT: Whenever beginning to remove (or install) the airbag assembly, and periodically
while performing the procedure or after stepping away, remove any possible static charge
from your body by momentarily touching a clean, bare metal ground point on the vehicle (e.g.
the door striker). Remove from your person all electronic devices including cell phones before
proceeding.
IMPORTANT: DO NOT destroy or damage the Shipping Box as it MUST be used for the
original module’s return shipping.
STEP 2- To access the passenger’s airbag module, the complete instrument panel assembly must be
removed. Follow the procedures in the applicable Service Manual for removing the instrument panel
assembly in addition to the necessary related interior trim components.
NOTE: When removing the “A” pillar trim, be VERY CAREFUL not to damage the upper trim
retaining (tether) clip. The clip is located just below where the trim panel meets the head liner. If the
tether clip becomes damaged, it MUST be replaced. The illustrations below show how to release the
tether clip and remove the “A” pillar trim. It is STRONGLY RECOMMENDED to use the release
tool (p.n. SOA635147) specifically designed for tether clip removal. See pg. 8 of this bulletin for
more information.
Once the instrument panel assembly has been removed from the vehicle, CAREFULLY release the
retaining claws and separate the airbag bag module.

CAUTION: Refer to the “CAUTION” section in the General Description portion of Airbag
System AB in the Body Section of the Service Manual before handling or servicing any airbag
module!
STEP 1- PREPARATION:
Before proceeding, confirm the airbag lamp cycles on and then off normally as part of the self-check
and using SSM, confirm there are no DTCs stored in the airbag system. Inspect the dash area around
the passenger airbag module for any marks or damage. Document and photograph any conditions
observed before starting this procedure.
• Turn the ignition “OFF”.
• Disconnect the Negative (ground) cable from the battery and wait at least 60 seconds before
proceeding further.
• Remove the glove box assembly following the procedure in the applicable Service Manual
and using the tips below.
o The glove box is held in place by 8 screws. The 2 upper left and right hand corner screws
have a distinctive gold finish and 10mm hex head. It is helpful to leave these 2 screws
until last when removing and install first during replacement to support the weight of the
assembly.
o It is necessary to remove the knockout plugs (stopper in the Service Manual) to gain
access to all the mounting screws.
•
o It is possible to leave the stoppers in place during servicing by carefully bending in the
sides of the glove box until the stoppers are cleared.
To prevent damage, do not bend them in any further than necessary.
IMPORTANT: Whenever beginning to remove (or install) the airbag assembly, and periodically
while performing the procedure or after stepping away, remove any possible static charge from
your body by momentarily touching a clean, bare metal ground point on the vehicle (e.g. the
door striker). Remove from your person all electronic devices including cell phones before
proceeding.

•
Disconnect the airbag module harness
connector (A) and release it from the support
beam bracket.
•
Remove the 3 retaining bolts and
CAREFULLY remove the airbag module
from the vehicle by carefully releasing the
cover tabs from the underside of the dash and
pushing the module up and out. Use caution
and protective coverings to avoid damaging the dashboard pad. Place the airbag module on a
clean cloth to protect the module lid from scuffs, scratches or other damage.
STEP 2- TRIM COVER / LID REMOVAL:
VERY IMPORTANT: Before removing the original
trim cover / lid from the module, note the orientation
of the cover in relation to the module as the module can
be installed upside down in the cover. (TIP: The bottom
or harness side goes toward the “SRS AIRBAG” side of the
cover as shown.)
CAUTION: During cold temperatures always let the cover
warm to room temperature before attempting claw removal.
In all cases, limit any distortion of the airbag cover to avoid
damaging it.
•
•
Using a trim clip removal tool and starting on the harness-side of the module assembly as
shown in the sequence below, CAREFULLY insert the tool and twist ONLY AS MUCH AS
IS REQUIRED to release the slightly longer center retaining claw from the trim cover. Once
released with the tool, the other 6 claws will release easily by hand.
Rotate the inflator portion of the assembly outward from the cover to release the 7 label-side
claws and separate the cover from the module. No tool is required as all the 7 label-side
claws are the same size.

Step 3- Confirm the orientation is correct as outlined earlier in this bulletin. Refit the original
cover, if reusable, onto the replacement module assembly. Make sure all the claws are fully engaged
(see Figure 1 above). When properly installed, the cover should feel loose with a small amount of
freeplay. If the cover is tight (no freeplay or looseness), it most likely is not fully engaged onto the
claws.

Step 4- VERY IMPORTANT: Record the alpha-numeric serial numbers for BOTH the original
and the replacement module assemblies on the hard copy of the Repair Order. See pages 40 & 41
for serial number location photos. For SOA and SDC Retailers ONLY, this information will be
required for claim approval. For SNE retailers, this information will be required for completion of
the Part Return Notice which will be forwarded by the retailer to the PCC.
Step 5- After confirming the cover is properly fitted to the module, reinstall the module assembly
in reverse order of disassembly. Before installing the glove box assembly, reconnect the negative
battery cable. Turn the ignition key “ON” and confirm the AIRBAG warning light comes on then
cycles off properly. Once proper warning light operation is confirmed, reinstall the glove box
assembly.
Step 6- Place the removed module assembly into the returnable shipping box. Refer to the
SHIPPING DOCUMENTATION AND INSTRUCTIONS (Appendix A) found toward the end of
this bulletin.
IMPORTANT: UNDER NO CIRCUMSTANCES SHOULD ANY AIRBAG MODULES BE
RETURNED TO SUBARU OF AMERICA, INC.
