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)
: 24.5 N·m (2·5 kg-m, 18 ft-lb)

lDo not allow oil, grease or water to come in contact with the
air bag module.
lFor removal/installation of the direct-connect SRS connec-
tors, refer toSRS-8, "
Direct-Connect SRS Component Con-
nectors".
INSTALLATION
Original Passenger Air Bag Module
To install, reverse the removal procedure.
lFor removal/installation of the direct-connect SRS connectors, refer toSRS-8, "Direct-Connect SRS Com-
ponent Connectors".
CAUTION:
lAlways work from the side of or under front passenger air bag module.
lAfter the work is completed, perform self-diagnosis to check that no malfunction is detected.
Refer toSRS-18, "
SRS Operation Check".
Service Replacement Passenger Air Bag Module
1. Install the instrument panel assembly. Refer toIP-10, "INSTRUMENT PANEL ASSEMBLY".
2. Install the front passenger air bag module to the steering mem-
ber.
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:
lAlways work from the side of or under front passenger air bag module.
lAfter the work is completed, perform self-diagnosis to check that no malfunction is detected.
Refer toSRS-18, "
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:
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.

DISPOSAL OF AIR BAG MODULE AND SEAT BELT PRE-TENSIONERPFP:00014
Caution for Air Bag Module and Seat Belt Pre-tensionerEHS001Y2
lBefore disposing of air bag module, seat belt pre-tensioner or vehicle equipped with such systems, deploy
the systems. If such systems have already been deployed due to an accident, dispose of them as indi-
cated in “SRS-49, "
DISPOSAL OF AIR BAG MODULE AND SEAT BELT PRE-TENSIONER".
lWhen deploying the air bag module or seat belt pre-tensioner, always use the Special Service Tool
Deployment tool [KV99106400].
lWhen deploying the air bag module or seat belt pre-tensioner, stand at least 5 m (16 ft) away from the
component being deployed.
lWhen deploying air bag module or seat belt pre-tensioner, a fairly loud noise is made, followed by smoke
being released. The smoke is not poisonous, however, be careful not to inhale smoke since it irritates the
throat and can cause choking.
lOnly deploy one air bag module or seat belt pre-tensioner at a time.
lDue to heat, leave deployed air bag module unattended for at least 30 minutes after deployment. Leave
deployed seat belt pre-tensioner unattended for at least 10 minutes after deployment.
lBe sure to wear gloves when handling a deployed air bag module or seat belt pre-tensioner.
lNever apply water to the deployed air bag module or seat belt pre-tensioner.
lWash your hands thoroughly after finishing work.
lPlace the vehicle outdoors with an open space of at least 6 m (20 ft) on all sides when deploying air bag
module or seat belt pre-tensioner while mounted in vehicle.
lUse a voltmeter to make sure the vehicle battery is fully charged.
lDo not dispose of the air bag module or seat belt pre-tensioner undeployed.
CHECKING DEPLOYMENT TOOL
Connecting to Battery
CAUTION:
The battery must show voltage of 9.6V or more.
Remove the battery from the vehicle and place it on dry wood blocks
approximately 5 m (16 ft) away from the vehicle.
lWait 3 minutes after the vehicle battery is disconnected before
proceeding.
lConnect red clip of deployment tool to battery positive terminal
and black clip to negative terminal.
Makesurethepolarityiscorrect.Therightsidelampinthetool
marked “deployment tool power” should glow with a green
light. If the right side lamp glows red, reverse the connections
to the battery.
Deployment Tool Check
Place the deployment tool switch to the ON position. The left side
lamp in the tool, marked “air bag connector voltage” should illumi-
nate. If it does not illuminate, replace the tool.
