FRONT PASSENGER AIR BAG MODULE
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.
lAfter the work is completed, perform self-diagnosis to check that no malfunction is detected.
Refer toSRS-18, "
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.

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.
