PASSENGER AIR BAG (INFLATOR) MODULE
WARNING:

Never attempt to disassemble or repair the passenger air bag (inflator) module. If any abnormality is
found, be sure to replace it with new one as an assembly.

Be sure to read ªService Precautionsº in this section before starting to work and observe every pre-
caution during work. Neglecting them may result in personal injury or undeployment of the air bag
when necessary.
REMOVAL
1) Disconnect negative battery cable at battery.
2) Disable air bag system. Refer to ªDisabling Air Bag Systemº ear-
lier in this section.
3) Open glove box, then while pressing glove box stopper, pull out
glove box from instrument panel.
4) Remove glove box from instrument panel.
5) Remove passenger air bag (inflator) module attaching bolts and
screws, and passenger air bag (inflator) module from vehicle.
WARNING:

When carrying a live air bag (inflator) module, make
sure the bag opening is pointed away from you.
Never carry air bag (inflator) module by wires or con-
nector on the side of the module. In case of an acciden-
tal deployment, the bag will then deploy with minimal
chance of injury.

As the live passenger air bag (inflator) module must be
kept with its bag (trim cover) facing up while being
stored or left standing, place it on the workbench with
a slit or use the workbench vise to hold it securely at its
lower mounting bracket. This is necessary so that a
free space is provided to allow the air bag to expand in
the unlikely event of accidental deployment.

Observe ªService Precautionsº earlier in this section
for handling and storing it.
Otherwise personal injury may result.

NOTE:
The remaining steps are to be followed in the unlikely event
that the seat belt pretensioner did not activate after following
these procedures.
23) Ensure that the deployment harness has been disconnected
from the power source and that its two banana plugs have been
shorted together by fully seating one banana plug into the oth-
er.
24) Disconnect the deployment harness from the seat belt preten-
sioner.
WARNING:
