. It the green light on the tool comes on, the air-
bag igniter circuit is defective and cannot deploy
the airbag. Go to Damaged Airbag Special
Procedure.
.lftheredlightonthetool comes on, the airbag is
ready to be deployed.
Push the tool's deployment switch. The airbag
should deploy (deployment is both highly audible
and visible; a loud noise and rapid inflation of the
bag, followed by slow deflation).
. lf the airbags deploy and the green light on the
tool comes on, continue with this procedure.
. lf an airbag doesn't deploy, yet the green light
comes ON, its igniter is defective. Go to Dam-
aged Airbag Special Procedure.
. During deployment, the airbag can become hot
enough to burn you, Wait thirty minutes after
deployment before touching the airbag.
Dispose of the complete airbag. No part of it can be
reused. Place it in a sturdy plastic bag, and seal it
securety.
CAUTION:
. Wear a faco shield and gloves when handling a
deployed airbag.
. Wash your hands and rinse them well with
water after handling a deployed airbag.

Deploying tho Airbag: Out-ot.vohicle
lf an intact airbag has been removed from a scrapped
vehicle, or has been found defective or damagsd during
transit. storage or seryice, it should be deployed as fol-
lows:
'L Confirm that the special tool is functioning properly
by following the check procedure on this page or on
the tool label.
2. Position the airbag face up, outdoors on flat ground
at least thirty feet (10 m) from any obstacles or peo-
Dte,
3. Follow steps 6, 7, 8. and 9 of the in-vehicle deploy-
ment proceoure.

Procgdure
!@ r an airbag {or seat Beh rensioner} cannol
be doployod, it should not be treated as normal scrap; it
should still be considered a pot€ntially explosive device
lhat can cause serious iniury.
1. lf installed in a vehicle. follow the removal proce-
dure on page 24-3 and 24-87 through 90.
2. In all cases, make a short circuit by twisting together
the two airbag inflator wires.
3. Package the airbag in exactly the same packaging
that the new reDlacement Dart came in.
4. Mark the outside of the box "DAMAGED AIRBAG
{or TENSIONER) NOT DEPLOYED" so it does not
get confused with your parts stock.5. Contact your Honda District Service Manager forhow and where to return it for disposal.
Deployment Tool: Check Procedure
Connect the yellow clips to both switch protector
handles on the tool; connect the tool to a battery.
Push the operation switch: green means the tool is
OK: red means the tool is faultv.
Disconnect the baftery and the yellow clips.
