CAUTION: Uss only a digital multimeter to check the system. lf it's not a Honda multimeter, make sure its output is
10 mA {0.01 Al or less when switched to the smallest value in the ohmmeter rang€. A tester with a highor ouiput could
damage the airbag circuit or cause accidental airbag deployment and possible iniury

Airbag Assembly Disposal (cont'd)
Connect a l2 volt batterv to the tool:
. lf the green light on the tool comes on, th€
airbag igniter circuit is d€fective and cannot
deploy the airbag. Go to Dsmag€d Airbag
Special Procedure.
. lf the red light on the tool comes on, the airbag is

green light on the tool comes on, continus with
this Drocedure.
. lf the airbag doesn't deploy, yet the green light
comes ON, its igniter is dofectiv€. Go to
Damaged Airbag Special Procedure.
@ During deploym€nt, the airbsg assom-
bly can become hot enough to burn you. Wait thirty
minutes after deployment beforo touching the
assemblv.
Dispose of the complete airbag sssembly. No pan
of it can be reused. Place it in I sturdy plastic bag
and seal it securelv.
