before disconnecting the battery cables.
1, Disconnect the battery negative cable and then thepositive cable. Then connect the short connoctor{sl
{RED} to the airbag(s) (see page 23-272).
2. Connect Test Harness B between the SRS unit and
SRS main harness 18-P connector.

Reconnect the front passenger's airbag connector,
then measure the resistance between the 82 termi-
nal and the B8 terminal.

lf resistance is more than 0.2 k0, go to step 4.
lf resistance is less than 0.2 kO, the SRS unit is
faulty. Substitute a known-good SRS unit and
recheck the voltages according to the chart onpage 23-283.

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
ready to be deployed.
Push the tool's deployment switch. Th6 sirbag
should deploy (deployment is both highly audible
and visibls - a loud noise and raDid inflation of the
bag, followed by slow deflationl.
. lf audible/visible deploym€nt happsns and the
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.

1. Confirm that the special tool is functioning properly
by following the check procedure on this page or on
the tool box label.
2. Remove the short connector from the airbag con-
nector.
3. Folfow steps 5,6,7, and 8 of the in-car deployment

2. In all cases, make sure a short connector is properly
installed on the airbag conn€ctor.
3. Package the airbag in sxacily the same packaging
that the now replacement part cama in.i[. Mark the outside 0f the box "DAMAGED AIRBAG

1. Connect the yellow clips to both switch protector
handles on the tool; connect the tool to a battery.
