Step
1 CHECK SIDE AIRBAG MODULE.
1)Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait more than
20 seconds.
2)Disconnect the connector (AB26) from the
seat belt pretensioner (RH). <Ref. to SB-8,
Front Seat Belt.>
3)Disconnect the connector (AB25) from
(AB24), and connect the connector (1F) in test
harness F to (AB24).
4)Connect the airbag resistor to connector (3F)
in test harness F.
5)Connect the battery ground cable, and turn
the ignition switch to ON.
2 CHECK SIDE AIRBAG HARNESS (RH).
1)Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait more than
20 seconds.
2)Disconnect the airbag resistor from test har-
ness F.
3)Disconnect the connector (AB18) from air
bag control module. <Ref. to AB-15, Airbag
Control Module.>
4)Connect the connector (1I) in test harness I
or I2 to connector (AB18).
5)Measure the resistance between connector
(3I) in test harness I or I2 and connector (3F) in
test harness F.
