Step
1 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 connector (AB26) from the
seat belt pretensioner (RH). <Ref. to SB-8,
Front Seat Belt.>
3)Disconnect the connector (AB25) from
(AB24).
4)Disconnect the connector (AB18) from the
airbag control module. <Ref. to AB-15, Airbag
Control Module.>
5)Connect the connector (1I) in test harness I
or I2 to the connector (AB18).
6)Disconnect the connector (AB28) from the
side airbag sensor (RH), and connect the con-
nector (1G) in test harness G to connector
(AB28).
7)Measure the resistance between connector
(3I) in test harness I or I2 and connector (3G)
in test harness G.
