Step
1 CHECK SIDE AIRBAG HARNESS (RH).
1) Turn the ignition switch OFF, disconnect
the battery ground cable, and wait more
than 20 seconds.
2) Disconnect connector (AB26) from the seat
belt pretensioner (RH). <Ref. to SB-7, Front
Seat Belt.>
3) Disconnect connector (AB25) from (AB24).
4) Disconnect connector (AB18) from the air-
bag control module. <Ref. to AB-17, Airbag
Control Module.>
5) Connect connector (1I) in test harness I2 to
the connector (AB18).
6) Disconnect connector (AB28) from the side
airbag sensor (RH), and connect connec-
tor (1G) in test harness G to connector
(AB28).
7) Measure the resistance between connector
(3I) in test harness I2 and connector (3G) in
test harness G.
