DIAGNOSTIC CHART WITH DIAGNOSTIC TROUBLE CODE (DTC)
Step
1 CHECK SIDE AIRBAG HARNESS (LH).
1) Turn the ignition switch OFF, disconnect
the battery ground cable, and wait more
than 20 seconds.
2) Disconnect the connector (AB21) from the
seat belt pretensioner (LH). <Ref. to SB-7,
Front Seat Belt.>
3) Disconnect connector (AB20) from (AB19).
4) Disconnect connector (AB17) from the air-
bag control module. <Ref. to AB-17, Airbag
Control Module.>
5) Connect connector (1I) in test harness I2 to
connector (AB17).
6) Disconnect connector (AB23) from the side
airbag sensor (LH), and connect connec-
tor (1G) in test harness G to connector
(AB23).
7) Measure the resistance between connector
(3I) in test harness I2 and connector (3G) in
test harness G.

Is the measured value less than the speci-
fied value?
2 CHECK SIDE AIRBAG HARNESS (RH).
Measure the resistance between connector
(3I) in test harness I2 and the chassis ground.
