AIRBAG SYSTEM (DIAGNOSTICS)
2. MODEL WITHOUT CURTAIN AIRBAG
Step
1
CHECK SEAT BELT PRETENSIONER.
1) Turn the ignition switch OFF, disconnect the
battery ground cable, and wait more than 20
seconds.
2) Disconnect the connector (AB26) from seat
belt pretensioner (RH).
3) Connect the connector (1N) in the test har-
ness N to the connector (AB26).
4) Connect the airbag resistor to connector
(2N) in the test harness N.
5) Connect the battery ground cable and turn
the ignition switch to ON.
2
CHECK AIRBAG REAR HARNESS (PRE-
TENSIONER HARNESS RH).
1) Turn the ignition switch OFF, disconnect the
battery ground cable, and wait more than 20
seconds.
2) Disconnect the airbag resistor from test
harness.
3) Disconnect the connectors (AB17) and
(AB18) from airbag control module.
4) Connect the connector (1R) in the test har-
ness R to connector (AB18).
5) Measure the resistance between connector
(3R) in the test harness R and connector (2N)
in the test harness N.

CHECK AIRBAG REAR HARNESS (PRE-
TENSIONER HARNESS RH).
Measure the resistance between connector
(3R) terminals in the test harness R.
Connector & terminal
(3R) No. 19 — (3R) No. 17:
4
CHECK AIRBAG REAR HARNESS (PRE-
TENSIONER HARNESS RH).
Measure the resistance between connector
(3R) in the test harness R and chassis ground.
Connector & terminal
(3R) No. 17 — Chassis ground:
(3R) No. 19 — Chassis ground:
