seconds.
2) Confirm that the firm contact is secured
between the airbag control module and con-
nector (AB6).
2
CHECK AIRBAG MAIN HARNESS.
1) Remove the instrument panel lower cover
and disconnect the connectors (AB7) and
(AB2).
2) Remove the instrument panel side cover on
passenger's side and disconnect the connec-
tors (AB10) and (AB9).
3) Disconnect the connector (AB6) from air-
bag control module, and connect the connector
(1U) in the test harness U.
4) Connect the battery ground cable and turn
the ignition switch to ON.
5) Connect the connectors (7U) and (8U) in
the test harness U.
NOTE:
After defective has been eliminated, disconnect
the connectors (7U) and (8U).

CHECK GROUND CIRCUIT.
1) Turn the ignition switch OFF, disconnect the
battery ground cable, and wait more than 20
seconds.
2) Disconnect the connector (AB6) from air-
bag control module.
3) Connect the connector (1U) in the test har-
ness U to body harness connector (AB6).
4) Measure the resistance between connector
(2U) in the test harness U and chassis ground.
Connector & terminal
(2U) No. 10 — Chassis ground:
(2U) No. 11 — Chassis ground:
4
CHECK AIRBAG MAIN HARNESS AND
BODY HARNESS.
1) Disconnect the connectors (7U) and (8U).
2) Remove the combination meter.
3) Measure the resistance between connector
(i10) and connector (2U) in the test harness U.
Connector & terminal
(2U) No. 7 — (i10) No. 13:
5
CHECK POOR CONTACT IN CONNECTORS
(AB1) AND (B31).
1) Turn the ignition switch OFF, disconnect the
battery ground terminal, and wait more than 20
seconds.
2) Confirm that firm contact is secured
between connectors (AB1) and (B31).
