DIAGNOSTIC PROCEDURE WITH DIAGNOSTIC TROUBLE CODE (DTC)
AIRBAG SYSTEM (DIAGNOSTICS)
Step
7 CHECK FRONT SUB-SENSOR HARNESS
(LH).
1)Connect the connector (2F) in test harness F
to connector (AB14).
2)Measure the resistance between connector
(3H) in test harness H and connector (3F) in
test harness F.
Connector & terminal
(3F) No. 5 — (3H) No. 5:
(3F) No. 6 — (3H) No. 6:
8 CHECK FRONT SUB-SENSOR HARNESS
(LH).
Measure the resistance between connector
(3F) in test harness F and the chassis ground.
Connector & terminal
(3F) No. 5 — Chassis ground:
(3F) No. 6 — Chassis ground:
9 CHECK FRONT SUB-SENSOR (LH).
1)Connect the connector (2H) in test harness
H to front sub-sensor (LH).
2)Measure the resistance of the connector
(3H) in test harness H.
Connector & terminal
(3H) No. 3 — (3H) No. 4:
10 CHECK FRONT SUB-SENSOR (LH).
Measure the resistance between connector
(3H) in test harness H and the chassis ground.
Connector & terminal
(3H) No. 3 — Chassis ground:
(3H) No. 4 — Chassis ground:
Check
Is the resistance less than 10
Ω?
Is the resistance more than 1
MΩ?
Is the resistance 750 Ω — 1
kΩ?
Is the resistance more than 1
MΩ?
