DIAGNOSTIC CHART WITH DIAGNOSTIC TROUBLE CODE (DTC)
Step
1 CHECK FRONT SUB-SENSOR (RH) AND
FRONT SUB-SENSOR HARNESS (RH).
1) Turn the ignition switch OFF, disconnect
the battery ground cable, and wait more
than 20 seconds.
2) Disconnect the connector (AB6) from the
airbag control module , and connect the
connector (1I) in test harness I2. <Ref. to
AB-17, Airbag Control Module.>
3) Measure the resistance of the connector
(3I) in test harness I2.
Connector & terminal
(3I) No. 2 — No. 4:
Is the measured value within the specified
range?
2 CHECK FRONT SUB-SENSOR (RH) AND
FRONT SUB-SENSOR HARNESS (RH).
Measure the resistance between connector
(3I) in test harness I2 and the chassis ground.
Connector & terminal
(3I) No. 2 — Chassis ground:
(3I) No. 4 — Chassis ground:
Does the measured value exceed the specified
value?
3 CHECK AIRBAG MAIN HARNESS AND
FRONT SUB-SENSOR HARNESS (RH).
1) Disconnect connector (AB16) from the
front sub-sensor. <Ref. to AB-20, Front
Sub Sensor.>
2) Connect connector (IH) in test harness H to
connector (AB16).
3) Measure the resistance between connector
(3I) in test harness I2 and connector (3H) in
test harness H.
Connector & terminal
(3I) No. 2 — (3H) No. 5:
(3I) No. 4 — (3H) No. 6:
Is the measured value less than the speci-
fied value?
4 CHECK AIRBAG MAIN HARNESS AND
FRONT SUB-SENSOR HARNESS (RH).
Measure the resistance between connector
(3I) in test harness I2 and the chassis ground.
Connector & terminal
(3I) No. 2 — Chassis ground:
(3I) No. 4 — Chassis ground:
Does the measured value exceed the specified
value?
