J: DTC 26 PASSENGER'S AIRBAG INDICATOR FAILURE
DTC DETECTING CONDITION:
•Passenger's seat airbag indicator is faulty.
•Airbag control module is faulty.
•Airbag main harness circuit is open.
•Body harness circuit is open.
CAUTION:
•Before diagnosing the airbag system, be sure to turn the ignition switch to OFF, disconnect the
ground terminal from battery, and wait more than 20 seconds before starting to work.
•After replacing the airbag module, seat belt pretensioner, roll connector, control module and sen-

K: DTC 27 ODS COMMUNICATION ERROR
DTC DETECTING CONDITION:
•Occupant detection control module communication is faulty.
•Airbag rear harness circuit is open, shorted, shorted to ground or shorted to power supply.
•Occupant detection harness (seat harness) is faulty.
•Occupant detection system is faulty.
•Airbag control module is faulty.
Step Check Yes No
1CHECK POOR CONTACT OF CONNEC-
TORS.
Check for poor contact of the connectors
between the airbag control module and the
occupant detection control module.
Is there poor contact? Reconnect the
connector. If
defective is not
improved, replace
the airbag rear
harness RH or the
occupant detection
harness (seat har-
ness).
Go to step 2.
2CHECK THE AIRBAG HARNESS.
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait more than
20 seconds.
2) Disconnect the connector (AB18) from air-
bag control module.
3) Disconnect the connectors (AB59) and
(AB61) under the passenger's seat.
4) Connect the connector (1U) in the test har-
ness U to connector (AB18).
5) Connect the connector (1AB) in the test
harness AB to the connector (AB61).
6) Measure the resistance between connector
(3U) in the test harness U and connector (2AB)
in the test harness AB.
Connector & terminal
(3U) No. 2 — (2AB) No. 1:
(3U) No. 4 — (2AB) No. 2:
Is the resistance less than 10
Ω?
Go to step 3.Replace the airbag
rear harness RH
with body harness.
3CHECK THE AIRBAG HARNESS.
Measure the resistance between connector
(3U) in the test harness U and chassis ground.
Connector & terminal
(3U) No. 2 — Chassis ground:
(3U) No. 2 — (3U) No.4:
Is the resistance less than 10
Ω?
Go to step 4.Replace the airbag
rear harness RH
with the body har-
ness.
4CHECK THE AIRBAG HARNESS.
1) Turn the ignition switch to ON.
2) Measure the voltage between connector
(2AB) in the test harness AB and chassis
ground.
Connector & terminal
(2AB) No. 3 — chassis ground:
Is the voltage more than 9 V? Go to step 5.Check the battery
voltage and fuse. If
there is no faulty,
replace the airbag
rear harness RH
with body harness.

CAUTION:
•Before diagnosing the airbag system, be sure to turn the ignition switch to OFF, disconnect the
ground terminal from battery, and wait more than 20 seconds before starting to work.
•After replacing the airbag module, seat belt pretensioner, roll connector, control module and sen-
sor, reconnect each part and confirm that the warning light operates properly.
•When inspecting the airbag main harness, disconnect the airbag module connectors and seat belt
pretensioners of the driver’s and passenger’s seats for safety reasons.
