AIRBAG SYSTEM (DIAGNOSTICS)
AS:DTC 91 CURTAIN AIRBAG MODULE RH FAILURE
DTC DETECTING CONDITION:
•Curtain airbag harness (RH) is faulty.
•Curtain airbag module (RH) is faulty.
•Airbag control module is faulty.
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 rear harness, disconnect the side airbag module connector, curtain
airbag module connector and seat belt pretensioner connector for safety reasons.

Step Check Yes No
1CHECK POOR CONTACT OF CONNEC-
TORS.
Check for poor contact of the connectors
between the airbag control module, curtain air-
bag module RH and the curtain airbag sensor
RH.
Is there poor contact? Replace the airbag
rear harness with
body harness.
Go to step 2.
2CHECK CURTAIN AIRBAG MODULE.
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait more than
20 seconds.
2) Disconnect the connector (AB33) from
(AB40), and connect the connector (1F) in test
harness F to connector (AB33).
3) Connect the airbag resistor to the connec-
tor (3F) of test harness F.
4) Connect the battery ground terminal and
turn the ignition switch to ON.

illuminate for 6 seconds and go
off?
Replace the cur-
tain airbag mod-
ule (RH).
