AIRBAG SYSTEM (DIAGNOSTIC)
Diagnostic Procedure with Diagnostic Trouble Code (DTC)
I: DTC 25
DIAGNOSIS:
 Airbag control module is faulty.
 Airbag main harness circuit is open.
 Fuse No. 6 (in joint box) is blown.
 Body harness circuit is open.
CAUTION:
 Before diagnosing the airbag system, be sure to turn the ignition switch to OFF, disconnect the
ground cable from battery, and wait more than 20 seconds before starting to work.
 After replacing the airbag module, seat belt pretensioner, roll connector, control module or sensor,
reconnect each part and confirm that the airbag warning light operates properly.
 When inspecting the airbag main harness, disconnect the driver’s airbag module and passenger’s
airbag module connectors for safety reasons.

AIRBAG SYSTEM (DIAGNOSTIC)
Diagnostic Procedure with Diagnostic Trouble Code (DTC)
Step Check Yes No
1 CHECK AIRBAG CONTROL MODULE.
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait more than
20 seconds.
2) Disconnect the connector (AB3) from air-
bag control module. Control Module.>
3) Connect the connector (1R) in test harness
R to connector (AB3).
4) Connect the battery ground cable, and turn
the ignition switch to ON.
5) Measure the voltage between the connec-
tor (2R) in test harness R and the chassis
ground.
