Z: DTC 45 SIDE AIRBAG RH FAILURE
DTC DETECTING CONDITION:
•Side airbag harness (RH) is shorted to power supply.
•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 main harness, disconnect the airbag module connectors of driver's
and passenger's seats for safety reasons.
•When inspecting the airbag rear harness, disconnect the side airbag module connector, curtain
airbag module connector and seat belt pretensioner connector for safety reasons.
