AIRBAG SYSTEM (DIAGNOSTICS)
AR:DTC 76 PASSENGER'S AIRBAG FAILURE
DTC DETECTING CONDITION:
•Airbag main harness circuit (Passenger's side) is shorted to power supply.
•Airbag module harness circuit (Passenger's side) is shorted to power supply.
•Passenger's airbag module 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 main harness, disconnect the airbag module connectors and seat belt
pretensioners of the driver’s and passenger’s seats for safety reasons.
