AIRBAG SYSTEM (DIAGNOSTIC)
Diagnostic Procedure with Diagnostic Trouble Code (DTC)
X: DTC 66
DIAGNOSIS:
Seat belt pretensioner circuit (LH) is shorted to the power supply.
Pretensioner is faulty.
Pretensioner harness 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 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 side airbag harness, disconnect the side airbag module connector and seat
belt pretensioner connector for the safety reasons.
