Lanos S Hatchback L4-1.6L DOHC D-TEC MFI (1999)
Malfunction Lamp / Indicator: Description and Operation
The supplemental inflatable restraints (SIR) system include a self-diagnostic function.
If there is a failure of the sensing and diagnostic module or the external circuits, the SIR warning lamp in the instrument cluster turns ON.
As a system check, the SIR warning lamp also turns ON when the ignition is first switched to the ON position.
Correct Functioning
The system is working properly if:
The SIR warning lamp turns OFF after approximately four seconds.
Faulty Functioning
The system is not working properly, meaning one of the SIR components or the wiring connector is faulty, if:
-
The SIR warning lamp fails to turn ON when the ignition is first switched ON.
-
The SIR warning lamp remains ON.
