Airbag monitor malfunctioning - Toyota Yaris Forums

Hard_Yaris · 12-07-2010, 04:33 PM

Today when i started her up it was about -19C this morning.
the Airbag "ON" and "OFF" light for the first time was set to "OFF" then after it warmed up both on and off where not lit up. and continue to be this way.

The yaris manual basically says "Take it to a Toyota Dealership Imeditaly"

Ill keep an eye on it for the next couple days.

Has anyone had this problem?

Thanks.

That's actually a normal behavior. If there was an issue the airbag off light would stay on and the passenger seatbelt light would flash quickly.

You can verify that it is working correctly by sitting in the passenger seat and verifying that the airbag on light comes on.

Its working fine.
Im very sure the on light has always stayed on.
This is this first time i noticed that it turned to the off position when no one was in the seat.
Very Odd.

Based on my work with the passenger occupancy ECU, I think that the light going out has to do with the zero point calibration. It may be when the 4 occupancy classification sensor readings are less than the zero point that it turns the light off.
