Airbag light won't go off after the car warms up if it's extremely cold.

Same problem. Under extremely cold (5 degrees F and below, the airbag light will come on and blink while the car is running. Drive for 15 or 20 minutes, turn the car off, restart it, and the light will go out.
Still looking for a correction although the dealer admits it is a known problem. There claim at the time was that there was NO recorded "code" to tell them exactly what it was!? At the time, we had extended warranty coverage. It happens every cold spell--about 10 degrees F and lower. It lasts about 1/2 hour and then the light finally shuts off. They won't say definitively whether we are in danger, or not, while the light is flashing.

The temp went down to -2 F and the car was parked outside for an hour and half. when I just started my car, the airbag light started flashing and did not go away. Again the next day morning when I started the car ( temp was still around -4 F), so the light keeps flashing. Called toyota dealer . They said it is 97 dollar for running diagnosis
