08 Yaris, Passenger airbag off with seat belt light blink

Thanks for the prompt reply. I will give it a check at noon when it is not freezing cold outside. It is -34 C, and -50 C with windchill in Winnipeg.

I just used OBDII scanner and found no error code but the airbag warning light is solid on in the cluster panel.

OBDII can only read engine codes. You would need a Toyota specific scanner to read the SRS codes.

Thank you CTScott! The problem is gone.
When I check the two connectors on the passenger occupancy classification ECU (underneath the Passenger seat), the bigger was a tiny bit of loose. When I push it in a little bit I hear a click sound. Then the problem solved.
Thanks for the accurate diagnosis and prompt advices!
