The gremlin could be any one or more of these: driver/steering wheel airbag, passenger on-dash airbag, left seatbelt airbag/sensor, right seatbetl airbag/sensor, left roof/curtain airbag, right roof/curtain airbag (if applicable).
You would need to use a professional quality scanner to read the airbag code (not elm 327 or regular innova, even not most actrons). It will tell you which airbag is failed. Parts and labor for r/r are expensive.
