The airbag controller is called the Sensing Diagnostic Module (SDM) and it senses a change in resistance in the circuitry for the seat mounted side airbag. Any change in resistance will cause a trouble code to set. The change in resistance can be temporary or permanent. Even though a resistance related trouble code is set and the airbag light on, the airbags will still work in a crash.
