Airbag Light Clock spring and Passenger occupancy sensor module?

I went into the dealership to fix a broken clock spring on my car, as it is causing the airbag light to be on, and the steering wheel controls do not work. When I brought it in, they ran diagnostics and said they could fix the clock spring, but that they found that the passenger occupancy sensor module was faulty and in order to remove the airbag light I would also have to fix that. My confusion is that it seems to be working perfectly and has since I bought it. Whenever a person (or heavy object) is in the front passenger seat, it detects it and if they aren't buckled the seatbelt light and beeps will come on until they buckle. This is still the case even since I left the dealership. I am trying to figure out if the module can work correctly like that, yet it also be causing the airbag light issue as they are telling me. I don't know if maybe they were getting an incorrect error code reading or something, or if it can just be cleared.
