Rebuilt ecosport airbag light won't turn off

The ecosport I bought at the auction had front end damage, the driver and passenger knee airbags deployed. Also both seatbelts were locked. I bought the airbags from a junkyard and the seatbelts and modules got sent to Safety Restore. I put everything back together and the airbag light turns off for like 3 seconds than comes on. The Fordpass app alerts me that there is a fault in the circuit with the driver and passenger knee airbag, seatbelts, and front sensors. What does this mean i thought that once you connected it back together it would all work out just fine.? Any idea as to how to fix these problems.
