Seatbelt/airbag lights on??

So I just got home from a 3 week trip where my truck was started only once. I have OVTune 2.0 and I noticed that the passenger airbag light was on and the seatbelt light was blinking but no noise. Both seatbelts were fully clicked in and my gf was in the passenger seat. Anyone know why this would be doing this? I did I stall a sound system where I removed the driver seat multiple times. That’s all I can think of. I have no clue y this would be doing this. Any help appreciated

 

Since the only significant thing you did was removing the Seat several times, I would narrow it down to the seat wiring harness which may not have been seated properly. That’s all I can think of.
