Service Airbag Notification

[Bowtie619]

Hey guys,

 

I'm getting this notification on two occasions but intermittent. The first is when someone sits in the rear back right seat or even sometimes if I set something heavy on that rear back seat. The other is also tied to the rear right seat but sometimes alerts the moment they pull the right rear seat belt. 

 

Can anyone advise whatight be triggering this and which items I troubleshoot before starting to dig in back there? Thank you!
