DS3 airbag fault

[Stevo165]

Hi, looking for some help with a friend's DS3. I have code read the car because the airbag light is on and its saying it has a pretensioner/airbag fault on the dashboard display. There are 2 fault codes coming up C610+C611 rear right and left satellite faults. It's a hard fault that can't be reset. Has anybody come across this fault before?

Quick update incase someone else has this problem in the future. Car is now fixed. Replaced both sensors.....not easy as they are located underneath the drivers and passenger seat belt reels. Reset the fault codes after changing sensors and all good.
