Fiesta 2008 (Mk V) Reg reversing sensor fault

[Redmondo]

Good afternoon, 

Our 2008 reg Fiesta (mk V) 1.4l automatic has reversing sensors fitted. They worked when we first got the car about a year and a half ago. They now seemed to have stopped working. Wondering if it could be a fuse but don't know which one it would be? 

Or could there be something else causing the fault?

There is no longer an audible sound when the car is putting into reverse. 

Any help is appreciated. 

Thanks

Are the Reversing lights coming on ?

Check Fuse 48 7.5A

If they were aftermarket the little sounder box has probably packed up or got disconnected
