Parking sensors not activating

[Elvis222]

Hello,

I was troubleshooting a fault my usb & aux ports and after checking all the fuses for it my parking sensors stopped working. They were working perfectly fine before it.

When you put the car into reverse nothing happens like they are not activating at all, pressing parking assist button doesn't do anything as well.

I have gone back and checked the fuses again, all seems to be fine. Would pulling out fuses trigger a fault which needs to be reset with obd scanner? Is there any way on reseting parking assist system ( I did try disconnecting the battery for 10-15min).
