Fuse location

I have a facelift disco 2 ES with the rear parking sensors and since buying it the sensors and reverse lights have not worked.

The switch in the binical lights up, the sensors click as the should but no beeping or reverse lights.

Have searched without any joy for a fix.

Today I took apart the plug into the ecu and checked live feed and nothing there.

I am confused as I thought that would feed power to sensors and according to the manual the switch.

I also can't find the fuse. The nearest I can find out is brake lights and reverse lights on same fuse but brake lights are fine.

Anything else I can try and can someone tell me where the fuse is?

Cheers.

check the reverse light switch cos it's involved in the PDC management too, tyhe PDC will not work as long as the revers lights are not... to tell you more i need to know if it's auto or manual but i presume it's manual cos the reverse contact in the XYZ switch should have caused other issues too

It's an auto. No lights on dash to show any issues and display is showing R in reverse when it should.

I did wonder if that switch was part of the problem. I did find the ecu was getting power after rechecking.
