Disco 2 rear fog light problem

Hell on my 2004 td5 I have no rear fog lights but the switch works and the Tel tail led comes on but no power to the bulb holders in the rear bumper . As this is a bcu system can anyone tell me where to go next please ?

I'm a bit lost .

one thing, if you plug a trailer plug in I believe it disables them.
second, page 102 in Rave manual.
If you haven't got it hopefully one of these links will help

The easyest seems to be the online version http://new.lrcat.com/ but if you want to print out here's the PDF of the book https://rimmerbros.com/images/pdfs/discovery2.pdf , a version without engine overhaul parts attached

The reason i put so many up is because they often stop working for some reason so I add one as soon as someone else puts a new one up.

I'm a bit lost with all those links etc .

when I bought mine it had a trailer plug on it and it's still on it and the fogs worked last MOT I haven't changed anything .

So what am I looking at ?

cheers

Sorry I put up so many, the one with the French in the middle will give you the whole RAVE manual, which includes all circuit diagrams.

what I should ask is what is my next things to check , I will study rave later but not great on schematic diagrams ... yes I know the switch switches the earth but then I'm guessing goes to bcu which then I'm lost what happens inside .

Hi, as long as the light works on the switch the electronic side is OK cos the feed for the led is splitted from the lamps circuit so the BCU and IDM are doing the job, you'll have to see if you get 12V against body at pin 8 of C0484/0102 (red/yellow trace wire) concentrate on the wire colours cos there are cases when it's in other pin, that plug used to suffer from corrosion. If you have 12V there we'll speak again

Thanks , I will check tomorrow after work , the light is starting to go .

cheers
