NOx controller does not receive 12V.

1. I cannot find fuse. Is it possible that only FL models has fuse for Oxygen and NOx controller?

2. Where is second end of ws/ro ? Cannot find any diagram... 😞

 

The line you are on is 186, so the ws/ro 53 you will need to go back a few pages to find the numbers along the bottom to find 53.

 

Hopefully that makes sense to you now.

Take a look here for some guidance from several members.

 

 

I think I found it.

Fuse SB9, am I correct?

Yes that's where it tracks back to, and colour of wire is same.

Thank you. It was dead fuse. No controller receives power.

 

No I have error P1072 NOx sensor heating

Ok, so the fuse died for a reason then.

Did you mean *Now* realise you cannot edit post just yet (reach 10 iirc and you will be able for 1hr fix spelling mistakes)

Have you got the full log of the error?  Maybe you need to track every wire going to/from it to check for any shorts or broken wires.
