Thank you very much ill have a look, see if I can figure it out.

All the music and warning tones still work.
So I assume there are separate speakers for the pdc?

Yes. Reverse lights work. And sensors all.work it's just the beeper that's stopped. Not sure where the speakers are located to test them.

I'm not sure.
Does pdc have a separate speaker?
If so where would it be located?

Thanks

The beep sound for the pdc has stopped working. I have had a diagnosis and there was no fault. I have bought a new module and swapped and still nothing. I have had the sensors tested and they all work fine I just don't have any sound. I dont have the original head unit. I have a pioneer installed ...
