Pdc not working advice needed

[jamiecarpenter]

My PDC has stopped working. I've checked the fuse which is fine. I have looked at the module for any damage or water ingress and there isn't.

So I then decided to put it in reverse and try and hear the clicking noise. However I can't hear any clicking from any of them. Question I firstly have is how loud and how often should they click? Just in case I missing it or I'm slightly deaf.

I have bought a replacment sensor. If I can not identify the faulty one by listening to it, is it then the case of swapping each one out indvidually with the new one till they all work?

Any help would be much appreciated.

A decent code reader will be able to pinpoint which one has failed

Do you get any beeps at all from inside?
Not a long, annoying 'beeeeeeeeeeep' when selecting reverse?
Or just nothing?

Get the long 5 second beep then goes off.
