Reverse sensors fault...

Hi all.

My friend reverse sensors intermittently have a constant long beep when there is nothing behind me.
Is it a case of ignition on, in reverse and listen for click?

Any thoughts, tips etc please?

Many thanks in advance.

Bazza.

Moisture ingress somewhere, either in one of the sensors or the PDC ECU can cause the system to sound randomly.
While the system is engaged, does the little orange tell-tale light on the switch on the binnacle flash or is it on steady?
Listening to each sensor in turn to hear if they're clicking is a quick way of deciding whether you have a fauilty sensor, and which one it is.

Sorry chaps. Had some it issues... Poxy phone.


The light on the switch stays on constantly.


So no clicking faulty sensor then mate?

Thank you for your reply.
