Parking Sensor Constant Tone
« on: 22 April 2019, 19:13:44 »
Getting constant tone on rear sensors, had been a bit temperamental for a while. Usually a nice light 'tap/smack' on each sensor fixed the problem, done a bit of diagnosis this time.

I can hear the clicking on each sensor, so I think it's an obstruction. Best to remove each sensor from the housing, clean the tube and re-fit?  :-\

Maybe  :-\

I read before trick was either feel for tap or listen for the click, someones it's clear which sensor is not working. But they all are, as far as I can tell.

So junk/bumper dirt stopping on working correctly.  :-\

Entwood was No 1 for this ... something to do with a jumper in the box of electrickery in the boot seems to ring a bell  :-\

Thanks for that, a scan, suggests if I pull:

Entwood: What I did find was a purple blade fuse.. that isn't a fuse .. its a 430 Ohm resistor .. If I remove THAT and try the system .. the tones are different. I don't get the light "self test" tone at all .. I then get

That purple blade fuse, pops it into a test mode.

Where is said fuse though?  :-\

The Park Pilot ECU itself is, but I seem to recall the "fuse"/link is nearer the rear light cluster

Problem solved, fixed itself, for now at least. Got into car today, sensors working normally again.
