Factory fitted reversing sensors

[Lewis1988]

Hi all
Does any body know how the factory fitted reversing sensory are wired in

And how they are switched on and off

I know the aftermarket mods are wired using the reverse live cable.

I may be wrong but I think they are wired in through Canbus.

Don't think you can switch them off but you can mute the sound using a setting on the head unit.

So I have started stripping down looking for he fault

Found a box in the right hand corner of the boot which when disconnected stop the reversing sensor beeping

Sensor for the reverse signal is on the gearbox i think.

Internal on the Gear shift or external on the g/box ?

[Roy_01]

On golf 4 the reverse sensor was fitted on the topside of the gearbox in the engine bay. But is your reverse lights coming on while driving forward? Or do you have a continous beep only when you are reversing? Then i could be a faulty sensor. First scan it with vcds to search for errors.

Sounds like your reverse switch is kaput. I was reading your other post about it here http://www.sciroccocentral.co.uk/forum/ ... 99#p169099" onclick="window.open(this.href);return false;

Or something is shorted/bad ground.

Don't think a faulty reverse switch would give the intermittent fault ... Think it's more like a short between cable and car body somewhere

Question for an electrician

if I take the electrical connector of the reversing switch can I con check pin to pin in the connector to check the integrity of the wires ??????
