So a bit of guidance needed. Old problem, Parking sensors played up.
No sensors working , so disconnected plug feeding loom to front ones . Power and earth working . Both front and rear been fine for 10mths. According to GAP the rears. once the front is disconnected. are showing Activated and listened through stethoscope are all fine , ticking away, but no
sounder.


Had a look at other posts with the codes I got, but am I missing something.

Those are engine fault codes , not park sensor pdc

If you want to only use rear you need to edit the Ccf. Ensure battery well charged.

Yes I had trouble finding pictures as my broadband is not very fast. You should see the codes as I edited them . Gap does want to use other or both ends for sensors , but I have seen this before ate separate ends , perhaps on my Vogue, but the choice is Both only on GAP a the moment. Yes charging battery ...... again!

Probably one of the sensors failed at the front then.
It won’t tell you wish in this case

Not quite , 10 mths ago I used to be able to sus out what sensor let me down , and got them all working this way, I think I replaced at least three. Now nothing is showing , GAP not helping either. Just avoiding fr bumper off at the moment.

Edit the Ccf then to select only rear sensors fitted.

Hmm not getting the option on GAP. i'll have another look.

I have checked out the front sensors again and I found the resistance on one of the sensors was about 15-18 ohms more than the others , so fortunately its the sensor just below the headlight , thinking I had a new one I replaced it , but hasn't helped.

Has anyone noticed what resistance values in I should be getting , currently 10-12 ohms myself.

One with a lower resistance between black and brown wires is what u should be looking for I think

Pretty sure , while sitting inside and not confirming, I'm pretty sure they were the colours , so you reckon lower values or lowest value. I have ordered more sensors.

Thanks Andy for prompt to check out GAP, read it wrong, fronts now separated and rears working with resistance values around 10ohms except one at 9 , and assuming it takes that to put the system down which is unbelievable. I will have to remove the bumper to trial the different sensors and their wiring.

Ok stuck for the moment , where do I go, what do I do. I know not having parking aids is no biggy, but they are handy and they are there. I now can't get the back ones or the light on the dash to work now, it did work this morning with the rears only activated.
I have checked out all the loom to fronts all check out fine with sensors detached. Pulled all plugs on P module, everything dry.
So , what have I missed ccf has been left with front plug disconnected, no dash light and on rears only. I did check the power in this situation going to rears and voltage was there.but no lights on , if you know what I mean.

well read the fault codes, tell me what they are from park module.
clear them,
park brake off, into reverse. Then read codes again and tell me.

You could check the 5A fuse if you have lost comms and nothing is happening.
Did you get the beige plugs the wrong way round on ecu?


I guess you need to got over again, when you did when the rears stopped working

No codes reappearing , last thing I did was remove plugs from ecu ,problem had arrived before that. I’ll see in the morning , the battery is a tad low right now.I think if I saw right that the plugs are different between beige. More info tomorrow. Still doesn’t rule out why the fronts aren’t co-operating. Argh!!
Wondering if the sounder is an it regal part of the system causing a breakdown . As I remember the front sounder , wasn’t working , but still didn’t stop the whole system..... I think?

If the fronts aren’t plugged in they can’t be the problem.
If they are plugged in then that could be it, causing short
