Think Entwood was going to have a look at it at Newent, but rain may have stopped play this (sun)morning....?

[Entwood]

Yup .. rain certainly stopped play today !!! As did some serious tracking adjustment to make the car safe to drive !!  So no closer to solving my problem

The 3 x 1 sec bleeps say the ECU is not getting the correct signal from the #3 sensor as you state.  Does the #3 sensor vibrate if touched VERY lightly with a finger ?? If it does then try swapping it to another position and see if the fault moves with it !! If it does .. sensor problem .. if it doesn't, possibly wiring fault 


Beside the red 430 Ohm resistor should be a male/female spade pair, one black wire, one black/white wire. If these are connected the system is in "quiet" mode, if apart, "loud" mode.

the 430 ohm resistor is blue - is the correct Bosch resistor supposed to have a particular colour?

No idea to be honest .. the two I have are both red ..  :-/ :-/

The initial problems were that the error only occured after the car had been standing overnight in rain. Once driven for 15 minutes, or left dry .. the system worked fine.

I have factory fit front and rear park pilot, when it rains i get the single long tone from the rear.

I did 'wipe' the sensors one day and without knowing slightly moved one of the sensors, kept getting a long tone in reverse. Took bumper off clipped it back in and all good.

Just maybe a bit of a long shot but perhaps they are not sitting right hence the issues and moving the fault up and down the line?

Nice thought and thanks .. but I've tried with all the sensors out of the bumper, inserted into boxes with holes cut to ensure that NOTHING is within the sensor range, and still the fault moves around ...

Next plan is to "rewire" the loom temporarily - basically bypasing existing wiring and see what occurs.. but that won't be done this week due to other committments ..

[pscocoa]

Look forward to feedback - will take bumper off when I can but likely to be travelling next 3 weekends so will now be October before I have time I suspect.

[Kait]

Any luck with parkpilot so far?

[Entwood]

Unfortunately due to a combination of family circumstances/weather and a few other things ... no work has been done on this at all. It is pretty low priority TBH, and certainly won't be touched until next year now.

Resurrecting a pretty old thread ....

Thanks to Albs who has provided a new control box and loom things are making slow but significant progress.

Still have a problem .. but it is now isolated to one sensor, if I move the sensor around all wires work but that one sensor does not .. no matter where placed.

I've even put the old loom/control back in...'cos I could ... and the fault again becomes random, indicating a fault with the loom and the control box.

On removing the faulty sensor .. I found it like this .. on the side I could not see !!





Now that is a CUT not a crack, initially, although it has spread to a crack around the back. How or what has done that I've no idea.

As the problem started 3 months after the car went in to have the accident damage repaired, I'm wondering if they tried to cut the sensor out to do the respray. I also think they have "stretched" the loom and damaged it. Perhaps water has got into that sensor and shorted it, so causing damage to the control box

However .. advert going in the wanted area for a sensor .. once I get one we'll see what happens next ..

[albitz]

So, it has almost sorted your problem Nige ?

It's made a big difference !!!  Fault is no longer random .. but I do have one sensor proved faulty.. so looking for a replacement.   Won't ask you to split your set off the bumper .. might make selling the bumper a tad harder ..

I'll probably PM AndyC and see how much a new one is as well ..

Thanks for your efforts and help .. appreciated... 

[albitz]

Happy to help (to an extent) Nige.

Goidelic news 

[Entwood]

In the absence of getting a used sensor .. purchased one from AndyC - excellent service yet again .. ordered Thursday it arrived this moring !! - many thanks to him.

Just finished putting the bumper back on .. again ... and am pleased to report that the system, apparently, now works as it was designed ..... at last !!

So since the numpties who did the accident damage repair did their best (although it didn't fail until 3 months after their ministrations) and apparently used an angle grinder to remove the sensors ....     it has only taken

3 x Sensors
2 x Sensor Holders
1 x Control Box
1 x Replacement Loom

to get it back to as it should be.

A mate who just loves playing with electronic things has had a play with the sensor with the cut in it, the old loom, and the control box .... he says the sensor was very wet inside and the control box chips don't make any sense when tested (whatever that means !!). He thinks that the water inside the sensor has caused the chips to fail over the long term. There is also a "discrepancy" in the resistance of the different legs in the old loom.

He also thinks I could have saved both the other sensors and the control box if I had unplugged the whole system .... all I had unplugged was the speaker ... so electrickery has been getting to the wrong bits for some considerable time .... like about 17 months !!! since it was first damaged !!!


Anyway ..'tis now sorted thanks to AndyC, Albs, and the advice recieved from various folks on OOF .....  Thanks to all of you
