mrchic Posted December 20, 2012 Share Posted December 20, 2012 My parking sensors are knackered, constant annoying beeping as soon as you put in reverse. Was told by a mechanic at a recent check that the harness had melted to the exhaust. i didn't go into much detail about fixing it as the car was in for other stuff. Can i access any of the wiring from the boot area, or would it need jacking up. Id rather not jack it up,as i don't have ramps or stands.and its on gravel. I've seen some kits on Ebay for about £20. Do you think i could do this my self. Thanks James Quote Link to comment Share on other sites More sharing options...
glrnet Posted December 20, 2012 Share Posted December 20, 2012 Sounds like a bodge installation job. If cables are melted to the zorst that's where your problem lies I'm afraid you're going to have to jack it or reverse up onto a couple of planks or wood which might give you enough room to slide under. Good luck The control unit is probably under the false floor in the boot, try and identify the manufacturer and see if you can get spare sensor cables 1 Quote Link to comment Share on other sites More sharing options...
mrchic Posted December 20, 2012 Author Share Posted December 20, 2012 Thanks I'll take a look I'm hoping in the mean time i can just unplug it to stop the noise Quote Link to comment Share on other sites More sharing options...

glrnet Posted December 20, 2012 Share Posted December 20, 2012 Most units have five plugs, one for the power and earth and four for the sensors, a process of elimination will identify your faulty one, turn ignition on put car in reverse to produce noise and remove sensor plugs one at a time until noise stops.

scubapics Posted December 20, 2012 Share Posted December 20, 2012 Mega bodge job! The cables should have been passed through the rear bulkhead with the reversing lamp cables. Bumper off job to do it properly. Quote Link to comment Share on other sites More sharing options...
rabbitstew Posted December 20, 2012 Share Posted December 20, 2012 These are pretty easy to fit yourself, my mate who knows nothing about car electrics at all managed to fit one on his car earlier in the year! 1 Quote Link to comment Share on other sites More sharing options...
Spoony Posted December 26, 2012 Share Posted December 26, 2012 Are the surfaces all clean? not laered up with polish or something silly? Quote Link to comment Share on other sites More sharing options...
mrchic Posted December 27, 2012 Author Share Posted December 27, 2012 Are the surfaces all clean? not laered up with polish or something silly? That's a good idea to check those too, I'll give them a clean with some detail spray and a cotton bud or something. Quote Link to comment Share on other sites More sharing options...
glrnet Posted December 27, 2012 Share Posted December 27, 2012 Just use mild soapy water and a soft detailing brush 1 Quote Link to comment Share on other sites More sharing options...

Had a look this morning under the floor in the boot, discovered what can only be the control unit. Its a Nissan part with a connector plug on top. Bit of a noob question but i wanted to remove the foam bracket which holds the jack and tools to trace the sensor cables. i have seen two plugs which hold it down, but do i need to remove any of the other trim as sliding it out is somewhat tricky. Or do i need to be more forceful Thanks Quote Link to comment Share on other sites More sharing options...
scubapics Posted January 8, 2013 Share Posted January 8, 2013 From memory you need to remove the trim. The "Nissan" box could be the amplifier for the audio system as that is mounted in the boot AT&T the very rear left of the car - again from memory.

un1eash Posted January 9, 2013 Share Posted January 9, 2013 It's unlikely to be a Nissan part for the sensors as they were dealer fit. The control unit is usually in that area though as it takes power from the reverse light. With the car in reverse feel each sensor with your fingers, when working correctly you should feel them clicking/pulsing. I replace my whole kit with a £18 one from ebay when one of the sensors failed. It's a bumper off job but there's a decent guide online on how to do it. Getting the foam out from the boot takes a bit of force due to its shape. Quote Link to comment Share on other sites More sharing options...

Thanks Ill going to take a closer look over the weekend, the Nissan part mentioned looked like a typical siren, so this maybe the alarm? Having looked at the actual sensors, they got a few marks around the holes, so not a great job. Ill get some images up soon, and as mentioned before i need to either get underneath/ take bumper off the car. Ps Noticed your sig and the Audio setup, have you got a thread on here with the install/pics. I would like to upgrade at some point, and ive got some SPL dynamics 6.5 components to use Thanks Quote Link to comment Share on other sites More sharing options...
