Reversing aid fault

David Lawrence · 1st March 2009, 19:08

My 2001CDT Conn SE, has recently exhibited a high pitched continuous tone squeal on occasion when reversing.

When it does this, it is a squeal at about twice the frequency of the normal continuous tone you get when you've reached an obstruction. and subsequent operations of the reverse gear fail to re-start it, although it had started OK with the single bleep sound before the fault happened

Anyone know what's the cause. At present the problem is only intermittent, but I dare say it is a sign of something on the way out.

Hi, mine did this and I took off rear bumper to find a broken wire at the plug. I just spliced the said wire and soldered it, then put a heat shrink sleeve on and wrapped it in tape. Everything now works as it should. uniblue

Plenty of threads on this, do a search

Bur the problem is usually easily found with a visual inspection (as in my case)

And resolved

However one of the sensors could be mal-functioning. Get someone to place the car in reverse (engine off!!) and listen to the sensors in turn. If working you should hear a "clicking" sound from each one.

Hope this helps
