Parking sensors playing up
 

The parking sensors in my 2012 GC have started playing up, Sometimes they work and sometimes they don't. It could go for weeks with no sensors and then one day you would be parking and for no apparent reason they would work, then a few hours/days or weeks later they would just stop.
Have toggled the on/off button on the dash and also the on/off options in the menu. But they continue to have a mind of their own and work whenever they feel like it.

Anyone else experienced anything like this, or have any idea how to fix this issue.

Spray a bit of wd40 into them. On the odd occasion inturn mine on I need to do this, water gets into them and mucks them up

I have had it where one intermittently shorts out an the control module parks the whole system and then when it un f's itself the module restarts the system. Alfa usually tells you which sensor it is that logged the code.

I've also had it where the reverse ones where operating intermittently then stopped altogether along with the reverse camera and that time it was the module.

will use the alpha to see which sensor is playing up.

Anyone able to tell me Where can I find in the AlphaOBD do I find how to check the parking sensors.

OK,
Got back onto this problem again today.
Have done a bit of research and it seems a comon problem is a plug in the back left hand corner which connects the park sensors to the rear bumper, it can get alot of water and muck up in there which has caused a few problems for people on other forums.
So i took the rear bumper off and pulled the plug apart, but it was pretty good in there and no sign of any corossion.
So i then decided would turn my attention to the front bumper assembly as i presumed it would have a similar type plug. I eventually found this in the front right hand corner, as I was looking at it I noticed the the little red clip that slides back and forward to lock and open the plug was in the open position. So as i reached up to get the plug it basically fell apart in my hand, I sprayed some contact cleaner in around it stuck it back together and pushed the red clip home and Presto the park sensors are working again.
Obviusly some lazy mechanic couldn't be fucked sliding the red button home and it eventually wiggled it's way loose.

Glad you sorted it out. Good job!
