Terios 2009 parking sensors issue

Forum: 

Irritating beeping all the time even if there's nothing around the car day or night
No switches to turn them off
No damage to the bumper or out of shape sensors
Cleaned the sensors even with wd40 and problem is still there
I can use a wire cutter and shut them all off but I thought I would ask here first
If this problem not solved I will drive the car down a cliff and end it's and my life
