Is there any way to dissconnect front sensors, and have the rear ones running, or other way around ?

The thing is that i have pdc error, all my sensors make sounds, so i am trying to limit the search to front or reare.

I have a trailer hitch, will it help if i connect it ?, reare one should not work then ?
