backup sensor problem
My 02PSD F250 has the backup sensors in the bumper. They haven't been working for awhile now but boy do I miss them in a tight spot.
What are the first things to look at to troubleshoot?

I personal tried the clicking test and got nothing. My seems to be related to my trailer harness. They start working for a while just after I have a trailer hooked up multiple times. I'm going to slide under when it gets nicer and clean all the wiring harness up. I have a bluetooth obd2 adapter and don't have any codes is their a specific test or software ?

Anything that's "wrong" in the system can cause it to go to OFF. For example, if the speaker is bad, or if there's a chafed wire anywhere, the system will go to OFF.
My last truck's system worked flawlessly. I ended up wiring a switch inline with the speaker wire so I could force it to stay OFF. It would become a real PITA while plowing or towing.
My current truck's back-up sensor will work every once in a while. I'm in no hurry to find the issue and fix it.

I already replaced the speaker. Speaker has 12V too it, when in reverse...which I would think means the module is working. All 4 sensors click, so they appear to be working too. Don't know what else to do.
