ParkSense Unavailable message

[SBJT54]

Has anyone had this happen?....So just did a rear bumper swap about a month ago to the RR HD bumper and after 2 weeks of getting false readings on the right rear parking sensor now the system will not turn on and I am getting the below message. I replaced the sensor and still nothing. Any help or direction on where to start to trouble shooting from here is much appreciated.

I had a similar message and it was a problem with the wiring harness.

Check your entire wiring harness and make sure NONE of the wires are pinched.

It is quite easy to get a wire into a pinch point when tightening down the bumper.

So finally received the back ordered harness and still not working.... Someone outside the forum suggested have the dealer re-flash.

Apologies that I keep reviving this... I replaced the whole harness in the bumper and checked every wire that nothing is pinched....

So I finally caved... bought a scan tool and I am getting the following message.

Does anyone know where the ground is for this system or best course of action to fix?

Did you ever get this figured out? I am having a similar issue and a new harness hasn't fixed the issue.
