Rear Parking Aid Sensor Issue After Car Wash – 2012 Mustang V6 premium

[Mr_Meow]

I recently washed my 2012 Mustang V6 Premium (S197), and right after that, the rear parking sensors stopped working completely.

I used to be able to turn them ON and OFF from the dash using a button that had a small arc symbol showing whether it's ON or OFF.

Now, that arc symbol no longer shows up, and the button doesn't respond or change anything.

Has anyone experienced something similar?

I'm wondering:

1. Is there a way to reset the parking sensor system manually?
2. Could water from the car wash have affected a specific sensor or fuse?
3. Where is the parking sensor control module located?
4. Any known fix or common issue with this on the 2011–2014 V6 Mustangs?

Thanks in advance for any help!
