lexus ultrasonic backup sensor stopped making sound while backup

Spoiler

Hi guys, I came across an issue to my 2015 lexus is250 fsport. My car doesn't have the P button. I think because the car is not equipped with the Park Assist system which constantly beeps while backing up and approaching a stationary object. All it does is just beep when a moving object passes by from a distance. I installed a mirroring kit to my head unit, but didn't know if that caused my issue or it had existed before I installed the mirroring system, but I doubt how it will affect rear sensor by just daisy chaining a mirroring system on the head unit.
I checked the fuse box and didn't see blown fuse. (red mark)
My best bet is to remove the rear bumper and check the resistance and voltage of the sensor see if I need to replace.
Any other thoughts from you genius people?
