Couple Beeps in Reverse

[G_Greenway]

Hey everyone. I’m new to this forum. I have a 2020 3500, Cummins HO with the Aisin tranny. Quick question. I don’t have a back up alarm, or Park Assist (sensors). However, when I go in reverse, I’ll occasionally get an alert - it’s usually 2 beeps - nothing more. Nothing comes up on the screen, so I haven’t pin pointed what exactly is causing this. Maybe it’s an alert, or maybe it’s a glitch. Thoughts?

If you had park assist sensors, it would say you were going too fast and the sensors were temporarily disabled.

Reverse, cross path detection would be my guess, based on my understanding of what you’re describing.

If you have blind spot monitoring, then that is the cross path detection alert. The sound will favor the side of the vehicle the car or pedestrian is approaching from, and the the indicator in the mirror on the approach side will flash.
