Rear sonar system works backwards

Has anyone else that has the sonar system had this problem?

I put the vehicle in reverse in an open parking lot and the alarm goes off.

I put it in reverse in my garage and it doesn't.

I put it in reverse to parallel park and I don't get any tones.

It seems as if it is working backwards (no pun intended) and only goes off when there is nothing behind me.

Thoughts? Suggestions, other than to take it in and have them look at it?

I was hoping it would have been something simple like that so I did check the off button. No luck. I'll probably have them check it out soon.
mtbendo, You're not the only one...mine doesn't work at all either. I've checked both the fuses and even did the diagnostic test, which I did get the buzzer but no error codes. I'm assuming something is just not plugged in but haven't taken it back to a dealer to look at it.
mtbendo, sorry to read your other post about getting hit...some people just shouldn't have a license. But on the bright side, you could always take your truck back to the dealer and have some fun. Walk in, ask to talk to the sales manger, have him look at your truck. When he sees the damage, say "I thought this F'ing thing was supposed to have a rear sonar system, I went to back up the other day, checked behind me and couldn't see the other car over the tailgate. Well assuming this POS sonar was working, I backed up and now look at my brand new truck!!!" Throw an old set of keys across the room and ask what he's going to do about it...Then as he's giving you that, oh sh!t look, tell him you're just F'ing with him but the sonar never did work and you want it fixed once the bummer is replaced. Ask him to throw in some Titan shirt or something for brighting his day :teethmast
awgriffey, any idea where the connection was that they plugged in?
