What Are These Thingys On My Bumper?

[tmh1955]

Just purchased 2006 2500 Laramie last week. I notice there are 4 round sensor looking thingys on my rear bumper. I have been unable to find anything in the manual about them.



Is this some sort of back up sensor?

Sounds like it to me. Maybe aftermarket?

Try backing into something and see if the truck makes noises.

If you purchased it from the dealer. They may have removed the most important part of the Backup Unit.

They are proximity sensors. They are used to alert you of an object in your path while backing.



There is this guy that is in our weekly NASCAR pool that is a real pain in the but wise guy type we all know the kind. Anyways, I taped 2 pennies with electrical tape to 2 of the sensors on his brand new Cheby. Trimmed the tape real neatly so it was not very noticeable with out getting down for a closer look. His back up alarm would go off every time he would put it in reverse, so he calls the dealer and takes it in for warranty. Needless to say, after sitting in the waiting room for an hour or two ( he won't say ), the tech came out and told him, "You have some pretty good friends out there, don't you?" and showed him the pennies.

I thought that was pretty funny. Then I read,

"I taped 2 pennies with electrical tape to 2 of the sensors on his brand new Cheby"

I was thinking how funny taping the pennies would be, and the Karma hits and my wife's car just got backed into by someone who could really use that system... Damn...
