The backup camera on my 2012 Tahoe is coming on in park and when I'm driving down the road. The backup camera screen is located in the rear view mirror. I have noticed when the camera turns off a small light blinks on the bottom of the rear view mirror below the mirror dim power switch.

Do you know why the camera is coming on when the truck is not in reverse?

Thanks!

 

maybe a bad input from the trans range switch....check engine light on?

 

No, the check engine light is not coming on.
