I replaced my backup camera and now it is working without the error I kept getting. I am missing the backup sensor bricks. Not the lines but the on screen prompt that shows when you get close and they are the green, yellow, red prompts to show how close you are. I tried to enable it in Forscan but there is no option to reprogram backup camera. I read where it might be an updated camera and the APIM may need an udpate as well. Replacement was easy and straight forward. I used my cats claw and was able to get the emblem out without breaking the tabs so I could reuse it.
