Recently, my 2015 i3 back up camera has stopped working. At first, it displayed gray lines with an orange traffic cone. Then sometimes it would display a garbled image for just a moment and the screen would go black, but still contain the proximity sensor data on the screen. Now, it never displays an image at all. My thought is the camera failed, but I am taking some steps to attempt to troubleshoot the camera because not much info on the workings of the camera can be found online.
First, the hatch is shut properly.
Second, the camera is switched on in the options, but the icon is gray and is not selectable.
Third, the 12v battery is a year old Remy battery that was coded by me after . After removing the rear bumper and unplugging everything. I get exactly 12v at the camera plug. Using the legs of an old led, ground is the pin hole with the black wire and power is the green wire with blue stripe. 12v is kind of low even though it is a 12v battery, so I removed the battery and placed it on the charger, which read 60% charge. Will update as this progresses.
