What Causes the Reversing Camera Screen to Go Black?
2 Answers
The reasons for the reversing camera screen going black are: 1. Aging of the video power cable: Try replacing it with a new one. If the black screen issue is resolved, it indicates a problem with the video power cable. 2. Wiring issues: This is the most common cause of failure. Since the wiring harness for the reversing camera runs from the dashboard to the trunk, the lengthy route increases the likelihood of poor contact at some point in the harness or connectors, requiring thorough inspection. 3. Prolonged use of the reversing camera leading to poor chip photosensitivity, resulting in a black screen.
Last time I encountered a black screen on the reversing camera, I first climbed to the rear of the car and touched the camera—sure enough, it was covered in mud. A dirty camera is the most common cause, especially after driving on dirt roads in the rain. Then, I checked the wiring harness connector on the trunk lid, as repeatedly opening and closing the trunk can easily cause wire breakage. Don’t forget the fuse either—the 10-amp fuse for the reversing camera is labeled in the fuse box on the left side of the dashboard; if it’s blown, it needs replacement. A frozen head unit can also cause a black screen—just turn off the engine for ten minutes and restart it. You can usually fix it yourself by wiping the lens with a wet wipe and reconnecting the connectors. If that doesn’t work, then take it to the shop to check for wiring issues.
