Why is there no signal in the car's reversing camera?
2 Answers
The reasons for no signal in the car's reversing camera are: 1. Poor line contact; 2. Damaged camera; 3. Faulty gear position sensor. The method to activate the car's reversing camera is: engage the reverse gear, and the reversing camera will automatically turn on. The car's reversing camera system uses a far-infrared wide-angle camera device installed at the rear of the vehicle, allowing clear visibility of obstacles behind the car through the display screen inside the vehicle. The function of the car's reversing camera is: to enable the driver to see the situation behind the car on the display when reversing, avoiding accidents caused by the driver not seeing the rear situation during reversing, thereby improving driving safety.
I encountered the same issue last time when reversing—the screen suddenly went black with no image. Later, I found out that the camera cable in the trunk had come loose, possibly due to frequent opening and closing of the trunk shaking the connection. You should first check the camera's wiring, especially around the bends of the trunk lid where it's prone to pulling. Then, see if the rear bumper camera is blocked by mud or dirt. If everything seems fine, you might need to check for any short circuits or breaks in the wiring, particularly along the undercarriage. If all else fails, consider whether the head unit or the camera itself is faulty. I recommend trying to troubleshoot it yourself first before heading to a professional repair shop, as it could easily cost several hundred bucks.
