There are many reasons why the reverse camera does not display when shifting to reverse gear, mainly including poor contact in the wiring and switch, malfunction of the reverse camera module, and a dead car battery. Below is a detailed explanation: Poor contact in the reverse camera wiring and switch: If the connection wire between the camera and the car display screen comes loose, or if the reverse camera switch is damaged, it will cause the reverse camera not to display. In this case, the wiring needs to be reconnected, and if necessary, a new switch can be replaced. Malfunction of the reverse camera module: There are many reasons for the reverse camera module to malfunction, including system disorder, garbled module, and formatting of the reverse camera. In this case, it is necessary to visit a repair shop and have a professional inspect it. Dead car battery: The display screen of the car reverse camera is powered by the car battery. When the car battery is dead, the reverse camera will not display. In this case, the car battery should be charged promptly.
Last time my car's reversing camera suddenly went black, so I took it to the repair shop and they identified three common issues: either the camera was covered in mud, the wiring connector was loose, or the fuse was blown. The mechanic said the rear camera is particularly delicate and even splashing water on rainy days could cause a short circuit. Another possibility is that the central control screen doesn't switch over when shifting into reverse, which might be due to a system glitch. The scariest scenario is poor contact in the reverse signal line near the transmission—my neighbor had this issue and spent 300 yuan replacing the wiring. It's recommended to clean the camera with a damp cotton swab and check if the wiring harness connectors under the trunk lid are loose.
