Why does the reversing camera work intermittently?
2 Answers
The reason why the reversing camera works intermittently is: Poor contact caused by a loose connection at the wiring junction between the reversing radar line and the vehicle's installation. The solutions for no signal from the car reversing camera are: 1. Restart the vehicle and turn off the music player; 2. Secure the data cable of the reversing camera; 3. Replace the reversing camera. The function of the car reversing camera is to allow the driver to see the situation behind the vehicle on the display when reversing, ensuring reversing safety. The reversing camera consists of a wide-angle camera, a control unit for signal transmission, an MMI display, an information display control unit, a TV tuner, and a CAN data harmonization bus.
I've encountered the reversing camera working intermittently several times, usually due to unstable wiring connections. Think about it - the camera is at the rear of the vehicle, and the wiring runs all the way to the center console. After prolonged bumps, the connectors may become loose or oxidized, causing intermittent signal loss. Additionally, during humid weather, moisture seeping into the joints can cause more frequent short circuits - I once checked and found the image was too blurry to see on rainy days. There are also power supply issues; if the car battery or alternator voltage is unstable, insufficient power to the camera can affect image display. If the screen shows garbled code or goes black, it might be a system software bug or aging display malfunction. I recommend regularly wiping the camera lens clean after parking to avoid dirt obstruction. If abnormalities are found, immediately use a multimeter to test circuit resistance and check if it's within normal range. Ignoring this could compromise safety, as reversing without a camera makes it easy to hit obstacles. It's better to schedule regular shop inspections to ensure safety. Remember to check wiring conditions during every maintenance to prevent small issues from becoming major problems.
