Why does the car reversing camera sometimes lose signal?
2 Answers
The reasons why the car reversing camera sometimes loses signal are: 1. Poor line contact; 2. Aging of the video power cord; 3. The reversing camera has been used for too long, resulting in poor chip photosensitivity. The car reversing camera refers to the reversing rearview system, which allows the driver to monitor the video images of both sides outside the car and the rear of the car in real time, avoiding accidents and theft. The features of the car reversing camera include: 1. Wide voltage input of the system, which can connect 4 channels of camera signals for various vehicles; 2. With 4-screen split function, you can choose single screen or 4 screens; 3. 4 groups of forced start signals, in any state, automatically switch to the reversing screen when reversing, and restore the original state after reversing, realizing the automatic wake-up function of reversing.
My reversing camera has been acting up these past couple of days - sometimes the screen goes black, sometimes it works fine. It's so annoying that I've had to rely on mirrors to reverse blindly. Later, I asked an experienced mechanic to check it together. The most likely issue is a loose connection in the camera wiring. Those wires keep bending back and forth near the trunk lid, and constant vibration can cause poor contact. Another possibility is the camera lens getting dirty with mud splashes - you should clean the lens promptly after driving on dirt roads in rainy weather. It could also be a faulty reverse gear switch failing to trigger the signal when shifting. I've developed a habit of asking technicians to inspect the rearview wiring during every maintenance, especially in winter when thermal contraction affects connections. For a permanent fix, you'd need to disassemble and properly crimp the wire connectors. If you're not handy with tools, it's safer to visit a professional auto repair shop.
