What are the reasons for no signal in the reversing camera?
2 Answers
The reasons for no signal in the reversing camera are: 1. When the car is just started, it may interfere with the operation of the reversing camera. You can try restarting the car or turning off the radio or music player; 2. The probe of the reversing camera is damaged or the chip's photosensitive signal is blocked due to prolonged use, requiring inspection and repair at a 4S shop; 3. Poor line contact. It is necessary to promptly check the wiring connections with the vehicle's installation to see if there is any loose connection. The reversing camera function uses a rear-mounted camera to capture real-time images of the area behind the vehicle, which are then displayed on the central control screen. When parking, the driver can intuitively observe the actual situation behind the vehicle based on the screen display, greatly enhancing parking safety.
I've been in the auto repair business for over a decade and have seen many cases of no signal in rearview cameras. Common causes include damage to the camera itself, such as water ingress or physical impact. Wiring issues are also frequent, like aging, loose connections, poor contact, or short circuits in the rear camera harness. Another common issue is blown fuses; if the circuit is interrupted, naturally there will be no signal. Additionally, problems with the head unit system, such as software glitches or incorrect settings, can interfere with image transmission. I once worked on a car where the trunk seal had aged and leaked, allowing moisture to corrode the wiring connectors. I recommend car owners start by checking the fuse, located in the toolbox on the driver's side—try replacing it with a new one. If that doesn’t work, inspect the wiring near the camera for secure connections. Don’t overlook safety; driving without a rearview image increases the risk of accidents, so it’s best to get it fixed at a repair shop as soon as possible.
