Why does the reversing camera show no signal?

Reversing camera showing no signal is usually caused by poor line contact. It is necessary to promptly check the wiring and the connection points of the vehicle installation to see if there is any loose connection. If there is, it will naturally cause the reversing camera to malfunction. In this case, simply reconnect the loose part properly. The reversing camera, also known as the parking assist system, reverse visual system, or onboard monitoring system, is referred to as Vehicle Backup Camera in English. This system is widely used in various large, medium, and small vehicles for reversing or driving safety assistance. The reversing camera system can still provide clear visibility at night through infrared technology, with professional vehicle-mounted probes featuring further improved anti-magnetic, anti-shock, waterproof, and dustproof performance.
I previously encountered a situation where the reversing camera suddenly lost signal in my car. The most common causes are a loose or broken camera connection cable. This could be due to aging wiring from prolonged use or water ingress during car washing leading to a short circuit. When checking, first see if the camera lens is dirty or obstructed, and try cleaning it. Then inspect the camera connector in the trunk to ensure it's securely plugged in. Fuses are also crucial—open the fuse box to check for any blown fuses, as excessive current can sometimes cause them to burn out. If the screen displays everything else normally except for the reversing signal, it might be a software issue with the head unit; try restarting the car. Safety-wise, losing the reversing camera affects parking, especially in tight spaces, so it's recommended to get it checked at a repair shop promptly if an issue arises—don't delay. Older cars are more prone to this problem, and regular maintenance of the wiring can help prevent it.
