What is the reason for the reverse camera displaying no video signal?

The reason for the reverse camera displaying no video signal is that the vehicle's reverse gear synchronizer is damaged. The reverse camera is damaged, or there is looseness or damage between the camera and the connecting cable. There is a short circuit or looseness in the wiring between the reverse camera and the vehicle's central control unit. Reverse Camera System: The reverse camera system used in motor vehicles is very convenient. It effectively observes the rear situation by feeding the camera's view back to the central control screen in video form, allowing the driver to clearly see from inside the vehicle and avoid collisions while reversing. Reverse Radar System: When the vehicle approaches an obstacle, the radar will emit a sound and display the distance.
Last week, I also encountered the issue of 'no video signal' while reversing my car. At first, I thought the system was malfunctioning, but after a quick inspection, I found that the camera lens was covered in mud. After cleaning it with a damp cloth, the display returned to normal. Another common issue is loose wiring connections, especially near the trunk or chassis wiring interfaces, which can become loose due to prolonged vibration. Try gently pushing the connectors to secure them. If the problem persists, check if the reverse camera fuse in the fuse box has blown and replace it with a new one at the corresponding position. Short circuits in the wiring are also common in humid weather, so avoid using high-pressure water jets to clean the camera area during rainy days. Regular maintenance can help reduce such issues. If you can't resolve it yourself, visit a professional repair shop promptly for diagnosis to avoid compromising driving safety.
When the reversing camera loses signal, my first concern is safety. Common causes include camera malfunction or power disconnection, such as aging or damaged wiring, or being crushed by heavy objects. First, check the connection cables near the trunk or center console to ensure they are intact. Don't overlook a blown fuse—locate and test the relevant fuse in the fuse box, replacing it if necessary. If the screen suddenly goes blank while reversing, don't force it. Instead, pull over and rely on manual observation with the rearview mirror to avoid collision risks. Preventive maintenance is crucial—take time each week to clean the camera lens and inspect the wiring harness, extending the device's lifespan while ensuring driving safety.
