Why is there no signal in the car's reversing camera?

No signal in the reversing camera may be due to the following situations: 1. The data cable connected to the reversing camera is loose or has poor contact. 2. The reversing camera is damaged. 3. A fault in the gear position sensor. Below is some introduction to the reversing camera: The reversing camera, also known as the parking assist system, or reversing visual system, or on-board monitoring system, etc. This system provides a more intuitive and clear view of the situation behind the car when reversing, making it one of the most practical configurations for reversing safety. When the reverse gear is engaged, the system automatically activates the high-definition reversing camera located at the rear of the car, displaying a clear image of the rear situation on the reversing LCD screen, allowing you to accurately grasp the road conditions behind.
I've driven several cars and encountered the issue of no signal from the reversing camera a few times. There could be quite a few reasons for this. The most common is a dirty camera or one covered in mud—try cleaning the lens with a damp cloth. Another possibility is a loose wiring connection; the wires near the trunk opening area are prone to shaking loose, so check if the plug is securely connected. Sometimes, the screen input source is set incorrectly, such as being in navigation mode, so you'll need to switch it back to reverse mode. It's also possible that a fuse has blown; try replacing it with a new one from the fuse box to see if that helps. I always check these things when doing DIY repairs, but if the problem persists, it's safer to take it to a professional auto repair shop. After all, a malfunctioning reversing camera increases the risk of scratches, especially when parking at night with poor visibility—safety first.
As a seasoned driver with over a decade of experience, when the reversing camera loses signal, I start troubleshooting from the basics. First, check if the camera lens is obstructed and gently clean any dirt on the surface with a soft cloth. Next, inspect the wiring connection points in the trunk area - if plugs are loose, resecure them properly. A blown fuse is another common culprit; locate the fuse position using the vehicle manual and try replacing it. Additionally, display unit malfunctions can also cause signal loss, so verify the system settings are correct. All these steps are simple and quick to perform, taking just minutes. If the issue persists after checking, don't delay - contact a repair shop immediately where professionals can accurately diagnose the problem using testing equipment to prevent potential driving safety hazards. During routine maintenance, I also recommend periodically inspecting these components to avoid sudden failures.
