What to Do When the Reverse Camera Shows No Signal?
2 Answers
Reverse camera showing no signal is usually due to poor line connection. It is necessary to promptly check the wiring and the connection points of the entire vehicle installation to see if there is any loose connection. Here is some relevant information about the reverse camera display: Camera Installation Position: The camera is located above the rear license plate. The camera's shooting range is very limited and cannot capture objects near the corners or under the bumper. The displayed image may vary depending on the vehicle's direction or road conditions, and the distance shown on the screen may differ from the actual distance. Reverse Guide Lines: The reverse distance auxiliary lines are divided into three parts: red, yellow, and green. They respectively indicate the distance range of obstacles from the bumper, as follows: Red: 20 cm ~ 50 cm; Yellow: 50 cm ~ 150 cm; Green: 150 cm ~ 300 cm.
A few days ago, I encountered the same issue with my car—the screen displayed 'No Signal' when shifting into reverse, which made me so nervous that I immediately pulled over. First, I checked the rearview camera and found it covered in mud and grime. After gently wiping it clean with a wet wipe and testing again, the display returned to normal. If you face a similar problem, don’t rush to the repair shop—try these DIY steps first: The camera is usually located near the license plate or on the rear bumper and can easily get blocked by dirt. Cleaning it often works wonders. If dust isn’t the issue, it might be a loose wiring connector. Open the trunk, locate the camera’s wiring plug, and reconnect it securely. Alternatively, a blown fuse could be the culprit. Check your vehicle manual for the reverse camera fuse location (often in the small box near the driver’s seat), then replace it with a new one. I’ve fixed this myself at home several times, saving both hassle and time. Restarting the car can also help—turn off the engine, lock the car, wait five minutes, and then start it again and shift into reverse; the system might reset. If none of these steps work, it could be a hardware failure, and professional inspection is needed. Remember, if the reverse camera fails, double-check your mirrors or ask someone to guide you—safety always comes first.
