What are the reasons for the malfunction of the Hyundai Elantra reversing camera?

The reasons for the malfunction of the Hyundai Elantra reversing camera include circuit failure; camera failure; voltage failure, etc. Circuit failure: Most cases where the reversing camera does not work are due to faults in the camera or video circuit. If the screen switches to a blue screen when shifting into reverse, it indicates that the central control screen is functioning normally and the reverse activation signal is also normal, but the video signal is simply not being transmitted to the screen. Camera failure: If there is no video signal input to the display, it could be an issue with the signal input or the camera. Check if the camera connection is loose. If there is no looseness, then check if the camera is functioning properly. Voltage interruption: The first step is to check if the camera's power supply is normal. You can test the voltage at the camera. If the voltage is abnormal, then check the continuity of the video circuit.
My family also drives a Hyundai Elantra, and we've encountered issues with the reverse camera not working. The most common reason is dirt on the camera lens, especially during rainy or dusty conditions when grime blocks the lens view—sometimes a simple cleaning can restore functionality. Another possible cause is a loose or corroded power cable. The reverse camera is powered by a fuse, and if it blows, the system won't respond. It's best to check the fuse box, locate the corresponding fuse, and replace it if necessary. Additionally, the rear camera is prone to impact damage, and the connector may come loose or get corroded by water, leading to poor contact. I once fixed it by tightening the wiring myself. If the issue lies with internal module failure, such as a damaged control circuit board, it's best to visit a professional repair shop for replacement. Regular maintenance, such as cleaning the lens and ensuring secure connections, can help prevent unexpected inconveniences.
I'm a car enthusiast and often fix such issues myself. When the reversing camera doesn't work, I usually start by checking the camera. Scratches on the lens or water ingress can cause the image to disappear, so try wiping it or using a defogging cleaner. Next, inspect the wiring connections—blown fuses are the most common issue, especially during current overloads. Replacing a fuse is cheap and effective. Use a multimeter to check voltage and confirm if the circuit is functioning properly. Don't overlook software issues either, such as accidentally disabling the camera function in system settings—re-enabling it or updating the firmware might restore functionality. The reversing module for the Verna is located in the trunk area, which is prone to moisture-induced short circuits, so timely dehumidification is crucial. In short, methodically checking from simple to complex steps can often lead to a DIY fix—safe and cost-effective.
It's really frustrating that the reversing camera stopped working just a few months after buying the new car. The most common issue could be damage to the camera lens, such as cracks or dirt blocking the signal, preventing it from displaying. It might also be a power supply problem, like a blown fuse, aging wires, poor contact, or disconnection. In cold weather, wires contract more easily, causing issues—try resecuring the plug. Occasionally, the system might freeze; restarting the vehicle could resolve the fault. If it doesn't improve, take it to the 4S shop to check the module and ensure a quick fix for worry-free driving.
