What's the matter when there is no response from the reverse camera screen when shifting into reverse gear?

When there is no response from the reverse camera screen after shifting into reverse gear, first check if the reverse lights are on. If they are not on, inspect the reverse light fuse, switch, and wiring. If the lights are on, check the head unit and its wiring. The reverse camera, also known as a parking assist system, reverse visual system, or vehicle monitoring system, is widely used in various large, medium, and small vehicles for reversing or driving safety assistance. Here are some driving precautions: 1. Check the rearview mirror: Always use turn signals and slow down when turning or changing lanes; always check the rearview mirror before turning. Left turns mainly require checking the left rearview mirror, right turns mainly require checking the right rearview mirror, and both left and right turns require checking the interior rearview mirror. 2. Don’t stare at the front of the car: When driving on a clear road, look straight ahead about 100 meters, not at the immediate front of the car. 3. Press the clutch: Generally, when decelerating above 40 km/h, there’s no need to press the clutch first; press the clutch when the speed drops to about 20 km/h. 4. Steering: Turn the steering wheel slowly at high speeds and quickly at low speeds.

I've encountered similar issues while driving, like no response from the screen when shifting to reverse gear. There are usually several common causes that can be frustrating. The camera might be dirty or obstructed—try cleaning it, as sometimes mud or snow covering it can block the view. Additionally, a loose connection cable for the display can cause this; check the rear camera plug in the trunk to ensure it's securely fastened and not loose. System settings could also be the problem, such as a software glitch or unsaved parameters after a reset—try restarting the car's infotainment system to see if the image returns. If none of these work, a blown fuse in the circuit might be the culprit; locate and inspect the relevant fuse in the vehicle's fuse box and replace it if necessary. A malfunctioning reverse camera affects safety, especially during nighttime parking, so it's advisable to visit a professional auto repair shop for a thorough inspection as soon as possible to avoid inconvenience. Regular maintenance should include periodic cleaning of the camera and checking the wiring.

As a car enthusiast, I believe the malfunction of a reversing camera is mostly caused by hardware or wiring issues. Damage to the camera itself, aging internal components, or corrosion from moisture can all cause the image to disappear. If the display screen is unresponsive, it might be due to loose wiring, and you should check for poor connections from the rear of the car to the central console. Blown relays or fuses are also factors, as high current surges can burn out these components. When the vehicle's power supply system is unstable, such as abnormal alternator output, it can also interrupt the camera feed. You can use a multimeter to test the voltage or try gently tapping the camera area to rule out simple faults. A friend of mine fixed his car this way, and delaying repairs might affect other functions.

Having driven for decades, I'm quite familiar with reversing camera issues. Usually when there's no response after shifting to reverse gear, it's most likely a poor connection - check for loose or corroded interfaces at the camera and rear bumper area. Blown fuses are also common; locate the labeled fuse in the dashboard fuse box and replace it. If the screen is unresponsive, try restarting the vehicle as the system occasionally freezes. Addressing these early prevents bigger troubles, otherwise parking becomes unsafe.
