The rearview camera is not displaying, what could be the issue?

The reversing camera may be damaged or obstructed, the display screen for the reversing camera may be damaged, there could be poor electrical contact in the wiring, or the battery may be depleted, causing the reversing camera to lose power. Below are detailed explanations of the relevant information: Camera damage: If the camera is damaged or obstructed, it cannot upload images to the computer, so nothing is displayed. Display screen damage: If the display screen is damaged, it will either remain black and fail to start or show distorted images, which usually indicates a malfunction. Poor wiring contact: Frequently driving on rough roads can cause the internal wiring of the vehicle to become loose or detached due to the bumpy conditions. When there is poor contact in the wiring, the images captured by the camera cannot be transmitted to the main unit, resulting in no display for the reversing camera.

I've encountered this issue too. Last month, the screen suddenly went black while reversing. Don't rush to repair it just yet; try these three things first: The most common cause is the lens being covered in mud or water—just wipe it clean with a damp cloth. Another frequent issue is a loose wiring harness connector inside the trunk; simply press the plug a couple of times. Then, restart the car's infotainment system by holding the power button for 10 seconds. If it still doesn’t work, there’s an 80% chance the camera itself is faulty, especially after washing the car in winter, which can easily cause a short circuit. Remember not to remove the trim panels yourself—just go to a modification shop and spend around 300 yuan to replace it with an aftermarket camera, which offers the same clarity at half the price. Also, check the reverse light fuse, as a blown fuse can affect the camera's power supply too.

From a veteran driver's perspective: the causes of rear camera failure are quite concentrated, mainly falling into three areas - wiring, lens, and head unit. Lift the trunk lining and focus on checking for oxidized wire connectors - just sand the contact points. Unstable power supply to the camera can also cause black screens; borrow a multimeter to check if the vehicle voltage drops below 12V. Pay special attention if you've modified the head unit - many off-brand units can't properly support OEM cameras. Like my decade-old car, the screen gets distorted when the lens fogs up in rain - simply blow-dry the lens gaps to fix it. After repairing the reversing camera, remember to clean the license plate light cover - these two are often serviced together.

Girl, I just dealt with this issue last week. The screen suddenly turned snowy while reversing, and restarting didn't help. The mechanic said the wiring near the license plate light was chewed through by rats, and it cost 120 yuan to rewire it. He also taught me a trick: if the edges of the camera feel warm when starting up, it's working normally; if they're cold, check the power supply. Now I regularly wrap the trunk wiring harness with tape and put a few mothballs to keep rats away. Remember, if the reversing camera fails, don't panic—you can still park just fine using the rearview mirror and radar.
