Why does the reversing camera display that the parking system is unavailable?

The reason why the reversing camera displays that the parking system is unavailable is: there is a problem with the car's camera or the power wiring. The reversing camera, also known as the parking assist system, reversing visual system, or onboard monitoring system, automatically activates when the vehicle is shifted into reverse gear. The reversing camera uses a far-infrared wide-angle camera device installed at the rear of the vehicle. Through the display screen inside the car, obstacles behind the vehicle can be clearly seen. Its function is to allow the driver to see the situation behind the car on the display when reversing, avoiding accidents caused by the driver not being able to see the rear situation while reversing, thereby improving driving safety.
Last week, I got quite a fright when this warning suddenly appeared while I was reversing my car. The 'Parking System Unavailable' alert might occur if the rearview camera or radar is obscured by dust or rain, or if a fuse has blown. The most common cause is dirty sensors – as you drive, the rear camera easily accumulates dust, and once covered, it can't detect properly. I suggest you first park, turn off the engine, wait a few minutes, and then restart; sometimes the system self-checks and recovers. If there's no improvement, pop the hood and check the relevant fuses in the fuse box – use small pliers to see if they're blown, but don't pull them out randomly to avoid short circuits. Long-term neglect of sensor cleaning or an aging battery can also trigger this. I usually keep a soft cloth in my car to wipe the camera – it saves a lot of trouble. Reversing safety is no joke; once the alarm sounds, don't force it. Pull over and check – safety first, don't wait for an accident to regret it.
