What causes the black screen issue in Teana's reversing camera?

[VeraAnn]

If the reversing camera of the Teana displays a black screen, it is most likely due to poor line contact. It is necessary to promptly inspect the wiring and the connection points installed in the entire vehicle to check for any loose connections. Relevant details are as follows: 1. Principle of the reversing camera system: It is a rearview technology based on visual measurement, which relies on the camera at the rear of the car to display the road conditions behind the vehicle on the central display screen. The driver can move the square representing the car body freely on the screen via the touch screen. If the position is appropriate, the square will change from red to green. At this point, simply engage the reverse gear and control the vehicle speed to complete automatic reversing. 2. Situations where the reversing camera system is limited: (1) The camera is covered by ice, snow, or mud. (2) The ambient light is dark. (3) Under extreme conditions, such as sun glare or headlights from the car behind shining directly. (4) The rear of the car is deformed or damaged. (5) Extremely high or low temperatures and significant temperature changes.
