Why Does the Reversing Camera Turn Gray?
2 Answers
Here is a detailed introduction to the meanings of different colored trajectory lines in the reversing camera: 1. Red trajectory: The red trajectory represents the warning line, indicating a distance of 30cm from the rear of the vehicle. When the vehicle approaches this line, the parking space is just right, and no further reversing is allowed to avoid accidents. 2. Yellow trajectory: The yellow trajectory represents the deceleration line, indicating a distance of 60cm from the rear of the vehicle. You can continue to reverse but should slow down, check the distance, and adjust to a suitable position. 3. Green trajectory: The green trajectory represents the normal safety line, indicating a larger distance between the obstacle and the rear of the vehicle, allowing you to reverse with confidence.
Having driven for decades, I've seen countless instances where the rearview camera suddenly goes gray. The most common cause is the lens being covered by dirt, like mud or snow, blocking the light transmission and resulting in a blurry screen. Simply wiping it gently with a clean cloth can immediately restore clarity. If it remains gray after cleaning, there might be a wiring issue—perhaps a loose connector or a signal cable chewed through by rodents. The connectors near the trunk are particularly prone to loosening; try opening the cover and reinserting them. Another possibility is the main system freezing—restarting the car engine might help. For safety, if the camera fails while reversing, stop immediately and avoid relying solely on intuition. Regularly checking and cleaning the camera can prevent many headaches.
