What Causes the Reverse Camera to Not Respond When Shifting to Reverse?
2 Answers
When the reverse camera does not respond after shifting to reverse, the possible causes include the following: 1. The display unit may be frozen or slow to respond, which can usually be resolved by restarting the navigation system or the vehicle. 2. If the screen is black or blue, it may indicate an issue with the AV wiring. 3. For aftermarket reverse cameras, which typically draw power from the reverse lights, check if the reverse lights are functioning. If they are not, inspect the fuse. If they are working, examine the reverse camera wiring for looseness or poor connections. 4. If the factory-installed reverse camera does not respond when shifting to reverse, it should be taken to a 4S shop for inspection. 5. If the reverse camera does not display after shifting to reverse while the central control screen works normally and the reverse radar functions properly, it may be due to poor contact between the reverse camera module and the video cable. 6. The issue could also stem from a poorly connected or damaged vehicle camera.
When I encounter a situation where the reversing camera suddenly stops responding, I usually start with the simplest checks, such as seeing if the rear camera is blocked by mud or dirt, and try cleaning it. If the problem persists, I then check if the fuse has blown. The location of the fuse box varies by model, typically under the driver's seat or in the engine compartment; find the fuse labeled for reversing or the camera and replace it. Another possibility is poor contact in the wiring, especially if the connectors near the rear trunk are loose or corroded. A faulty display screen can also be a cause, so check if the vehicle system settings are correct, such as the resolution or mode being misconfigured. If the control module is damaged, it's more troublesome and requires professional diagnostic tools. I recommend not ignoring this issue and addressing it promptly to avoid hitting objects while reversing, which could be dangerous. Regular car washing and maintenance can help reduce such problems.
