1, car system card, car system can't run. If it is not handled in time, the car will get stuck, resulting in the phenomenon that the reversing image will not be displayed.
2. Short circuit or poor contact. After disassembly, back up the camera, visually check whether the connector is loose, and use a multimeter to check whether the voltage signals of the host receiving line and the camera control line are normal. After inspection, it is determined that the line is faulty and needs 4s point maintenance.
3, reversing camera failure, solution, after checking that the line is normal, you need to check the reversing camera itself failure, the camera will be black or white when it fails, at this time, the central control can enter the reversing display interface, but there is no image output, you need to replace the new camera in this interface, and the failure can be lifted.
4. The reversing image module is faulty. Solution: After all the above faults are eliminated, it is necessary to check the faults of the reversing image module. The reversing image module is equivalent to a transfer station (some models are integrated in the main engine), and the normal failure probability is small, which can be eliminated. If the reversing image module fails, the car will be sent to 4s for repair.
