Why doesn't the display automatically switch when reverse gear is engaged?
2 Answers
The reasons why the display does not automatically switch when reverse gear is engaged are: 1. The reverse radar camera is malfunctioning; 2. The power supply for the reverse radar image is loose or damaged. Solutions for the issue of the display not automatically switching when reverse gear is engaged: 1. Reset and reinstall according to the manual; 2. Check if the reverse radar camera is functioning properly, and replace it if damaged; 3. Inspect whether the power supply for the reverse radar image is loose; 4. Open the rear light and rewire the connections. When the car is put into reverse gear, the far-infrared wide-angle camera device located at the rear of the car is automatically activated, displaying the rear view clearly on the reverse LCD screen. The reverse camera monitoring system is more intuitive and reliable than the all-around reverse radar.
I've encountered a similar issue where the screen doesn't automatically switch to the reverse camera when shifting into reverse gear, which is quite annoying. Possible causes include a faulty or poorly connected reverse gear sensor that fails to send the correct signal to the display module, or loose wiring or a short circuit causing unstable current. Sometimes it's a vehicle settings problem, such as the reverse display function being manually turned off—just reset it in the display menu to restore it. Another possibility is a blown fuse affecting the system's power supply. I recommend troubleshooting step by step: First, try manually activating the reverse camera to see if it displays. If it does, the issue likely lies with the sensor. Next, check the fuse box and replace any blown fuses. If that doesn't work, take it to a professional shop and have a technician use a diagnostic tool to read the fault codes and check if the module has failed. Don't ignore such minor issues, as they can affect safe driving.
