Why doesn't the display automatically switch when reverse gear is engaged?

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.

My car had the same issue before, where the reverse camera image wouldn't display. It turned out the camera wiring harness connector was loosened by vibration, and simply pressing it firmly back into place solved the problem. If the wiring harness is fine, common causes include: worn or faulty reverse gear switch failing to trigger display switching; software conflicts after vehicle system updates (resetting onboard settings might help); blown fuses from repeated vibrations (try replacing them); or incorrect display mode settings (switched to manual instead of automatic in the menu). When troubleshooting, don't rush to disassemble—first check other functions like Bluetooth calls to rule out main circuit faults. If unresolved, seek professional repair. Regular wiring maintenance helps prevent such issues.

When the reverse gear is engaged but the display does not respond, it may be due to a failed reverse sensor not sending position signals, or aging wiring harnesses connected to the display module causing an open circuit. System settings, such as the default switch to reverse mode being disabled, can also cause this issue. A blown fuse is one of the common reasons—check if the reverse circuit fuse has melted. Internal firmware bugs, such as incompatibility with software updates, can also occur occasionally. In such cases, first use a vehicle diagnostic tool to scan for error codes and locate the problem. If necessary, updating the software or resetting the settings may restore functionality. However, avoid random disassembly or modifications to prevent further damage.
