What to Do When the Display Screen Remains On After Turning Off the Key for an Electric Vehicle?

After turning off the engine, if the display screen remains on, use a car diagnostic tool to enter the system and read the data stream. It is likely due to an issue with the display screen's power supply module, which requires timely inspection and repair. First, locate and open the fuse box near the battery. Then, find the relay for the power distribution module on the back, identifying the corresponding relay based on its position. At this point, you can try replacing it with a new relay. If the problem is resolved, it indicates a relay malfunction.
I ran into this issue just the other day. After turning off the key on my little electric scooter, the dashboard lights were still on, which was quite annoying. I figured it might be that the system didn't fully power down—sometimes vehicles have a delayed screen-off feature to display certain information, and it would turn off after a while. If the lights are still on after a few minutes, then you should pay attention; it could be an issue with the key switch or a loose power supply line, like a blown fuse or a stuck relay. I tried fixing it myself—first, I checked if the key was fully removed and then reinserted it to see if that worked. If not, I popped the hood to inspect the fuse box; replacing a small fuse might do the trick. In the end, if nothing worked, I just called the repair shop directly—no point in pushing through and risking a dead battery that could leave the car unable to start.
