Xiaomi M365 is one of the most popular scooters in Lithuania, so its diagnostics are well known. This guide summarizes common symptoms, error codes, and the checks that help identify the issue faster.
If the scooter won’t turn on, shows errors, loses power, or brakes poorly, start with basic checks. For electronics and battery issues, we recommend a service visit to avoid further damage.
Common symptoms
- Scooter won’t power on or shuts off while riding.
- Charging does not start or the charger LED blinks.
- Motor stutters or power drops under load.
- Error codes appear on the display or in the app.
- Weak or uneven braking, squeaking noises.
- Loose folding mechanism or handlebar play.
Error codes and meanings
| Code | Likely meaning | What to check |
|---|---|---|
| 10 | Communication issue between controller and display. | Inspect connectors, wiring, and oxidation. |
| 11 | Motor Hall sensor or phase issue. | Check motor cable and connector integrity. |
| 14 | Throttle sensor error. | Check throttle cable and for sticky movement. |
| 15 | Brake sensor error. | Inspect brake lever, cable, and sensor alignment. |
| 18 | Battery/BMS communication error. | Check battery connector, BMS wiring, oxidation. |
| 21 | Protection triggered (overload/temperature). | Let it cool down and reduce load; monitor if it repeats. |
Home diagnostics
Before visiting a service center, do a few safe checks. They help determine if the issue is mechanical, electronic, or battery-related.
Quick checks
- Charge the battery to 100% and observe if charging is stable.
- Check tire pressure and visible mechanical looseness.
- Inspect connectors near controller and battery for oxidation.
- Listen for unusual motor noises or grinding.
When to stop
If you smell burning, see smoke, notice battery deformation, or moisture inside electronics, stop immediately and contact a service center.
Preventive care
- Check tire pressure and tread regularly.
- Avoid deep puddles — moisture quickly damages electronics.
- Reduce long uphill loads if you feel overheating.
- Store the battery at 30–80% if not used for a while.
Why service repair helps
- Proper testing equipment and quality replacement parts.
- Safe battery and BMS handling.
- Clear explanation of the fault and final price.
- Warranty on completed work.
Quick summary
- Codes 10/14/15 often point to sensors.
- Charging issues are frequently caused by oxidation.
- Stop immediately if you smell burning.
