When there is a fault in the Youin scooter, you will start to hear beeps, of varying duration, both long and short. They have a meaning. The long beeps refer to the tens of the code, and the short beeps to the units of the code. It is like a machine-human translation morse code. Depending on the problem you have, the solution will be more or less expensive.
When an electronic device beeps, or emits lights, there is likely to be an internal problem in one of its components, and in this case, as an electric scooter has a lot of electronic components, the same thing happens. The failures of the scooter may be because, for example, we have not used a compatible charger for the scooter, or because we have wet it too much. Remember that the scooter can be carried without problem in a light rain, but if we put it in deep puddles perhaps some internal components will be affected.
Error code table of Youin SC3000&SC4000(Yougo L & XL Previous version) scooter
| Code | Meaning | Inspection method |
| E1 | Communication failure | Check if the plug-in terminals of the main line are in good contact. |
| E2 | Fault in HALL | Check for loose motor Hall line connector terminals; 2. Replace motor 3. Replace motor HALL |
| E3 | Temperature protection | When driving for a long time, E3 will be displayed, just turn it off and wait for a moment, then it will be OK. |
| E4 | Controller failure | Change controller |
| E5 | Low voltage | Charge the battery. |
| E6 | Stopped force | When the wheel is locked and still accelerating hard, then it will display E6. Check the motor cable if all wires are OK or if any wires are shorted after stall force. |
| E7 | Throttle failure | 1. Check that the “white 3-pin cable” with the throttle connection is OK or loose; 2. If OK, replace the throttle. |
| E8 | Overvoltage protection | If the controller is under over current protection, the temperature is too high, then the motor is short circuit, it will show E8, then restart the device to check, if still have E8, then check the motor if the motor is OK, if the motor still works can rotate, then wait a few minutes when the temperature is low it will be OK, if the motor is blocked, replace the motor, maybe need to replace the motor + controller together. |
