Error Codes: Alpha | Alpha S (2021-2023)Updated a month ago
If your First Generation hub-motor Vvolt ebike displays any of the following codes on the Xplova EH-02 display, please consult the following chart. Should you not be able to resolve the issue on your own, please email us at [email protected] for guidance!
Here is a rundown of the most common error codes we've seen:
E001
The most common error code we've seen is E001 -- the HMI communication fault -- it looks like this on your display:
This is most often the result of a communication fault between the handlebar display and in-bike controller, although it can be the result of pinched wires, broken pins, or a faulty battery. Fear not -- we're here to help. Reach out to [email protected] and we'll work through solutions with you!
Here is the full list of error codes:
| Code | Code Explained | Description | Resolution |
|---|---|---|---|
| E001 | HMI Communication Error | Signal Interference caused by HMI receiving duplicate data packets from battery and controller | Contact Vvolt |
| E011 | Battery - Cell Over Voltage | Reboot battery | |
| E012 | Battery- Cell Under Voltage | Reboot battery | |
| E013 | Battery - System Under Voltage | Motor has detected too low voltage. Potentially occurs when battery is low and assist level is high and working hard. Ensure battery is charged then try steps to the right | 1. Check the battery voltage and fully charge the battery. 2. Check whether the wire between HMI and motor is damaged 4. Update motor firmware 5. Replace motor |
| E014 | Battery - Short Circuit | Contact Vvolt | |
| E015 | Battery - Over Discharging Current | Contact Vvolt | |
| E016 | Battery - Over Charging Current | Contact Vvolt | |
| E017 | Battery - Cell Over Temperature (charge) | Unplug battery and charger and move to a cooler area. Wait 30 min before attempting to charge again | |
| E018 | Battery - Cell Over Temperature (discharge) | Reboot the battery, wait 10 minutes before rebooting HMI | |
| E019 | Battery - FET Over Temperature (charge) | Unplug battery and charger and move to a cooler area. Wait 30 min before attempting to charge again | |
| E020 | Battery - FET Over Temperature (discharge) | Reboot the battery, wait 10 minutes before rebooting HMI | |
| E021 | Battery - Cell Under Temperature (charge) | Unplug battery and charger and move to a warmer area. Wait 30 min before attempting to charge again | |
| E022 | Battery - Cell Under Temperature (discharge) | Reboot the battery. | |
| E023 | Battery - Low Capacity | Charge the battery | |
| E024 | Battery - Fault | Contact Vvolt | |
| E025 | Battery - Cell NOT Balanced | Plug into charger | |
| E026 | Battery - Charge FET Damaged | Contact Vvolt | |
| E027 | Battery - Discharge FET damaged | Contact Vvolt | |
| E028 | Battery - Fuse Blown | Contact Vvolt | |
| E029 | Battery - Other | Contact Vvolt | |
| E049 | Control - Speed Sensor Abnormal | Internal speed sensor in hub motor is not working properly | Contact Vvolt for motor repair/replacement |
| E047 | Control - Voltage Abnormal | Contact Vvolt | |
| E040 | Control - Current Abnormal | Contact Vvolt | |
| E041 | Control - PAS/Throttle Abnormal | Contact Vvolt | |
| E042 | Control - Motor Phase Lose | Contact Vvolt | |
| E043 | Control - Motor Hall Sensor Abnormal | There is a faulty hall sensor in the motor or a damaged pin in the motor cable | Replace Motor |
| E044 | Control - Brake Abnormal | There is no brake switch in Vvolt motor systems | N/A |
| E045 | Control - Over Temperature | Turn off HMI, wait 10 minutes to reboot and lower PAS level | |
| E046 | Control - Motor Blocked Rotor | Contact Vvolt | |
| E048 | Control - Other | Contact Vvolt |
