Kepler 52V - 2026: Error CodesUpdated 15 days ago
If your display shows an error code, the system has detected a specific electrical or hardware issue. Use the reference table below to identify the code and perform the recommended troubleshooting action.
Common Error Codes & Solutions
| Code | Description | Recommended Action |
|---|---|---|
| Error 04 | Throttle engaged at start-up | Release the throttle completely, turn the bike off, and power it back on. Ensure nothing is pressing or snagging the throttle lever during boot-up. |
| Error 05 | Throttle malfunction | Check the throttle wiring harness for tight connections or damaged pins. Contact support if the error persists. |
| Error 08 | Motor Hall signal failure | Inspect the main motor cable barrel connector located near the rear chainstay. Ensure the arrows align and the connection is fully seated without bent pins. |
| Error 10 | Motor overheating | Power off the system and stop riding immediately to allow the motor internal temperature to cool back down below its protective safety threshold. |
| Error 25 | Sensor signal error | Torque or cadence sensor signal issue. Inspect sensor wiring harnesses near the bottom bracket for loose connectors or wire damage. |
| Error 30 | Communication lost | The display unit is not receiving data from the main controller. Inspect all main wiring harness quick-disconnect connections between the display, harness, and controller. |
PRO TIP: When checking any cable connector or quick-disconnect plug, always power off the bike system and remove the battery packs first to prevent short circuits.
