Himiway eBike Error Code Finder: Diagnose Common Error Codes

Code 24

Motor Hall Sensor / Controller Abnormality

⚠ Cause: Motor Hall anomaly (70% probability) or controller fault (30% probability). Check for damaged wire jacketing with visible copper wire.

🔍 Check Method: Check the connecting cable between the controller and the motor for any physical damage or exposed copper wire.

💡 Solution: If wire casing is damaged, replace the part with the damaged short cable first (e.g., if damaged on controller side, replace controller). If no casing damage, cross-test with another bike/motor if possible. If cross-testing is not possible, replace the motor to resolve.

Code 30
