GT2 Display Error Code Definitions

Error Code Definition
03 Motor Failed to Start Properly: Check the 3-phase motor cable and Hall sensor connector for poor contact. Also inspect for excessive load or wheel jam (e.g., during climbing). If the issue persists after reconnecting cables, the controller or motor may be damaged.
04 Low Battery Voltage Protection: Battery is under-voltage and enters protection mode. Charge the battery.
