Solution
• Check if there is a short circuit in the wiring or installation.
• Replace the controller.
Check if the resistance of the display PCB is too high.
Check the connection wires between the sub-controller and the
main controller.
1. Check if the circuit between the display PCB and the controller
assembly is normal. If so, turn off the scooter, replug the
assembly wires, and then reboot the scooter.
2. If the fault code still exits, replace the display PCB or controllers.
Check the circuit of the controller or motor phase wires.
• Check if the accelerator resets completely, works, or its circuit is
normal.
• Disconnect the accelerator wiring and reboot the scooter.
• Check if the brake levers reset completely or work normally or
the brake lines are normal.
• Disconnect the wiring of the electronic brakes and reboot the
scooter.
• If the code occurs when you turn on the scooter, check if the
wiring of the main-motor Hall sensor is normal.
• If the code occurs when you brake, replace the main-motor or
controller.
• Check if the wiring of the sub-motor Hall sensor is normal.
• Replace the sub-motor or controller.
• If the code occurs when you turn on the scooter, check if the
battery voltage is normal.
• If the code occurs during riding, replace the battery or controller.
• Reboot the scooter.
• If the code still occurs after you reboot the scooter, replace the
controller.
• Cool down the scooter.
• If the code still occurs after you cool down and reboot the
scooter, replace the controller.
Cool down and reboot the scooter.
