1. Check the display wires for breaks.
2. Check whether the connection between the controller and
the instrument plug is in good condition.
3. Unplug the PAS sensor to see if an error is reported. If no
error is reported, the sensor is short-circuited and damaged,
and the sensor needs to be replaced.
4. Unplug the switch to see if an error is reported. If no error
is reported, the handlebar is short-circuited and damaged,
and the handlebar needs to be replaced.
5. Unplug the motor hall wire to see if an error is reported. If
no error is reported, the motor Hall is short-circuited and
damaged, and the motor needs to be replaced.
6. If the above methods cannot solve the problem, use the
