                Troubleshooting table for instrument manual control panel faults

When a fault occurs, the instrument will prompt the user with code and graphics:

fault code (decimal)fault stateCheck the location
E02brakeCheck the brake lever for short circuit, no return or damage
E06battery undervoltagecharge the battery
E07Motor failureMotor Hall fault, check whether the Hall wire is short, and whether the plug is plugged in properly. If all is good replace the motor.
E08Handlebar failureCheck the line and plug of the handlebar, if all are good, replace the handlebar.
E09Controller failureThe controller is damaged Replace the controller.
E10Communication reception failureexamine 1. Is there any disconnection in the instrument line? 2. Whether the connection between the controller and the instrument plug is in good condition. 3. Unplug the booster sensor to see if it reports. If it does not report, the sensor is short-circuited and damaged, and the sensor needs to be replaced. 4. Unplug the switch to see if it is reported. If it is not reported, the handlebar is short-circuited and damaged, and the handlebar needs to be replaced. 5. Unplug the motor Hall wire and see if it reports. If it is not reported, the motor Hall is short-circuited and damaged, and the motor needs to be replaced. 6. None of the above can solve the problem, use the replacement method to troubleshoot the fault, and replace the controller or instrument to troubleshoot which problem is.
E16Electric lock short circuitCheck the electric lock all the way, such as headlights, speakers, USB or other external devices for short circuit. Check the short-circuit point of the external equipment, check if one is turned off and turn it on after 1 minute to see if E16 is still reported.  1. If it is not reported, it is caused by the short circuit of the device you unplugged. 2. If the report continues to check the next short-circuit point, shut down and wait for one minute to start up, and so on. (Note: To check one place, you must shut down and wait for a minute before turning it on again).
