Segway Max Error Codes

 

In this article we will discuss the known list of error codes for the Segway Ninebot Max Scooters and what to do as an attempt to fix them.

For each error code we will list:

 

 

Error Code 10

Communication abnormality between the display and the main control board.

When error 10 is shown if the LCD can not communicate with the controller. First try resetting the scooter. If that does not work, try unplugging the dashboard and then plugging it back in. This may cause it to begin working again but it may resume flashing 10 one it is powered on. If that doesn't work flashing or updating the firmware should be attempted. If the issue still persists, replace the LCD or controller, in that order.

 

 

Error Code 11

Motor A-phase current sampling abnormality.

When error 11 is shown if the motor is not reading properly. First check the phase line of the motor for any fraying, clips, kinks, or cuts. If there is no issue with the phase line then replace the controller and if the issue persists, replace the motor.

 

Error Code 12

Motor B-phase current sampling abnormality.

When error 12 is shown if the motor is not reading properly. First check the phase line of the motor for any fraying, clips, kinks, or cuts. If there is no issue with the phase line then replace the controller and if the issue persists, replace the motor.

 

 

Error Code 13

Motor C-phase current sampling abnormality.

When error 13 is shown if the motor is not reading properly. First check the phase line of the motor for any fraying, clips, kinks, or cuts. If there is no issue with the phase line then replace the controller and if the issue persists, replace the motor.

 

Error Code 14

Throttle Hall sensor abnormality.

When error 14 is probably the most common error code. We have a whole article dedicated to this error code here.

 

 

Error Code 15

Left Brake Hall sensor abnormality.

When error 15 is shown when the brake hall sensor on the left side is not reading properly. You can usually replicate the issue by holding down the brake handle while the scooter is booting up. This error can also be caused by the magnets coming dislodged from inside the brake. There are many steps to try fixing this issue. Please see the image below.

 

Error Code 16

Brake Hall sensor abnormality on the right side.

When error 16 is shown when the brake hall sensor on the right brake handle is not reading properly. You can usually replicate the issue by holding down the brake handle while the scooter is booting up. This error can also be caused by the magnets coming dislodged from inside the brake. There are many steps to try fixing this issue. Please see the image below.

 

Error Code 18

Motor Hall sensor abnormality.

When error 18 is shown when the scooter detects an abnormal reading from the hall sensors in the motor. This can be due to an unplugged cable, or a blown sensor/resistor. Check the 5-pin hall connector of the motor and visually inspect that it is still connected and is not damaged in anyway. Any fraying, clips, kinks, or cuts means it will need to be replaced. If everything is normal replace the controller and motor in that order.

 

 

Error Code 19

Abnormal battery voltage detected.

Error 19 is shown when the battery is under the correct voltage reading. When this happens the battery usually needs to be charged. The battery LED should do one of 3 things, turn solid red, flash between red and green, or turn solid green. If the LED is solid red, let the battery charge. If the LED flashes between red and green, Let it charge for about an hour and it should start to charge normally. If the LED stays green then replace the battery. If this does not work follow the outline below. Reset the scooter and if that does not work, replace the controller first and testing the scooter, followed by the battery.

 

 

Error Code 21

BMS communication error. 

Error 21 is shown when the controller can not receive data from the BMS/Battery. Start by checking the battery communication connection. This is a 4-pin data wire that may need be plugged back in. It should click into place. Plug the scooter in for a few hours to see if the battery charges properly. Otherwise test the scooter with a working controller followed by a working battery.  

 

Error Code 22

Wrong BMS password.

Error 22 is shown when a rental vehicles is not properly STLinked or has the wrong firmware version uploaded. A temporary fix would be to hold the throttle and brake briefly at startup to ignore this error. For a more permeant solution refresh the serial number is the Segway portal. If the scooter still does not work replace the controller followed by the battery.

 

Error Code 23

BMS default serial number.

Error 23 is shown when the battery's serial number has the default number. This is similar to error 35. The serial number can not be 3GA0016A1A0001. Fix this my changing the BMS serial number using the ninebot launcher app. Otherwise replace the battery followed by the controller.

 

Error Code 24

System voltage detection abnormality. 

Error 24 is shown when the controller detects an abnormal battery voltage. This is most commonly happens when someone upgrades the battery. In some cases the battery may have become overcharged. If the battery upgrade caused the issue, upgrade the firmware on the controller to match the current battery setup. If the error happened without any pervious catalyst, the battery needs to be run down,  recharged, or replaced. To tun the battery down leave the scooter on for a while and  turn the headlight on to help run down the battery. If the voltage runs down and the error goes away, keep using the scooter until it is near 25% and then charge it fully again. If this or charging the battery does not fix the issue, follow the outline below and replace the battery followed by the controller.

 

Error Code 26

Flash saves error

Error 26 is shown there is an error with the controller. Start by resetting the scooter. If that does not fix your issue, update the firmware on the scooter and see if the issue is fix. If none of the above work, replace the controller.

 

Error Code 27

Controller password error

Error 27 is shown when a rental scooter is not properly STLinked or has the wrong firmware version. It can also be caused by someone going through the serial change method. A temporary fix would be to hold the throttle and brake briefly at startup to ignore this error. For a more permeant solution refresh the serial number is the Segway portal. If the scooter still does not work replace the controller.

 

Error Code 31

Program jump error

Error 31 is shown there is an issues with the controller. There isn't much to do other than reseting the scooter, then replacing the controller.

 

Error Code 32

IOT heartbeat timeout

Error 32 is shown on a rental scooter that can no longer detect the IoT device. you will first want to inspect the IoT device and be sure that the connection is free from fraying, clips, kinks, or cuts. If the connection wire is good, unplug and plug it back in and reset the scooter. If the issue still persists, replace the IoT followed by the controller.

 

Error Code 35

Scooter with default serial number

Error 35 is shown when the controller's serial number has the default number. This is usually casued by a firmware. update. This is similar to error 23. The serial number can not be N4GEA1601C0001. To fix this change the controller's serial number using the ninebot launcher app. Otherwise replace the controller followed by the battery.

 

Error Code 37

Charging base or charging cable failure

Error 37 is shown when the charging cable is failing. First try reseting the scooter to see if it fixes the problem. Next check the wiring from the controller to the battery. If any wire are frayed, clipped, has kinks, or cuts Replace the component it belongs to. If all the wiring is good start by replacing the controller, followed by the battery.

 

 

Error Code 39

Temperature sensor abnormality

Error 39 is shown when the battery temperature sensor is reading outside of the normal levels. This could happen from the outside conditions too hot or too cold, or for no reason at all. First check the temperature of the battery with the Segway launcher app. If the battery is too hot let it cool down and if it is too cold move the scooter to a warmer temperature. If the temperature appears to be normal, restart the scooter. If the issue still persist change the battery.

 

Error Code 40

Abnormal temperature sensor of controller

Error 40 is shown the controller has gotten too hot and needs to cool down, but it may also be caused by the sensor coming disconnected or failing. Check the controller wiring for any fraying, clips, kinks, or cuts. Otherwise replace the controller.

 

Error Code 41

Temperature of the motor is abnormal

Error 41 is shown because the motor has gotten too hot and needs to cool down, but it may also be caused by the sensor coming disconnected or failing. Check the motor wiring for any fraying, clips, kinks, or cuts. Otherwise replace the motor.

 

Error Code 45

Scooter flashed with retail firmware

Error 45 is shown when a consumer scooter is updated with rental firmware. Some have reported success with moving the wheel slightly on startup. Otherwise you will want to try flashing the firmware to non-retail firmware.

There is no outline for this error code

 

Error Code 50

Either temperature sensor is outside normal parameters or the rental firmware has not ben setup properly.

Error 50 is shown for one of two reasons. Either the temperature sensor is not reporting a proper value or the rental firmware that is being used has not been set up properly. Rest the scooter to see if that temporarily fixes the issue. For the rental firmware issue you will want to update the firmware to the IoT, the battery, and the controller.

 

Error Code 51
