KuKirin G2 Master 2025 Error Codes: Understanding the Alerts

The KuKirin G2 Master 2025 is equipped with an advanced electronic system capable of automatically detecting certain malfunctions.

When an issue occurs, a KuKirin G2 Master 2025 Error Code may appear directly on the display. These error codes help identify the source of the problem quickly, allowing riders to diagnose faults before they lead to more serious damage.

In this guide, we cover the main KuKirin G2 Master 2025 Error Codes and explain the recommended solutions for each situation.

Error Code E001 – Rear Motor Hall Sensor

The E001 error code indicates a problem related to the rear motor Hall sensor.

This sensor allows the controller to accurately determine the motor position and manage acceleration and wheel rotation correctly.

If this error appears, it is recommended to swap the front and rear motor connections to identify the source of the issue.

If the error remains after swapping the connections, the controller is usually the cause.

If the error disappears, the rear motor is defective and should be replaced.

Error Code E002 – Throttle

The E002 error code indicates a throttle malfunction.

In this situation, the scooter may lose acceleration or fail to respond correctly when the throttle is pressed.

The problem is generally caused by the throttle itself or by a connection issue.

The recommended solution is to replace the throttle assembly and test the scooter again. On the KuKirin G2 Master 2025, the throttle assembly also includes the key ignition switch.

Error Code E003 – Controller Communication

The E003 error code indicates a communication problem between the display and the controller.

The controller acts as the brain of the scooter, managing communication between all electrical components.

When this error appears, the controller is no longer receiving information correctly from the dashboard.

In most cases, replacing the controller resolves the issue.

Error Code E005 – Battery Undervoltage

The E005 error code indicates that the battery voltage is too low.

This usually means the battery does not have enough charge to power the scooter properly.

The first step is to fully recharge the battery and then test the scooter again.

If the problem persists after a complete charge, it may be necessary to inspect the battery or charger.

Error Code E006 – Display Reception Fault

The E006 error code indicates that the display is no longer receiving information correctly from the controller.

This issue may be caused by either the display itself or the controller.

The recommended solution is to inspect all connections and replace the display and/or controller if necessary.

Error Code E007 – Display Communication Fault

The E007 error code indicates that the display is not transmitting information correctly to the scooter’s electronic system.

As with E006, the first step is to check all connectors and wiring.

If the issue remains, replacing the display or controller is generally required.

Error Code E009 – Controller Overheating

The E009 error code indicates that the controller has exceeded its safe operating temperature.

This can happen after prolonged acceleration, steep climbs, heavy loads, or sustained high-speed riding.

If this error appears, stop using the scooter and allow the controller to cool down.

It is also important to verify that the controller is properly mounted and that heat dissipation is functioning correctly.

Error Code E0011 – Front Motor Hall Sensor

The E0011 error code is related to the Hall sensor located inside the front motor.

Like the rear motor Hall sensor, it helps the controller manage motor operation accurately.

To diagnose the issue, swap the front and rear motor connections.

If the error remains, the controller is likely defective.

If the error disappears, the front motor should be replaced.

Error Code E0013 – Controller Fault

The E0013 error code indicates an internal controller malfunction.

The scooter’s electronics have detected a fault within the controller itself.

In most cases, replacing the controller is the recommended solution.

After installation, restart the scooter and verify that the error has disappeared.

Error Code E0017 – Controller Communication Fault

The E0017 error code indicates a communication issue involving the controller.

The display and controller are no longer exchanging information correctly.

The problem may originate from the display, the controller, or a loose connector.

Checking all connections is recommended before replacing the display or controller.

How to Prevent KuKirin G2 Master 2025 Error Codes
