Master Kukirin G2 troubleshooting with our expert tips—perfect for electric scooter enthusiasts and everyday riders alike.

I. E-000: Motor Jam Error

Problem Cause: Motor jamming due to foreign objects blocking the wheels or excessive pressure on the motor.

Solution:

Immediately turn off the Kukirin G2 electric scooter and check if the wheels are entangled with stones, cables, or other debris.

Remove the obstacles carefully, then restart the scooter to resume normal use.

II. E-001: Battery Overvoltage Error

Problem Cause: Battery voltage exceeds the normal operating range.

Solution:

First, let the Kukirin G2 scooter sit idle for 2 days to allow the battery voltage to drop naturally.

If the error persists after idle time, use the dedicated reset software to reset the system.

III. E-002: Battery Undervoltage Error

Problem Cause: Low battery voltage, or issues related to the battery, charger, or controller.

Solution:

Confirm the purchase date of your Kukirin G2. If it’s an older model, download the OTA software for an upgrade via this link: https://asset.szrnd.net/app/reset.apk (Android devices only).

For non-older models, measure the actual battery voltage: if the voltage is abnormal, the battery is faulty and needs replacement.

If the battery voltage is normal, the fault lies with the controller—replace the controller directly.

IV. E-003: Controller Error

Problem Cause: Controller malfunction or loose connection of the main cable.

Solution:

Turn off the power, locate the connection port between the main cable and the controller, unplug it, then reinsert firmly to ensure a secure connection.

Restart the Kukirin G2; if the error still appears, replace the controller.

V. E-004: Throttle Error

Problem Cause: Loose connection of the throttle or throttle component failure.

Solution:

Check the connection port between the throttle and the main cable, unplug it, then reattach and secure it.

If the error persists after reconnection, replace the throttle accessory.

VI. E-005: Brake Lever Error

Problem Cause: Loose connection of the brake lever or brake lever component failure.

Solution:

Unplug the brake lever’s connection port, clean any dust from the interface, then reinsert tightly.

Restart the Kukirin G2 electric scooter; if the error remains, replace the brake lever.

VII. E-006: Serial Communication Failure

Problem Cause: Poor contact of the main cable or controller malfunction.

Solution:

First, reinsert the main cable port to ensure no loose connections.

If ineffective, replace the main cable for troubleshooting.

If the error persists after replacing the main cable, further replace the controller.

VIII. E-007: Hall Sensor Error

Problem Cause: Malfunction of the motor’s Hall sensor or controller abnormality.

Solution:

First, unplug and reinsert the connection terminal between the motor and the controller. For older Kukirin G2 models, try installing the repair software via this link: http://asset.szrnd.net/app/2018_fix_e7_ota.apk (Android devices only; not applicable for new models).

If the software update doesn’t work, replace the motor directly.

If the error still occurs after motor replacement, the controller is rarely the cause—replace the controller for further troubleshooting.

IX. Blinking 88: Motor Overheating Error

Problem Cause: Excessively high motor temperature due to continuous high-power load.

Solution:

Immediately turn off the scooter, let it sit idle for a few minutes to cool down the motor, then restart—this usually resolves the error automatically.

If the error persists after cooling, use the reset software to reset the system.

If resetting doesn’t work, replace the motor for further inspection.

Always ensure the Kukirin G2 electric scooter is powered off before any operation to avoid electric shock risks.
