Before You Start
Please prepare:
Your order number
A photo or video of the error code
A photo of the display
Whether the scooter powers on
Whether the battery charges
Whether the motor engages
Whether the issue happened after riding, charging, storage, transport, crash, impact, rain, water exposure, modification, display replacement, added electronics, or third-party repair
Photos of visible damage, if any
Safety reminders:
Do not continue riding if the scooter shows a persistent error code, overheats, has motor resistance, visible wiring damage, smoke, burning smell, or water exposure.
Do not work on wiring while the scooter is powered on or charging.
Do not open sealed battery components.
Do not force connectors together.
Stop and contact support if unsure.
E30 Communication Error
This means the display is not communicating correctly with the scooter.
Possible causes:
Added electronics or wiring changes
Display connector issue
Loose wiring
Junction box issue
Main cable issue
Controller issue
Step 1 – Check for modifications or added electronics
Check whether any electronics have been added, removed, or modified.
If yes
Remove the added electronics and restore the scooter wiring to its original setup if safe to do so.
Restart the scooter.
If no
Continue to Step 2.
Step 2 – Check the display connector
Turn the scooter off.
If safely accessible, check the display waterproof plug for bent pins, dirt, damage, or poor connection.
If the connector is damaged or pins are bent
Do not force the connector together. Contact support with clear photos.
If the connector looks normal
Reconnect it carefully and restart the scooter.
If the issue is resolved
Monitor the scooter.
If the issue remains
This next step requires further inspection of the display wiring, junction box, main cable, and controller. Please contact support with the photos/videos listed below.
E04 Throttle Error
This means the scooter is detecting a throttle fault.
Possible causes:
Wiring changes
Throttle connector issue
Bent throttle connector pins
Loose wiring
Display main cable issue
Controller issue
Step 1 – Check for wiring changes
Check whether the scooter has been modified or had wiring changed.
If yes
Restore the scooter to its original setup if safe to do so, then restart the scooter.
If no
Continue to Step 2.
Step 2 – Check the throttle connector
Turn the scooter off.
If safely accessible, check the throttle 3-pin waterproof plug for bent pins, dirt, damage, or poor connection.
If pins are bent or damaged
Do not force the connector. Contact support with photos.
If the connector looks normal
Reconnect it carefully and restart the scooter.
If the issue is resolved
Monitor the scooter.
If the issue remains
This next step requires further inspection of the throttle wiring, display main cable, and controller. Contact support.
E05 Undervoltage Protection
This means the scooter is detecting low battery voltage.
Possible causes:
Battery charge is too low
Battery issue
Incorrect P8 voltage setting
Controller issue
Step 1 – Charge the scooter
Fully charge the scooter, then turn it back on.
If the error clears
The battery may have been too low. Monitor the scooter.
If the error remains
Continue to Step 2.
Step 2 – Check whether the battery drains unusually fast
After charging, check whether the scooter shuts down quickly or shows E05 again after only a short flat-road ride.
If yes
The battery may require further inspection. Contact support.
If no
Continue to Step 3.
Step 3 – Check the P8 voltage setting
Check the display P8 voltage setting.
For the Kaabo Wolf King GTR, P8 should be set to 72V.
If P8 is not set to 72V
Set P8 to 72V, then restart the scooter.
If P8 is already set to 72V
Continue to Step 4.
If the issue is resolved
Monitor the scooter.
If the issue remains
This next step requires further inspection of the controller. Contact support.
E02 Motor Hall Error
This means the scooter is detecting a motor Hall sensor fault.
Possible causes:
Loose motor Hall connection
Dirt or foreign material in the connector
Damaged motor cable
Motor issue
Controller issue
The display may indicate whether the fault relates to the front or rear motor:
F-02 indicates a front motor Hall fault.
r-02 indicates a rear motor Hall fault.
Step 1 – Stop riding
Do not continue riding with this error.
Turn the scooter off.
Step 2 – Check visible motor wiring
Check any safely visible motor cable for damage, cuts, crushed sections, or exposed wiring.
If there is visible cable damage
Do not ride the scooter. Contact support with clear photos.
If there is no visible cable damage
Continue to Step 3.
Step 3 – Check the error shown on the display
Look at the display and confirm whether it shows F-02 or r-02.
If it shows F-02
The issue relates to the front motor Hall fault path.
This next step requires further inspection of the front motor Hall connection and controller. Contact support.
If it shows r-02
The issue relates to the rear motor Hall fault path.
This next step requires further inspection of the rear motor Hall connection and controller. Contact support.
If you are unsure what the display shows
Take a clear photo or video of the display and contact support.
