Troubleshooting TFT Display Errors on Kaabo Electric Scooters

• Ensure all phase wires are securely connected by unplugging and then re-plugging them.
• Inspect the motor phase wire for any signs of damage or defects.
• Perform roll testing to further diagnose the issue.

• Ensure all hall sensor wires are securely connected by unplugging and then re-plugging them.
• Inspect the hall sensor wire for any signs of damage or defects.

Scenario:
If a GTR scooter displays "ERROR CODE 2" and the motor exhibits resistance or a notchy feeling when spun by hand, follow these troubleshooting steps:

• Disconnect the phase and hall sensor wires (blue, green, yellow, and the 5-6 pin connector it's paired with).
• Spin the motor again. If the notchy feeling disappears, it indicates a controller issue, with a likelihood of 99%.
• An example case illustrating this issue is observed in Cruiser motor cables burning, as demonstrated here: Video Link

• Check all connectors at the handlebar are connected properly.
• Ensure no pins are broken in the connectors.

• Check if the settings are configured at the correct voltage.
• Measure the voltage at the battery to ensure it falls within the correct working voltage range. Refer to this video link at the specified timestamp for guidance: https://youtu.be/_mPI3we8aJk?si=k9uRzY-gxwAyhWSK&t=236.

• Check that all connectors are plugged in properly.
• Additionally, conduct a roll test with the motor phase both plugged in and unplugged.

• Check all connectors at the handlebar are connected properly.
• Ensure that no pins are broken.

• Ensure that the temperature on the display is cooling below the set temperature protection value.

• Check all connectors from the controller to the handlebar area are connected properly.
• Ensure that all pins are correctly connected.
