Error 10 on the Segway KickScooter P65 means “BLE Bluetooth communication error.” Most likely cause: the display, controller and battery have stopped talking to each other properly. Try this first: switch off and restart.
The parts of the scooter share data over a cable through the stem and deck. This code means that link was lost. A restart sometimes clears it. If it stays, support can check the connections.
Step-by-step checklist
Work from the top. Steps go from free and easy to shop jobs. Switch the scooter off before touching any connector. Tick each step as you go. Your progress is saved on this device.
When it's time for a shop: if you've worked through every step and the problem is still there, contact the brand's support or an authorized service center. Bring your notes on when it happens, plus the code.
