In plain English

Brake levers have sensors that tell the motor to stop when you brake. This code means the signal looks wrong. Check your brakes work properly before riding.

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.

1Check the brake levers spring backFree Squeeze and release each brake lever. Both should snap fully back. A lever that stays slightly pulled can make the scooter think you're braking.
2Switch off and restartFree Turn the scooter off, wait 30 seconds, then turn it back on. If the code clears, note what you were doing when it appeared, in case it comes back.
3Contact support or a service centerShop job If the code stays after these checks, stop riding and contact the brand's customer support or an authorized service center. Don't open the deck, battery, controller or motor: most scooter batteries and controllers aren't user-serviceable.
