Professional inspection is recommended.
Urgency
High
Quick answer
Error 15 on a Xiaomi scooter: the brake lever was not at rest at power on. Release it, check it springs back by itself and switch on without touching it. If the code stays, do not ride: it is the braking system and the service centre must check it.

Brake lever return
No special tools

- Result that matters:
- that the lever returns to rest unaided.
- If it sticks or has play:

What it means
For Xiaomi, code 15 is a brake lever fault: it does not return to its original position at power on. The dashboard reads the lever sensor at startup; if it is not at rest, drive is blocked. Xiaomi lists squeezing the brake while switching on and a sensor wire broken after the front connector was removed, and its fix adds a stuck lever, a damaged lever, a loose harness and the dashboard circuit. The code does not prove the lever is broken, but it involves braking and on the 6 Pro riding is not available.
