How to use this site
- Note the exact code on your display, including letters and leading zeros.
- Look it up above and follow the steps in order: most codes clear after a proper restart and a connector check.
- If the page says "dealer needed", stop tinkering. Motors and batteries are not user-serviceable and opening them voids warranty.
