How to use this site

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