Hi there! Welcome to the ebikesforum.

Error code 09 on the Bafang is a Phase short circuit or Open circuit. Here's a link to the full list of Bafang Error Codes: https://ebikesforum.com/threads/bafang-drive-system-display-error-codes.127/

I would suggest to check your wiring very carefully to make sure that everything is connected properly. Also check to make sure none of the wires have got caught up in anything and shorted out together.

How did you go with this, did you ever find the loose wire or a fix to error #9 on the bafang?
