Hi
I think that you will need some official Segway dealer support.
Your Segway i180 maintains internal logs.
If you have a critical error, or a collection of less critical errors, then the machine will go in to shut down, and display the code you describe.
( Bad batteries do not usually cause this ).
ONLY a Segway dealer can assist you.
They can download the logs and clear that file.
Sometimes if there's simply been a collection of less critical errors, then merely clearing the log file will clear the error condition.
Other times if there's been a critical ( or dangerous ) error, then service will be required.
Good Luck
Michael
