Scooter Diagnostic Functions
Your Scooter Controller provides diagnostic information in the form of flash-codes. The first LED on the battery
indicator flashes to indicate a problem has been detected. On switching on, the controller conducts a
diagnostic test. If there is a fault, the first lamp/LED in the battery indicator will flash a sequence of flashes to
indicate what the fault is. There will be two groups of flashes separated by a 2 to 3 second pause. Count the
number of flashes in each group and decode the fault using the table below.
