8.3 Fault and diagnosis codes

If there is an electrical fault, this is displayed by the fact that the power pilot
light (11; status display) in the operating unit blinks.
This displays an error code which allows an approximate fault diagnosis.
The diode (11) then flashes in a particular blink sequence.
The electronics system is able to correct some errors automatically.
•
Switch the Scooter off, wait five seconds, and then switch it on again.
The test checks whether the error can be automatically rectified by the electronics, and if necessary
deactivates the blinking status display at the operating unit.
If the error cannot be rectified, limit the source of error using the "Status display error codes" table (see
chapter: 8.3.1 page: 13).
