11.1 Diagnosis and fault repair

The electronic system offers diagnostic information to support the
technician during the recognition and rectification of faults on the
scooter.
The electronic system reacts differently depending on the seriousness
of the fault and its effect on user safety. It can, for example:
•
Display the error code as a warning and allow both driving and
normal operation to continue.
•
Display the error code, stop the scooter and prevent further
travel until the electronic system has been switched off and
switched on again.
•
Display the error code, stop the scooter and not permit further
travel until the fault has been rectified.
You can find detailed descriptions of individual error codes, including
possible causes and fault repair, in 11.1.2 Error codes and diagnostic
codes, page 53.
