The dds (diagnosis ducati system) indicates all active errors and all inactive but stored errors gathered by the bbs. A simplified summary of the active errors is also shown in the master dashboard service display when the dashboard is switched on. Simultaneously, the eobd warning light is also activated, independently of the types of the errors themselves. In the event of more than one active error, the errors are shown cyclically on the service display for 3 seconds each.
In the event of a can line fault (can off), the dashboard cannot transmit data and the electrical system behaves as follows:
If the can line fault is no longer present (fault resolved), normal operation is resumed and the can error disappears from the tank dashboard.
Other faults relative to the can line and indicated on the tank dashboard and by activation of the eobd warning light, are described as follows:

Dashboard warning and indicator light key (some of these are used to indicate faults in the electric - electronic system):
Warning
When diagnosing one of more elements in the electric - electronic system, also check that there are no error codes indicating can line faults. If any error codes relative to can line faults are noted, the relative fault must always be resolved as it may be correlated with other specific faults.
