Dashes Shown Instead Of Speed Indication Or Indicated Speed Is Incorrect - Ducati Diavel Workshop Manual

BBS and DB faults
Check integrity of electric circuit – short-circuit to ground = with the battery cables disconnected, using an ohmmeter,
continuity is detected between the wire tested and ground.
Check integrity of electric circuit – open circuit = with the battery cables disconnected, using an ohmmeter, no continuity
is detected between the two ends of the wire tested.
Gear self-acquisition procedure
The gear self-acquisition procedure must be launched from the DDS instrument. This ensures that the data stored
previously is deleted and enables the BBS to run a new gear acquisition procedure. With the engine running and the
motorcycle in motion:
- Select neutral, pulling the clutch lever completely, dashes "- -" appear in the gear indicator display. Release the clutch,
the letter "C" appears in the display. Keep the motorcycle in this gear for at least five seconds. Then, engage first gear.
- Repeat the above procedure through all the gears, up to sixth gear.
- Downshift through the gears from sixth to first, pulling the clutch lever completely before and releasing after each gear
change.
- Reselect neutral and keep in neutral for at least five seconds, repeatedly pulling the clutch lever completely and
releasing.
- Shift up through the gears from first to sixth, pulling the clutch lever completely.
- Downshift through all gears to neutral and switch off the motorcycle.
- The self-acquisition procedure is complete.

Dashes shown instead of speed indication or indicated speed is incorrect.

Fault codes
DDS: Speed sensor diagnosis -> Max. speed (Max. speed error – signal not correct) – Minimum speed (Min speed error –
signal not correct) – Congruence (Correlation speed error – signal not correct).
Dashboard: the error "Speed sensor" is shown on the service display. The EOBD warning light activates.
Fault indication
If the dashboard does not receive "Vehicle speed" information via the CAN line:
- The error is not indicated on the service display.
- The speed indicator on the dashboard displays fixed dashes.
If:
- DTC is enabled and the ABS detects an error on at least one wheel speed sensor (ABS fault indicator light lit and ABS
disabled).
or
- An error occurs on at least one wheel speed sensor with no ABS.
The error "Speed sensor" is shown on the dashboard service display.
Warning
The dashboard speed indicator also displays fixed dashes if vehicle speed exceeds 299 Km/h.
