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:
If:
Or
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.
Warning
Dtc is disabled in the event of a wheel speed sensor erro

Checks
For diagnosing wheel speed sensors, consult the section relative to diagnosing the abs unit.
Check the integrity of the electrical circuit and connections (short-circuits to ground, short-circuits to vdc, open circuits).
If the above test did not identify the problem, contact ducati.
Note
Check integrity of electric circuit - short-circuit to vdc = with dashboard on, using a voltmeter, a voltage is measured between the wire tested and ground.
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.
Propagation of wheel speed signals and generation of vehicle speed signal
The diagram illustrates how the vehicle speed information is generated and how it is transmitted to the dashboard.
Using the replicated rear wheel speed signal and the circumference of the wheel itself, the bbs unit calculates the vehicle speed (2 in diagram). This parameter is used by the ducati traction control (dtc) function together with the front wheel speed and the circumference of the front wheel itself, in order to implement engine torque limiting strategies when required.
The vehicle speed calculated by the bbs is transmitted over the can line (3 in diagram) and acquired by the dashboard, which displays the speed information accordingly.
Refitting the front footrests
Note
The assembly of the front footrests is described only for the right one
(2) but it is the same also for the left one.
Place the spring (4) bringing the end (a) onto the footrest (2).
Place the footrest (2) in the correct position, by inserting the end (c) of the
spring (4) in the hole ...
Total distance covered indicator: "odometer"
This function shows the total distance covered by the vehicle (in km or miles
depending on the specific application).
At key-on the system automatically enters this function.
The odometer reading is stored permanently and cannot be reset.
If the distance travelled exceeds 199999 km (or 19 ...
Refitting the timing belt driveshaft pulleys
To fit the circlip (10) in the driveshaft seat, use the tool code 88713.2834.
Install the inner spacer (17) on the driveshaft, taking care to align the
notch in the spacer with the slot for the woodruff
key.
Fit the first woodruff key (16) on the timing belt driveshaft.
Locate the ...
