Ducati Diavel Service Manual: Operating principle of dtc

The bbs receives the front and rear speed information from the abs over the can. Then, the bbs sends the vehicle speed information to be displayed on the dashboard over the can.

If the tangential speed of the rear wheel exceeds the tangential speed of the front wheel by a given percentage, this indicates that the rear wheel is wheelspinning excessively. At this point the dtc intervenes, requesting the ecu to reduce engine torque. A number of other sensors are also included inside the bbs to determine if the vehicle is wheeling, in which case the dtc will not intervene until a predetermined vehicle speed is reached. To ensure that the ducati traction control functions correctly, never fit tyres other than those authorised by ducati. On the diavel there are 8 different dtc levels (from 1 to 8):

  1. Sporty riding on a road for expert users and on track. It is the default setting of the sport riding mode.
  2. Riding on a road for expert users (sport-touring).
  3. Normal riding on a road it is the default setting of the touring riding mode.
  4. Normal riding on a road for less expert users (touring 2).
  5. Riding in town it is the default setting of the urban riding mode.
  6. Riding in town for less expert users (urban 2).
  7. Riding with moderately wet ground (wet).
  8. Riding with wet ground (rain).

The dtc may be disabled by the rider.


The dashboard specifically indicates if dtc is enabled or if it has been disabled by the rider.

In the event of internal bbs faults relative to the dtc function, the dds shows the following messages relative to bbs/dtc diagnosis:
