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):
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:
Warning
Faults relative to dtc are only detected if dtc is enabled. In the event of any wheel speed sensor faults or internal bbs faults, dtc is disabled.
Fault indication
Riding modesTraction control (dtc) deactivated
The activation of this (amber yellow) "warning" indicates
that dtc (ducati traction control) has been turned off.
Note
In this case, ducati recommends being very careful
when riding as the vehicle behaviour will be different in
comparison to when operating with the traction control
