BBS and DB faults
Warning
DTC is disabled in the event of a wheel speed sensor error.
Wiring diagram

PIN numbering of wiring harness side BBS unit connection.
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.
