Wiring Diagram; Stop Light Not Working - Ducati Diavel Workshop Manual

BBS and DB faults
Fault codes
DDS: displays a fault code described in the description of the ABS system.
Dashboard: no fault code displayed.

Wiring diagram

Checks
The ABS fault indicator indicates the occurrence of one or more faults in the antilock brake system, or if the system itself
has been disabled by the rider, using the relative control. The signal causing activation of the ABS fault indicator when the
antilock brake system is disabled, comes directly from the ABS unit, and the information is transmitted over the CAN line
by the BBS unit, so that it may be acquired by the dashboard, where the indicator itself is located.
Diagnose 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.

Stop light not working

Fault codes
DDS: Stop light diagnosis -> Stop light error (generic stop light malfunction indication).
Dashboard: the error "Stop light" is shown on the service display. The EOBD warning light activates.
