Gear Indicator Display On Dashboard Shows Dashes, Engaged Gear Not Displayed Correctly, Idle Speed Irregular With Gearbox In Neutral - Ducati Diavel Workshop Manual

BBS and DB faults
Test turn indicator reset button function. When the button is pressed, there must be continuity between its two electric
terminals (PIN 3 and PIN 1).
Check that there is a voltage of 5V on PIN 1 of the turn indicator reset button arriving from dashboard PIN 17.
Check the integrity of the electrical circuit and connections (short-circuits to ground, short-circuits to Vdc, open circuits).
If none of the aforementioned tests identifies the problem, replace the dashboard.
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.
Gear indicator display on dashboard shows dashes, engaged gear not displayed correctly, idle speed irregular
with gearbox in neutral.
Fault codes
DDS: Gear sensor diagnosis -> Short circuit to ground or open circuit (S.C. GND or C.O.) – Short circuit to Vdc (S.C. Vdc)
– Congruence (Generic error – signal not correct).
Dashboard: The error "Gear sensor" is shown on the service display. The EOBD warning light activates.
Fault indication
If the dashboard receives the "Gear" error information via the CAN line:
- The error is indicated on the dashboard service display.
- The dashboard shows dashes in the gear indicator display instead of the gear engaged.
If the dashboard does not receive the gear or neutral engaged information via the CAN line:
- The error "Gear sensor" is not indicated on the dashboard service display.
- The dashboard causes the neutral indicator to flash.
If the dashboard receives incorrect gear engaged information (flashing dashes) via the CAN line with the engine running:
- The dashboard shows flashing dashes in the gear indicator display.
Warning
It is possible that the gear engaged or neutral engaged information is not being generated because the gear position
self-acquisition procedure has not been performed (gear sensor not initialised).
