Ducati Diavel Service Manual: Inputs and outputs of engine control unit and connection to can network
The diagram illustrates the inputs and outputs for the engine control unit. The signals from the brake buttons, the exhaust by-pass valve command signal and the gear sensor signal are transmitted over the can line.
1I emergency engine cutout switch
2I start button
4I side stand button
6I clutch button
7I battery voltage for congruence verification
8I power from ride-by-wire relay (etv)
9I oxygen sensor for horizontal cylinder
10I oxygen sensor for vertical cylinder
11I map sensor for horizontal cylinder
12I map sensor for vertical cylinder
13I main throttle grip position sensor
14I secondary throttle grip position sensor
15I main throttle valve position sensor
16I secondary throttle valve position sensor
17I engine temperature sensor
18I air temperature sensor
19I oil pressure switch (has no effect on any engine control strategy, but information is sent to dashboard via can line)
1U vertical and horizontal cylinder fuel injector
2U vertical and horizontal cylinder coil
3U electric ride-by-wire
4U injection relay (powers fuel pump, injectors and coils)
5U starter motor relay command
6U radiator fan relay command
7U ride-by-wire relay command
8U oxygen sensor heater for vertical and horizontal cylinder
1C connection with can network
Specific operating strategies
Idle speed
No electric motor is used for idle speed regulation (bypass is modulated
instead with the throttle valve), as idle speed
control is effected by the ride-by-wire system. Idle speed is ma ...

Removal of the clutch
Note
For clarity, the figures show the engine removed from the frame.
Undo the fixing screws (1) and remove the ring (2) and the springs (3) from
the pressure plate (4).
Slide the pressure plate (4) paying attention to the circlips (6).
Remove the clutch control pin (14) and the ...
Fuel system circuit
The fuel system circuit consists of:
An electric pump, driven by the injection relay, which is in turn
controlled by the ecu (engine control unit)
A fuel filter
A pressure regulator
Two injectors (one per cylinder, located downstream of throttle valve)
The plastic mounting shown in t ...
Checking the engine timing
Set the engine to the configuration described for the "checking and adjusting
the valve clearances", previously indicated.
Install tool 88765.1188 (G) in the spark plug bore to determine the piston tdc,
the gauges (h) on the tool 88765.1518
And the timing check tool (degree wheel (l) 887 ...
