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 ...

Lap registration function
This function describes the "lap" time registration.
If the function is activated (see "lap activation/deactivation
description), the lap time can be registered as follows:
Pressing the flash headlight button (11, fig. 12) The first
time starts the "lap timer" for ...
Refitting the cooling system hoses and unions
Position the pump/radiator sleeve (22) and the radiator/radiator sleeve (23).
Fit sleeve (23) and sleeve (22) to their corresponding fittings (n) and (o), and
bring them fully home on collars (p).
Note
Sleeves (23) and (22) must be oriented so that the grooves (q) match the
tabs (r) on fitt ...
Alternator
It is equipped with a 12 v, 430 w generator, consisting of a fixed element
(stator, a) located on the generator cover and
of a movable element (rotor, b) fixed to the crankshaft.
Note
To check the battery charging system for faults, use the dds diagnosis
instrument and follow the instruct ...
