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 ...

Dashboard diagnosis
This function identifies any abnormal vehicle behaviours.
The dashboard activates any abnormal vehicle behaviours in real time (errors).
At key-on (at the end of the check) one or more "errors" are displayed in red
(only if they are active).
When an "error" is triggered, the indication (r ...
Checking the battery charging system
To check the current flow of the recharging circuit, use the "dds" diagnosis
instrument, which is equipped with an
inductive clamp-type amperemeter: refer to chapter "testing the battery charging
system", sect. 6 - 11
With the dds diagnosis instrument you can determine the engine rpm required ...
Refitting the front sprocket
Grease the o-ring (16) and install it on the front sprocket spacer (15).
Fit the spacer, from the o-ring side, on the secondary shaft and drive it fully
home against the inner ring of the bearing.
Check that the splines of the gearbox secondary shaft and the sprocket are in
perfect condi ...
