Ducati Diavel Service Manual: Introduction to the engine control system
The engine control system used on the diavel consists of the following elements:
- Ride-by-wire system (motorised throttle valves with electric actuator, throttle grip position sensor and throttle valve position sensor)
- One injector per cylinder installed downstream of throttle valve
- One coil per cylinder, in spark plug bore
- Two oxygen sensors (one per cylinder, installed on each exhaust manifold)
- Two absolute pressure (map) sensors installed downstream of throttle valve (one per cylinder connected to each intake duct)
- One three-way catalytic converter for exhaust gas post-treatment
The system also includes conventional sensors for water and air temperature, engine speed-timing etc.

Programming/reprogramming keys
The dds diagnosis instrument is required in order to programme/reprogramme
the keys. The key programming procedure
is launched from this instrument.
To start the key programming/reprogramming pr ...
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 generator cover
Note
This operation is described for an engine removed from the frame since all
reassembly procedures are easier with the
engine on the bench.
Disconnect the connector (a) from the generator cable.
Unscrew the two retaining screws (7) of the centre cap (6) over the end of
the cranksh ...
Main bearings
The main bearings have are of the angular contact type with offset inner
races so that the balls transmit loads from one
groove to the other along straight lines at an angle to the axis of the bearing.
The angle-contact ball bearings are
designed for bearing combined loading (radial-axial load ...
