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 ...

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 ...
Adjusting the steering head bearings
Note
To adjust the steering bearing clearance, follow what is described in
sect. 4 - 3, Adjusting the steering head bearings.
If the problems found are not solved, check the wear of steering bearings (6)
and replace them, if necessary, as described
in paragraph "removal of the steering head c ...
