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 ...

Warning
Clutch fluid will damage painted surfaces if spilled on them. It is
also very harmful if it comes into contact with the skin or
with the eyes; in the case of accidental contact, wash the affected area
thoroughly with plenty of running water.
