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.

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 system
The vehicle is equipped with two dashboards: an lcd (1) located on the
handlebar containing the key indications (speed,
rpm, engine coolant temperature, and clock) and a tft colour display (2) located
in the tank fairing displaying trip
information (riding style set, odometer, consumption, ave ...
Maintenance indicator
This function indicates that the vehicle is about to or has
travelled a distance for which an authorised ducati service
centre should be contacted to have the general maintenance
or oil change performed.
