Ducati Diavel Service Manual: 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 maintained by the control unit when the speed drops below a specific threshold and when the clutch lever is operated and/or the gearbox is in neutral. The "clutch lever operated" signal is generated by a button on the lever itself, which interacts directly with the engine control unit. The "gearbox in neutral" signal is generated by the gear sensor connected to the bbs, and is transmitted to the engine control unit via the can line (target idle speed with engine stabilised at operating temperature is 1,350 rpm). The co value for each cylinder, always with engine stabilised at operating temperature, must be within 0.4 And 1.4 In volume percentage.
Throttle valve aperture regimens
The rider may select between four different riding modes (sport, touring, urban) from the tank dashboard and via the handlebar controls. Each riding mode contains three configurable throttle valve opening strategies (the engine control calibration parameters, in other terms the maps for quantity of fuel injected and ignition timing advance, are the same for all). This allows the rider to adapt power delivery and maximum power as follows to suit personal preferences:
- 162 High (torque delivery tuned to give the bike a sports character, with maximum power of 162 hp available (high for french and japanese market))
- 162 Low (torque delivery tuned to give the bike a tourist character, with maximum power of 162 hp available (middle for french and japanese market))
- 100 Hp (softened torque delivery with maximum power limited to 100 hp (low for french and japanese market))
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 throt ...

Refitting the rear-view mirrors
Start the screws (2) in their thread on the rear-view mirrors (1), inserting
the washers (4) as shown in the picture.
Insert the rear-view mirrors (1) in the u-bolts (3).
Tighten the screws (2) to a torque of 25 nm +/-10% (sect. 3 - 3, Frame torque
settings).
Warning
The left rear-view ...
Hands free key (hf) not recognised
The activation of this (amber yellow) "warning" indicates
that the hands free system does not detect the active key
(1, fig. 62) Near the vehicle.
Note
In this case, ducati recommends checking that the
active key (1, fig. 62) Is near the vehicle (and has not been
lost) and that it f ...
Refitting the radiator
The reassembly procedure is the same for both radiators.
Check for the nuts with clips (8).
Refit the rh radiator (13) on the frame and tighten the screws (4) and (5)
with the spacers (6) to a torque of 10 nm
+/-10% (sect. 3 - 3, Frame torque settings).
Connect the connections of ...
