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))

Identification data
All ducati motorcycles have two identification numbers, for
frame (fig. 1) And engine (fig. 2).
Note
These numbers indicate the motorcycle model and
should be quoted when ordering spare parts.

Lubricating cables and joints
Check the outer sheath of the throttle control and cold start
lever cables for damage at regular intervals. The outer plastic
cover should not be flattened or cracked. Operate the
controls to make sure the inner cables slide smoothly inside
the outer sheath: if you feel any friction or catching, ...
