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 ...

Abs diagnosis
Note
The on-screen icons used during this procedure are explained in a table at
the end of this section.
If the abs system is not working correctly, system diagnosis is possible
through the dds diagnosis instrument.
Turn on the dds diagnosis instrument (1) referring to the paragraph "tester ...
Disassembly of the rear brake control
The brake master cylinder is supplied only as a complete unit; internal
components cannot be replaced.
To disassemble the master cylinder's outer parts, follow the indications given
in the exploded view at the beginning of this
section.
If the bush (10) inside the brake pedal (6) needs to ...
Refitting the camshafts
If the stud bolts (2) were removed, apply the recommended threadlocker to the
short end of the stud bolts (2), i.E. The
end that is to be screwed into the cylinder head. Tighten the stud bolts (2) to
a torque of 10 nm (min. 9 Nm - max. 11
Nm) (sect. 3 - 3, Engine torque settings).
