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:

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 ...

Inputs and outputs of engine control unit and connection to can network
The diagram illustrates the inputs and outputs for the engine control unit. The signals from the brake buttons, the exhaust by-pass valve command signal and the gear sensor signal are transmitt ...

Refitting the front brake system
While refitting the system, pay special attention to the orientation of the pipe couplings (24) on the pump and the pipes (13) and (20) on the callipers (9) and (18). Warning If incorrectly positioned, the hose can affect brake operation and foul moving parts. Position the hose as shown in th ...

Reassembling the water radiator unit
The procedure is the same for both radiators. Check the presence of clips (1) at the positions of the external coolant radiator cover (23). If removed, fit the front turn indicator (32) on the cover (23) and tighten the screws (27) to 2 nm +/- 10% (sect. 3 - 3, Frame torque settings). No ...

Headlight control
This function allows you to reduce current consumption from the battery, by automatically managing headlight switchingoff. At key-on, the high beam and low beam lights are off. When the engine is started, the low beam lights turn on automatically; from this moment, "normal" operati ...
