Ducati Diavel Service Manual: Electrical power for lighting and signalling devices

The front and rear running lights consist of led units with light conduits. As a result, the light source is not visible as the light is diffused through the surface of the light conduit.

To access the tail light - turn indicators unit, remove the seat as described in sect. 5 - 3, "Removal of the seat" and the tool tray cover as described in sect. 7-17, "Removal of the tool tray".

The bbs and the dash board unit provide electric power to the lighting and signal devices, which therefore have no conventional power supply passing via a fuse and no electric switchgear set on the handlebar. Commands for the lights and signals are in fact sent to the control units, which then activate the relative lighting devices. The following table indicates the types of devices used, the type of power supply and whether or not the devices are testable.

Device type

Power type

Function

Front led turn indicators, commanded directly from dash board Pwm without specific fuse Not testable
Rear turn indicators with incandescent bulbs, commanded directly from bbs 12V without specific fuse Bulb function may be tested
Number plate light with incandescent bulb commanded directly from dash board Pwm without specific fuse bulb function may be tested
Low beam lights with incandescent bulbs 12V with fuse Bulb pwm
High beam lights with incandescent bulbs 12V with fuse Bulb function may be tested
Front and rear led running lights, commanded directly from bbs 12V without specific fuse Device function may be tested using an external 12v power source
Led stop light, commanded directly From bbs 12V without specific fuse Device function may be tested using an External 12v power source

As soon as you start the engine the low beam turns on automatically. In key-on condition and engine off it is possible to turn on the high and low beams that will switch off after 60 seconds if the engine is not started: in key-on condition the headlights are off, in key-on and engine running the headlights turn on automatically and in key-on it is possible to turn them on with the lh switch.

Ground connection locations
The negative cable, which is normally connected to the negative pole of the battery, is fastened to the crankcase. From here, the cable branches off and splits up within the electrical system to ca ...

Injectors
Introduction The injectors used on the diavel are top feed units, meaning that fuel is fed into the top of the injector itself. The injectors contain a winding which raises a needle when electrically energised. This opens the atomiser nozzle, through which pressurised fuel is dispensed, gener ...

Refitting the exhaust system
Refit the heat guard on the manifold (10) by tightening the nuts (9) to a torque of 10 nm +/- 10% (sect. 3 - 3, Frame torque settings). Position the vertical exhaust manifold (22) on the vertical cylinder head with the gasket (23). Tighten the fixing nuts (21) to a torque of 10 nm +/- 1 ...

Refitting the intake manifold and coolant union
Apply prescribed threadlocker to the fitting (12), start it with seal (24) and tighten it to a torque of 2.5 Nm (min. 2 Nm - max. 3 Nm) (sect. 3 - 3, Frame torque settings). Install the pipe (b) and tighten the clamp (a) to the torque of 1 nm +/- 10% (sect. 3 - 3, Engine torque settings). ...
