Ducati Diavel Service Manual: Introduction to the "hands free" system
The hands free system allows the rider to start the engine without physically using the ignition key. The ignition key merely has to be in the vicinity of the motorcycle, such as in the rider's pocket, for example, in order to use the vehicle.
Compared to the standard ignition switches the hands free system allows having the hands completely free during usual actions (i.E. Engine ignition/stop, dashboard switch on/off) and engaging/disengaging the steering lock.
The electric steering lock used with the hands free system locks the handlebar either in the fully right or fully left position, offering greater versatility when parking.
The hands free system consists of the following components:
- Hands free system with integrated button for switching the dashboard on and off and for locking and releasing the electric steering lock (henceforth indicated as "on/off button or switch")
- Antenna
- Electric steering lock (integrated into hands free system)
- Active key (with internal battery and transmitter) and passive key (with internal transponder)
- Button on handlebar for switching dashboard on and off and for locking and releasing the electric steering lock
The hands free system is connected to the other computers (nodes) on the motorcycle and to the dashboard via the can line. Through this connection, the system can either enable (key detected and recognised) or disable (key not detected or not recognised - immobilizer function) engine start. Any relevant information messages, such as battery key low warning or no key warning, are displayed on the tank dashboard.
Operating principle
Introduction
The hands free system features two separate on/off buttons, either one of
which may be used as preferred by the rider.
For practical reasons, we recommend using the button on the ha ...

Disassembly of the gearbox shafts
Place the shaft in a vice in such a way as to facilitate the disassembly
operations.
Important
Take care not to invert the positions of the shims on reassembly:
this would potentially lead to jamming when using the gear selector control,
making it necessary to reopen the engine
crankcase.

The battery charging circuit and power distribution
On the diavel, the +15v (key on power) voltage does not come from a
conventional ignition key, but from pin 30 of the
hands free relay. This relay is switched to closed state by the hands free unit
when the latter enables power on for the
ignition and engine. The hands free relay receives +30v ...
Checking and adjusting the valve clearances
Note
For clarity, the figures show the engine removed from the frame.
Move the piston of the cylinder being checked to tdc of the power stroke: in
this condition, all the valves are closed and
the timing shafts come in neutral position and, therefore, free to rotate; check
to the valve cl ...
