Introduction
The on/off switch on the handlebar is used to switch the dashboard on and off, if a key has been detected, and start the engine.
With the switch turned to "run off" (centre position), pushing downwards switches the dashboard on or off (activating the button inside the switch).
Wiring diagram

The button inside the on/off switch receives 12 volt power directly from the battery via the main 30 a fuse. When pressed, it sends the 12 volt power to the hands free system, which detects activation of the button. On/off switch pin 8, light blue wire (lb), on/off switch pin 5, red wire (r).

Error codes
The hands free system generates no fault code in the event of a fault of the on/off switch on the handlebar.
Electrical characteristics and checking component
The switch receives 12 volt power directly from the battery via the main 30 a fuse.
Check for 12 volts on pin 5 of the switch.
Check for 12 volts on pin 6 of the hand free system side connector with the switched pressed. The voltage measured must be 0 volts when the switch is not pressed.
In the event of fault
In the event of a fault of the on/off switch on the handlebar, the button integrated into the hands free system may be used instead.
Installation location

The image shows the location of the on/off switch, near the throttle grip on the right hand side of the handlebar.

Refitting the timing gears
Before reassembling the removed parts, check timing gears (13) for wear.
Change, if necessary.
Important
The timing gears (13) must always be renewed as a pair.
Refitting is the reverse of removal.
Warning
When introducing the driven gear (b) check that the tongue (15) is
correctly fitted o ...
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 throttle valve
position sensor)
One injector per cylinder installed downstream of throttle valve
On ...
