Introduction
The clutch button is located on the clutch lever. Together with the signal from the side stand button and the neutral signal generated by the gear sensor (transmitted to the engine control unit over the can line), the clutch lever position signal is used to enable or disable engine start.
The following table indicates the only conditions in which starter motor
activation and, as a result, engine start, are
permitted:
If a gear is engaged with the side stand down, however, the engine switches off.
The engine control unit recognises the idle speed state when engine speed drops below a certain threshold and when the ecu itself receives the clutch lever pulled and/or gearbox in neutral signal (generated by gear sensor).
Component assembling position
The clutch button is located under the lever.

In the event of fault
In the event of a clutch button fault, the operating conditions described in the introduction are not met.
Fault codes generated and possible correlated faults
The engine control unit generates no fault code in the event of a clutch button fault.
No errors are indicated on the dashboard.
Possible correlated faults: the safety conditions required to enable engine start are not met, incorrect idle speed (target idle speed is 1350 rpm with engine stabilised at operating temperature). Check:
Note
Check integrity of electric circuit - short-circuit to vdc = with dashboard on, using a voltmeter, a voltage is measured between the wire tested and ground
Check integrity of electric circuit - short-circuit to ground = with the battery cables disconnected, using an ohmmeter, continuity is detected between the wire tested and ground
Check integrity of electric circuit - open circuit = with the battery cables disconnected, using an ohmmeter, no continuity is detected between the two ends of the wire tested.
The dds instrument can be used to display the activation state of the clutch button.
If none of the aforementioned tests identify the problem and the clutch button is in proper working order, replace the engine control unit.
Component replacement methods
No special measures are necessary in order to replace the clutch button.
Digital rpm indication function
This function displays the number of rpms for improved
accuracy when setting idle rpm.
To access the function it is necessary to view the "setting" menu page 48, using
button (1, fig. 14) ?"
