Introduction
The side stand button is located on the side stand. Together with the signal from the clutch button and the neutral signal generated by the gear sensor (transmitted to the engine control unit over the can line), the side stand 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: 
Component assembling position

The side stand button is integrated in the rotation pivot area of the side stand itself.

In the event of fault
In the event of a side stand button fault, the safety 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 side stand button fault.
No errors are indicated on the dashboard.
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 side stand button.
If none of the aforementioned tests identify the problem and the side stand button is in proper working order, replace the engine control unit.
Component replacement methods
No special measures are necessary in order to replace the side stand button.

Note
This operation is described for an engine removed from the frame since all
reassembly procedures are easier with the
engine on the bench.

Adjusting the steering head bearings
Note
To adjust the steering bearing clearance, follow what is described in
sect. 4 - 3, Adjusting the steering head bearings.
If the problems found are not solved, check the wear of steering bearings (6)
and replace them, if necessary, as described
in paragraph "removal of the steering head c ...
Operating principle of dtc
The bbs receives the front and rear speed information from the abs over the
can. Then, the bbs sends the vehicle speed
information to be displayed on the dashboard over the can.
If the tangential speed of the rear wheel exceeds the tangential speed of the
front wheel by a given percentage, t ...
