In the event of fault
In the event of a start button fault, the engine cannot be started.
Fault codes generated and possible correlated faults
The engine control unit generates no fault code in the event of an engine start button fault.
No errors are indicated on the dashboard
Possible correlated faults: the starter motor cannot be operated. Check:
- Battery charge.
- Integrity of the electric circuit (open circuit, short circuit to ground and toward vdc) and electrical connections of the start button.
- Integrity of the start button. In the button's two different positions, the resistance at its contacts (pin 1 and pin 2) must be zero (depressed - continuity) or infinite (released - open circuit).
- The integrity of the engine starter motor relay and its circuit.
- Integrity of the starter motor and that the motor is correctly connected to the electrical system (also check ground connection on engine, see sect. 6 - 3"Starter motor").
- The integrity of the side stand switch, the clutch lever switch, the gear position sensor and their respective circuits
- Integrity of stop engine switch.
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 engine start button.
If none of the tests described above identifies the problem and the power supply and ground for the engine control unit are in correct working order, replace the engine control unit.
Component replacement methods
No special measures are necessary in order to replace the starter button.
Checking the right-hand handlebar switch
To remove the right-hand handlebar switch, undo the retaining screws (1) and disconnect the wiring connector from the electric system.
Refitting is the reverse of removal; tighten the screws (1) to a torque of 1.3 Nm +/- 10% (sect. 3 - 3, Frame torque settings).
