ENGINE STOPPING DUE TO SIDESTAND OPERATION

When the engine is running and the transmission is in gear, the engine will stop if the sidestand is

moved down. This is because the electric current from the ECU does not flow to the ignition coils or fuel

injectors when the neutral switch or sidestand switch is open. However, the engine continues to run

under the following conditions:

• The transmission is in gear (the neutral switch is open) and the sidestand is up (the sidestand switch

circuit is closed).

• The transmission is in neutral (the neutral switch is closed) and the sidestand is down (the sidestand

switch circuit is open).
