IGNITION SYSTEM

7-3

ET1D71043

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 ignition coils does not flow to the ECU when 
both the neutral switch and sidestand switch are set to “OFF”, thereby preventing the spark plugs from 
producing a spark. However, the engine continues to run under the following conditions:
• The transmission is in gear (the neutral switch circuit is open) and the sidestand is up (the sidestand 

switch circuit is closed).

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

estand switch circuit is open).
