Filing in context
This filing is one of 19 Honda notifications from 2010 in this archive. For scale, 3,096 of the 4,890 filings in this archive report a larger number of affected vehicles; the vehicles involved here were manufactured over a span of about 1 year and 5 months.
Issue
The electrical circuit that displays starter switch operation on training vehicles is incorrectly designed. When the rider-operation indicator lamp is switched from the engine-stopped state to the starter switch operation state, the side stand safety interlock — which stops the engine if the rider attempts to ride with the side stand extended — is disabled. As a result, the motorcycle can be ridden with the side stand extended, and in the worst case, the side stand may contact the ground and cause the vehicle to fall.
Corrective action
On all vehicles, add a diode-equipped electrical wiring harness to the starter switch operation display circuit.

状況
教習用車両のスタータスイッチ操作を表示する電気回路が不適切なため、運転操作確認用ランプ表示をエンジン停止状態からスタータスイッチ操作状態に切替えた場合、サイドスタンドの格納忘れを防止する機構（サイドスタンドを出した状態で走行しようとするとエンジンが停止する機構）が作動しなくなる。そのため、サイドスタンドを出した状態で走行可能となり、最悪の場合、サイドスタンドが接地して転倒するおそれがある。
改善措置
全車両、スタータスイッチ操作を表示する電気回路に、ダイオード付電気配線を追加する。
