Filing in context
The Starting System is the most frequently cited component category in this archive, appearing in 35 of its 4,890 filings. This filing is one of 70 Mitsubishi notifications from 2006 in this archive. For scale, 4,831 of the 4,890 filings in this archive report a larger number of affected vehicles.
Defect
On large route buses, the flywheel ring gear hardness and the starter magnetic switch activation circuit wiring length are incorrect. During a start attempt, the starter pinion collides with the flywheel ring gear due to improper engagement, causing chipping and damage to the gear teeth. This makes engine starting difficult or impossible. If start attempts are repeated, the condition may, in the worst case, result in a vehicle fire. Note: This recall supplements notification no. 1222 (September 15, 2004), which contained errors in the affected vehicle selection; additional vehicles have been identified and are covered under this new filing.
Corrective action
On all vehicles, replace the starter assembly with the corrected part (equipped with a starter relay) and install an additional delay relay. Inspect the flywheel ring gear tooth surface; replace with a new part if any abnormality is found.

状況
大型路線バスの始動装置において、フライホイールリングギヤの硬度及びスタータマグネチックスイッチ起動回路の配線長さが不適切なため、始動操作時にスタータピニオンがフライホイールリングギヤに衝突干渉し、噛合い不良からギヤ端部が欠損、損傷することがある。そのため、エンジンの始動が困難あるいは不能となり、始動操作を繰返し行なうと、最悪の場合、火災になるおそれがある。 備考）本件は、平成１６年９月１５日付け「届出番号１２２２」にてリコール届出を行ったものですが、対象車両の選定に一部誤りがあったため、対象車両を追加し、新たに届出するものです。
改善措置
全車両、スタータ一式を対策品（スタータリレー付）と交換するとともに、遅延リレーを追加装着する。また、フライホイールリングギヤのギヤ面を点検し、異常が認められた場合は新品と交換する。
