Overview
| MLIT filing number | 1125801 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | July 22, 2010 |
| Manufacturer(s) | Isuzu, Nissan |
| Component | Engine control computer |
| Production period | January 26, 1999 — October 2009 |
| Vehicles affected | 920 units |
Defect
On vehicles equipped with a DPF (Diesel Particulate Filter), the engine control computer uses an incorrect fuel injection quantity setting during automatic regeneration (combustion removal of collected particulate matter) at low engine loads, allowing excess fuel to mix into the engine oil. If the vehicle continues to be operated with engine oil quantity above the specified level, engine oil enters the intake path, generating white smoke and causing engine speed to rise. In the worst case, the engine may stall and fail to restart.
Corrective action
On all vehicles, reprogram the engine control computer and replace the engine oil with new oil. On vehicles that have already experienced this condition, replace the engine assembly, injectors, and catalyst with new parts as necessary.

状況
（１）ＤＰＦ（ディーゼル粒子状物質除去装置）付き車の原動機制御コンピュータにおいて、低負荷走行時の自動再生（捕集した粒子状物質の燃焼除去）の燃料噴射量の設定が不適切なため、余剰な燃料がエンジンオイルに混入するものがある。そのため、エンジンオイル量が規定量を超えた状態で使用を続けると、吸気経路にエンジンオイルが混入して白煙が発生し、エンジンの回転が上昇することがあり、最悪の場合、エンストして再始動できなくなるおそれがある。
改善措置
（１）全車両、当該制御コンピュータのプログラムを修正するとともに、エンジンオイルを新品に交換する。なお、当該不具合が発生したことのある車両については、必要に応じて、エンジン本体、インジェクタ、触媒を新品に交換する。
