Defect
On vehicles equipped with a DPF (Diesel Particulate Filter), the engine control unit's automatic regeneration activation conditions—the combustion removal of collected particulate matter—are incorrectly programmed, causing automatic regeneration to occur excessively frequently during very low-speed or very short-distance driving. This allows excess fuel to mix into the engine oil. If the vehicle continues to be operated with the engine oil level above the specified volume, engine oil enters the intake path, producing white smoke and causing engine speed to rise uncontrollably. In the worst case, the engine may stall and fail to restart.
Corrective action
Reprogram the engine control unit software on all vehicles and replace the engine oil with fresh oil.

状況
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、自動再生（捕集した粒子状物質の燃焼除去）の作動条件が不適切なため、極低速や極短距離の走行において、自動再生が頻繁に行なわれるおそれがある。そのため、余剰な燃料がエンジンオイルに混入し、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
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。
