Defect
In the diesel engine, over-speed control is incorrect. During full-throttle operation and similar conditions, oil contained in blow-by gas within the intake path may combust inside the combustion chamber, causing engine speed to rise uncontrollably. This leads to insufficient engine lubrication and seizure, and in the worst case, engine damage.
Corrective action
On all vehicles, reprogram the control software with the corrected software.

状況
⑤ディーゼルエンジンにおいて、過回転制御が不適切なため、アクセル全開等の際、吸気経路内のブローバイガスに含まれるオイルが燃焼室内で燃焼し、エンジン回転が上昇することがある。そのため、エンジンの潤滑が不足して焼き付き、最悪の場合、エンジンが破損するおそれがある。
改善措置
全車両、制御プログラムを対策プログラムに修正する。
