Defect

In the engine control computer of gasoline-engine vehicles, an improper manufacturing process used for the electrolytic capacitors in the injector drive power circuit causes internal damage to some units. Continued use allows the damage to progress, causing the engine to stall and preventing restart. If the ignition switch is then left in the ON position, the drive components inside the injectors and high-pressure fuel pump may overheat, melting surrounding resin components and allowing fuel to leak. In the worst case, this may result in a vehicle fire.

Corrective action

On all vehicles, inspect the engine control computer and replace it with a conforming part. If the inspection reveals an abnormality, also replace the injectors and high-pressure fuel pump with new parts. Additionally, inspect the wiring harness condition and replace it with a new part if damage is found.

状況

ガソリンエンジン車のエンジン制御コンピュータにおいて、インジェクタ駆動電源回路に使用する電解コンデンサの製造工程が不適切なため、内部が損傷しているものがある。そのため、そのまま使用を続けると損傷が進み、エンジンが停止し、再始動できなくなるおそれがある。さらに、エンジンスイッチをオンの状態で維持していると、インジェクタや高圧燃料ポンプ内部の駆動部が過熱し、樹脂部が溶けて燃料が漏れ出し、最悪の場合、火災に至るおそれがある。

改善措置

全車両、エンジン制御コンピュータの状態を点検し良品と交換する。点検の結果、異常がある場合は、インジェクタ、高圧燃料ポンプを新品と交換する。あわせて、ハーネスの状態を確認し、損傷がある場合はハーネスを新品と交換する。
