Affected vehicles

Lexus GS350 2002–2006 Toyota Crown 2002–2006

Hazard

The fuel pump wiring inside the fuel tank is made of material that resists flexing. When the filler cap is opened, pressure changes inside the tank can cause large displacement of the pump mounting surface, resulting in the connection terminal sliding. Continued use causes terminal wear and heat generation from electrical current, reducing terminal mating force and causing poor electrical contact. This leads to fuel pump stoppage, resulting in inability to start the engine or stalling while driving.

燃料タンク内の燃料ポンプ用電線が屈曲しにくい材質のため、給油口を開けた際のタンク内圧変化でポンプ取付面が大きく変位した場合に接続端子部が摺動することがある。そのため、そのまま使用を続けると、接続端子部が摩耗し、通電により発熱することで端子嵌合力が低下し導通不良となり、燃料ポンプが停止し、エンジン始動不能や走行中にエンストするおそれがある。

Remedy

All vehicles: Replace the affected wiring with corrective parts.
