Defect
On gasoline vehicles equipped with a regenerative braking system, variation in the noise filter characteristics of the fuel pump controller may cause the controller to misidentify normal current noise in the fuel pump circuit as overcurrent during engine restart from an idling stop, and incorrectly flag a fault. As a result, the engine warning lamp illuminates, the fuel pump stops operating, and the engine may stall.
Corrective action
On all vehicles, reprogram the fuel pump controller software to one suited to the noise filter characteristics.

状況
減速エネルギー回生システムを搭載したガソリン車において、フューエルポンプコントローラーのノイズフィルターの特性のばらつきにより、アイドリングストップからのエンジン再始動時に、燃料ポンプに流れる電流のノイズ成分を過電流と誤検知し、故障と判定することがある。そのため、エンジン警告灯が点灯し、燃料ポンプの作動が停止してエンストするおそれがある。
改善措置
全車両、フューエルポンプコントローラーの制御プログラムをノイズフィルターの特性に適したものに書き換える。
