Defect
In the hybrid system, the fault-detection control program is improperly configured. If a boost circuit element is damaged during high-load driving such as hard acceleration, the system may fail to transition to fail-safe control mode as intended. Consequently, a warning light illuminates, the hybrid system shuts down, and the vehicle may become inoperable.
Corrective action
On all vehicles, reprogram the fault-detection control program to the corrected specification. If an element is subsequently damaged after reprogramming and a warning light illuminates, the power converter module will be replaced free of charge.

状況
ハイブリッドシステムにおいて、異常判定時の制御プログラムが不適切なため、急加速時等の高負荷走行中に昇圧回路の素子が損傷した場合に、フェールセーフモードに移行すべきところ、移行できないことがある。そのため、警告灯が点灯し、ハイブリッドシステムが停止して、走行不能となるおそれがある。
改善措置
全車両、異常判定時の制御プログラムを対策仕様に修正する。当該制御プログラム修正後に素子が損傷して警告灯が点灯した場合は、電力変換器のモジュールを無償交換する。
