Defect
In the Hybrid Powertrain Control Module (HPCM) of hybrid vehicles, the control software for the high-voltage cooling system is incorrect. When the electric water pump fails, the temperature of the drive motor and related components may rise. Continued operation may cause the thermal protection control to activate, shutting down the engine and drive motor and cutting power transmission. In the worst case, the vehicle becomes inoperable.
Corrective action
On all vehicles, the HPCM high-voltage cooling system control software is reprogrammed with a corrected program that prevents loss of mobility in the event of an electric water pump failure.

状況
ハイブリッド車のハイブリッドパワートレインコントロールモジュール（ＨＰＣＭ）において、高電圧冷却システムの制御プログラムが不適切なため、電動ウォーターポンプ故障時に駆動モータ等の温度が上昇することがある。そのため、そのままの状態で使用を続けると、最悪の場合、過熱保護制御が作動してエンジン及び駆動モータが停止し、動力が伝達されなくなり走行不能となるおそれがある。
改善措置
全車両、ＨＰＣＭの高電圧冷却システムの制御プログラムを電動ウォーターポンプ故障時に走行不能とならないよう、対策したプログラムに書き換える。
