Defect
In the regenerative braking energy recovery system, the capacitor fault detection program in the engine control computer is incorrect. As a result, a normally functioning capacitor may be incorrectly identified as faulty, causing the alternator to stop generating power. This triggers the charge warning light and displays a "Charging System Error" message on the display. If driving continues, decreasing battery voltage causes the engine warning light to illuminate and acceleration performance to degrade progressively. In the worst case, the engine stalls and cannot be restarted.
Corrective action
On all vehicles, reprogram the capacitor fault detection program in the engine control computer with the corrected software.

状況
減速エネルギー回生システムにおいて、キャパシタの故障判定プログラムが不適切なため、キャパシタが正常であるにもかかわらず、故障と判定し、オルタネータの発電を停止して、充電警告灯が点灯するとともにディスプレイに「充電システム異常」と表示されることがある。そのまま走行を続けると、バッテリ電圧の低下により、段階的にエンジン警告灯の点灯や加速不良となり、最悪の場合、エンジンが停止して再始動できなくなるおそれがある。
改善措置
全車両、エンジン制御コンピュータのキャパシタ故障判定プログラムを書き換える。
