Affected vehicles

Toyota Estima Hybrid 2001

Hazard

The terminal connectors of the electrical wiring for the DC-DC converter that charges the auxiliary battery are improperly crimped. Under prolonged use with increased electrical load, such as in cold weather, oxidation may form at the crimped joint, causing heat generation and wire breakage. This can prevent charging of the auxiliary battery, and in the worst case, cause the engine or motor to shut down during driving with inability to restart.

補機バッテリーを充電する電圧変換装置(DC-DCコンバータ)の電気配線の端子が不適切なため、寒冷時等、電気負荷が増加するような使用を長期間行うと、当該かしめ部に酸化物が生成され、発熱し断線するものがある。そのため、補機バッテリーへの充電ができなくなり、最悪の場合、走行中に原動機や電動機(モーター)が停止し、再始動できなくなるおそれがある。

Remedy

For all vehicles, verify the manufacturing number of the DC-DC converter. For affected units, replace the electrical wiring with the corrective parts.
