Filing in context
The Wiring is the most frequently cited component category in this archive, appearing in 236 of its 4,890 filings. This filing is one of 24 Toyota notifications from 2005 in this archive. For scale, 2,009 of the 4,890 filings in this archive report a larger number of affected vehicles; the vehicles involved here were manufactured over a span of about 7 months.
Defect
The wiring terminal of the DC-DC converter, which charges the auxiliary battery, is improperly designed. Extended use under high electrical load conditions — such as cold weather operation — allows oxides to form at the crimped terminal connection, generating heat and causing a disconnection. This prevents the auxiliary battery from charging. In the worst case, the engine and electric motor may shut down while driving and cannot be restarted.
Corrective action
On all vehicles, verify the serial number of the DC-DC converter. On affected units, replace the wiring with the corrected part.

状況
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。
改善措置
全車両、電圧変換装置の製造番号を確認し、該当するものは当該電気配線を対策品に交換する。
