Defect
The current rectification module within the DC-DC converter has an improper internal component design. Due to manufacturing variation, the module may fail in service and form a short circuit. This causes a warning light to illuminate while current continues to flow from the auxiliary battery, generating heat. In the worst case, this may result in a vehicle fire.
Corrective action
Replace the DC-DC converter on all vehicles with a corrected part.

状況
電圧変換装置（ＤＣ－ＤＣコンバータ）の電流整流モジュールにおいて、内部の部品構造が不適切なため、製造ばらつき等により使用過程で当該モジュールが故障した際、短絡回路が形成されることがある。そのため、警告灯が点灯するとともに補機バッテリから電流が流れ続けて発熱し、最悪の場合、火災に至るおそれがある。
改善措置
全車両、ＤＣ－ＤＣコンバータを対策品に交換する。
