Defect
On vehicles converted to electric vehicle configuration, the high-voltage harness connector section of the integrated DCDC converter and on-board charger unit has inadequate waterproofing. During driving in rain or similar conditions, water may enter the connector. Continued use in this condition degrades insulation in the high-voltage circuit, causing the fail-safe function to cut power supply. This may render the vehicle inoperable or prevent charging.
Corrective action
Apply sealant to the high-voltage harness connector sections (two locations) on all vehicles.

状況
電気自動車に改造した車両において、ＤＣＤＣコンバータ及び車載充電器一体ユニットの高圧ハーネスのコネクタ部の防水性が不適切なため、雨天走行時等にコネクタ内部に水が浸入することがある。そのため、そのままの状態で使用を続けると、高圧部の絶縁性が低下するため、フェイル機能により電源供給を遮断して走行不能になる、あるいは充電できなくなるおそれがある。
改善措置
全車両、高圧ハーネスのコネクタ部へシール剤を塗布する。（２箇所）
