Defect
In the capacitor-based idling stop system, the overcurrent protection for the internal elements of the step-up/step-down charge-discharge converter — which controls the capacitor charge and discharge voltage — is insufficient. During restart from an idling stop, overcurrent may flow into the converter and damage its internal elements. Continued use causes the damaged elements to generate heat, carbonizing surrounding resin material and sustaining current flow, leading to smoke and heat generation. In the worst case, a vehicle fire may occur.
Corrective action
On all vehicles, replace the step-up/step-down charge-discharge converter with a corrected part.

状況
キャパシタ電源を使用しているアイドリングストップシステムにおいて、キャパシタの充放電電圧を制御する昇降圧充放電コンバータ内部素子の過電流保護が不十分なため、アイドリングストップからの再始動時等に生じた過電流が当該コンバータへ流れ、内部素子が損傷することがある。そのため、そのままの状態で使用を続けると素子が発熱し、素子周辺の樹脂材が炭化し電流が流れ続け、発煙・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、昇降圧充放電コンバータを対策品と交換する。
