Defect

The DC-DC converter contains an internal electronic circuit board on which some capacitors have developed cracks. These cracked capacitors may short circuit, causing the DC-DC converter to melt. In the worst case, a vehicle fire may occur.

Corrective action

On all vehicles, replace the DC-DC converter with a corrected part and add a protective cover to the harness to prevent damage during replacement. Because an initial shortage of corrected parts is anticipated, some vehicles will receive an interim measure: a bypass is added to prevent current from flowing through the DC-DC converter, and the engine control program is reprogrammed. Once corrected parts become available, those vehicles will have the DC-DC converter replaced with the corrected part, the harness protective cover installed, and the engine control program reprogrammed.

状況

DC-DCコンバータにおいて、内部の電子基板上のコンデンサに亀裂が入っているものがあり、当該コンデンサがショートする可能性がある。そのため、DC-DCコンバータが溶損し、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。加えて交換時にハーネスを傷付けないよう、ハーネスにプロテクターを追加する。なお、当初、対策品の不足が見込まれるため、車両によっては暫定でDC-DCコンバータに電流が流れないようにショートカットを追加するとともに、エンジン制御プログラムを書き換える。当該車両においては、対策品の準備が出来次第、DC-DCコンバータを対策品と交換、ハーネスにプロテクターを追加するとともに、エンジン制御プログラムを書き換える。
