What the notice says 電圧変換器において、制御プログラムが不適切なため、故障診断機（スキャンツール） を接続中に一時的な通信障害がサーバと、故障診断機の間に発生すると、電源変圧器に故障が発生していると判断して１次電源と２次電源の回路を遮断し、２次電源に電源が供給されなくなる。このため、２次電源のバッテリが充電されず、バッテリ上がりに至ることでｅｓｐとａｂｓの警告灯が点灯して機能が停止し、制動性能が損なわれる。このまま運転を続けると、最悪の場合、出力を低下させたフェイルセーフモードになるおそれがある。

What the ministry says is wrong
電圧変換器において、制御プログラムが不適切なため、故障診断機（スキャンツール） を接続中に一時的な通信障害がサーバと、故障診断機の間に発生すると、電源変圧器に故障が発生していると判断して１次電源と２次電源の回路を遮断し、２次電源に電源が供給されなくなる。このため、２次電源のバッテリが充電されず、バッテリ上がりに至ることでＥＳＰとＡＢＳの警告灯が点灯して機能が停止し、制動性能が損なわれる。このまま運転を続けると、最悪の場合、出力を低下させたフェイルセーフモードになるおそれがある。What is to be done about it
全車両、電圧変換器の制御プログラムを対策プログラムに書き換える。The two passages above are quoted in Japanese because that is the language the ministry published them in. This site keeps the wording a register had when it was read, and does not translate a safety notice.

Reading this against the source
This page is what MLIT published in the recall notices it publishes, kept as it was read. The authority publishes only its current wording; if a notice is rewritten, the earlier version disappears there and is kept here. The whole register is at /japan, and how the reading is done is set out in the method.
This register keeps an index of its own for every maker and every year it holds: Japanese recalls on a Mercedes-Benz: 450 in the register, and 398 Japanese vehicle recall notifications filed in 2023.
