What the ministry says is wrong
ショベル・ローダの駐車ブレーキにおいて、駐車ブレーキバルブへの雨水等の浸入に対する検討が不十分なため、コネクタリード線挿入部の隙間から雨水等が浸入することがある。そのためそのまま使用を続けると、ソレノイド内部に錆が発生して駐車ブレーキを解放状態に保持する力が減少し、最悪の場合、走行中に駐車ブレーキが作動するおそれがある。What is to be done about it
全車両、 １．ソレノイドを新品に交換する。 ２．コネクタにシリコン接着シール剤を塗布する。 ３．一部の配線の取り回しを変更する。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 Komatsu: 297 in the register, and 398 Japanese vehicle recall notifications filed in 2023.
