不明 不明. Published by MLIT as 1212250 on 10 May 2005. Part: 圧力制御伝達部.

What the notice says ブレーキペダルの踏力を軽減する倍力装置(ブレーキハイドロブーストモジュール)に組み込まれているアキュームレーター(油圧の脈動を一時的に貯え変動を小さくするための装置)の油圧制御バルブにおいて、当該バルブ表面の加工が不良なため、アキュームレーター内の油圧が上昇した場合においても当該バルブが円滑に作動せず、油圧が適切に制御されないことがある。そのため、そのままの状態で使用を続けると、アキュームレーター内の油圧が上昇した場合にアキュームレーターが外れて油圧の制御が不能となり、最悪の場合、制動力が低下するおそれがある。また、油圧は制動装置の他にパワーステアリング装置にも供給されているため、ハンドルの操舵力が増大するおそれがある。

Is your vehicle included? Check with your VIN at MLIT, or ask a dealer. This page is an independent copy of the notice, kept so you can see what changed after it was published. It is not the authority, and the authority’s own text is the one to act on.

What the ministry says is wrong

ブレーキペダルの踏力を軽減する倍力装置(ブレーキハイドロブーストモジュール)に組み込まれているアキュームレーター(油圧の脈動を一時的に貯え変動を小さくするための装置)の油圧制御バルブにおいて、当該バルブ表面の加工が不良なため、アキュームレーター内の油圧が上昇した場合においても当該バルブが円滑に作動せず、油圧が適切に制御されないことがある。そのため、そのままの状態で使用を続けると、アキュームレーター内の油圧が上昇した場合にアキュームレーターが外れて油圧の制御が不能となり、最悪の場合、制動力が低下するおそれがある。また、油圧は制動装置の他にパワーステアリング装置にも供給されているため、ハンドルの操舵力が増大するおそれがある。

What is to be done about it

全車両、当該油圧制御バルブを点検し、該当するものはブレーキハイドロブーストモジュールを良品と交換する。

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.

Source: Ministry of Land, Infrastructure, Transport and Tourism website (出典:国土交通省ウェブサイト), used under the Public Data License 1.0. This site gathered the record, grouped it by notification number and set it in English around the ministry's own words; the notice itself is unaltered. CarsMultiverse is not the ministry and not a safety authority. To act on this notice, use the ministry's own document.

The Japanese register on this site

不明 elsewhere in this register

不明 is named on 19 notices in the copy of MLIT’s register held here, of which these are the nearest to this one in time.

The same part: 圧力制御伝達部

409 notices in this register name 圧力制御伝達部. A defect that keeps returning under one heading is worth reading as a group rather than one notice at a time.

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: 427 Japanese vehicle recall notifications filed in 2005.
