ニチユ三菱 Wdr-F20D. Published by MLIT as 1140550 on 6 June 2017. Part: その他(制御装置).

What the notice says 制動倍力装置　のバキュームポンプ　の作動を制御する負圧スイッチにおいて，製造時にスイッチ内のシリコンゴムの二次加硫をしていないものがあり，スイッチ内にシロキサン等のガスが発生し，可動接点が固定接点から離れる際のアーク放電により，接点部に絶縁性の高いシリコン化合物が生成されることがある。そのため，接点の抵抗が増え導通不良となり，負圧タンク内の負圧が低下しても，負圧スイッチが作動しないためバキュームポンプが作動せず，ブレーキペダルの操作力が増大し，制動距離が長くなるおそれがある。また，負圧タンク内の負圧が低下した際，警告ブザー　が鳴るが，音量が小さいため，運転者が負圧低下に気付かないおそれがある。

What the ministry says is wrong

制動倍力装置　のバキュームポンプ　の作動を制御する負圧スイッチにおいて，製造時にスイッチ内のシリコンゴムの二次加硫をしていないものがあり，スイッチ内にシロキサン等のガスが発生し，可動接点が固定接点から離れる際のアーク放電により，接点部に絶縁性の高いシリコン化合物が生成されることがある。そのため，接点の抵抗が増え導通不良となり，負圧タンク内の負圧が低下しても，負圧スイッチが作動しないためバキュームポンプが作動せず，ブレーキペダルの操作力が増大し，制動距離が長くなるおそれがある。また，負圧タンク内の負圧が低下した際，警告ブザー　が鳴るが，音量が小さいため，運転者が負圧低下に気付かないおそれがある。

What is to be done about it

二次加硫していないシリコンゴムを使用している負圧スイッチを良品に交換する。また，全車両，警告ブザーを対策品に交換する。

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.

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.

The Japanese register on this site

ニチユ三菱 elsewhere in this register

ニチユ三菱 is named on 11 notices in the copy of MLIT’s register held here, of which these are the nearest to this one in time.

The same part: その他(制御装置)

146 notices in this register name その他(制御装置). 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: Japanese recalls on a Nichiyu Mitsubishi: 11 in the register, and 425 Japanese vehicle recall notifications filed in 2017.
