What the ministry says is wrong

 大型路線バスのエンジンインテークエアヒータリレーにおいて、リレー内部電気接点の耐久性が不足しているため、アイドリングストップ機能や、停留所等でのエンジン停止始動を頻繁に繰り返すと、接点部がアーク放電により溶損することがある。そのため、そのままの状態で使用を続けると、接点が溶着状態となり発熱して炭化・発煙し、最悪の場合、リレー及び配線の一部が焼損に至るおそれがある。

What is to be done about it

 全車両、インテークエアヒータリレーを新品に交換する。また、エアヒータ機能を解除する手動ON/OFFスイッチを追加し適切な使用を励行するステッカーを貼付し、エアヒータの作動条件等を明記したリーフレットを配布する。  なお、追加部品の供給に時間を要することから、当該リレーを先行して交換し、追加部品は供給の準備でき次第、改めて取付けする。

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

ニッサンディーゼル elsewhere in this register

ニッサンディーゼル is named on 239 notices in the copy of MLIT’s register held here, of which these are the nearest to this one in time.

The same part: 装置その他

210 notices in this register name 装置その他. 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 Nissan Diesel: 241 in the register, and 421 Japanese vehicle recall notifications filed in 2020.
