Register
Japan — Ministry of Land, Infrastructure, Transport and Tourism

What the ministry says is wrong

小型トラックにおいて、開発時のエンジン制御プログラムの評価が不適切なため、上流ＮＯｘセンサの故障診断が確定した際にＥＧＲ（排気ガス再循環装置）が作動を停止し、設計意図と不一致となる。そのため、保安基準第３１条の細目告示第４１条別添４８の車載式故障診断装置（ディーゼル重量車Ｊ－ＯＢＤⅡ）の技術基準を満足しない。

What is to be done about it

全車両、エンジン制御ユニットの制御プログラムを対策プログラムに修正する。また、特定の故障コードが確認された場合は、ＤＰＤ（粒子状物質除去装置）の再生を実施する。

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

いすゞ elsewhere in this register

いすゞ is named on 823 notices in the copy of MLIT’s register held here, of which these are the nearest to this one in time.

The same part: コンピュータ(エンジ

219 notices in this register name コンピュータ(エンジ. 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 an Isuzu: 834 in the register, and 371 Japanese vehicle recall notifications filed in 2024.
