What the ministry says is wrong

 平成28年排出ガス規制対応の大型トラックにおいて、エンジン制御システム(EMS)のプログラムが不適切なため、実走行における幾つかの運転条件下において後処理制御モジュール(ACM)のSCR監視機能がOBD閾値を適正に監視できないことがある。そのため、窒素酸化物(NOx)の排出値が基準値を超えるおそれがある。

What is to be done about it

 全車両、当該エンジン制御モジュール及び後処理制御モジュールのプログラムを対策プログラムに書き換える。

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

ボルボ elsewhere in this register

ボルボ is named on 203 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 a Volvo: 207 in the register, and 462 Japanese vehicle recall notifications filed in 2019.
