What the notice says 原動機において、制御ユニットの燃料噴射量の制御プログラムの制御数値が誤っていたために燃料流量が過多になっていたこと及び低温時における燃焼圧抑制の制御がないことにより、燃焼圧が高くなり、原動機筒内及びクランクシャフトに過大な負荷がかかる場合がある。そのため、そのままの状態で使用を続けると、クランクシャフト固定部に亀裂が発生し、エンジンが破損するおそれがある。

What the ministry says is wrong

原動機において、制御ユニットの燃料噴射量の制御プログラムの制御数値が誤っていたために燃料流量が過多になっていたこと及び低温時における燃焼圧抑制の制御がないことにより、燃焼圧が高くなり、原動機筒内及びクランクシャフトに過大な負荷がかかる場合がある。そのため、そのままの状態で使用を続けると、クランクシャフト固定部に亀裂が発生し、エンジンが破損するおそれがある。

What is to be done about it

全車両、燃料流量適正化と低温時の燃焼圧抑制を制御する原動機制御ユニットのプログラムへ書き換える。なお、原動機制御プログラムの見直しに伴い、車両制御ユニットのプログラムも書き換える。

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

日立 elsewhere in this register

日立 is named on 95 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 Hitachi: 96 in the register, and 311 Japanese vehicle recall notifications filed in 2012.
