What the ministry says is wrong

大型トラックの後2軸エアサスペンション仕様において、車高調整装置の最大車高設定値が不適切なため、荷役作業時等で最大車高まで上昇させた場合に、後後軸のショックアブソーバーが最大可動範囲を超え、その後車高を下降した際に内部部品が変形してスムーズに下降しなくなることがある。そのため、そのままの状態で使用を続けると、当該ショックアブソーバーのピストンロッドが折損して、エアスプリングと干渉しエア漏れを起こす、もしくはタイヤと干渉してバーストし、最悪の場合、発熱により発火するおそれがある。

What is to be done about it

全車両、車高調整装置のプログラムを変更するとともに、ショックアブソーバーを点検し、損傷がある場合は新品に交換する。

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

UDトラックス elsewhere in this register

UDトラックス is named on 230 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(緩衝装

3 notices in this register name コンピュータ(緩衝装. 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 UD Trucks: 231 in the register, and 425 Japanese vehicle recall notifications filed in 2017.
