Overview
| MLIT filing number | 1151190 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | March 25, 2022 |
| Manufacturer(s) | Hino |
| Component | Exhaust emission reduction device |
| Production period | April 2017 — March 2022 |
| Vehicles affected | 46,746 units |
Defect
On medium-duty trucks equipped with the A05C (HC-SCR) engine, the regeneration control software for the HC-SCR catalyst is incorrect. Sulfur compounds in the exhaust gas are not removed from the catalyst and accumulate over time. This reduces catalyst performance, and nitrogen oxide emissions in the exhaust gas may exceed the regulatory limit.
Corrective action
On all vehicles, as an interim measure, inspect the SCR catalyst and perform a regeneration cycle if regeneration is possible. If regeneration cannot be performed or does not complete, replace the catalyst. Add the SCR catalyst regeneration procedure to the inspection and maintenance items in the maintenance log. Owners will be notified to bring vehicles in for repair as soon as the interim measure is ready. A permanent corrective measure will be implemented once determined.

状況
中型トラックのＡ０５Ｃ（ＨＣ－ＳＣＲ）エンジン搭載車において、ＨＣ－ＳＣＲ触媒の再生用制御プログラムが不適切なため、触媒に付着した排出ガス中の硫黄成分が除去されず堆積することがある。そのため、触媒の性能が低下し、排出ガス中の窒素酸化物の排出値が基準値を超えるおそれがある。
改善措置
全車両、暫定措置として、点検を行いＳＣＲ触媒の再生が可能な場合は再生作業を行う。再生が不可能な場合および再生完了しない場合は、触媒を交換する。また、メンテナンスノートの点検整備項目にＳＣＲ触媒再生作業を追加する。暫定措置は準備でき次第、使用者に修理入庫を通知する。また、恒久対策が決定し次第、改めて措置を実施する。
