Overview
| MLIT filing number | 1141250 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | October 5, 2017 |
| Manufacturer(s) | Isuzu |
| Component | Engine Control Computer |
| Production period | July 18, 2017 — August 30, 2017 |
| Vehicles affected | 23 units |
Defect
On large buses, the engine control unit software is incorrectly programmed, causing carbon monoxide emissions during acceleration to exceed the Safety Standards limit. Black smoke output may also increase, leading to particulate matter (PM) clogging the diesel particulate removal device (DPR) and illuminating the engine warning light. In the worst case, the DPR may be damaged.
Corrective action
On all vehicles, reprogram the engine control unit software and inspect the DPR. If the DPR is found to be damaged, replace it with a new unit.

状況
大型バスにおいて、エンジン制御コンピュータのプログラムが不適切なため、加速時に一酸化炭素の排出量が保安基準の基準値を超える。さらに、黒煙排出量が増加することがあり、そのため、ＤＰＲ（ディーゼル微粒子除去装置）にＰＭ（粒子状物質）が詰まりエンジン警告灯が点灯し、ＤＰＲが損傷するおそれがある。
改善措置
全車両、エンジン制御コンピュータのプログラムを書き換えるとともに、ＤＰＲ（ディーゼル微粒子除去装置）を点検し、損傷している場合は新品に交換する。
