Defect
On large buses, the engine control unit software is incorrect, causing carbon monoxide emissions during acceleration to exceed the limit specified in the Safety Standards. Black smoke output also increases, causing particulate matter (PM) to accumulate in the DPR (Diesel Particulate Removal) device. This triggers the engine warning light and may damage the DPR.
Corrective action
Reprogram the engine control unit on all vehicles. Inspect the DPR (Diesel Particulate Removal) device and replace it with a new unit if damage is found.

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。
