Filing in context
The Computer (Emissions/Noise) is the most frequently cited component category in this archive, appearing in 9 of its 4,890 filings. This filing is one of 41 Nissan notifications from 2012 in this archive. For scale, 1,300 of the 4,890 filings in this archive report a larger number of affected vehicles; the vehicles involved here were manufactured over a span of about 3 years and 11 months.
Defect
On diesel-powered vehicles equipped with a DPF (Diesel Particulate Filter), the engine control computer uses incorrect PM (particulate matter, including black smoke) regeneration logic. Repeated short-distance driving causes excessive PM accumulation. Despite PM levels reaching the regeneration-prohibited threshold, the flawed control logic still initiates automatic regeneration, which burns off the trapped particulates. Continued operation under these conditions causes the DPF to reach extremely high temperatures during automatic regeneration. In the worst case, the DPF may be damaged and emit black smoke.
Corrective action
On all vehicles, reprogram the engine control computer. Inspect the DPF and, if damage is found or suspected, replace it with a new part.

状況
ディーゼルエンジン搭載車のＤＰＦ（ディーゼル粒子状物質除去装置）のエンジン制御コンピュータにおいて、ＰＭ（黒煙等からなる粒子状物質）除去の制御が不適切なため、短時間の走行を繰り返した場合、ＰＭが多量に堆積するものがある。また、ＰＭが多量に堆積して再生禁止領域に達しているにも関わらず制御が不適切なため、自動再生（捕集した粒子状物質の燃焼除去）が行なわれる。そのため、そのままの状態で使用を続けると、ＰＭが多量に堆積した状態で自動再生が行なわれてＤＰＦが高温となり、最悪の場合、ＤＰＦが破損して黒煙が排出されるおそれがある。
改善措置
全車両、当該エンジン制御コンピュータのプログラムを修正するとともに、ＤＰＦを点検して損傷のおそれがある場合には、ＤＰＦを新品と交換する。
