Overview
| MLIT filing number | 1112880 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | October 28, 2004 |
| Manufacturer(s) | Mazda, Mitsubishi, Nissan |
| Component | Exhaust emission reduction device |
| Production period | December 2003 — March 2004 |
| Vehicles affected | 2,936 units |
Defect
The control software managing the DPF (Diesel Particulate Filter) automatic regeneration function is improperly programmed, preventing adequate removal of accumulated PM (particulate matter) from the DPF. As a result, the automatic regeneration cycle may activate while PM has accumulated to an excessive level. This causes abnormal temperature rise within the DPF, damaging the exhaust temperature sensor and illuminating the engine warning light. In the worst case, the DPF may be damaged and PM emissions may exceed the specified regulatory limit. (Note: This notification supersedes recall notification No. 1051 dated March 18, 2004, in which the corrective measures were determined to be insufficient. The remedy has been reviewed and revised accordingly.)
Corrective action
On all vehicles, inspect the DPF and exhaust temperature sensor and replace any damaged components with new parts. Replace the control unit with a corrected part. Because this remedy may cause fuel to dilute engine oil depending on operating conditions, replace the oil level gauge with a corrected part capable of detecting oil dilution. Affix a caution label to the sun visor describing the engine oil level inspection procedure, and replace the engine oil, adjusting the quantity to the specified level. Additionally, replace the existing DPF warning lamp caution label with a corrected label describing the required response when the DPF lamp flashes, and replace the owner's manual with a revised version that includes this response procedure and updated periodic inspection instructions.

状況
ＤＰＦ（ディーゼル微粒子除去装置）において、ＤＰＦ内に捕集されたＰＭ（粒子状物質 ）の自動除去機能を制御するコンピュータのプログラムが不適切なため、ＤＰＦ内のＰＭ の除去が適切にされず、ＰＭが過大に堆積した状態で自動除去機能が作動することがある 。そのため、ＤＰＦの温度が異常に上昇し、排気温度センサーが損傷してエンジン警告灯 が点灯し、最悪の場合、ＤＰＦが損傷してＰＭの排出量が基準値を超えるおそれがある。 （備考） 本届出は、平成１６年３月１８日付け「届出番号１０５１」のリコール届出において、不 具合に対する改善措置の内容が不十分であったため、改善措置の内容を見直し、再度対策 を行うものである。
改善措置
全車両、ＤＰＦ及び排気温度センサーを点検し、損傷しているものは新品と交換して、コ ンピュータを対策品と交換する。また、本対策を行うと、使用状況によっては燃料により エンジンオイルが希釈されるおそれがあるため、エンジンオイルの希釈を点検可能な対策 品のオイルレベルゲージに交換するとともに、エンジンオイル量の点検方法を記載したコ ーションラベルをサンバイザーに貼付し、エンジンオイルを交換して正規の油量に調節す る。さらにＤＰＦランプ点滅時等の措置方法を記載したコーションラベルを対策品と貼り 替え、同措置方法及び定期点検について追記した取扱説明書と差し替える。
