Overview
| MLIT filing number | 1114891 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | July 21, 2005 |
| Manufacturer(s) | Mazda |
| Component | Engine Control Computer |
| Production period | February 14, 2003 — June 30, 2005 |
| Vehicles affected | 31,431 units |
Defect
The engine control unit software is incorrectly programmed, causing the engine to remain at high RPM without returning to idle. If the vehicle is stopped without switching off the engine, the engine may continue running at high RPM. This abnormally elevates the temperature beneath the vehicle floor, which can melt the resin fuel tank, electrical wiring, and parking brake cable sheathing. In the worst case, this leads to a fuel leak, engine stall, or parking brake malfunction.
Corrective action
On all vehicles, inspect the resin fuel tank and related components; replace any damaged parts with new ones. On vehicles not equipped with a heat shield pad, install the pad. Additionally, reprogram the engine control unit software or replace the unit with a corrected part.

状況
①エンジン制御用コンピュータのプログラムが不適切なため、エンジンが高回転から下がらず、車両を停止させてもエンジンを切らない場合には、そのまま高回転で維持される場合がある。そのため、車体床面下部の温度が異常に上昇して樹脂製燃料タンク、電気配線、駐車ブレーキケーブルの被覆等が溶損し、最悪の場合、燃料漏れ、エンスト、駐車ブレーキの作動不良等に至るおそれがある。
改善措置
①全車両、樹脂製燃料タンク等を点検して、異常が認められるものは新品と交換すると共に、熱害防止パッドが装着されていない車両は当該パッドを装着する。また、エンジン制御用コンピュータのプログラムを書き換える又は当該コンピュータを対策品と交換する。
