Overview
| MLIT filing number | 1138660 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | July 29, 2016 |
| Manufacturer(s) | UD Trucks |
| Production period | September 13, 2013 — July 19, 2016 |
| Vehicles affected | 12,565 units |
Defect
On vehicles equipped with the forward obstacle collision mitigation system (Traffic Eye Brake System), a functional limitation in the millimeter-wave radar obstacle detection software may cause the system to rarely misidentify radar returns from an overpass and a road expansion joint located at the same position as a forward obstacle, when no preceding vehicle is present. When this occurs, a warning is displayed on the monitor and an audible alert sounds, and unexpected emergency braking may be applied.
Corrective action
On all vehicles, replace the millimeter-wave radar unit with an improved unit incorporating updated obstacle detection software. Owner's manuals will have a corrected information leaflet affixed. Because full availability of the improved units requires additional time, replacement will begin with vehicles that travel the affected road sections most frequently.

状況
前方障害物衝突軽減制御装置（トラフィックアイブレーキシステム）装着車において、ミリ波レーダによる障害物検知プログラムの機能限界により、先行車がいない状況下で高架橋と道路継ぎ目が同位置にある場所を走行した際に、ミリ波情報を稀に前方障害物と誤認識することがある。そのため、表示モニタに警告表示がされるとともに警告音を発し、使用者の予期せぬ急制動がかかるおそれがある。
改善措置
全車両、ミリ波レーダの障害物検知プログラムを変更した改良品と交換する。また、取扱説明書は、当該情報の記載内容を訂正したリーフレットを貼り付ける。 なお、改良品の全数準備に時間を要することから、当該特定区間の走行頻度が多い車両から順々に交換を開始する。
