Defect
On large tractors, the coupler lock guard designed to prevent improper trailer coupling has an incorrect geometry. When a coupling operation is performed with the tractor and trailer at mismatched heights, the lock guard may fail to function correctly, resulting in an improper coupling state. Simultaneously, the coupler lock indicator lamp inside the instrument cluster may illuminate, falsely indicating a completed coupling. If the operator does not visually verify the coupling state and continues operation, the trailer may separate from the tractor while in motion.
Corrective action
Notify all operators to align the tractor and trailer heights before coupling and to visually verify the coupling state after each operation. On all vehicles, replace the lock guard with the corrected part.

状況
大型トラクタの連結装置において、誤連結を防止するロックガードの形状が不適切なため、トラクタとトレーラの高さがあっていない状態で連結操作をおこなうと、ロックガードが正しく作動せず誤連結状態となるとともに、メータ内に連結完了を示すカプラロックのランプが点灯することがある。そのため、目視による連結状態の確認をしないまま使用を続けると、走行中にトレーラが分離するおそれがある。
改善措置
使用者に連結操作時にトラクタとトレーラの高さを合わせること、および完了後に連結状態を目視確認することを周知するとともに、全車両、ロックガードを対策品に交換する。
