Defect
On welfare vehicles equipped with a hydraulic wheelchair lift, the floor-level detection switch has insufficient dust resistance, allowing sand and other foreign matter to accumulate around the switch. In addition, the return hose that routes oil seeping from the hydraulic cylinder back to the reservoir tank is damaged by repeated bending during lift operation, and may drip oil onto the switch. The dripping oil promotes the ingestion of sand and foreign matter around the switch, causing the switch to malfunction. As a result, the automatic stop function that halts the lift when it reaches floor level fails to activate, the lift transitions to the stow cycle, the platform tilts, and the wheelchair may fall over inside the vehicle cabin.
Corrective action
On all vehicles, replace the floor-level detection switch with a corrected part and install a dust-protection cover over the switch mounting area. Additionally, reposition the return hose and replace it with a corrected part made of a revised material.

状況
車椅子用油圧式リフトを架装した福祉車両において、車両床面位置検知用スイッチの防塵性が不十分なため、砂塵等の異物がスイッチ周辺部へ付着することがある。また、油圧シリンダから微量に染み出したオイルをリザーバータンクに戻すリターンホースが、リフト使用時の屈曲の繰り返しにより損傷し、当該スイッチ部にオイルが垂れるおそれがあり、垂れたオイルが助長要因となり当該スイッチ周辺部に砂塵等の異物が噛込み、作動不良となる場合がある。そのため、リフトが床面まで上昇すると自動停止する機能が機能せず、収納動作に移行し、リフトが傾き、車室内へ車椅子が転倒するおそれがある。
改善措置
全車両、床面位置検知用スイッチを対策品と交換し、スイッチ設置部へ防塵用カバーを装着する。また、リターンホースの取付け位置を変更し、リターンホースを材質変更した対策品と交換する。
