Hazard
The photoelectric sensor (photoelectric device) for bus door pinch prevention is insufficiently designed to withstand external factors such as water droplets on the phototube and stray light. This can cause false detection of obstacles when none are present, potentially causing the anti-pinch function to activate and preventing the automatic passenger door from opening and closing.

バスの扉挟み込み防止用検知器（光電装置）において、光電管への水滴付着や外乱光等の外的要因に対する検討が不十分なため、障害物がないのに障害物があると検知することがある。そのため、挟み込み防止機能が作動し乗降用自動扉が開閉できなくなるおそれがある。
Remedy
All vehicles will have the phototube and photoelectric relay replaced with revised components, and the optical axis will be adjusted.
