Issue
On large route buses equipped with EZGO/CB (a stop-assist system that activates when the center door is opened), the electrical circuit of the EZGO brake valve is incorrectly configured. When the center door is opened just before the vehicle comes to a stop, the front and rear brakes engage at a timing that differs from the designed sequence. This causes greater deceleration than intended and, in the worst case, may cause standing passengers to fall.
Corrective action
On all affected vehicles, correct the EZGO brake valve electrical circuit to the specified configuration.

状況
大型路線バスのＥＺＧＯ／ＣＢ（中扉開時の停車補助装置）付車両において、ＥＺＧＯブレーキバルブの電気回路が不適切なため、停車直前の中扉開操作時に前後ブレーキの作動タイミングが正規状態と異なっている。そのため、想定より大きな減速度が生じ、最悪の場合、立席の乗客が転倒するおそれがある。
