Defect
In the door anti-entrapment detection system (photoelectric device) of buses, insufficient consideration was given to external factors such as water droplets or ambient light affecting the photoelectric tube. The device may incorrectly detect an obstruction when none is present. This may cause the anti-entrapment function to activate and prevent the passenger door from opening or closing.
Corrective action
On all vehicles, replace the photoelectric tube and photoelectric relay with corrected/revised parts, and adjust the optical axis alignment.
