Defect
In the center door open/close mechanism of single-operator buses, the door control logic is incorrectly specified. When a particular sequence of operations is performed while the door is open, the system may fail to correctly detect the door's open/closed state. As a result, the function that prevents the bus from moving while the door is open may not activate, and the vehicle may depart with the door open.
Corrective action
On all vehicles, replace the door ECU with a corrected part. Because parts require time to procure, owners will be notified of the defect and provided with interim operating precautions.
