Issue
On minibuses, the automatic transmission fail-safe control program is improperly designed. When the vehicle speed sensor malfunctions, the fail-safe function does not activate, allowing the transmission to abruptly downshift to a low gear while the vehicle is in motion. In the worst case, this causes sudden deceleration while driving.
Corrective action
On all vehicles, replace the automatic transmission ECU with a corrected part.
