Novabus vehicle multiplex software may unexpectedly cause the door system electronic control module (ECM) to open and close the rear passenger door when the bus stops.
The short version
Nova Bus (US) Inc. reported a problem with the electrical system software. Here is what owners need to know.
The vehicle multiplex software may unexpectedly cause the door system electronic control module (ECM) to open and close the rear passenger door when the bus stops.
A passenger may exit the bus in an unsafe location if the rear passenger door opens unexpectedly, increasing the risk of injury. Additionally, the doors may unexpectedly close on an exiting passenger, increasing the risk of injury.
Nova Bus will provide instructions for how to update the vehicle multiplex and door system ECM software, and install a hardware dedicated wire kit, free of charge.
