Sheesh, Charles (B)

There should always be a steering controller and a visual display
present on the CAN bus.

These are AKA the Bus Driver and the speedo, respectively.

If the Bus Driver is not present, then a warning message should display
with "Smoko Alert!"

That's the ticket. ;-)

Response: The system must display a DTC error message.

As was just pointed out to me, it's pretty hard to display an error message if you don't have a terminal........yeah go ahead and laugh!
