When you see the dbg> prompt on the screen, the software is successfully started and
you can start entering commands. If any of the self-tests fails, the diagnostic
commands are not available.
If the status of any of the self-tests is FAILED, the system resets the software and runs
the self-tests again. If the status still remains FAILED, there is a physical error in the
module. In such a case, you cannot test that specific module with the diagnostic
commands.
5.4.3 Note on commands
Some commands in the diagnostics software are informative. They display information
about, for example, the module status.
However, with some commands you can actually change the module operation and,
thus, the operation of the entire bus. These commands are mainly intended for
troubleshooting in laboratory conditions, not on board the train with an active system
running. The system will however go back to the default values if reset.
Commands marked with D (dangerous) alter the operation of the
Multifunction Vehicle Bus or stop it completely. Consider the
operative situation carefully before using these commands on board
a train with an active system running.
