nice progress :-)
If you can't detect vehicle state by listening to regular status CAN
frames, you can check the time since the last poll reply in the per
As poll replies normally come in fast, you should be able to detect a
switch-off by a small timeout, say 3 seconds… probably need to add a
counter, as a single poll may get lost / ignored.
CAN tx errors can be caused by other issues as well, so should generally
not be interpreted that way.
But… are you sure there are no status frames on the bus? Have you done a
can log or tried the re tool?
