Before the change over to Marseille, the speed limit decreases from 160km/h to 140. If safety systems are active then this will inevitably trigger the emergency brake. There should be a warning on the squares for this, there isn’t, the screen still says 160 in solid implying that the next block is 160km/h. The squares should be flashing 140 before this block.
I don’t think TVM-430 gives an indication for an 140kph speed limit. You are also transitioning from LGV/TVM to KVB/Classic here so I think you just need to be aware (from route knowledge) that the speed is 140kph at this point.
