Scania Stoneridge tacho - faulty?

blue estate:
a stone ridge will come up with end of daily drive time at 9 hours regardless of how many 10’s you’ve got left
Why not just do a print out if your unsure how much time you’ve driven :unamused:

He says:

Total CDT = 8h32
Total working time = 14h46.

So according to him his driving hours are less than 9, so still no apparent reason for the unit to alert anything.

@OP: have someone analyze your card. I may be new to tachos but unless there is a serious software fault I can’t see why the tacho would weird out like this. It is seeing something making it think you are out of hours.
