Good - I mean the OBDeleven is doing right thing - reading the data. Looks like there is disconnect with the switch (I believe the status is the same with/without ignition on).
However, just verified that OBDeleven does read the data even ignition OFF (and driver's door open for this case). Just takes a little while to connect.
Did the following (IGN OFF, driver door open!!!):
Plugged in the dongle, launched OBDeleven
Takes a while to get message "Make sure ignition is on", Continue, Select the vehicle...............(eventually "Connected")
Click Button = down right
Control Units, 09.......... Loading data........... Live data....
