The codes that can be read from the trip display are only dashboard codes.
You can't read OBDII from there. The sort of information you get is engine
temperature, battery voltage, speed in both MPH and KPH and so on.
In order to view this, with the ignition switched off hold down the trip
reset button. Whilst keeping the button depressed, start the engine. When
the trip display reads "TEST" release the button. The dials will self-test
by going to maximum display, then minimum, and will then read normally. You
can then repeatedly press the trip reset button to cycle through a whole
load of information. Some of this is obvious, some quite obscure.
A Google will reveal what the less obvious codes are.
Every Focus I've ever tried this on shows the code to indicate the fuel
gauge sender is faulty....
