If Your Engine light illumiate and flashes on your Ford Fiesta or Focus then this may help.
Just found a web site that will give you the DTC codes for ford fiesta's and ford Focus. Put the code in and it tells you the fault Not sure if i can put the web address on this site. If the admin guys will allow me to then i will. If not put your codes in his thread and i will tell you what the code means.
To get the code put your key in the ignition but do not turn it.
Hold the trip meter button for 10 sec's.
Then turn the ignition key to position II Still holding the button.
Release the button when the word test is displayed.
To get the DTC codes slowly press the button and make a note of the code.
Turn the ignition off again and remove the key. Next time you switch on the display will be normal.
