hi iv got a ford fiesta rst OFAC management on my car, i was looking on auto data to day and see you can use a flasher led tool to read the fault codes stored on the ecu though the 3 pin diagnostic socket. any one no where i can get the too from or do you just use a LED?

 

If it's anything like Weber management you can use a LED combined with a resistor (Around 1K is sufficent), or just get a 12V LED to start with! Yes there is a tool as well, I actually saw one for sale not long back.
