Best way to test my fault code reader

[bigdods]

So I've got my fault code reader, hooked it up and the display stays dark. So hopefully this is good news and means no stored fault codes. But being a tinkerer I want to check its actually working. So whats the best way to induce a code without knackering anything ? I was thinking of just disconnecting the stepper motor then turning the ignition on, will that cause a fault code ?

Any advice welcome

Cheers

ETA: Never mind, I just disconected the AFM and up popped code 12. It works , no stored codes, all is well in my world :-)

Unplug the ecu and then reconnect it. Next time you turn the ignition on it will show 02 (power reset) just once. Otherwise black is good.
