it's like Morse code. to test: Key ON/Eng off. Wire in the pin socket. Hold button for 1 sec. then the code will flash.
IF you get 1-1-1 = no fault stored.
Each system can store 3 codes max. So you must check 3 times. To clear the codes, hold the button down for 5 sec, then release-wait for the light to come on-the press the button for 5 sec. again. to verify, key off/key on and test again.

Pin 2 is fuel system 3-2-2 is Mass Airflow sensor Burnoff signal is too low. this could be an old code, as they must be cleared to go away.
Pin 6 is Ignition system
Pin 3 is ABS
