Been thinking about this when you unplug something you get a code instantly open circuit when you cycle the ignition.


Does the ecu go through a POST (power on self test) .

Is there a table of what the ecu needs to check
lets say    check ecu hardware... check ok>  check code words... check ok > check physical hardware... check ok

something i would like to learn more about
