On your page with the Pre-1996 OBD I KIA information, you say that you can do your own diagnostics and then give the steps. In step 2 you say “Observe the MIL and identify the trouble codes”. What is the MIL? and how do you identify the trouble codes?
MIL – Malfunction Indicator Light(Check Engine Light/Service Engine Soon)
Count the flashes to determine the corresponding number.
example. flash, flash, pause, flash, flash, flash, long pause, would be 23.
Hope this helps.
