Thanks Mike. I hope that you don't think that I was trying
to bait you or anyone else into some sort of argument. Your
credentials are impressive, and I would appreciate your
input on matters such as these. I'm willing to learn.

I used to fail MILs that came at any time during an
inspection other than bulb check, because, well, it's
indicating a malfunction. I was told by more than one update
instructor to concentrate on the activity of the MIL during
the functional phase of the test ONLY, and to basically
ignore it any other time. The functional phase of the MIL
test for this vehicle involves finishing the emissions
portion, turning the ignition off long enough for the PCM to
sleep (15 seconds is usually adequate, in my experience),
check for MIL on KOEO, check for MIL extinguish KOER, and
proceed. Passing a MIL-during-emissions test goes against my
instincts, but I have been complying with my instructors'
directives for several years now.
Of course, I have worked in a poor neighborhood for over a
decade, so I have seen nearly every possible permutation of
MIL activity. A question that I asked one of my instructors
was "How long should the MIL extinguish KOER before judging
it as a pass?" His answer was "30 seconds should be long
enough." Since that time, I have literally counted the
seconds before MIL illumination, and passed those which made
it to 30 seconds. There have been numerous close calls, both
ways.
Of course, this is all hearsay, but it wouldn't have to be
if SCIP was just written in a more complete and specific
manner. You may have already been subjected to my wordy
letter to the STAR program, but I'm attaching it here for
your entertainment and enjoyment. I do my best to address
the issues that were chewing at me last winter, but I may
have gone a little bit overboard on the word count. My
problems with SCIP 1.5.1 appear on page 6. [CA STAR

Oh, it was definitely OBD II. I have made my share of
mistakes, but nothing as glaring as that, at least to the
best of my knowledge.
I know that you are probably a busy man, but if you are
willing to spend the time to educate me on the errors in my
logic, I am more than willing to listen. Who knows, I might
not be the only one out here scratching my head over this
mess, and you could be helping others as well!
