    Your fears are well founded. You will not pass if the MIL is illuminated. See the DTC Sticky to learn how to pull your DTC's. Post them AND their definitions.

    service engine message
    Means
    The on board diagnostics has detected a problem that may effect safety and or reliability.
    It is a bad thing.

    Re: Service vehicle soon

    The SES light/icon is set when an engine or system fault related to emissions control is detected - missing, O2 sensor problems, fuel/air mixture problems, ignition sensors, vacuum leaks, some EVAP faults, and the good ol' TCC problem codes.

    SES has almost nothing to do - directly - with safety or reliability: Those problems are covered by the DIC warning messages and by the hundreds of P, B, C, and U codes NOT related to emissions.

    Why does a torque converter lockup fault trip an emissions code ? Because TCC is part of the overall EPA fuel mileage rating for any of these FWD TCC featured vehicles: A bad TCC decreases gas mileage, thus burning MORE gas per mile, so it's technically an emissions fault - even if your tailpipe emissions do not increase one tiny bit due to the extra engine rpm needed to maintain the same speed.

    For the OP's 2000 model year vehicle the conditions that will set the SES icon - either steady or flashing - are listed in the owner's manual under the DIC sub-chapter.

    I did not read about the light.
    I read about the scrolling message that dominates any other information.
    SERVICE ENGINE SOON
    It goes by from right to left like an airplane towing a banner.
    It does this for important things.
    For not so important things you just get a red light over in the corner.

    I don't think it does that on a 2000 Eldorado. I know it didn't do it on my 98 Seville when I had a misfire in the past due to a bad coil. The amber "Service Engine Soon" light did flash, however.

    My old ones do
    93 thru 95
    If you want to see if they will scroll a message unplug an air bag and turn the key on

    I've never seen a scrolling message either, for whatever that's worth.
