    EVAP seal test is dark grayed out. 2010 Buick Lacrosse. I cannot perform a seal test. Other EVAP tests are functional. Is the seal test not funtional on a 2010 ?

    There is a workaround if you go to your other EVAP tests and close your vent and open
    the purge valve, then watch the live data to see if your fuel tank pressure changes, that
    should tell you if your seal is good or not .Also close the purge valve after you let it run
    for a few minutes and see if your pressure holds.
