    On page 380, there's a section explaining that the OBD II system may not be ready after a recent service

    Normally, the OBD II system will be ready. The OBD II
    system may not be ready if your vehicle was recently
    serviced, recently had a dead battery or a battery replacement. If the OBD II system should be determined not
    ready for the I/M test, your vehicle may fail the test.
    Your vehicle has a simple ignition key-actuated test,
    which you can use prior to going to the test station. To
    check if your vehicle’s OBD II system is ready, you must
    do the following:
    1. Turn the ignition switch to the ON position, but do not
    crank or start the engine.
    2. If you crank or start the engine, you will have to start
    this test over.
    3. As soon as you turn the ignition switch to the ON
    position, you will see the MIL symbol come on as part of
    a normal bulb check.
    4. Approximately 15 seconds later, one of two things will
    happen:
    a. The MIL will flash for about 10 seconds and then
    return to being fully illuminated until you turn OFF
    the ignition or start the engine. This means that your
    vehicle’s OBD II system is not ready and you should
    not proceed to the I/M station.
    b. The MIL will not flash at all and will remain fully
    illuminated until you turn OFF the ignition or start the
    engine. This means that your vehicle’s OBD II system
    is ready and you can proceed to the I/M station.
    If your OBD II system is not ready, you should see your
    authorized dealer or repair facility. If your vehicle was
    recently serviced or had a battery failure or replacement,
    you may need to do nothing more than drive your
    vehicle as you normally would in order for your OBD II
    system to update. A recheck with the above test routine
    may then indicate that the system is now ready.
