The B1 means change the oil and rotate the tires and check a bunch of stuff. The 6 means change the rear differential fluid in your 4wd. It's in the owner's manual. Dave

SOURCE: engine light on dash stays on.

There are two lights you may be getting confused. There is the check engine light and the maintanence required light. The maint req. light can be manually reset by holding down the trip meter button then turning your ignition key forward. You have to hold the button down until the light goes away.
If it is the check engine light you should run a daignostic check for the listed codes.

Resetting the Engine Oil Life
Indicator

Your dealer will reset the display
after completing the required
maintenance service. You will see
‘‘OIL LIFE 100 %’’ on the odometer/
trip meter display the next time you
turn the ignition switch to the ON
(II) position.

If maintenance service is done by
someone other than your dealer,
reset the maintenance minder as
follows:

1. Turn the ignition switch to the ON
(II) position.

2. Press the Select/Reset knob until
the engine oil life indicator is
displayed.

3. Press the Select/Reset knob for
more than 10 seconds. The engine
oil life indicator and the
maintenance item code(s) will
blink.

4. Press the Select/Reset knob for
more than 5 seconds. The
maintenance items code(s) will
disappear, and the engine oil life
will reset to ‘‘100.’’

Important Maintenance
Precautions

If you have the required service
done but do not reset the display, or
reset the display without doing the
service, the system will not show the
proper maintenance intervals. This
can lead to seriousmechanical
problems because you will no longer
have an accurate record of when
maintenance is needed.
Your authorized Honda dealer
knows your vehicle best and can
provide competent, efficient service.
However, service at a dealer is not
mandatory to keep your warranties
in effect. Maintenance may be done
by any qualified service facility or
person who is skilled in this type of
automotive service. Make sure to
have the service facility or person
reset the display as previously
described. Keep all receipts as proof
of completion, and have the person
who does the work fill out the
maintenance record. Check your
warranty booklet for more
information.

Check with other dealers and do more internet research on the issue. It's a common problem with 03-04 Accords. We got ours replaced for free (if you're paying it can be a $600-$800 job) back in Sep 08 when car had 85K miles.

Look in to the owners manual. There is a chapter around oil change or dash indicators section. There is a step by step way to turn it off. Find it in the book and you will have it off in no time.
