Hi Jon,
On the 2000's, at least on my 2000, disconnecting the battery to reset the
PCM does not reset the station presets. I can't remember if it affects the
clock or not. I'm assuming there's a capacitor in the radio that maintains
these things for short duration outages. Come to think of it I believe the
overhead monitor retains all of its information as well. Hmmmm....guess
I'll check these things out tomorrow.

Jeremy,
No problem; you can "reset" the computer yourself. The dealer just
hooks up a scanner and tells the computer to clear out the codes
(simplified explanation), but since the codes are stored in volitile
RAM, they can be erased by cutting power to the computer. (Sort of
like unplugging an alarm clock and plugging it back in again so it
flashes 12:00.) :-)
Anyway, all you need to do is to disconnect the negative cable
from your battery, then stick your key in the ignition and turn it to
"start". (It won't start, but this should ensure that any residual
current is drained out of the system.) Then, re-connect the negative
battery cable and the check engine light should now be gone. Just as
a word of warning, this will also reset the clock and erase any radio
station presets you may have programmed, so don't be alarmed if that is
the case.
