Trac Control ('01 lw300)

I was driving home last night and noticed that the light on the traction
control button was off and could not be turned on. All seemed to be running
properly. Pulled over and stopped the engine. Did a walk-around to check
tires and all seemed reasonably inflated.
At key-on, all the dash lights did their tests and the Trac light on the
button stayed on. So far, so good. Three seconds after starting the engine,
the Trac light went off, stayed off and could not be turned on. There were
no service indicators illuminated.

This morning, I opened the hood and pulled (for 15 seconds) the 'Controls
B+' fuse to reset all the computers and dump any codes. All systems back to
normal. Drove 8 miles to work and still good. If it happens again, will get
the codes read out.

Anybody have an idea what may have caused this? Front brake service was done
back in December. Rear brakes may need service soon.

Totally OT portion of message -
Was in the local diner a while back and heard several guys singing Doo-Wop
while waiting for their food to come. I love that music and got talking with
them. They were from a barbershop chorus www.chordsmen.org and asked if I
would like to go to one of their rehearsals. I've been singing for about six
years with my church choir and had been looking to learn more about doing
harmony. Well, this was the place to learn... a capella four part harmony
and sounds pretty amazing. I auditioned and became a member last week.
