We have a 2004 sienna LE since December 2008 with 77,000KM. I am experiencing a problem that I would like some help with. Drove the van for a short time (about 3km)
Parked it for an hour
Came back to start it and the parking brake, low tire pressure warning and the ABS lights came on and stayed on after the van was started.

At this point the van wouldn't shift to drive. I overrode the shift lock to bring the van home and the check engine light came on!

During the drive home I noticed the turn signal lights, power windows and blower did not work.

After about 2km of driving the parking brake, low tire pressure warning and ABS lights went away and the van was back to "Normal"....except now I have the check engine light on.

any ideas as to what may be happening?
