maintenance light
 

I have a 2001 Honda Odyssey Van.
I had my oil changed from honda a while back and they forgot to reset
the maintenance light so it came on about 500 km later.
I checked the internet to get the steps to reset the maintenance light
and it worked fine.
It seems that the maintenance light does not come on letting me know
that a oil change is due.
The maintenance light does come on when the van is started.
Can anyone suggest what I should do.
I am thinking about dis-connecting the battery making sure that
everything will then reset .
