Almost every time I start the car, the power passenger door opens. On the odd occasion it doesnt, it beeps 3 times.
Tried disconnecting the battery, didnt help
thanks djcoons1

 

Don't know anything much
But, wild guessing, ....
There must be a short from some wire that get power when ignition is turned on
That short goes to the power passenger door

Would need schematics and a bunch of tools to track down ... if that is the issue

 

welcome to the forum: have you tried to reset the power door. Go to Google and find "how to reset an eleectric sliding door on a honda odyssey" i don't copy and paste. sorry.
