I just purchased a used 2008 Odyssey Touring with 33k miles. Battery was replaced in 12/09.
Here's what happened:
Purchased Sat night, parked it in my garage and went top bed (checked on it twice!) No lights where left on as my garage was very dark.
Sunday morning went out to garage, opened both side doors with the remote and also the liftgate with the remote then proceeded to configure the seating positions for my 4 kids, took about 1 1/2 hrs to get all carsetas installed. Then wanted to program the memory for the drivers seat. Took about 5 mins to get the seat where I wanted it and the mirrors aligned. During that time the seat stopped adjusting. So I tried to start the vehicle and all I got was a clicking noise. Battery was dead and van would not start. I called the dealer I just purchased from and they said to jump it and bring it in. That maybe the alarm was not activated correctly and drained the battery.
More info: The van has an alarm (factory I think), I have the indicator on the dash (flashes red when activated) and I also have a green indicator light under the steering wheel. 15 mins after beginning my seat configuration I opened the drivers side door and had it opened for a few mins then shut it, when I shut it the car sounded with 5 or 6 quick beeps. this then also happened everytime I closed any of the doors. I thought maybe the alarm was set too sensitive. But why would the alarm arm itself when doors are open. The only alarm activity is the green light under the dash and not the red indicator light on the dash.
This is what that green light does: unlock the van; solid green then approx 2 mins after unlocking the van without starting it or relocking it the green light begins to flash rapidily for approx 20 seconds then switches to a slow steady blink. If I open any of the doors and then close them the van beeps (quick beeps) 5-6 times at me.
Can anyone tell me what's going on? I can't get back to the dealer until saturday due to work.
