Last night around midnight, I was woken up with the sound of the Odyssey alarm going off. I jumped out of bed, grabbed a gun from the safe, had my wife ready to call 911, locked the door behind me, and crept around the corner of the house. At first, I thought the window was busted out. Nope, just a reflection from the floodlights. I silenced the alarm and checked for signs of a break-in. Nothing. I reset the alarm and went back to sleep. About 30 minutes later, I repeated my earlier steps. The 3rd time it happened, I went outside, silenced the alarm, and hit the unlock button on the keyfob so the alarm would not set. The 4th time, after going outside again, I remembered that the doors lock and the alarm sets itself if you hit unlock on the keyfob and do not enter the vehicle in 15(??) seconds. This time I hit unlock and opened the doors. I left it unlocked until I woke up an hour or so later to get ready for work.
What I found was that the door ajar indicator for the passenger side sliding door was on. I played with the door switch and manually closed the door a few times, but the problem is still there.
I went to the dealer earlier this evening, but they could not work me in. I bought a door switch (it was super cheap) and installed it in the parking lot. It did not fix the issue. The passenger side sliding door open indicator is still lit. I did notice that whenever I put my seatbelt (driver) on, the light goes off. As soon as I unbuckle it, the light comes back on. I've opened the driver's side sliding door, and it doesn't matter if my seatbelt is buckled or not, the light stays on. Weird!!!
Anyone have any ideas where to start? I do not have a service manual, but I'd like to know how the seatbelt interfaces with the door ajar feature.
