The warning lights are on for the battery, and the brake light, and all the doors are on. A Google search comes up with a bad alternator.
Hello. Coincidentally, I also have a 2003 Honda Odyssey. From my own experience and as a certified auto technician, I can say that when all of these lights are on, it does indeed indicate an issue with the alternator. A certified technician, like one from YourMechanic, will be able to assist you in replacing the alternator.
