Hi Sirs, my ride is a Honda Odyssey '95. For the past 2 weeks, sometimes the battery and catalytic converter warning lights will go on at the same time and off after a few seconds. So far it happens when I shift from park to reverse or drive. After it goes off, it won't indicate again while driving the rest of the way. Once I start the engine again, it will show again also with the same conditions as mentioned above.

Any ideas?

Thanks.
