Greetings & Salutations
Hello to all,
It seems I go to these forums when I encounter problems with my vehicle (all Honda's) which isn't very often...knock on wood.
I own a 2006 Odyssey, 2007 Accord (4 cyl) and a 2006 Civic (daughter's).
Lately I've been encountering a strange issue with the Accord; the radio, dash lights and tach electrical power interrupts (goes out) intermittently and the red seat belt illuminates simultaneously. Most recently, the orange engine icon went on again for the 2nd time this past month. Although since the car drives ok, I wasn't too concerned. However yesterday, it was raining (very moist) and I encountered the electrical interruptions frequently, approx 6 times in a 5 minute drive travelling 25 mph. My wife drove it last evening and said she encountered the same problems but the car "lurched" so I suspect ignition might be a possible symptom as well.
This issue occurred a couple of months ago but only a couple of times which couldn't be replicated or isolated and only the radio was affected that I observed. I initially thought it was related to the satellite signal.
This morning, I went to Autozone and they tested the battery and alternator. All checked good but since the engine light was on, the code was defined as P0685 ECM/PCM Power Relay Control Circuit / Open.
A little history....several years ago, I encounter severe corrosion on the positive battery terminal in which the car wouldn't start. The tow truck driver replaced the connector with an aftermarket, and everything was fine. So, today I notice the corrosion had returned. I disassembled, cleaned and re-assembled the terminal connector. After reattaching, and starting the car, the engine light was off, entered the radio code and everything seems fine again.
Did I solve the problem? Should I take it to a dealer or enjoy my success and wait and see?

I say you are good to go. I would think about protecting the terminals. There are all kinds of products out there that will slow down the "growth" of crud - real technical there - that you could apply.

Corrosion on + terminal - (follow-up)
Thanks guys for your comments. The more I thought about it, the more I'm thinking that the corrosion caused havoc on the system, especially in damp conditions.
Since yesterday morning after thoroughly cleaning the positive aftermarket terminal lug where the harness connects, there has been no issues. My wife took the car to work. She texted me when she arrived that the engine light wasn't on and the car drove fine with no radio interruptions. Of course the jury is still out until tested in rainy weather, but I'm 99% sure the mystery has been solved.
I suppose I'll just have to keep an eye on it, but I'll let you know if the issue repeats.

Good to hear.
Poor battery connections (all ends of all cables) will cause all kinds of strange electrical issues. So a good cleaning of them and then something to help keep them clean is always a good idea.
Hope that the issue(s) stay away and you can put this o in the books
