Headlights, turn signals, door locks (via keyless) just stopped working.

Headlights, turn signals, door locks (via keyless) just stopped working, also door lock switch seems inop. Car starts and goes into gear. Hazard lights work. And external temp gauge does not work. I have not checked the fuses yet but that seems impossible due to all the separation.

Need to solve this as night is approaching

Do you
have the same problem?

The next thing would be to look at the immobilizer but that would only be if the car were not starting. The bottom line is that getting the trouble codes pulled will be the next step in diagnosing the situation. We are still headed down the right tract.

I had thought about it some more and it might very well be an issue with the anti-theft system or the immobilizer. If you are still having issues let me know and we can pursue that path.

Hey did you guys figure out this problem? My 2007 Odyssey had almost the identical symptoms last night. TMy 2007 Odyssey's Bright lights, turn signals, temperture gauge, both power sliding doors, my back windshild wiper, gauge lights flicker, intermitent wipers don't work, wipers in regular speed operate in fast speed, and fluids all stopped working at the same time. All fuses checked, no go. Stopped and restarted van, again no go. Went to parts store - no codes are showing up, Battery, Starter, and Alternator test fine.

I am assuming resetting the immobilizer fixed it. You have to go to an Advance Auto ro Auto Zone and get aOBD scanner to be able to reset codes or they do it for free.

Looks like I made a mistake in my wording. I said "no go, " when I meant that solution didnt work. Actually the engine runs fine. And there were no codes when tested at AutoZone this morning. If the engine runs fine, it wouldn't be the imbolizer would it?

Hi everyone. The solution to my original post is still not found. However we have done some testing. The dealership has replaced the battery but the Electrical Problem still occurs after a steady or heavy rain storm. So when the van is parked outside during weather like it was when my wife was at work. The same issues appear and it takes a while to correct if at all.

To be clear:
1. Key fob and battery are OK
2. All fuses check out.
3. There is no wire short or burning smell to be found.
4. Dealership was not helpful as to "its not doing it now" during the service visit.

Van is currently in for a A1/A2 service. Hopefully it happens during its time in the shop.

Thanks for everyones input.

Interesting. My '07 seems to have near identical issue. Although this is the 1st time mine has happens. And it has been raining for 2 days straight. But issues are: dash light kinda flicker, power locks don't work, outside temp gauge doesn't work, brights don't work, rear wiper not working, intermittent wiper not working, wiper on slow runs fast, power windows don't work after shutting off engine and accessory but before openning door, and power doors don't work.

DrCranknWrench. Do you have anything for us? I did call the Honda dealer and they said they hadn't heard of this issue before. So it isn't a recall yet or maybe not an item that has hit multitudes of owners. But the fact that this similar yet very goofy issue is happening to at least 2 of us here (and I found similar postings elsewhere online) so there is something common here. And hopefully simple. Do you have access to any Technical Service Bulletin type stuff or anything?

Whew hew! Just got off the phone with a mechanic from church. He said the problem is a sensor inside the drivers side door panel. He is going to get me the specifics tomorrow. But said all I have to do is get it out, clean and dry it, then re seal it so tjat it doesnt get wet again!

I think it could be the master switch for all the locks.

I'm all fixed! There is a Honda TSB on it. Pull off the interior panel on the rear left hand side. Just inside of where the taillight is. It's a connector for the wiring harness. It's wet. Dry that puppy off. Seal it. And all fixed! To test you're on the right connector just pull it apart and 90% of those ghost issues are fixed. But dry it, reconnect and all is fixed!

That is great news. TSB is a good source. Www. NHSTA. Gov, is also a good place to pull that sort of stuff.
I am really glad to hear it is working for you and all is well.

Hello
Can you please tell exactly where this connector is? Is it where the jack is located?
My van is doing the same thing.
Thanks!

Customer came into my shop with the Same problem with 2007 Honda Odyssey.
Did the connector behind the spare tire. And no fix. No water.
Traced problem to Multi-Plex ( Cabin Fuse Panel ) Water leaked onto panel, shorted our fuse block/ panel. Replaced and all fixed. Wish it was as easy and you all had, would of saved me a few hours of Diag time.

To TommyBoy37. My 2003 Honda Oddesey does the same things. For 2 years now each system takes turns flaking out. My cruise control works 200 miles, stops 600 miles and starts up again. Wiper fluid works in front, not back, then switches, then ok. Power sliding rear doors open, but when closing they just roll back and forth until you force them shut. Remote keyless never worked. Power windows only driver side works now, back two "wings" are stuck in open and are currently covered with duck tape to keep rain/snow out of van. Now neither front door opens with key, but rear door does. And yesterday the speedometer and tachometer jumped like crazy, then all "idiot" lights were popping off/on and after I pulled over, couldnt restart car.

@ DOREEN WRIGHT - I had the same problem with speedometer, tachometer and dashboard lights going nuts, dead battery after shutdown and it ended up being a bad alternator. You may have two different issues.

I recently had the same problem after heavy rains. No power door locks, no headlights, no turn signals, no intermittent wipers, no rear wiper. I did a lot of reviewing wiring diagrams, testing voltages here and there and finally with some suggestions from other forums came to the conclusion that it must be one of the MICU units. They are control units where at least a half a dozen wiring harnesses come together and are controlled by a communication bus. There is one integrated in the driver's kick panel fuse box. There is another in the rear passenger side behind the panel in the rear heater/tail light area. I found that there was water in the front MICU. Removed it, cleaned all connections (some were corroded) but still no luck. Then, I did the same for the rear which also had water on it! What a leaky van. Anyway, after that everything came to life. If just one of the communication bus wires is wet it will halt all related body control functions. Even seemingly simple things like wipers are all controlled via a communications bus. Hope this helps people.
