Has there been any movement on a way to disable this "feature" permanently?
Unfortunately my 2019 Elite the Auto Idle Stop works like it was intended but I have electronics that reset every time it activates due to the voltage drop and this causes occasional corruption of the devices.
I try to remember to disable it but sometimes I don't.

Any updates?

I'm glad this helps everyone. I have not been able to figure out the reverse to disable due to time, limited driving, kids, life... so I don't have any updates yet. Also, my AIS seems to work fine till sometime over the winter months when it quits working. As the system has so many variable when NOT to kick in, I have no idea when it breaks because I can go a few weeks and it does not work but then one day kicks in. So by the time I do think it is not working, I have no idea what triggered it to stop. Incidentally, winter is generally the only time I will use the remote start system... I continue to monitor the AIS and will definitely post back here if I find anything that may trigger a shutoff of the system.

By the logic of this posting and (know that this fix worked for me) this feature can be permanently deactivated by opening the hood while the car is running and then closing it without shutting the engine. That is when my engine idle stop stopped working. I just wanted to listen and check the engine running. Good luck!

Thank you, thank you, thank you!!!!
This is the legit fix.
I tried this and it worked.
This is how you disable the annoying Auto idle engine shutoff!!!

THANK YOU!!!!
THIS WAS THE FIX!!!!

Why not just disable it as part of the start up procedure….this “fix” is kinda like complicating something that really ain’t complicated

 

[simchas]

start-up procedure? You're kidding, right?

Pretty much everyone agrees that this "feature" is really only a nuisance at best. Having said that, do I have to program myself to hit an extra button now during my "startup procedure" ? I don't think so.
If this fix is all that it takes, I am more than happy to do it.
Pop the hood one time and be good to go vs. pushing an extra button EVERY time? Does not sound complicated to me

I'm sure no one wants to be pushing that button every time.

If the Odyssey ever becomes electric (yech), will it still come with AIS,?!? Stupid Honda engineers!

Firstly, Hi. I created an account just to be able to post my solution this auto idle stop issue. It worked for me on my odyssey and I felt I needed to share. Apologies for the long intro as I feel it’s important to see how I got to this point. Feel free to skip to the procedure - I probably would D.

History: I purchased an elite in June, AIS worked for a day and stopped for about 2 weeks. Then mid-July it started working. My son had messed with the cabin control and I had been in the engine bay for adding washer fluid that day. It worked flawlessly when conditions were met till end of October when I took it in for a service. The entire winter it was not working and after 2x 6.5 hour drives, I decided it must be broken like others have reported. I read through the manual a couple times and came to the conclusion I must be hitting the interior cabin humidity. I left it in the sun a few days to see if that would help clear any cabin humidity. Turns out it was not that. I read the manual again and read about the safety of it not working while the hood was up. This got me thinking, it went in for an oil change, and what do mechanics sometimes do? They start the car with the hood up, do a final check and close up and drive the car out the lot for me to pick up. So, I decided to try the method I will mention below. Well, it at first appeared not to solve it but turns out the van was not warm enough to trigger. 2 days go by and no driving due to snow storm. First trip out, get kids from school and head off, van chimes for software update and suddenly AIS is working. What?? So now I don’t know if what I did or the software update fixed AIS. Anyways a couple days pass and I tried something I was curious about regarding the safety features and then AIS is no longer working again. I traveled this one route many times and I know it works on this route. So I try my procedure again, take the van out immediately and come to a stop. Bingo! Shutoff – procedure seems to work.

Procedure to try fix AIS:

1. Take your van out for at least a 15 min trip and be sure it’s warmed up. If you have the message popup activated, confirm that is says unavailable when you come to a stop.
2. Park somewhere safe, shutoff the van. Open the door and pop the hood.
3. Get out and open it up and prop it up on the kickstand.
4. Get back to the seat, start the car, close the door, confirm the message center says hood open.
5. I got out the van, looked at engine and then went back and shut it off. I think I left the door open and leaned in to turn off, and then returned to shut the hood. (not sure if door open/close played a role yet)
6. Get in, close the door and start normally.
7. Take it out for a drive, and AIS should work instantly, assuming all conditions are met.

Theory: I believe there may be a logic flaw in the AIS safety shut-off system. From what I can deduce from the manual, the hood and driver’s door have some safety features that de-activates the system. Where the flaw is, I believe, is there is no logic to re-check that the safety conditions are met and to reactivate AIS. So you have to trigger the safety (start engine while hood open) and then complete the correct software steps to reactivate the system (shut off engine, close hood). This is probably why it begins working again for a few after services as the safety got reset accidentally/correctly. I'm not saying this theory is true, it's just my best guess as to what is possibly happening.


Conditions that might cause it to stop working: I theorize 2 conditions that I believe may have caused mine to stop working. I can’t confirm as I’m not 100% sure that this is what exactly happened and I have not had time to test these theories and see if either does indeed cause it to stop working.

1. Start the van with the hood open, close it and drive off. (what I think happened after the oil change)
2. Come to a stop have AIS in activation mode (engine off green icon lit), open driver’s door and pop your seat-belt. (what I think caused it the second time when testing that safety and what then confirmed the procedure above worked for me)

Experiment time: I would like others who are convinced they are meeting the requirements for AIS to activate to give this a try and report back if it worked. If it does not, thanks for trying.

Thanks for reading. I do hope this procedure works for you as it did for me.

After three weeks of trying everything else this procedure WORKED FOR ME! Had prior work done which probably led to the problem originally. If this can be done in reverse it might be a reasonable solution for those who would like to disable the auto idle stop. Thanks so much!!!

I found out that AIS always works after I started using Battery Tender to charge battery during the pandemic. As long as weather is not too cold, or too hot.

So I guess if AIS isn’t working at normal conditions, your battery might be too weak, and system doesn’t want to you stuck at traffic light.

Your fix worked for me, too! Thanks so much. I want any feature that may save even a little bit of gas to be working!!!!!

 

[velvetS]

Okay, so your fix worked for a short period of time. The next time I drove the van, it didn’t work again. I just tried the fix again…and this time it did not work. There must be something else going on here.

Your fix worked for me, thanks for sharing!

Dang: this worked! Thanks. How did you ever figure this out, why on earth does it work, and why is it even necessary?

This just worked on my 2024 that hasn't worked for the 1st 100 miles. I just popped the hood started it, received the error message then closed it and restarted has been flawless since. Thank you much sharing to spread the word.
