I would say yes, the problem is solved. The relay replaced was for the A/C compressor. It is located under the hood, drivers side, in the fuse and relay box. My mileage is down to 46.5 mpg, which is due to using the window defogger quite a bit this season. Note, I never got the software update that was recommended by Honda. I am going to to a odometer vs. mile marker comparison on the next long interstate run. Since the defogger is run from the A/C in a heat pump mode, finding the problem was a bit of a minor necessity beyond the IMA problem. I currently have 148,000 miles on the car. which is over 10,000 miles since the start of the troubleshooting, and 6,000 miles since the relay was replaced. This may not be the solution to all IMA problems, but for $14 it is a good starting point. To keep people up to date concerning this fix, my car is a 2005 civic hybrid model.

Please contact me privately to discuss how to disable the faulty IMA battery and bypass it in your 2000 Insight. I'll provide you with instructions on how to do it and also diagnostic steps to find out why the car wouldn't start with the breaker off (it should have).
Before anyone else asks, this can only be done on 2000-2006 Insights, not on Civics or Accords.

Yes, but which relay? I believe there are two related to the AC in that box. This problem is rare and is not actually related to the IMA system, but I have seen it in three other cars.

So, last I posted, my local Honda dealership told me Honda was working on a fix for the update problems and they should be available this week. Just as I was planning on calling to check on the fix, my IMA and engine lights came on again. Since I was just starting on my list of errands and places I had to be that day, I didn't drive in to Honda service until I had driven 25 miles with the lights on. Interestingly, during that 25 miles, my mpg went up from 27.3 to 28.1 going up and down "hills" where I live. In addition, the auto stop was working, the green charging bars came on when I took my foot off the pedal or depressed the brake, and, while my battery gauge depleted going up a hill (3/10 mile), it recharged within a mile. In other words, the car was acting more like its original performance after the engine and IMA lights came on. Unfortunately, it still didn't have the power back. I was almost considering NOT taking it in, but I didn't want to give any excuse for not covering any warranty issues.
Anyway, I received a call later that night, and the service rep I had been dealing with from the beginning told me the district service manager had come out to look into my car situation, and he ordered me a new IMA battery. Okay, I'm game. I don't think that's going to make a difference, but ok, it's one more step towards meeting the lemon law requirements if it doesn't work.
When I went to pick up the car tonight, my service rep informed me that my car was the last software update. Honda was no longer doing the software update because of the problems. Yee haw! He told me that the new IMA battery is installed and, as I understand it, eveything is back to the original status. Time will tell, but on the way home, the auto stop worked, the battery recharger worked, the battery gauge only went half way down going up a long hill, AND I had power in acceleration. We stopped to fill the tank to get a reading on this battery and it currently reads 38.1 mpg. I'm cautiously optimistic.
SO, those still driving an HCH and experiencing problems, you might want to give your dealership a call and see what the story is now. I live in Washington state (Seattle area), and it may have been a local resolution, but he said, Honda is no longer performing the software updates due to the problems that it caused. I don't know if that means reinstalling the original software, but it's worth a try.
Good luck, and I'll repost after driving for a couple weeks and seeing if indeed things are back to the original performance.

It will be interesting to see if this is a local Washington phenomenon or if Honda has stopped the software update for its operations world-wide.

This is very interesting. Look forward to your updates. I don't see how Honda can just start undoing the update without notifying those who have it.

I would like to know more about this as well. What about those of us who got new batteries, but still panic when we pull out into oncoming traffic, wondering if we will make it?! Is Honda going to reinstall the previous software version? I have demanded this several times to no avail. The software update was not a fix. I have a new IMA battery with about 5,000 miles on it, and my car is still a piece. I get about 35 mpg, instead of the 42 I used to get.

I guess I am fortunate so far. I have both the update software and the new IMA battery and my milage is what it used to be--45-48 mpg.

I brought my HCH 2007 (with software updated and crapy performance after that) this morning to Honda dealership requesting the check-up and demanding that they fix car so IMA assists when going uphill. Anything less is not acceptable and I will consider it as malfunction. I warn them that I have quite often three kids at the back and it is safety issue as well.
Now manager is dealing with it, since the software is "OK".
I will keep you updated.
#895 of 1530 Update to the above message

I got another phone call. Honda engineering is working on the issue with upgrade and solution is expected within a month. There is nothing they can do now.
