I have my first hybrid!! And I need help (07' honda civic hybrid)
 
It appears the battery is going out. Im going to get one of the reconditioning packs that are avalable, but not sure is that will do it. The IMA light came on once and then left, and code two codes over voltage spike and abs malfunction. To my understanding the ima battery imbalance or failing causes this and maybe the reconditioning will undo it?

This is an 07' honda civic hybrid, well out of warranty.

Sorry to hear that. I don't know a lot about the system you descibe, but I know that you might want to offer a little more detail about the problem and the proposed fix. This thread seems to discuss your problem: 05 HCH ABS / IMA Lights - GreenHybrid - Hybrid Cars

Today is a holiday, of course, so hang tight and see what responses come today/omorrow.

Well assuming I rule out battery, what else can be done?

It sounds quite strange, an IMA malfunction shouldn't have any relation to the ABS malfunction.

hard to say

Did you resolve your issue with civic?
I would question the 12volt converter and IMA.
The IMA provides voltage to charge the a 12volt battery, and the 12volt electronics. But it uses the 12 volt converter module to step down the voltage.
So if you're having weird failures that don't make sense. Don't overlook the converter as having problems, and or a marginal 12 V battery .
Additional;
I live in Iowa and have a pile of modules and near new IMA from a 2007 civic hibrid.
Between the two of us with might have a car running like new.

IM not far from iowa. Do you think you can do the battery reconditioning with a Hybrid automotive kit(which I have)? I have not solved it, and current I got an Ima code, but it went away after restarting the car. Its odd because it does this thing where it goes down to two bars, charges for a little while, then goes back to full bars, and after some use, skips down to two bars, and does that cycle again. Im guessing a few cells are screwed, but not all.

You're describing recalibrating. I suspect you may have a few weak cells in your pack. As you use charge from the pack, those cells go below a certain cutoff voltage before the others do. When that happens, the system automatically bottoms out the meter and forces a charge cycle on the pack until the pack indicates that it's full. I'm not 100% on the processes at play here and if EM member S Keith comes on and says something different, listen to him. It was his guidance that walked me through getting my pack back in order.

I purchased a grid charger from Hybrid Revolt and wired it in. Took an afternoon - evening, really, and it was cold, and it didn't take long. That kept my system working okay for a while. Then I started getting more and more recals and the IMA light came on and stayed on. Obviously grid charging, while helpful, isn't everything you need.

Then I followed instructions to build a discharger. Following (some of, because I am a bit pigheaded that way) S Keith's advice I pulled the entire pack down to a total of about 55v DC. S Keith told me he has discharged packs all the way down to 2.0V DC, which is about as dead as a battery can get when you consider that total of 2.0 volts is coming from 144 cells. Done gently, it doesn't harm the cells. I have been enjoying a nearly-new performing IMA battery, though it seems to me that it's begun to get a little out of balance again and the next time I do the discharge, I'll pull it deeper.

I think your HCH is a generation newer than mine, but this was the process I followed when I was experiencing some symptoms similar to yours, and it has been working well since. For a few bucks building a discharger is easy.

Also: Honda hybrids tend to throw a whole mishmash of codes when the 12v battery is bad or ground straps are bad.

I would try it with a known good 12v and inspect your grounds as a very first step.

OP is in Nebraska, Zed. 50% off won't cover shipping the car to the UK.
