2008 Civic IMA Issues
Edit
|
I'm no expert, but I would probably start with a grid charger if you want to keep this simple. Otherwise you'll have to pull out the pack and evaluate the cells.

It seems like it would make more sense to fix it since it has relatively low miles on it, than to sell it. You're gonna get maybe five grand for it, and that will just buy you somebody else's problem car.
As long as the CVT is holding out I'd either get the grid charger or see if anybody in your area works on the battery packs. There's a guy in my area that rebuilds them for like half of the price the dealer quoted you Wait a minute! Since you're from Kentucky, doesn't it make more sense to fix it by putting a piece of electrical tape over the IMA light? |
Depends on the ima codes. Could be a bad BCM, PTC strip or a thermal issue.
Maybe the blower is acting up or the intake is clogged? |

I would start out by checking or even replacing the 12v starter battery, from what I understand if the 12v battery is on it's last legs everything will act fine but the light will come on, of course the dealership should have checked that... but they don't always do things like that.
Most auto part stores around here will load test the 12v battery to see if it's good, they should also be able to plug in an OBDII reader and tell you what the other codes are. |
http://ecomodder.com/forum/showthrea...vic-13610.html A P1447 & P1449 means the battery is worn out. Its less than 10% of its original capacity. The P1449 means over heated battery pack. :eek:

After you get the codes, disconnecting the 12 volt battery for a few minutes will reset the car and may make it "driveable." Some IMA codes are not detrimental, like the one for "excess heat." But driving with those codes makes the car want to baby the IMA battery. Stopping assist or regen, or failing to charge the 12 volt battery. Your battery may still be capable of functioning normally, resetting the cars computers make it behave.

****UPDATE****
So I drove the Hybrid today to work (both IMA and engine lights present in the morning). This afternoon when I drove home, the IMA light was off and engine light was still on. So, I stopped by a local auto parts store. They said they couldn't 'load' test my starter battery but could run the codes. POA7F That was the only code present. Thoughts? |
Okay, the P0A7F is the 2005+ version of a P1447. It means the battery has dropped below 10% of its' original capacity.
A grid charge/maintenance charge will help this. Its likely you got some cells out of balance and they are pooping out before the other cells causing the over all pack to give up the ghost. |

You can build one your self stacking a few led power supplies by mean well. Basically you hook the outputs in serial and the inputs in parallel. You adjust them for a certain voltage depending on your pack and drivers side door jam sticker. Is yours 144 volts? I cant remember which, but one year of HCH they added some extra cells making it 156 volts or so. :eek:

Looks like Hybrid Automotive system is popular.... |
Hey,
I got the Hybrid Automotive grid charger when my 03 HCH started throwing low battery codes. It was a real kick seeing the voltage output slowly climb over the next several hours. Since then I've come to the conclusion that my battery also has a small short in at least one cell, since I've never gotten to the point of ramping down the current to finish off the battery at peak voltage. But even so, whenever I get the low voltage code - I don't even put on the reader anymore, I just see the IMA light and put it on the charger overnight - the grid charger is sufficient to balance the pack enough and usually, with a couple of overnights on the charger, it's good for at least six weeks of IMA light-free driving. That's a lot cheaper than a new pack. I'd love a new pack, especially the upgraded, high-capacity models some places are touting. But this was affordable, so here we are. And it keeps the car's fuel economy in the stratosphere, so it's all gravy to me. |

I've read up on chargers and Hybrids seems to be the way to go. I haven't shopped for a good price but did notice that on ebay they go for about 430+14= $443. Anyone reading wanna chime in on a better place to buy from? Thanks |
You could join the insightcentral.net site and see if you can get one from placing an ad in the want ad section.
If you are going to own a hybrid this is a nice tool to keep its battery in good shape. Think Im the only one with the newer insight that owns and uses one several times a year. Yes, even the new packs get out of balance over time with daily use. |
