Need IMA repair or replacement advice

[zehboss]

The car currently runs with the DC to DC providing 13.8 volts from the HV supplied about 80% of the time, at this time with the IMA switch turned off and the BCM is still connected. Is it the BCM that is turning the DC to DC on and off?

The way the car currently is running I think I could drive a long way since the battery is being maintained most of the time and the car running with the DC to DC off uses about 120 watts as I understand. Will the car run better with the DC to DC off in gas mode until I fix the IMA?

Thanks again for the input.

Disconnect the three bcm connectors, & turn hv switch to off, the 12v will charge between ~ 1,300 & 3,800 rpm.

Above 3,800 rpm brake & charging light will turn on and charging will drop out for ~ 45 seconds.

I have driven like this for a year and a half. No big deal.

Thanks so much for the real world information.

The car is running great with the IMA off. I got 51 mpg gas only on the last trip. I will be working on the IMA next. Thanks again for the assistance. This forum is great.

Hi,
Great thread which I need to sit down and really study. Regarding the warranty situation I just got off the phone(3/1/2013)with our local Honda dealer who stated a similar restriction on warranties on battery replacements done under warranty. He states that the warranty on the new battery would expire when the vehicle warranty expires which had been bumped up to 10 yrs and 150,000 miles under service bulletin 06-057

My 2001 insight battery was replaced under the extended warranty in 2010 (for previous owner) That battery is now a goner with P1600 p1601 p1447 and p1449 codes. They are offering to replace the battery for $2731 with a 12 month warranty.

Does this sound correct that a battery replaced in 2010 would not be under warranty less than 3 years later because the vehicle warranty had expired?

For that price (or actually, a bit less) you could have an upgraded aftermarket battery installed and it would have a 2 year warranty.

I'm a noobie. Stumbled across a 2004 CVT w/ 125.2K, CEL & IMA lights on. Bought it for $2K after I verified the VIN was covered by Honda's extended IMA warranty.
I'm not certain but I thought they told me 10yrs/157.5K miles - which is a weird number but thats what I heard.

Your Insight is covered by a class action ruling that increased the warranty distance limit from 150,000 to 157,500 due to odometer inaccuracy.

Ah, thank you sir. I thought I had the right number!
However, I have just created a potential problem for myself. I've only had the car for a week. I killed the 12v battery by leaving the hatch open on a cold MN day not knowing there was a little light in there.
I had to charge the 12v to drive the car so I disconnected the battery and put the charger on. After a day of charging, I connected the battery back and suddenly no more CEL or IMA lights. I drove the car for the first time since I owned it with IMA assisting and charging. I felt the regen for the first time and freaked out briefly when the auto engine stop worked for the first time.
Driving 30 miles round trip to my sister's gave me a reading of about 90% or more charge.
So what's the problem?
The problem is I have an appointment at the Honda dealership where the car was originally purchased and serviced by the 1st and 2nd owners. The previous owner recently took the car in for a CEL and the dealership reported codes P1600, 1601, 1447, & 1449.
I don't know what all those codes are for exactly but they told her she needed to replace her IMA battery module.
They gave her a written estimate for about $2,500 - she declined and put the car up for sale.
After doing some research on this site I was able to verify with the dealership that the VIN on the car was covered so I bought it knowing I would have the repair covered.
However everything seems to be working as it should. In fact, it seems too good to be true.
If I knew then, what I know now after disconnecting and charging the 12v I wouldn't have done it and just limped to the dealership on Tuesday morning.
What's happening? Is this only short term? How do I get the warning lights back on so I can get the IMA warranty work done? (You can't tell I'm a bit panicked, can you?)
Thanks in advance!
Sincerely, John

The dealer already knows about the codes, so they should complete the warranty repair even though the DTC's are no longer stored because you disconnected the 12 v. battery. Just explain what happened and you should be OK. But if not, the DTC's will return shortly.
