#1230 of 1535 P1600 and P1449 Codes
Nov 30, 2011 (9:35 am)
I have a 2003 Honda Civic Hybrid Automatic at 107k miles on it. I was driving Home and all of sudden in middle of drive, IMA and CEL light came on. So I went direct to Autozone to check code. The Codes were, P1600 and P1449.
The Vehicle runs fine with Charge and Assist happening, but the Hybrid battery charge level indication is showing full and goes to half way and to full. I did check on web for P1449 stating battery issue, so should i need to replace it completely? how much usually cost?
Should i go to dealer?
Note: Prior to this 3 months earlier in August, I had P1600, P1601, P1435 and P1570 and replaced with a MCM module and everything was working fine since then. Now this issue.
Any suggestions please how to proceed?

i complained for a 2nd time with Honda USA and they wouldn't do anything about doing another diagnostic because i was getting recals like 8-10 times a day. i filed a small claims a week later and they called back and said "hey, you willing to take your car to dealership to have it checked out since the last time was in january?".
uh, why didn't you A-holes agree to it before a lawsuit?
well, i am going to go with the technician for the test drive and have them drive it for an HOUR and experience the crap that i experience. the lack of IMA assist during recal, recal many, many times (up to every 7-10 min), lack of efficiency, all the crap!!!
i want him to try and accelerate onto freeway traffic like i do when i had my family and risking their lives!

The warranty will not be honored if a new ima battery is installed and the software update is not done.

this is a joke..u are to be given 100 to 200.00 depending which class u fall into
if u sell or trade in ur HCH on another Honda u get a rebate of 1000 to 1500 depending on which class u belong in.

2003-2005 Civics are a different car than 2006-2009 Civics. The "update" that the 2006-2009 owners are having trouble with is not the same as the maintenance update they put in your car. The latest update for the 2003-2005 Civics concentrates on keeping the battery half full. Gas mileage is affected slightly if you tend to drive fast or lots of local driving or lots of acceleration (if your battery isn't normally more than half full). This is just simply due to it applying more regen than it used to. Gentle highway driving should be unchanged, and the total mpg drop shouldn't be more than a few mpg.
Typically, a CVT owner should see a drop from 60 combined to about 55 combined with a low of 45 local. This update is a general battery longevity change that was also introduced into the 2000-2006 Insight.
The software update for 2006-2009 Civics is essentially the 2010-2011 software applied to the earlier cars. It significantly affects the way the car performs whenever the battery is low, and this in turn severely affects the mpg of some drivers, while affecting others not at all. It all depends on how the car is driven.
Now as to why your battery failed: it has become apparent over the last few years that Honda's battery system is extremely sensitive to be left sitting - undriven. The short version is that every time you leave the car parked for a few days it does a little bit of damage to the battery and this damage in cumulative. The time it sat in your driveway should not have been enough to cause the issue, but your car probably had a severely imbalanced cell (of the 120) and when you restarted the car, it was so far out of balance that a P1568 error was thrown. Your dealer doesn't have a clue about the IMA system, so they'd have no way of knowing why it failed.
Do you know your new error codes?
BTW, your warranty is 84,000 miles, not 80,000.

The dealer was telling the truth about one thing: low rolling resistance tires do make a large difference in mpg. LRR tires typically account for a 5 mpg difference on Civics and tire pressure another 3 mpg. It is safe on all tires to inflate them as high as the "max pressure" number on the side of the tire. Typically that is 44 psi (some are 34). The burst pressure is over 200 psi.
Car manufacturers specify lower pressure because is make a softer ride and that sells cars.
Higher pressure in the tires will increase mpg and possibly your traction, but will make a harsher ride. However, you can try it, and if you don't like it, just let some out until you find an acceptable pressure.

P1433 is a warning (not failure) that the IMA battery is degraded and below 10% of its original capacity - it's worn out. The symptoms are a normal-acting battery that is very quickly depleted and recharged (because it doesn't hold much charge). The dealer should have replaced it. Resetting the system will make the car forget about it and force it to re-evaluate the battery which can take some time. Unfortunately, a battery that is that weak is susceptible to becoming unbalanced, so typically a P1433 is followed by a total IMA failure about 2 months later.
The O2 sensor update that you had done is a software update to the ECU (by the passenger's feet). IMA updates reprogram the MCM (behind the back seat). There was no reason for the dealer to update the MCM, so he probably didn't.

The warranty is on the car, not the owner.
P0A7F is a "replace the battery" code equivalent to a P1433 error. Get it done (free) ASAP.

P1435 and P1570 are problems with the IMA computer or wiring and are not related to the battery. P1449 is a battery failure. P1600 and P1601 just mean the IMA light has been turned on.
You need to repair or replace your battery soon. A dealer is expensive, but there are alternatives out there. Either search on the web, or email me for more information.

This is why I always chuckle when people get all worked up about a car problem and start thinking about class action suits. Honestly, I get a couple of notices in the mail every year to join in some class action or other that someone has started somewhere about a product I own. I now just toss them in the garbage. Right off the top, the settlement, when spread over the number of members "in the class" is pretty much always VERY small. (I got $1.26 as compensation for a small issue with a washing machine once, no "fix" was ever done to the machines, and that was the end of that) The only ones making money are the lawyers, and all the fuss pretty much leads to higher product prices. Face it, if you were Honda and just had to pay out a settlement to a group of people who just "won", how would YOU get that money back?
