Hi:

The P1600 code is usually a IMA fault, and the P1449 code is a battery deviation fault.
Both are usually early warning of some sort of hybrid battery issues.
You need to have a system tech give the hybrid system a good look over, but most likely your IMA battery pack is most likely suspect

Hello there,

Apparently, from here http://www.greenhybrid.com/discuss/f50/help-p1600-p1433-28749/
This means the battery is on the way out !!!!!
and here another forum
' Okay got your answer. p1600 is generic telling you there is a manufacture specific code and that becasue of the p1433.. This code is becasue of weak batteries. You will need to plan on battaries soon. They are spendy.'

Sorry friend this is gonna cost thousands :(

This battery guy says he will provide assistance http://www.hybridbatterysolutions.co.uk/common-fault-codes-honda-civic-hybrid/

The P1600 is a generic OBD II code. It just means that a more specific code (Honda) has been set. To find the specific code you have to take it to the dealer or have a Vetronics Mastertech scan tool to get the actual code. The P1433 indicates thats the the main battery contactor or the by-pass contactor is staying active when it should not. Using an Actron pocket code reader will only read generic OBD II codes. Hope this helps.

Error Code: P0A7F/78.
Description: Battery module deterioration.
Solution:
-Check for poor connections or loose terminals at the battery
module, the battery current sensor, and the BCM module.

I think the dealers codes.

I have a 2006 Honda Civic Hybrid and have had hell with it. I have also learnt much about it too.

One thing bad about the HCH2, is that the 12V battery controls the electronics, and the Hybrid battery charges the 12V battery. However the 12V battery is not charged all the time, and cannot be charged when the IMA is usually being used, and in different scenarios. (Buy a Electronic volt meter which plugs into the 12V adapter $14 Walmart))

It is possible that the 12V battery is being drained while driving and caused a voltage drop which can cause your problem. In your case, I would change the 12V battery anyway as they do not last long on Hybrids. (You may have to get Honda to trip the IMA warning lights.) In my case, changing the 12v battery helped the hybrid battery as it was the electronics reporting the charge level wrong.

Depending where you live, you will have a minimum 80,000 mile warranty on the hybrid battery.

Integrated Motor Assist (IMA) hybrid system uses high output electric motor-generator providing more efficient engine operation by capturing electrical energy during braking or deceleration and use of that energy to power the vehicle hence saving valuable fuel. The engine shut off during stops further increases efficiency of the vehicle. This can cause Damage to the Battery System if left UnRepaired for Too Long. Please Rate My Response! Thanks!

those codes are thrown when there is a momentary hicup in the electrical delivery from the battery pack. clear the codes and drive it, if they dont come back you are all good, it they do come back then you most likely have a corrosion issue between the battery monitor system and the battery

DTC P1433 Battery Module Deterioration, need to replace the battery module. Info from HDS more info... [email protected]
